Aluminum plants are very popular among hobbyists because they have a long growing season, require little water and fertilizer, are easy to grow indoors and outdoors, are drought tolerant and do not need any special lighting or ventilation. They also produce their own oxygen. These qualities make them ideal indoor houseplants.
The most common problems with aluminum plants are:
Leaf tips turn brown when exposed to sunlight.
These brown tips may appear at any time during the day but usually occur between mid afternoon and night. They will disappear after sunset.
They may become darker if there is too much light or too little shade in your home.
If these brown tips persist, it means that your plants have been damaged by lack of air circulation in the room where you keep them.
Aluminum plants can be grown indoors or out. Alumina (the metal) is toxic to humans and animals so it must be kept away from living creatures! Aluminum plants cannot tolerate high levels of humidity in either case.
To prevent aluminum plant browning, you should keep the soil moist all year round. Keep the soil evenly moist even when watering aluminum plants. Never allow the soil to dry out completely.
Keep your plants in small containers (pots) which have good drainage.
The most common problem with aluminum plants is not enough light. To guarantee strong and healthy growth, place them in a bright location out of direct sunlight. If this doesn’t work then you can grow them under fluorescent lights.
Place the pots of aluminum plants on trays filled with pebbles and water to maintain high humidity around the plants at all times. Growing aluminum plants outside in the yard is not a good idea. If you want to grow them outdoors, keep them in a shady area.
You should never allow leaves of your plants to touch each other as it will cause them to stop growing and may even cause them to turn yellow and fall off. Watch out for chewed leaves – they are often the result of hungry spider mites. They can also be damaged by cold draft blowing directly on the plant.
The soil must contain the right mixture of nutrients in order to keep your plants healthy. You should use a mixture that contains peat moss, sand, loam, and/or vermiculite. Particle size should be small.
The best solution is a mixture of equal parts peat and sand or perlite.
Great care must be taken when watering aluminum plants. It is easy to over water these plants. Rots usually starts in the roots and may not be visible above ground.
The first sign that you will notice is the plant wilting even though you’ve watered it recently. Brown leaf tips are also a sign of underwatering.
Add a thin layer of small gravel at the bottom of each pot. This will help with drainage. Before watering, let the soil dry out a bit.
Aluminum plants need to be watered thoroughly but then should be left alone to allow the soil to dry out completely. Overwatering is the main reason for aluminum plants to wilt and develop root problems.
Almost all problems with aluminum plants can be prevented by allowing the soil to dry out between waterings. If you have healthy plants that are not wilting, not losing leaves, and are growing well, they probably don’t need water.
Provide sturdy supports for plants that are growing in pots. If plants are not staked or caged, they will often fall over because the thin stems cannot support the weight of the plant.
It is easy to propagate aluminum plants from leaf cuttings. Simply take a leaf cutting and place it into a cup of water. Let the cutting sit in the water until you see little roots start to develop from the bottom of the cutting.
Once this happens, the cutting can be placed into a pot filled with cactus potting soil and potted.
Test your soil to make sure that the pH level is around 6.5. Aluminum plant grow best in slightly acid soil (weaker acids).
Soils that have a higher pH than 6.5 tend to have aluminum in them. Alkaline (stronger) acids can harm or even kill aluminum plants. Use either ericaceous soil (containing ericaceous compost) or add lime to your normal soil mixture to raise the pH level.
Aluminum plants are used for a variety of purposes including topiaries, hedges, and screens. They can also be trimmed into spheres, cubes, and other geometric shapes. There are also specialized aluminum plant pots that can help create interesting landscape designs.
Aluminum (pronounced /æljʊˈmeɪnəm/) is a chemical element with symbol Al and atomic number 13. It is a silvery-white, soft, nonmagnetic, ductile metal. Aluminium is the most abundant metal in the earth’s crust, and the third most abundant element.
It makes up about 8% of the planet’s mass and its greatest abundance on Earth is in the soil. Aluminium is remarkable for the fact that it is a very valuable metal that does not naturally occur in the free state…
Aluminium has been commercially produced since 1825. Today, the leading producers of aluminium include China, Russia, United States, Canada, Brazil and Australia. In 2010, the global production of aluminium was around 31 million tonnes annually.
Aluminium is commonly used in aircraft, cars, offices, homes, foil and window frames. It is also used in the manufacture of screws, kitchen utensils, spark plugs, and batteries…
The metal was first isolated by Hans Christian Oersted in 1825. Aluminium is a common and widely occurring element found in large quantities in the Earth’s crust. Aluminium is the third most abundant element in the Earth’s crust (about 8%), after oxygen and silicon…
The name of the element comes from the Latin word alumen (alum) which in turn comes from the Arabic name for the ancient Egyptian city of Al-Jīz (الجيز), originally named Thonis. Thonis is an older English name for the same ancient city…
Aluminium was called various names before “aluminum” eventually became the accepted name. The element was called ” alumium,” “aluminum,” and also “aluminium” (the first two of which are still accepted as valid chemical names for the element). Russian chemist Dmitri Mendeleev claimed that aluminium had been originally called “aluminium”, and wrote to the International Union of Chemistry proposing that the new name of the element should be “aluminium”, rather than ” aluminum.” His suggestion was accepted on November 12, 1887.
