Fertilizer For Green Giant Arborer (GGA)
The most common type of fertilizer used for green giant arbors are:
1. Calcareous Compost (CK) – A high nitrogen compost made from decaying plant material such as leaves, stems, bark etc.
It contains many nutrients which helps plants grow faster and better than regular soil based fertilizers.
2. Lime – A mineral which acts as a natural fertilizer for plants.
It also improves soil structure and keeps it moist. It is added to lime based fertilizers to improve their effectiveness.
3. Nitrogen – A basic nutrient required by all living things including humans and other animals.
It is necessary for growth, development, reproduction, tissue repair and immunity among others functions.
4. Potash – A naturally occurring element found in rocks and soil.
It is a vital component of many soil components, especially organic matter. It contributes to the formation of humus and promotes the growth of certain plants.
5. Phosphorus – Also known as phosphorus or phosphate rock, it is one of the three major elements needed for life on earth.
It is a major component of DNA and RNA, essential for all living things and plays a vital role in photosynthesis.
6. Sulphur – Also known as sulphur or brimstone, it is a non-metal element found in rocks, animals, plants and soil etc.
It is an essential element for all living things and an oxidizing agent in compounds like vitamins B and amino acids.
Soil And Arborvitae Fertilizer
Arborvitae is a type of evergreen coniferous tree native to eastern North America and north-western United States. It grows well in tight areas and withstands harsh conditions. They are low maintenance plants which do not need excessive watering, weeding, pruning or staking to grow properly. They thrive well in shade to partial sun conditions and can survive in poor quality soil with minimal nutrients.
Arborvitae is very tolerant of dry and wet conditions, they do not require excessive watering and their soil should be kept moist at all times. The soil where arborvitae are planted should have good drainage although they can grow in poorly drained soil as long as it is not water-logged.
Arborvitae are not heavy feeders hence do not need excessive nutrients or fertilizers. Every two or three years arborvitae can be fertilized using a balanced slow release fertilizer with N-P-K ratio of 5-5-5 or 10-10-10 at half the recommended rate. The best time to fertilize arborvitae is in the early spring which is when they begin to sprout.
Arborvitae prefer acid soil conditions so pine needle tea or mulch helps them thrive well.
What Is A Fertilizer Burn On Arborvitae?
Arborvitae are hardy and can survive in many conditions. However, due to over-fertilizing they may suffer from fertilizer burns which kill the outermost layer of the plant. This is caused by an excessive amount of ammonium nitrogen which is present in some slow-release fertilizers and appears in high concentration when it first starts to break down. This condition can be reversed if caught early.
Fertilizer burn on arborvitae looks different depending on factors such as type and duration of exposure.
1. White Spots – These spots begin as yellow patches on the leaves and then eventually turn into white spots.
The edges of the leaves nearest to the soil are going to be the most affected. This condition is more severe during hot and humid weather conditions such as after a lot of rain.
2. Yellow Patches – Ammonium in the soil gets converted into ammonia which causes these yellow patches on the leaves.
3. Stunted Growth – Due to a limited supply of nutrients, arborvitae may experience stunted growth especially in young and newly planted trees.
4. Whole Plant Affected – In some cases, the whole plant can be affected due to ammonium nitrogen in the soil.
The whole plant may wilt and turn uniformly brownish in color.
5. Foliage Dieback – Foliage on the plant may turn yellow then brown before dying back completely.
6. Excessive Weeds – Some weeds may thrive better than arborvitae when over-fertilized.
7. Soil Erosion – The top layer of soil may get washed or blown away due to rain or irrigation.
8. Root Decay – The nutrient absorption capability of the roots is reduced eventually leading to decay.
9. Soil Structure Damage – Excess nitrogen may also damage the soil structure leading to poor drainage and compaction.
How To Prevent Fertilizer Burn On Arborvitae?
While it is possible to prevent fertilizer burn completely, it isn’t always practical or possible due to different soil conditions. Some arborvitae are more tolerant to over-fertilization than others.
It is best to choose slow-release fertilizers carefully and apply them at a lower concentration. Avoid using ammonium nitrogen based slow-release fertilizers on arborvitae trees. While organic fertilizers are the best, over-application can also cause burn.
With that said it is still important to feed the soil with organic matter such as composted manure or mulch to provide nutrients to arborvitae trees. These are feed the soil, not the plant. You should also avoid frequent applications of fertilizer, soil cultivation or tilling the soil as these practices can destroy the soil structure.
