Eucalyptus is a fast-growing plant that thrives both in gardens and as a houseplant. Proper pruning is essential for maintaining its shape and promoting healthy growth. Here’s how and when to prune your eucalyptus.
When is the Best Time to Prune?
The ideal time to prune eucalyptus is in early spring, especially in March, before the plant begins to sprout again. During this time, eucalyptus recovers from pruning most effectively, and any frost damage can also be removed in one go. Summer and autumn pruning are less recommended, as the plant is more susceptible to stress during these seasons and growth could be hindered.
How to Prune Eucalyptus?
Eucalyptus is quite resilient to pruning and can handle larger cuts without issue. It is important not to damage the roots, and the best tool for the job is a sharp pruning shear.
Step-by-Step:
- Remove Dead and Diseased Wood: For outdoor plants, cut back long, dead, or diseased branches, as well as any crooked or disruptive growth.
- Prune Indoor Plants More Severely: If your eucalyptus is getting too large or not growing densely enough, cut back about a third of the length of the branches. A more severe pruning encourages new growth and a compact form.
- Remove Dried or Wilted Parts: If there is water stress or damage from other care mistakes, cut back the dried parts of the plant to encourage fresh, healthy growth.
Shaping Eucalyptus
Depending on your desired outcome, eucalyptus can be pruned to grow as either a tree or a shrub.
Pruning Eucalyptus as a Tree
- Remove the Bottom Third: Cut back the lower branches to expose the trunk.
- Light Pruning on Top: Only lightly prune the upper branches to promote outward growth.
- Wind Protection: Eucalyptus trees are sensitive to wind, so using a stake to support the tree is recommended to keep it upright.
Pruning Eucalyptus as a Shrub
- First Cut in Year 1: Prune the main stem back severely, just a few centimeters above the ground, to encourage branching.
- Subsequent Cuts: After the first year, choose the strongest new shoots and cut back the rest to maintain a bushier appearance.
- Regular Maintenance: In the following years, continue removing unwanted side shoots to promote dense, healthy growth. It’s also a good idea to feed the plant with a complete fertilizer during its growing phase.
Tip for Using Pruned Materials
The cuttings can be put to good use. Eucalyptus branches make excellent decorations or can be used to brew tea. The leaves and twigs have a pleasant fragrance and a calming effect.
Eucalyptus is an easy-to-care-for plant that can be shaped and pruned to suit your preferences. Regular pruning not only keeps the plant looking great but also supports healthy growth. Whether as a shrub or tree, with the right pruning methods, your eucalyptus will remain lush and attractive.
