Should I Trim My Indoor Olive Tree? 

Should I Trim My Olive Tree

It’s a good practice to trim your indoor olive tree for many reasons. Removing dead or diseased branches, for instance is vital for your tree’s overall health and aesthetic appearance. When you trim its suckers and branches growing inward, this promotes better air circulation and allows more light to penetrate. 

Pruning also maintains the tree’s shape and size, and prevents overcrowding, which can lead to disease or pest issues. Additionally, regular trimming can enhance fruiting and new growth.

Signs Your Olive Tree in a Pot Needs Pruning

Your olive tree may need pruning if it starts showing the following signs: 

  • It’s too big or bushy 
  • Sparse-looking and leggy appearance
  • Dead, diseased, and damaged branches
  • Crowded branches
  • Stunted or no new growth
  • Poor fruit production

So, if you notice any of these issues with your potted olive tree, trimming the problematic branches will improve its look and overall health.

When Should Olive Trees Be Pruned?  

The best time to prune olive trees is late spring or early summer, ideally before new fruits emerge. This also happens to be their inactive period, allowing sufficient time for optimal healing and minimal stress. Pruning in late spring or early summer also means that you’ll avoid extreme temperatures, heat waves or frost. 

Pruning an Olive Tree: Tools & Supplies 

You’ll require the following tools and supplies to prune an olive tree: 

  • Sharp, sterilized pruning shears
  • Gardening gloves
  • Wound dressing
  • Ethanol or isopropyl alcohol (for tool sterilization)

Important: Clean and sterilize your pruning shears to prevent the potential spread of disease through cuts. You can use ethanol or isopropyl alcohol and a cloth to wipe your pruning tools with and eliminate any potential disease-causing pathogens.

How Do You Prune a Potted Olive Tree?

How Do You Prune an Olive Tree

Once you’ve gathered the above tools and supplies, follow these steps to prune a potted olive tree in the right manner: 

Inspect the Olive Tree

The first step involves inspecting the olive tree for any dead, diseased, or damaged shoots and branches. Identifying the areas that need attention is important to enhance the tree’s structure. 

Begin With Thinning Cuts

Using your sharp, sterilized pruning shears, cut shoots less than ¾-inch and branches 1 to 3-inch in diameter. To address crowdedness, aim to remove any inward-or downward-growing branches. This will facilitate better light penetration and and improve air circulation. 

Trim the Top Part

Next comes the top part of the central stem or excessively tall branches, which should be pruned to encourage new growth and achieve a better shape. This will also help the overall olive tree canopy appear balanced.

Create an Open Vase-Like Shape 

Give the tree the ideal shape of a vase or martini glass. Leave 3-4 strong lateral branches (at least ¾ inches thick and growing out and upward from the trunk), and cut the remaining ones. This way, the olive tree will appear wider at the top and narrow at the base, just like a vase.

Tip: You can also prune your olive tree into a globe, or bush-like shape.  

Re-Access the Tree

Re-access the olive tree to see if it needs more trimming for a more balanced look. If yes, make the final adjustments. 

Protect the Cuts

Although optional, we highly recommend applying a wound dressing to the fresh cuts to protect them from pests or diseases. 

Indoor Olive Tree: Care After Pruning

Ensure to apply the right care for your indoor olive tree, post pruning, with the following expert tips: 

  • Place your olive tree in a spot that receives bright, indirect sunlight for most parts of the day. Direct exposure to the sun can be too harsh for your freshly pruned plant. 
  • Avoid overwatering, letting at least half the soil dry out between waterings. Good drainage is a must to prevent soggy roots. 
  • Low to moderate humidity goes a long way in keeping your pruned olive tree cheerful. 
  • Give your olive tree some time to recover after trimming it and feed it with a nitrogen-rich fertilizer to boost its health.. 
  • Regularly inspect your olive tree and protect its fresh cuts from diseases and pest infestations.

Conclusion 

Indoor olive trees are low-maintenance plants that usually require pruning once a year. This task is typically done in spring or early summer once your olive tree begins to open its flower buds. Pruning frees your olive tree from dead, diseased, and damaged branches, improves sunlight exposure and air circulation. Trimming your tree into the right shape also makes it more aesthetically appealing.  Last but not least, it leads to more vigorous growth, potentially increasing fruit production.

Pairing the right companion plants with your olive tree can further enhance the aesthetics of your indoor greenery. Unsure which indoor plants to choose? Consider bringing home the decorative dwarf olive tree, some aromatic herbs, or flowering plants like jasmine, oleander (which has similar foliage like the olive tree), or eucalyptus for a thriving indoor garden.