The best approach is to take a organic approach with arborvitae which includes planting them in well-draining, porous soil so there is no need to water them too frequently. Arborvitae should be planted so that the drip line of the tree is just above the soil level to prevent root rot.
Remember that trees fix their own nitrogen so they don’t require heavy applications of synthetic fertilizers.
During the summer months, arborvitae may experience periods when they are actively growing. During these periods, you should increase the amount of water and nutrients given to them. This can be done by watering them every 7 – 10 days and at the same time you can feed with slow-release fertilizer. Alternatively, you can apply a complete water-soluble fertilizer every 7 – 10 days as well.
During the late summer and fall, arborvitae should be fertilized once every three to four months. You should also reduce the frequency of watering at this time because fall is the time for the trees to build up their resources for the winter. In fact, it isn’t uncommon for arborvitae trees to drop most of their leaves during this period.
In the winter, arborvitae trees do not require any fertilizer and should only be watered every two to three months. This is an important period when the roots are dormant and protection should be provided against extreme cold weather and any potential frost or freeze damage. This means that the trees should be placed in areas protected by buildings or pavement or other such wind breaks.
Always use rain water or water straight from the hydrant rather than tap water because it already contains the right mixture of nutrients and ions to keep the soil healthy and prevent any nutrient deficiencies in the arborvitae tree.
Once a month you can also apply a protective mulch around the base of the tree to help conserve moisture and keep down weeds which can compete with the arborvitae for nutrients. Never use grass clippings because these will eventually decay, rot and turn into dirt which contains less nutrients than regular soil.shredded bark, sawdust or even gravel make good mulches because they are non-decomposing and prevent weeds from growing.
One of the most important factors in the growth of arborvitae trees is the garden soil they are planted in. It must be a loose, well-draining soil that has a high organic content and hasn’t been chemically treated. You can check by digging a hole about one foot deep and seeing if you encounter any roots in the soil. If you do, this is an indication that the soil is probably toxic to plant life.
If you have no choice but to plant in this type of soil, then it is best to surround the roots with a barrier such as concrete, wood or plastic to prevent the toxic soil from poisoning the tree roots.
Arborvitae trees are also susceptible to a variety of diseases and pests so you should always check the health of a tree before you buy it.
Powdery mildew is a fungal disease that affects the leaves and is recognizable by the presence of a white powder on the surface of the leaves. This can be controlled by increasing air movement around the plants, removing and destroying infected foliage and applying fungicides.
Foliage spot is a disease that causes spots to appear on the leaves. This can be controlled by removing the infected leaves when spotted and increasing the distance between plants.
Arborvitae trees are also susceptible to insect pests such as the arborvitae beetle, the arborvitae leaf miner, arborvitae web worm and the flatid borer. You can find more information about these by visiting the US Forest Service website which has a detailed list of much more.
When it comes to choosing a plant that is suitable for your garden, there are a wide variety of options available to you. While the fickled homeowner might be satisfied with a combination of shrubs, ground covers and annuals to adorn their lawn. The more experienced gardener might look for something a little more permanent and durable which can survive through all sorts of weather conditions and changing seasons.
Arborvitae trees are a good choice because they have many features that can make them a long-lasting addition to your landscape. Different species of arborvitaes also have different shaped leaves which can add a nice touch of visual diversity to your garden.
One thing most types of arborvitae trees have in common is their glossy foliage which can look especially attractive when backlit by the sun. This is something to bear in mind if you plan to plant yours near your house as a backdrop.
Arborvitae trees are extremely hardy and can survive in almost any climate. They are tolerant of both shallow and deep soil, wet and dry conditions and are even fire retardant. This makes them a great choice for an inexperienced gardener who might not know exactly what sort of conditions a particular plant needs to thrive.
The main disadvantage of arborvitae trees is that they tend to grow very slowly. It can take several years before they reach a decent size and you will need to prune them regularly to prevent them from getting out of control.
If you don’t have the time to care for a large arborvitae tree and you are looking for something that is going to add instant height and elegance to your garden, then you might want to consider an evergreen shrub such as the holly shrub.
Hollies are tough plants with glossy leaves that can survive in wet or dry soil. They can grow up to four feet high and wide and are available in an assortment of different leaf colors. This makes them great for creating privacy screens, backdrops or hedges.
Unlike arborvitae trees, hollies grow quite quickly and can reach their full height in as little as three years. This means they need less maintenance than a large arborvitae tree. The only thing you have to do is trim off the occasional dead branch or undesired growth and they will remain perfectly formed.
