Eucalyptus seedlings are very easy to propagate when they’re planted in soil. You need just one thing – some good quality soil! If you have a small patch of land where you want to plant your own eucalyptus plants, then it’s time to get started with planting your first tree or shrub. There are many different varieties of eucalyptus trees and shrubs available for sale at garden centers and nurseries. They range from the most common eucalyptus (e.g., Eriogonum vulgare) to rarer species such as the Australian native ‘Blue Gum’ (Eucalyptus grandis).
The variety of eucalyptus tree or shrub you choose will depend upon several factors including its size, shape, and whether it needs support during its growing season. For example, if you want to start a small tree in your backyard, then a smaller variety of eucalyptus might be suitable. However, if you want to grow a large tree on your property, then it would make sense to try out larger varieties.
You’ll also need to consider what kind of soil you have available. Some types of soil are better than others for certain kinds of plants. For example, eucalyptus trees need well-drained soil to grow and flourish.
If you have heavy, wet soil, then it might be necessary to improve your soil before planting a eucalyptus tree or shrub.
Does your soil contain high levels of clay?
If so, then your soil is considered to be ‘heavy’ and will need improving before planting. You can do this by adding some organic matter, such as rotted leaves or mulch, to the top layer of soil.
Alternatively, does your soil contain high levels of sand?
In this case, you’ll need to add some organic matter to improve its texture and make it lighter and easier for your eucalyptus tree or shrub to grow.
Once you’ve added the right kind of organic matter, your soil is ready for planting. Most garden centers and nurseries will be able to tell you exactly what kind of soil your eucalyptus tree needs to grow and the best way to prepare it.
How To Start Propagating Eucalyptus From Cuttings
The first step in how to start propagating eucalyptus from cuttings is to find a suitable cutting. This may sound obvious, but you’ll need to find a cutting that is young and fresh. Look for cuttings that are taken from the current season’s growth.
Also, make sure your cutting contains some leaves as well as at least one bud. Cuttings that are taken from healthy, young trees are the most likely to take when you start propagating eucalyptus from cuttings.
Once you’ve found a suitable cutting, it’s time to prepare your cutting container and potting mix. Eucalyptus cuttings can be sensitive to being overwatered. For this reason, it’s best to use a very porous soil when starting eucalyptus from cuttings.
A well-draining medium such as perlite or pine bark works best. Fill your container with your soil of choice and make a small pit in the middle. This pit should be deep enough to hold plenty of water and nutrients for your cutting but not so big that water gathers and becomes stagnant.
After preparing the container, take your cutting and make a small diagonal cut at the base of the stem. This will encourage the stem to ‘root’ into the potting mix. After making the cut, place the cutting in the prepared container and gently firm down the soil around it.
You probably want to place a label on the container so that you can identify it once it has rooted. Also, make sure the cutting is secure and won’t fall over or be knocked out of the pot by mistake!
Finally, it’s time to water your cutting. You may need to water it more than once to ensure that all the cutting’s soil is properly moistened. It’s best to water from above, either with a watering can or a cup.
Once you’ve watered your cutting, you’ll need to place it in the location you picked out for your eucalyptus tree or shrub to grow. The best place is one that is exposed to sunlight throughout the day. If this isn’t possible, make sure you place your container somewhere that it will receive several hours of sunlight each day.
You’ll also need to make sure the cutting is protected from strong winds and harsh frosts. If the cutting’s leaves begin to turn brown and crisp, the cutting is probably receiving too much cold or wind. If this happens, find a new location for your container or move it indoors until autumn.
It will take several weeks for your cutting to start showing signs of rooting depending on the species of eucalyptus you’re propagating. Often, the cutting will start to put out a tiny green shoot at the base of the stem. When this happens, you’ll need to move your container into a sheltered, partially shaded area.
This will be the beginning of your eucalyptus tree or shrub! Soon it will develop its own roots and won’t need to be in a container any longer.
When your cutting has developed several sets of leaves, it’s time to transplant it into the ground. Carefully dig a small hole for it, firming the soil around its roots as you do so. Make sure there are no other plants or weeds competing for nutrients and space and be careful not to damage the new roots.
Now is also a good time to give your tree some fertilizer. Eucalyptus grow very quickly and will use up nutrients at an astonishing rate. Make sure to feed your plant with a high quality fertilizer several times through the growing season.
This will ensure that it continues to grow at a good rate.
You’ll want to keep an eye on your plant’s water needs as well. Eucalyptus can survive in arid conditions but will grow much healthier and more quickly if they have access to water. If the weather is abnormally dry, you may need to give your tree a little extra water.
Care for your plant throughout the year and it should continue to grow. Eucalyptus make excellent additions to any garden or farm due to their rapid growth and ability to thrive in adverse conditions.
These plants can also be sold for profit or you can continue to care for them yourself. If you want to keep the tree yourself, make sure to give it the room it needs to grow into the giant that it’s capable of becoming!