Alium is the Latin word for “garlic.” It is also the name of a Roman Consular Road that ran from Rome to Lanuvium. This road was built by Appius Claudius Caecus who also built the Appian Way.
The road started at Porta di San Paolo and passed through Terracina and Pontina before ending at its destination…
The name Alium was used by the Romans to refer to Garlic.
Alium is also a genus of plants native to Australia, Africa and South America. They are said to be closely related to Tulips.
Alium cernuum (Nodding Onion), the type species of the plant genus, is the most popular species in cultivation. It is sometimes grown for its interesting flowers.
The common name “nodding onion” or ” nodding wild onion” refers to severalspecies of plants in the genus Allium which have a basal rosette of leaves and a long scape (spike) bearing an umbel of flowers. The scape is articulated so that it nods forward. Allium vineale, the clustered nodding onion, has a dense spherical cluster of narrow strap-shaped leaves and is found on dry limestone grassland…
The nodding Allium is the emblem of the Isle of Man and appears on the national flag.
There are many garden plants and flowers that are also called Allium, including:
* Ornamental onion or Ornamental garlic (A.undecompositum), from Southwestern United States.
* Ornamental onion (A.cornebianquum), from the Caucasus.
* Ornamental garlic (A. neapolitanum, A. Warscewiczii, A.
Porrum, and A. Roseum), from Europe and North America
Also called “poor man’s asparagus.” Mature plants can reach 2 meters (6 feet) tall. The spherical seed heads are made up of small umbels, which resemble bunches of black berries.
Also known as the “nodding onion,” Allium cernuum is native to most regions of the United States and is typically found in damp fields, meadows, thickets, and shady woods.
The Allium Alliance (Allium spp) originates from Mexico. It is a short-lived perennial which is typically grown as an annual vegetable crop. Edible parts include the entire plant (bulb, stems, leaves).
The nodding wild onion (A. cernuum) is a small, stout plant with a coat of glossy, hair-like fibers and nodding, bell-shaped purple flowers. The bristly bulb of the nodding wild onion may be eaten cooked or raw when it has a mild flavor somewhat like that of a leek.
It may also be used as a flavoring in soups and sauces. The nodding wild onion grows in moist or wet woods from Connecticut to Michigan south to Tennessee and Arkansas.
The prairie onion (A. stellatum) is a small, tufted plant with a cluster of star-shaped yellow flowers and taste somewhat like a leek. The prairie onion is found from Kansas to Texas and eastward to Missouri and Illinois.
The woods onion (A. canadense) has a cluster of greenish-white flowers and a strong taste. It is found in dry, open woods from Pennsylvania to Ontario and south to Georgia and Texas.
Allium vineale, the yellow nodding wild onion, is a very small plant with a coat of yellow hairs and nodding, bell-shaped yellow flowers. The very small bulb is edible and has a mild taste preferred with butter or in salads. It is found throughout most of the United States.
Allium vineale (Nodding Wild Onion)
Origin: North America
Region: Eastern and Central United States
Edible Parts: Bulb, leaves, flowers
Flavor: Pungent, garlicky taste strong, but mellow when cooked
Size: 6-20 inches tall, 0.5 inch bulb
Other: The entire plant is edible.
About Allium Vineale:
Also known as Nodding Wild Onion, Wild Onion, or Prairie Onion, A. vineale looks very much like the larger garden onion on a very small scale. It has a strong smell and taste that gets more intense when the plant matures.
The entire plant can be eaten raw or cooked. The plant itself is very small, with a neat, spherical cluster of green leaves, and a bulblet that nods (hence the name).
In some areas this plant is considered weedy or even invasive. It is now listed as a noxious weed in several states. However, the plant is edible and the bulb can be used like any other onion or leek.
It grows in open, sunny areas like meadows or even roadside verges. It has a short stem and bright green leaves in a neat cluster, with a single bulblet or onion that sits at the bottom of the cluster.
When Allium vineale is very young it can be confused with other plants which have a similar profile, but have very different leaves:
Nodding Pink Onion (A. cernuum) has pink flowers and nodding, bell-shaped flowers. It is found in wet, open places from Texas to South Carolina.
Creeping Shortia (A. stellatum) grows in dry woods and rocks. It is found in dry, rocky woods from Pennsylvania to Illinois and south to Georgia and Alabama.
It has bright yellow flowers and the bulblet sits above the leaves rather than at the bottom of the cluster.