Hollies also have the added advantage of being deciduous plants. This means that for half of the year (typically the summer months) they display a lush, dense canopy of leaves which look attractive in and of themselves. During the winter months (or any other time when they are needed) you can prune them back and they will not display any foliage at all. This means you can effectively use them as a backdrop or screen during these times and then have them disappear altogether when they are not needed.
Overall, hollies make an excellent choice for the fickle homeowner who wants something that looks nice most of the year round but doesn’t require much work to keep it that way. They can also be easily trimmed and pruned into any shape or form you desire whether it is as a hedge, backdrop, screen or any other sort of decorative feature.
If you want a tree that retains its leaves throughout the year then you are going to have to choose one of the handful that are deciduous. The most common type of deciduous tree is one that loses its leaves in the winter months and gains them back in the spring.
One of the most popular types of deciduous tree is the oak tree. During the spring, oaks put on a spectacular show with their large feathery leaves that turn a brilliant golden-yellow before falling to the ground in the fall.
Deciduous trees differ from evergreens in that they typically grow much faster and require more maintenance. For this reason, they are not a good choice for those who lack the time, energy or knowledge to care for them properly.
Deciduous trees do have one major advantage over evergreens and that is their ability to provide shelter and protection during the winter months. While you may not think so, being exposed to the elements can be very harmful and even fatal to some plants. Deciduous trees prevent this by providing a barrier (and a little extra insulation) against the cold.
If you want a tree that is going to provide the most protection from the cold and snow, then few can compare to the popular American Elm. American Elms are easy to recognize due to their distinct weeping branch pattern and rugged looks.
During the spring and summer months the American Elm is typically covered with large leaves that range in color from bright green to a dull yellow. As autumn approaches, these leaves turn an outstanding gold color before falling off altogether.
Elms can grow to be very large trees and can live for several hundred years. Unfortunately they are susceptible to disease and infestation which has limited their lifespan in many areas.
The American Beech is another popular species of deciduous tree with a reddish-brown bark that is covered with small horizontal ridges. Beech trees typically have a rounded crown and smooth leaves that are gray-green in color.
The Beech tree is very hardy and can tolerate harsh weather conditions such as drought and even severe frost. In the fall, beech trees change color starting at the top and working its way down until it is completely red, brown or yellow.
Beech trees are prized by woodworkers for their fine straight grain and ease of working. During the winter, the wood can absorb water and swell to twice its size. However during the summer it can dry out just as much without decaying.
Beeches are not very tall but can grow quite wide which limits their usefulness for timber. They are best known for their woodwork such as furniture, clocks and other items that are intended to stay indoors.
Another popular species is the yellow birch. As its name suggests, the leaves of this tree turn a bright yellow in the fall before falling to the ground.
The leaves of the paper birch are more commonly used however. The paper-thin layers of bark that grow and then roll back in a spiral pattern as the tree grows, are gently peeled off and pounded into a soft white pulp. This is then placed between two layers of cloth and pumped with water to create a thin sheet of paper.
These trees are easy to identify due to their unique cherry-like fruit that grows directly off the branches rather than from a stalk like in most other trees. The fruit of the Pin Cherry is edible and can be dried for later use.
Pine trees are also deciduous but typically only in areas with harsh cold weather. In warmer locations these trees will maintain a green foliage all year round.
Pines typically grow very straight and tall. They have long dark green needles that grow in clusters from the branches. These trees are sometimes used for lumber but their wood is typically not as strong or durable enough to make furniture.
Pine trees are most commonly recognized for their timber that is used to create the string in musical instruments such as pianos and violins.
Pitch Pine is a species that is native to North America. It has a thick red bark and grows prickly spikes along its branches. Its wood is very hard and dense making it ideal for burning as a fuel source.
Another common species is the Short-leaf Pine. These trees are typically smaller than others in the same genus but their wood is still very durable. It can be burned as a source of heat and is also suitable for constructing things like wooden tools.
The wood of the Loblolly pine is very soft and brittle making it useless for most construction purposes, however its resin is a good source of turpentine which is useful in the production of varnish for wood.
The White Pine has soft flexible needles that remain green all year round and can grow to enormous sizes. It tends to be less suitable for construction purposes but its large size means that it is still commonly used by logging companies.
The Red Pine grows in wet or marshy areas and has a reddish tint to its needles that give it its name. Its wood is not very durable and is mostly used for burning.
The Shortleaf Pine grows in dry soil and has shorter needles than other pines. Its wood is the most durable after the Loblolly pine making it more suitable for construction purposes but still less so than the harder woods of the Eucalyptus genus.
