What to Do With Your Cherry Trees in July – 5 Easy Ways to Enjoy Sweeter Fruits and Bumper Harvests

The prospect of sweet cherries is tantalizingly close as midsummer arrives. Cherry season usually peaks around this time, although the exact timing depends on your specific location, local weather conditions, and the type of cherry you are growing. If you’re cultivating sweet cherries like 'Bing', 'Rainier' or 'Stella' then a few timely tasks are going to influence the size, sweetness and bulk of your crop. Accomplishing these chores will have a direct impact on how sweet, juicy, and beautifully bird-free your harvest of summer cherries will be.

Fortunately, the work required for cherry tree care in July won’t break your back nor dampen your summer mood. These tasks are simple, fast, and intensely rewarding, as the payoff will be the sweetest, plumpest, and heaviest harvest of summer cherries you’ve ever had. But don’t put off these tasks: they are essential to protect and maximize the sugar and moisture content of your developing fruit.

You don’t want your precious fruits to fall foul of unexpected heat waves or sudden summer downpours. By stepping in with some simple deeds right now, you aren't just protecting this year’s bounty, either. You are also safeguarding the reserves your tree needs to return even stronger next season.

Best Cherry Care in July

Taking time for cherry care in July is a win-win for your home orchard. Whether you live in a mild coastal zone or a blazing interior valley, cherry trees are under intense pressure to support heavy fruit loads while fending off seasonal pest surges. These basic care strategies prevent fruit splitting, premature dropping, and bird raids, ensuring your harvest lasts longer and tastes vastly superior across USDA zones 4-9.

These protective measures for cherries in early summer don’t just protect your harvests, they also replenish the tree. July is a great time to boost soil moisture, light penetration, and nutrient availability, to help your tree finish fruiting without depleting energy reserves. It also helps your tree transition into setting fruit buds for next year, protecting against biennial bearing, and keeping trees vigorous and productive for decades.

Before diving into these tasks, ensure your cutting tools are sharp, clean, and sterilized to prevent the introduction of systemic disease. Before adding anything else to the soil around your tree, check moisture levels in the ground using a soil diagnostic tool. The XLUX Soil Moisture Meter from Amazon can help you to gauge soil moisture deep within the root zone before you water or add any supplements.

1. Deep, Consistent Watering

Everyone knows that cherry trees need water to grow, thrive, and produce juicy fruit. But how much and how often depends on the growth stage and the weather. Sweet cherries are preparing to fruit and trees need deep, consistent watering. Temperatures are rising as we get to July. It’s easy to overcompensate by dramatically increasing the amount of water you give the tree, or watering twice a day. But this is neither ideal for the tree nor good for your summer cherry harvest. Instead, think deep, consistent watering to stop fruit from splitting.

Deep watering a cherry tree encourages strength and resilience, by encouraging the tree’s roots to dive deeper into the soil. You can deep water with a garden hose or a soaker hose, just as well as with a complex sprinkler system. Focus water around the drip line, not near the trunk (since this can cause disease). Go for a 50ft option such as the RainPoint 50Ft Flat Soaker Hose from Amazon. Try to set up a regular irrigation schedule and stick to it. Overwatering or inconsistent watering can cause cherries to split. Bear in mind that cherry trees in containers will dry out more quickly.

Aim for one deep soaking per week that penetrates 12-18 inches (30-45cm) into the ground, rather than shallow daily sprinkles. For container-grown varieties, check pots daily, as they can dry out entirely in a single hot afternoon, arresting fruit development and turning skin bitter. Use Pro-Mix Premium Moisture Potting Soil Mix from Walmart to help regulate water retention and enhance nutrient uptake.

2. Apply a Thick Mulch

Cherry trees grow best in soil that neither gets waterlogged nor dries out for long periods. Organizing your irrigation is an important step toward making this happen for your tree, but there’s another easy way to lock moisture into the soil beneath the tree and keep that soil cool, and that’s mulching. You may have mulched your trees in early spring, but by July we need to add more. Garden compost works well for cherry trees, but any well-rotted organic matter will do just fine. Try a sprinkling of an organic compost like Charlie's Compost from Amazon to help microbial life.

