I totally understand how frustrating it is for you. I’ve had to deal with curling leaves on plum trees for years. It’s really annoying when those pretty plum leaves start to twist up like they’re doing some weird yoga pose. But don’t worry, I’ll tell you everything you need to know about this annoying issue.
What’s Making Your Plum Leaves Curl?
Here’s the deal – if you’re seeing curled up leaves on your plum tree, you’re probably dealing with leaf curl plum aphids (Brachycaudus helichrysi). These tiny troublemakers are usually:
- Shiny little bugs
- Yellowish-green to brownish-yellow in color
- Hanging out mostly on new shoots
- Creating a sticky substance called honeydew
How to Tell If You’ve Got an Aphid Problem
Trust me, these signs are pretty easy to spot:
- Tightly curled, deformed leaves (especially at branch tips)
- Sticky honeydew residue on leaves
- Black sooty mold growing on the honeydew
- Ants marching up and down your tree (they love that honeydew!)
- Reduced tree growth
- Smaller fruit with less sugar content
The Aphid Life Cycle (Know Your Enemy!)
These little pests are pretty sneaky with their yearly routine
- Fall: They come back to plum trees to lay eggs
- Winter: Eggs chill out near the leaf buds
- Spring: Eggs hatch right when buds break
- May: They peace out to other plants (usually daisies)
How to Fix Curling Leaves on Your Plum Tree
Natural Solutions (My Favorites!)
-
Water Blast Treatment
- Grab your hose
- Give affected areas a strong spray
- Do this early before leaves curl too much
- Repeat as needed
-
Invite the Good Bugs
- Lady beetles
- Green lacewings
- Brown lacewings
- Soldier beetles
- Syrphid fly larvae
Chemical Solutions (When You Need the Big Guns)
During Dormant Season:
- Use horticultural oil
- Apply in early November
- Follow up with monitoring
During Growing Season:
- Neem oil
- Pyrethrins
- Insecticidal soap
- Alternate between treatments to prevent resistance
Prevention Tips (Cause Who Wants This Problem Again?)
-
Watch the Fertilizer
- Cut back on nitrogen
- Less new growth = less aphid food
- Focus on balanced nutrition
-
Regular Monitoring
- Check new growth often
- Look under leaves
- Catch problems early
-
Proper Timing
- Mark your calendar for November treatments
- Be ready with controls in early spring
- Don’t waste time with late summer treatments
Important Things to Remember
Listen up, these are super important points I’ve learned the hard way:
- Once leaves curl, they STAY curled (even after aphids are gone)
- Fungal sprays won’t help (this ain’t peach leaf curl!)
- Late summer treatments are useless (aphids are already gone)
- Natural predators are your friends (encourage them!)
My Personal Tips
I’ve dealt with this problem tons of times, and here’s what I’ve learned:
- Don’t panic when you see curled leaves
- Focus on prevention for next season
- Keep your tree healthy with proper water and nutrients
- Consider removing nearby daisy family plants
- Mark your calendar for fall treatments
When to Call the Pros
Sometimes you gotta wave the white flag. Consider getting help if:
- The infestation is massive
- Your tree shows severe stress
- Multiple treatments haven’t worked
- You’re unsure about proper chemical applications
Remember that dealing with plum tree leaves that curl isn’t fun, but it can be done if you know what to do. Just make sure you keep up with your treatments and watch out for those early warning signs!

Leaf Curl Plum Aphid
Aphids on plum trees that are found inside curled leaves are leaf curl plum aphids. The pests are tiny and have shiny bodies that range from pale green to light yellow in color. The insect produces a high volume of honeydew, which is the excretion of the aphid. In turn, this brings in ants that eat the sweet liquid and makes a fungus that makes sooty mold. Plum aphids cause leaves to curl as they suck the trees fluids. In the winter, aphid eggs stay on plum and prune trees. As adults, they may move to other plants to lay their eggs. Leaf curl plum aphid treatments may help minimize fruit loss and increase plant vigor if the pest is properly identified and treatments begin at the correct time.
Aphids on Plum Trees
Damage to fruit trees by these aphids starts with the feeding on young terminal shoots. This can affect the growth of the tree and reduce the foliar canopy as the new leaves curl and die. It is important to control plum aphids, as populations can quickly get out of hand and serious infestations drain plant reserves. The aphids hatch just at bud break on the tree and begin feeding immediately on shoots and then on the underside of leaves. The curled leaves create a shelter for the pests. If you look at the shoots early on, you can tell if you have leaf curl plum aphids and improve your chances of getting rid of the bugs.
