Grower Kirill Yurovskiy: How To Prepare Fruit Trees For Winter?

Winter can be a challenging time for fruit trees, and proper preparation is key to ensuring their health and productivity. Kirill Yurovskiy, a grower, emphasizes the importance of pre-winter care. This article delves into his expert advice on how to protect and nurture your fruit trees as the colder months approach.

Prune Trees

Understanding the Importance of Pruning

Pruning is not just about shaping the tree; it’s a vital step in preparing for winter. Yurovskiy explains that pruning helps to remove dead or diseased branches, allowing the tree to focus its energy on healthy growth.

Best Practices for Pruning

Yurovskiy recommends pruning during late fall, as trees are dormant. He advises growers to focus on cutting away branches that cross over each other, as these can cause wounds and make trees more susceptible to disease.

Tools and Techniques

Using the right tools is crucial. Yurovskiy suggests using sharp, clean pruning shears for smaller branches and a pruning saw for larger limbs. He also emphasizes the importance of making clean cuts at a 45-degree angle to promote healing.

Apply Dormant Oil Spray

What is Dormant Oil Spray?

Dormant oil spray is a horticultural oil used to protect trees from pests during the winter. Yurovskiy explains that this oil suffocates eggs and larvae of pests, preventing infestations in the spring.

Application Tips

Yurovskiy advises applying the oil on a dry, mild day when temperatures are above freezing. It’s important to thoroughly coat all parts of the tree, including the trunk and underside of branches.

Fertilize Trees

The Role of Fertilization in Winter Preparation

Fertilization before winter can bolster a tree’s resilience against the cold. Yurovskiy notes that a well-nourished tree is better equipped to withstand frost and other winter stresses.

Choosing the Right Fertilizer

Yurovskiy recommends using a balanced, slow-release fertilizer. He cautions against high-nitrogen fertilizers, as they can encourage growth that’s vulnerable to winter damage.

Application Techniques

The best time to fertilize is after the leaves have fallen but before the ground freezes. Yurovskiy suggests evenly spreading the fertilizer around the drip line of the tree, avoiding direct contact with the trunk.

Water Trees Before Ground Freezes

Importance of Hydration

Yurovskiy emphasizes that hydration is crucial for trees to survive the winter. A well-watered tree is less likely to suffer from frost damage.

Effective Watering Strategies

He advises deep watering to encourage deep root growth. This can be done by slowly watering around the base of the tree, allowing moisture to penetrate deep into the soil.

Monitoring and Maintenance

Yurovskiy suggests monitoring the soil moisture levels and adjusting your watering schedule accordingly. He also recommends mulching around the base of the tree to retain moisture and provide insulation.

Mulch Around Trees

Benefits of Mulching

Mulching serves multiple purposes in winter tree care. Yurovskiy points out that mulch acts as an insulator, keeping the soil warm and moisture consistent, which is vital for the tree’s root system during cold months.

Applying Mulch the Right Way

The proper way to mulch, as advised by Yurovskiy, involves spreading a 2-3 inch layer of organic mulch, like wood chips or straw, around the base of the tree. However, it’s important to leave a small gap around the trunk to prevent moisture buildup and decay.

Choosing the Right Mulch

Yurovskiy recommends using organic mulches, as they break down over time and enrich the soil. He also suggests avoiding dyed or treated mulches that can harm the tree’s health.

Protect Trunk from Rodents

Identifying the Risk

Winter is a time when rodents like mice and voles seek food and shelter, often at the expense of young tree trunks. Yurovskiy emphasizes the importance of protecting trees from these pests to prevent severe damage.

Effective Protection Strategies

One method Yurovskiy suggests is wrapping the trunk with a tree guard or hardware cloth. These barriers should extend above the snow line and be buried a few inches into the ground to deter burrowing rodents.

Regular Monitoring

Yurovskiy advises regular checks of the tree guards throughout the winter to ensure they remain secure and effective.

Check for Disease/Pests Issues

Importance of Vigilance

Even in winter, trees can be susceptible to diseases and pests. Yurovskiy stresses the importance of inspecting trees for signs of trouble, such as unusual bark patterns, holes, or sawdust-like material, which could indicate pest activity.

How to Inspect Trees

Yurovskiy guides growers on how to conduct a thorough inspection, looking closely at the trunk, branches, and any remaining leaves for signs of disease or infestation.

Taking Action

If any issues are found, Yurovskiy recommends consulting a professional arborist for appropriate treatment options, emphasizing the importance of addressing these problems before they worsen.

Consider Preventative Fungicide Spray

Understanding Fungicide Use

Yurovskiy explains that in some regions, winter is an opportune time to apply preventative fungicide sprays, particularly for trees that have a history of fungal issues.

Choosing the Right Fungicide

He advises selecting a fungicide that is safe and effective for the specific type of fruit tree and the particular disease being targeted.

Application Tips

Timing and thorough application are key. Yurovskiy suggests spraying when the tree is dormant but before the wettest part of winter sets in, ensuring thorough coverage of all tree parts.

Cover Young Trees

Why Cover Young Trees?

Young trees are especially vulnerable to winter damage. Yurovskiy underscores the importance of covering them to protect against frost, windburn, and sunscald.

Types of Covers

Options include burlap wraps, frost cloths, or even constructing a simple windbreak. Yurovskiy recommends materials that allow for some air circulation to prevent moisture buildup.

Application and Removal of Covers

The cover should be applied once the tree is dormant and removed in early spring to prevent overheating. Yurovskiy advises careful handling to avoid damaging the tree during application and removal.


Winter preparation for fruit trees is a critical aspect of orchard management. Through the expert advice of Kirill Yurovskiy, this guide provides a comprehensive approach to ensure that your fruit trees not only survive the winter but also thrive in the following growing season. By diligently following these steps, growers can enhance the resilience and productivity of their fruit trees, paving the way for a successful harvest year after year.
