Summer Pruning Tips for 3 Fruit Trees Planted in 1 Hole, or High Density Planting

Nature Hills Nursery | February 14, 2026

Watch as Ed Laivo, one of America's top fruit tree experts, checks the growth on his latest high density planting of Burgundy Plum, Santa Rosa Plum and Emerald Butte Plum. During this video, you'll learn how how he makes summer pruning decisions to keep his fruit trees around 6 feet tall.

Growing 3 Trees in 1 Hole Delivers Great Fruit Set in a Small Space

Successfully planting 3 partner fruit trees together in 1 hole has a lot of benefits for your backyard orchard, including cross-pollination and enjoying an extended season of fruit. Keeping your high density plantings at a small size makes for easy homegrown fruit picking.

Summer is the best time to prune your high density planting. Ed says "The goal is to get good sunlight in the center of the three tree canopy. Pruning the aggressive spring flush of growth keeps your fruit trees to a manageable size."

Frequently Asked Questions

How close together should I plant fruit trees in a high-density or 3-in-1 hole planting?

For a true 3-in-1 hole planting, all three trees are planted together in a single hole, positioned just inches apart from one another rather than spread across the garden. This close arrangement encourages the trees to grow as a unified canopy while still benefiting from cross-pollination between compatible varieties. Choose three compatible fruit tree varieties and plant them together in one generously sized hole, then commit to regular summer pruning to keep the combined canopy manageable and around 6 feet tall.

How far apart do fruit trees need to be to thrive when planted in the same hole?

When planting multiple fruit trees in a single hole using the high density planting method, the trees are placed very close together, typically within the same planting hole rather than spaced apart. This technique, popularized by experts like Ed Laivo, works because summer pruning keeps each tree to around 6 feet tall, preventing them from competing aggressively for space and light. The key to success is selecting compatible partner varieties, such as Burgundy Plum, Santa Rosa Plum, and Emerald Butte Plum, which support cross-pollination and an extended harvest season. Focus on summer pruning to maintain an open canopy center and a manageable size for all three trees.

When is the best time during summer to prune fruit trees in a high-density planting?

Summer is the ideal time to prune fruit trees in a high-density planting, particularly after the aggressive spring flush of growth has occurred. Pruning during this period helps control tree size, with the goal of maintaining trees around 6 feet tall for easy harvesting. Focus your cuts on opening up the center of the canopy to allow good sunlight penetration across all three trees. Head out to your planting once spring growth has matured and remove any vigorous upright shoots that are shading the interior of the canopy.

How much of a fruit tree can I safely prune in summer without stressing or damaging it?

For high density plantings, focus summer pruning on controlling the aggressive spring flush of growth rather than following a strict percentage rule. The goal is to open up the center of the canopy to allow good sunlight penetration, which improves fruit quality and tree health. In general, avoid removing more than 20 to 30 percent of the canopy in a single summer session to prevent undue stress. Prioritize cutting back the most vigorous upright shoots first, and aim to keep trees at a manageable height of around 6 feet for easy harvesting.

Which branches should I remove first when summer pruning fruit trees planted together in one hole?

When summer pruning a high density planting, start by targeting the most vigorous, upright-growing shoots from the aggressive spring flush of growth, as these are the ones most likely to shade out the center of your canopy. Your primary goal is to open up the center of the three-tree canopy to allow good sunlight penetration, which improves fruit quality and overall tree health. Remove any branches that are crossing, crowding, or growing inward toward the center before addressing anything else. Work through each tree systematically, stepping back frequently to evaluate the canopy shape and ensure you are maintaining an overall height of around 6 feet.

How do I keep fruit trees planted in the same hole from growing too tall and shading each other out?

Summer pruning is your most effective tool for managing height and light in a high density planting. After the spring flush of growth, prune your trees back to keep them around 6 feet tall, which allows sunlight to reach the center of the combined canopy. Focus your cuts on the most vigorous upright growth, since this is what drives shading and competition between the trees. Head out to your planting in midsummer, assess which stems are blocking light to the interior, and make your cuts to open up the canopy and keep all three trees productive.

Should I prune young fruit trees differently than established ones in a high-density or 3-in-1 planting?

Young fruit trees in a high-density or 3-in-1 hole planting should be pruned with the same core goal as established ones: maintaining a manageable size, ideally around 6 feet tall, and keeping good sunlight reaching the center of the shared canopy. That said, young trees may require lighter cuts to avoid stressing new root systems while they get established. Summer is the ideal time for pruning in either case, as it helps control the aggressive spring flush of growth without triggering excessive regrowth. Focus your cuts on any vigorous upright shoots crowding the center, and stay consistent each summer to train your trees into a balanced, productive form from the start.

How do I open up the center of closely planted fruit trees to improve light penetration and airflow?

To open up the center of closely planted fruit trees, focus your summer pruning efforts on removing vigorous upright shoots that crowd the interior of the canopy. Summer is the ideal time for this work because the growth patterns are clearly visible and you can make informed decisions about which branches are blocking light. Aim to keep your high density planting around 6 feet tall by cutting back the aggressive spring flush of growth that naturally wants to push upward and inward. Step back frequently while pruning to assess light penetration, and prioritize removing any crossing or inward-facing branches that shade the center of the combined canopy.

Can I use the same pruning approach on multiple fruit trees planted in one hole as I would on a single standalone tree?

High density plantings of multiple fruit trees in one hole require a modified pruning approach compared to standalone trees. The primary goal shifts to managing the shared canopy as a single unit, keeping the overall height around 6 feet and ensuring good sunlight penetrates to the center of all three trees. Summer pruning is especially important for these plantings because it controls the aggressive spring flush of growth before trees compete too heavily for light and space. Focus your cuts on inward-growing and crossing branches to open up the center, and make this a seasonal habit each summer to keep your planting productive and manageable.

How often should I summer prune vigorous varieties like apricots, plums, or peaches when they are growing in a tight high-density planting?

For vigorous stone fruits like apricots, plums, and peaches in a high-density planting, plan to summer prune at least once or twice during the growing season, typically in early summer and again in midsummer if regrowth is aggressive. The goal is to keep the canopy at a manageable height of around 6 feet while maintaining good sunlight penetration into the center of the planting. Focus each session on cutting back the strong upright shoots that shaded the interior during the spring flush of growth. Check your trees every four to six weeks from late spring through August and prune whenever new growth is pushing the canopy beyond your target size.