A properly applied midsummer mulch layer functions as a protective shield, reducing surface evaporation by up to 70%. When applying your organic matter, layer it 3-4 inches (8-10cm) thick, extending all the way out to the tree’s drip line where the active feeder roots reside. Don’t let the mulch touch the bark, though. Keep a clear 6-inch (15cm) ring around the base of the trunk. Burying the root flare traps moisture directly against the wood, inviting collar rot, fungal cankers, and boring insects. For an extra boost to your soil, consider mixing fine wood chips with rich leaf mold to encourage beneficial mycorrhizal networks that enhance nutrient uptake.

3. Deploy Bird Netting

We love to watch garden birds on our backyard feeders, but it’s not so pleasant to watch them chowing down on our ripening cherries. But face it, birds love to eat cherries, so a polite sign is not going to help. The trick is to cover your tree with bird netting before you think you need to (in other words, before the fruit turns red). If your tree is small enough, cover the whole structure. Otherwise, cover individual branches. Keep the netting above the fruits, stretch it taut, and fasten it securely.

For whole trees, try a zip-bag such as Homada Fruit Tree Netting Cover with Drawstring from Amazon for a tangle-resistant mesh that won’t harm wildlife. For targeted cluster protection, use Agfabric Fruit Protection Bags from Home Depot. These are great for wrapping individual high-yielding branches or protecting patio cherry tree crops with ease. For container trees, consider a fruit cage or move the trees into the greenhouse until fruiting is done.

When installing protective netting, pull the netting tight over a framework (like PVC pipes or bamboo stakes) to keep the mesh suspended away from the outermost branches. If the netting rests against the fruit, clever birds will sit on top of the mesh and peck through the holes. If it is taut like a trampoline, birds will fly away safely without getting caught. Look for a mesh size of 20mm or less.

4. Tackle Aphids and Cherry Blackflies

Bugs are obviously annoying, especially when they are crawling on our favorite plants and trees. But biodiversity is important, so don’t make it your goal to take out every cherry blackfly or cherry aphid you spot. Cherry blackfly (Myzus cerasi) is an aphid that sucks sap from the foliage. This insect overwinters on the tree as eggs, and the aphids hatch in summer. Check the undersides of the leaves this month. If they are covered with shiny black aphids, you’ve identified the issue. You may also see leaves that are crumpled and curled. However, the aphids will leave the tree in summer, so if the damage is not severe, it might be better to leave them.

While a minor aphid infestation won't ruin your crop, severe leaf curling can compromise the tree's ability to photosynthesize, reducing the overall sweetness of this year’s fruit. If you must intervene, avoid harsh chemical insecticides that harm native pollinators. Instead, use a firm, targeted blast of water to dislodge colonies, or apply a gentle organic insecticide or insecticidal soap late in the evening. Arber Organic Bio-Insecticide Concentrate from Walmart is an exceptional planet-safe biological treatment that targets sap-suckers. Alternatively, import predator bugs. You can get a box of live ladybugs at garden stores and let them eat the aphids.

5. Trim Gently for Light and Airflow

It’s not a good idea to do a major cherry tree prune while cherries are ripening, for obvious reasons. But after your cherry harvest, it is a good idea to prune in July. It’s useful to prune sweet cherry trees every year to keep them compact. However, it's more important for tart cherries, since they bear their fruit on the ends of the branches. If branches get long and scraggly, they can break under the weight.

If you are gentle and reasonable with your cuts, July trimming can open up the inside of the canopy to airflow and sunlight. Take a good long look at the tree first to determine which branches are causing blockage problems and limit your trimming to these. Using clean shears or pruners, remove the least amount possible to open up the canopy. Use team favorites Fiskars Bypass Pruning Shears from Amazon, or Corona Forged Steel DualCUT Bypass Pruners from Walmart, for razor-sharp cuts that make clean, fast-healing cuts on fruit wood.

Cherry trees are highly vulnerable to fungal diseases like silver leaf and bacterial canker when pruned during cold, wet seasons. So the warm, dry midsummer window is perfect, as the exposed wood heals rapidly. Good pruning basics include removing dead, damaged, or diseased wood, alongside aggressive water sprouts shooting up through the center of the canopy. Opening up the center allows sunlight to reach the lower interior branches, which is beneficial for future ripening and sugar conversion.
