Pruning Ohio’s Fruit Trees

Pruning shears and clippers come in various sizes.

Pruning excessive vegetation from fruit and deciduous ornamental trees in Ohio's ever-changing climate helps bring about strong healthy flowers, drupes, pomes and nuts. When it comes to growing fruit and nut trees in the Buckeye State, a solid-yet-flexible pruning schedule geared for Ohio’s ever-changing weather helps to produce a good seasonal crop. Whether your trees are in a grove, sizeable orchard or merely decorating a backyard landscape, “cropping for crops” is the phrase to remember; prune for a healthy and more bountiful harvest. Popular fruit trees growing in Ohio include apples, cherries, peaches, pears and plums. For happy squirrels and wildlife in your yard, be sure to trim up oak and walnut trees, too!

Prune Trees Because …

Trimming excessive vegetation helps fruit grow larger.

Too many shoots and twigs will stunt fruit growth. Old brush and dead branches prevent sunlight from soaking into greenery -- clearing out all this debris allows trees to develop stronger and healthier flower buds. Trees that are “un-snipped” can produce fruits too, however, their lesser yield may lead to smaller or diseased pomes and drupes. Apples and peaches, for example, grow larger and will ripen better when their trees’ sunlight-produced-food supplies head directly to foliage, buds and fruits (instead of unnecessary leaves or branches). Along with helping the tree develop a well-shaped canopy, pruning and removing unwanted brush allows rainwater to better access tree roots.

Watch the Thermometer

Ohioans know it; our weather is sometimes (often) unpredictable. Cold winters can turn into cold springs, or, perhaps, early warmer springs bring frigid temperatures into the month of May. Unseasonably “warm” winters can lead to cold springs -- just when you think the danger of frost is passed (by mid May or so), your newly-embedded fruit or vegetable plants get “zapped” in falling temperatures. Planting fruits, vegetables and flowers in Ohio can be a guessing game too, especially in northern areas of the state. When it comes to pruning fruit (and all kinds of) trees in Ohio, the goal is to trim branches before they spurt new growth; during the dormant season in early spring (after the snow melts and temperatures reach above 32 degrees Fahrenheit). Ohioans hope that’s in March, but it may be April or into May. These “rules,” however, are really only guidelines because the true determination of when to prune varies with each particular tree species and where it grows. However, broken or falling tree limbs should be removed as needed.

Snip, Snip!

Larger growing fruit trees that have not been trimmed in several years can undergo some “major snipping,” says Ohio State University Extension. Thickly-set or main branches that come off the trunk at 90 degree angles are typically the strongest offshoots; however, those growing parallel are fairly weak -- especially if they show signs of rotting. When using a hacksaw to cut limbs measuring more than 3 inches around, make the first slice at about 12 inches from the branch collar or trunk. Cutting the top areas first will ease the weight of the limb, making it less likely to break during the entire removal process. Snip the smaller branches and shoots with a sharp pair of pruning shears or clippers. For fruit-producing trees, trim branches by making small, thin slices just past the flowering buds. Early spring is typically best but in Ohio, most types of plum, cherry, peach, apple and pear trees -- as well as nut producers -- can be trimmed during the late part of dormancy. For best results, spread the snip-sessions over a couple of seasons.

Tree Scars

Callus formation -- scabbing on closed wounds -- is different for each species. Typically based on size and environmental factors, wound scars develop calluses much like human skin. Air circulation allows deeply-pruned or wind-damaged trees to thicken faster. Some arborists recommend wound painting (applying a tar-like substance over the break) but in Ohio, letting oxygen get to the open sore on an otherwise healthy tree is a better way to facilitate the healing process, says OSU Extension.

The Basics of Growing Fruit Trees

Bite into that tangy peach, crunchy apple, or juicy pear and experience the satisfying moment, especially when it comes directly from your own backyard. When planting fruit trees in Ohio, consider these factors:

  • Space. Each tree sapling must have enough room to grow. Tree size (height and width) at their maturity varies with type and species.
  • Pollinator. Does your desired fruit tree need a mate? Learn the facts: ask a garden store expert before you buy. Trees (some peach varieties, for example) may need a second variety planted nearby for pollination.
  • Location. Direct sunlight and good earth; test your planting soil for pH levels. Soil pH determines whether the dirt is acidic (sour) or alkaline (sweet). The pH scale runs from zero to 14, with 0.0 being the most acidic and 14.0 is the most alkaline. A neutral pH value is at 7.0. Ohio’s pH ranges between 6.0 and 7.0.

Remember ...

It's a good crop this year!

Trees need six to eight hours of full sunlight each day and well-draining soil. Cutting back branches so they’re evenly-spaced allows more room for flower buds and developing fruits. Trimming newly-planted trees to heights of around 30 inches helps them develop a good, aesthetic shape. The little sprigs of vegetation on the trunk may look cute, but if not removed, they will develop into strong branches and offshoots that can damage or hinder the tree. Thin out the buds every couple of years or so; too many fruits will weigh branches down and cause stunting and disease.