Spruce trees are most commonly recognized for their long dark green needles that grow in clusters from the branches. These trees are sometimes used for Christmas trees as their soft needles do not shed and become messy.
The wood of the Spruce tree is flexible but very strong making it suitable for constructing most things from small wooden tools to sailing ships.
Another genus of tree that grows in wet soil is the Willow tree. They tend to have long thin leaves with a pointed tip. In many species the leaves will fold up in the summer and open up when it rains providing a natural mechanism for water collection.
These trees are sometimes used by humans for weaving into baskets due to their flexibility and strength even when wet. Their wood is not suitable for most construction purposes but can be used for things like shuttles for weaving clothing. The wood from these trees is also not very good for burning as a fuel source.
There are a few rare species on the planet that have been classified as endangered. The Skypod tree is one of these rare trees. It has an unusual seeds that grows in a pod attached to a separte stalk that rises many feet into the air before releasing the seed pod. These trees grow very slowly and their wood is very hard and resistant to rot, making it an excellent choice for boat hulls, especially given that it is naturally resistant to damage by insects and water.
Unfortunately the tree grows very slowly, meaning that it takes many decades for a tree to grow from seed to maturity. The other issue is that the tree has a very narrow growing zone and can only thrive in a few specific climate zones across the planet. After the tree has been cut down, the stump usually dies making replanting impossible.
Due to these factors, the trees are not usually harvested and left to grow naturally, however when they were used in the past, every single part of the tree was used. The seed pods have been known to be carved up into jewelry by tribes that have a lot of free time.
“Conifer” is a term given to trees with needle like leaves. There are a few different types of these trees on the planet but most of them fall into a few distinct families.
The first are the Pine family, which are deciduous conifers that have short stiff needles that come in clusters of two to five from which pine cones develop further down the stem. The wood from these trees is flexible but has a tendency to warp and split, making it less suitable for constructions purposes. It’s still used by some for ship building due to the abundance of pine trees on the planet.
The other conifer family is the Fir family which are also deciduous conifers. The needles grow individually and are softer than those of the pines but also tend to be shorter. The wood is flexible like that of the pines but is less prone to splitting. It’s not as strong as pine but is more commonly used for things like building construction.
The wood from these trees is often used for furniture and flooring.
The other families of conifers are the Long Life family and the Oak Family. The Long Life family deciduous conifers have very long needles and grow very slowly. The wood is very strong but also very heavy. The leaves of these trees tend to be small and grow in clusters of seven, which is thought to be due to the fact that the sun has seven planets, maybe it helps the tree grow better with more sunlight!
The Oak family are evergreen conifers and have flat broad leaves, usually between two and six inches across. These trees tend to grow the fastest of all the conifer families and consequently have the shortest lifespan. The wood is soft and weak and not used for much.
There are many types of trees on the planet but these are some of the more common ones found in most places, especially away from the coasts.
These trees have broad leaves that can grow over a meter in width and are often several meters long as well. The trees themselves usually only grow to six or seven meters tall and wide but they tend to grow in thick groves that block out a lot of light, making them quite common in many forests.
The wood from these trees is very hard and difficult to shape, however it is very strong and unlikely to break making it excellent for things like weapons, tool handles and other places where strength is important. Due to the thickness of the wood it cannot be carved into fine objects like statues or furniture. Addax trees are most often used by the elves of Arat but occasionally they are exported to other parts of the world.
Black Ironwood Trees
These trees grow leaves that are almost black in colour, hence the name. The wood itself is jet black and only grows as large as an average tree but it grows very thick and strong. The elves of Arat are probably the only people who would bother to trade for this wood as it is so hard they are the only race that can successfully carve it into things like statues and furniture.
The leaves of the trees usually turn a deep red in the fall before falling off and new leaves grow again in the spring.
These trees grow a long spike from their trunks that are hollow and as sharp as knife. They must be handled very carefully as the slightest touch can cut you.
The wood from these trees is very hard and takes a pretty grain, it is also light in colour. The elves of Arat often use this wood for carving artwork and furniture as it is easy to work with. It is fairly rare and only grows in small groups away from any other types of trees. Because of this they are sometimes considered as anachronisms in an already old world.
Elvenwood trees are very tall and slender with leaves like blades of grass. The wood is golden in colour and glows softly in the sun. It cannot be worked by any tool or machine and can only be shaped by magic, this causes the wood to retain its smooth curves and rounded corners even after decades of heavy usage.
