With winter bringing cold temperatures, shorter days and the risk of frost, it can feel counter-intuitive to put new plants into the ground. However, for many types of trees, winter can be one of the best times of year to plant them, as long as you understand the conditions and choose the right approach. So can trees be planted in winter? And what should you consider before planting trees in your garden or grounds?
Why does winter planting often work well?
During winter, most deciduous trees are dormant. They are not producing leaves or flowers and are not actively growing above ground. This dormancy allows the tree to focus its energy on establishing roots rather than supporting foliage. As a result, trees experience far less transplant shock in winter than they would during warmer months. This means that you can move and plant them while they are resting, which reduces stress and increases the chance of successful establishment.
Soil conditions are also often favourable in winter. Autumn and winter rainfall usually keeps the ground moist, reducing the need for frequent watering after planting. As long as the soil is not frozen or waterlogged, roots can begin to settle in well before spring.
What are the best trees to plant in winter?
Winter is particularly suitable for planting bare-root and root-balled trees. These are commonly available from late autumn through to early spring.
Bare-root trees are lifted from the ground while dormant and sold without soil around their roots. They are cost-effective and establish quickly when planted at the right time. Root-balled trees, which come with a wrapped soil ball, are also ideal for winter planting as their roots are protected but still dormant.
Deciduous trees, including many native and ornamental species, respond especially well to winter planting. Hedging trees and fruit trees are also commonly planted during this period.
When is winter planting not advisable?
While winter planting offers advantages, it is not suitable in all conditions. You should avoid planting when the ground is frozen, covered in snow or excessively wet. Digging into frozen soil can damage soil structure, while waterlogged ground can suffocate roots and lead to rot.
Evergreen trees also require a more cautious approach. Because they retain their leaves year-round, they continue to lose moisture even in winter. If the soil is frozen or dry, evergreens can struggle to take up enough water, increasing the risk of stress or failure. If you do plant evergreens in winter, make sure that the soil is workable, and be sure to provide protection from drying winds.
Preparing the ground properly
Preparation is critical to successful winter planting. Before you begin, check that the soil drains well and is not compacted. Dig a planting hole that is wide enough to allow roots to spread naturally, but no deeper than the root system itself.
Improving the soil with organic matter can help with drainage and structure, particularly in heavy clay soils. However, you should avoid over-enriching the planting hole, as this can discourage roots from spreading into the surrounding soil.
Once planted, firm the soil gently around the roots to remove air pockets. Water thoroughly to help the soil settle, even if the weather is cool or damp.
Protecting trees after planting
Newly planted trees are more vulnerable during winter, particularly to wind and frost. Staking can be a good way to provide stability, especially in exposed locations, as this can prevent movement that would otherwise damage the developing roots.
Applying a mulch around the base of the tree helps to retain soil moisture and regulate temperature. However, it’s important to keep mulch clear of the trunk to prevent rot. Mulching also reduces weed growth.
At this stage, you may also want to consider garden edging around newly planted trees, particularly in lawns or mixed borders. Rubber garden edging, like FlexiBorder, helps to define the planting area, keeps mulch neatly contained and prevents grass or surrounding plants from encroaching on the root zone. This can make winter maintenance simpler and protect young trees as they establish.
In very cold areas, you may consider temporary protection such as fleece or wind barriers, especially for young or tender trees.
Watering and ongoing care
Although winter rainfall often reduces the need for watering, you should still check soil moisture regularly. Newly planted trees should not be allowed to dry out completely, particularly during dry spells or periods of frost when water uptake is limited.
You do not need to feed trees immediately after winter planting. Fertiliser is best applied in spring, when growth begins and the tree can make use of added nutrients.
Continue monitoring your tree into spring and summer. A well-planted winter tree will usually show strong growth once temperatures rise.
So should you plant trees in winter?
Planting trees in winter allows them to establish roots efficiently, before the demands of active growth begin. By choosing the right trees, planting in suitable conditions and providing thoughtful aftercare, you can take full advantage of the winter season.
