Pruning
When olive tree suckers take over your tree’s trunk and branches, they’re stealing energy from the fruit and foliage you actually want. ✂️ I’ve seen healthy olive trees turn into tangled messes when suckers go unchecked—until I learned the late-winter pruning trick that clears them out while boosting next year’s harvest.
The secret lies in timing and technique: prune right after dormancy but before new growth starts, using sharp bypass pruners to cut flush with the trunk. You’ll need gloves, a sanitizer spray, and a clear day to avoid stressing the tree.
Most suckers are just water sprouts, but a few might be root suckers—those need extra care to prevent disease.
After trimming, your olive tree will redirect energy into stronger branches and bigger fruit. The first year, you might see a 20% increase in production, and the tree’s shape will open up to sunlight. Just avoid over-pruning—never remove more than 25% of the canopy at once.
Here’s the bonus: those suckers can be propagated into new trees if you’re patient. Dip the cuttings in rooting hormone and keep them moist until they establish.
For long-term care, mulch around the base and water deeply once a week—this keeps the tree focused on growth, not fighting off unwanted shoots.

Step-by-Step guide to removing olive tree suckers
Here's how to tackle those unwanted shoots for a healthier, more productive tree.
🌱 Step 1: Identify Suckers and Gather Tools
Suckers are the fast-growing, vertical shoots that sprout from the base or branches of your olive tree. They steal energy from your main tree, so removing them early prevents stress. Grab your pruning shears and sharp bypass pruners—dull blades tear bark and invite disease. I always clean my tools with 70% rubbing alcohol before starting to keep cuts sterile.
Look for suckers that grow straight up from the ground or branch junctions. They often have a thinner stem than your main branches. This is the moment that matters: catching suckers early means less work later and a stronger tree structure. If you're unsure, compare the sucker's stem thickness to a pencil—if it's thinner, it's likely a sucker.
✂️ Step 2: Cut Suckers at the Right Angle
Make your cuts just above a bud or branch collar—the swollen area where the sucker meets the main branch or trunk. Cutting too close leaves a stub that can rot, while cutting too far back removes healthy growth. Angle your cut slightly away from the branch collar so water runs off, preventing rot.
For suckers at the base of the tree, cut them off at the soil line. If you leave any stem below ground, it'll regrow. I like to make a clean cut with one swift motion—no sawing back and forth. This ensures a smooth wound that heals faster. Real talk: if you're hesitant to cut, wait until the tree is dormant in late winter, when it's less stressed.
🌿 Step 3: Monitor for Regrowth and Repeat
Suckers are persistent, so check your tree every 2-3 weeks in late winter and early spring. New shoots will pop up, especially if the tree is young or stressed. The goal is to remove them before they grow more than 6 inches tall—that's when they start competing for nutrients.
Here's the thing—if you see suckers sprouting from the same spot repeatedly, it might be a sign of root suckers. In that case, dig around the base carefully with a hand trowel to expose and trim the root itself. Just be gentle; olive trees have shallow roots. You'll know you're doing it right when the regrowth slows after a few rounds of pruning.
☀️ Step 4: Fertilize and Water for Recovery
After removing suckers, give your olive tree a boost with balanced fertilizer (10-10-10 ratio) to help it recover. Spread the fertilizer evenly around the drip line—about 2-3 feet from the trunk—and water it in deeply. This encourages strong root and branch growth, so your tree puts energy where you want it.
Water the tree 1-2 times per week until new growth appears, keeping the soil moist but not soggy. Olive trees are drought-tolerant, but they'll appreciate the extra care after pruning. You'll see new leaves emerge within 4-6 weeks—that's your signal everything is working. If a branch looks wilted or yellow, it might need more water or a closer look for disease.
Tips & tricks for perfect olive tree pruning
Late-winter pruning transforms your olive tree—here's how to avoid common pitfalls and get it right the first time.
Tool Prep is Everything: I can't stress this enough—sterilizing your pruning shears and bypass pruners with 70% rubbing alcohol before you start prevents disease transmission. This is especially important if you're working with multiple trees or have had issues with fungal infections in the past. I keep a small spray bottle of the alcohol handy for quick cleanups between cuts.
Visual Cue for Perfect Cuts: In Step 2, when making those critical cuts just above the bud or branch collar, think of the "45-degree rule": angle your cut slightly away from the collar so water runs off. This prevents rot that can kill your tree. For stubborn suckers, I use a small piece of masking tape marked with a line at the right angle—it's a game-changer for consistency.
Root Sucker Rescue Strategy: If you're dealing with persistent root suckers (mentioned in Step 3), here's my secret: after exposing the root with your hand trowel, make a clean cut with your pruners, then apply a thin layer of pruning sealant to the wound. This optional step (I mark it clearly) helps prevent disease entry points while the tree heals. The key is to work when the tree is dormant—late winter is perfect timing.
Fertilizer Application Tip: When applying that 10-10-10 balanced fertilizer in Step 4, I recommend creating small trenches about 2 inches deep around the drip line. This helps the fertilizer reach those shallow roots while preventing runoff. Water immediately after application to activate the nutrients—this is when your tree will really appreciate the extra care during its recovery phase.

Frequently asked questions
Got questions about tackling olive tree suckers?
You’re not alone! Here are answers to the most common concerns—so you can trim with confidence and keep your tree thriving.
When is the best time to remove olive tree suckers?
Late winter (just before new growth starts, ideally in February or March) is ideal. This timing minimizes stress on the tree and prevents pests from hiding in fresh cuts. Avoid pruning in fall or early spring—it can encourage disease or attract unwanted critters.
How do I tell the difference between suckers and healthy branches?
Suckers grow vertically from the base or trunk, often thinner and leafier than mature branches. Healthy branches usually spread outward at an angle and have woody stems. If in doubt, snap a small twig—suckers are green and flexible; mature wood is brown and rigid.
Can I prune suckers anytime of year, or does timing matter?
While you can remove suckers year-round, late winter is critical for long-term tree health. Pruning in summer or fall risks stressing the tree or inviting fungal infections. If you spot aggressive suckers mid-season, sterilize tools with rubbing alcohol and cut just above a leaf node to encourage healing.
What if I cut a sucker too close to the trunk—will it regrow?
No worries! Olive trees are resilient. If you accidentally cut too close, the tree will seal the wound naturally within a few weeks. For stubborn regrowth, apply a pruning sealant (optional) or let the tree’s own callus form. Just avoid over-pruning—never remove more than 25% of the canopy in one session.
Are there chemical alternatives to manual pruning for suckers?
While chemical treatments (like horticultural oils or growth regulators) exist, they’re not recommended for olive trees. Manual removal is the safest, most effective method. For large infestations, consult a local arborist—they can assess whether underlying stress (like poor drainage or pests) is fueling sucker growth.
What should I do if suckers keep coming back after pruning?
Persistent suckers often signal stress or imbalance. Check for:
- Overwatering (olives hate soggy roots—ensure well-draining soil).
- Nutrient deficiencies (apply balanced fertilizer in early spring).
- Competing plants (remove weeds/shrubs within 3–5 feet of the trunk).
Wrapping up and next steps
Removing olive tree suckers in late winter isn’t just about tidying up—it’s an investment in your tree’s long-term health and productivity. 🌱 By mastering the right techniques and timing, you’ll encourage stronger growth, better fruit yield, and a more resilient tree.
Now that you’re armed with the knowledge, grab your pruners and get ready to give your olive tree the care it deserves!
Next step: Schedule your late-winter pruning session (before bud break) and watch your olive tree thrive! 🌿
