[Conifers and shrubs](https://dunger.ua/en/blog/categories/conifers-and-shrubs) # When to move established thuja: timing and aftercare Published 2026-11-15 Updated 2026-11-15 To read 7 min Assess whether a thuja can be moved, choose suitable conditions, protect its root ball and organise watering and aftercare. Move a thuja that is already established in the garden during a cool period when the soil is workable and the plant is not suffering from drought. Early spring before vigorous growth is often a useful opportunity. Early autumn can also be suitable where local conditions allow roots time to re-establish before the ground freezes. A month on the calendar cannot guarantee success. The condition of the plant, the roots retained during lifting and the care available afterwards all matter. ## Before you start digging - Decide whether moving is necessary and whether the new position is genuinely better. - Assess the plant, access to its roots and the weight of the root ball. - Locate underground services and clear the route for moving the plant. - Prepare the destination, water and materials for protecting roots in advance. - Postpone planned work when soil is frozen or saturated, or hot drying weather is forecast. ## Moving an established thuja differs from planting a nursery pot A plant that has occupied the same site for years has roots extending beyond the ball that can be lifted. Moving it inevitably removes some of those roots. The crown remains, but its capacity to obtain water is temporarily reduced. Even a healthy-looking specimen can take time to recover, and survival cannot be promised simply because the foliage is green on moving day. Consider whether the benefit justifies disturbing the plant. Nursery stock has a different root history and may have been prepared for lifting. Advice that container plants can be installed through much of the growing season does not mean a large established thuja can be dug up in summer with the same risk. For a newly purchased plant, use the separate guide to [planting thuja](https://dunger.ua/en/blog/planting-thuja). Here the main task is retaining a functioning root system while changing the position of an existing specimen. ## Choosing between spring and autumn In spring, wait until the ground has thawed and is workable rather than smearing onto tools as a wet mass. Aim to complete the move before strong new growth and hot weather. A cold morning does not make a waterlogged bed suitable for excavation. Check moisture below the surface as well as where you first push the spade. Plan around the actual condition of both the old position and the destination. The autumn opportunity depends on the weather and the remaining time before lasting ground frost. Green foliage is not evidence that a late move will be harmless. Evergreens still lose moisture through their leaves, while injured roots and frozen soil restrict replacement water. In Ukrainian gardens where the transition to winter is abrupt, postponing a non-essential move until spring can be the more cautious choice. Avoid applying one regional date to the entire country. A calm overcast day reduces rapid drying of exposed roots. Postpone a planned operation during drought, severe heat or drying winds. If construction makes an immediate move unavoidable, treat it as a higher-risk operation and seek professional advice. Discuss whether the specimen can realistically be retained, what equipment will reach it and who will provide aftercare. Urgency does not remove the biological limitations of a reduced root system. ## Decide whether this particular plant can be moved Compare the alternatives before excavation. If the thuja obstructs one passage, changing the path or arrangement may avoid the move. An old specimen in a dense hedge can be difficult to lift without damaging its neighbours as well as itself. A declining plant needs an assessment of the cause first. Simply moving a diseased or badly stressed plant across the garden may carry the problem to another unsuitable position. Height alone does not determine feasibility. Root spread, soil texture, the integrity of the ball, machinery access and manageable weight all influence the decision. Involve a specialist before digging a large specimen. Preparatory root pruning can form part of professional planning, but it requires advance preparation. Arbitrarily cutting roots immediately before the move does not create a new network of absorbing roots overnight. Do not use a universal root-ball diameter for every cultivar and age. ## Prepare a site that resolves the original difficulty Identify the thuja species and cultivar, its expected size and its light requirements. Common western thuja cultivars need moisture together with drainage. A depression that remains saturated or a spot receiving concentrated roof runoff can undermine an otherwise careful move. Leave space for the future crown and practical access for inspection and watering. Check the position from the path and the house before committing to a new hole. Assess soil across the future rooting area. A small pocket of very different loose material within heavy wet clay does not automatically provide drainage. If improvement is needed, plan it before the plant is lifted. The guide to [soil for conifers](https://dunger.ua/en/blog/soil-for-conifers) separates site assessment from choosing a bagged mixture. Avoid treating the planting hole as an isolated flowerpot while ignoring the conditions roots will encounter as they grow beyond it. ## Protect the root ball during lifting Check moisture around the plant in advance. Moderately moist soil supports the roots better than a dry crumbling ball, but soaking the area into mud is not useful preparation. Gather branches loosely if necessary to create working space. Determine the excavation boundary from the actual plant and root system, not a circle copied from an unrelated specimen. Keep people and equipment clear of underground services and neighbouring plants. Support the ball from underneath and keep it intact. Never pull the thuja out by its trunk or use the stem as a lever. Use suitable strong material or equipment rated for the load. Shaking soil away to make a heavy ball easier to carry sacrifices the protection the roots need. Shield roots from sun and wind and minimise the interval between lifting and replanting. A prepared destination makes this much easier than starting the second hole afterwards. ## Set the root level before backfilling Find where the trunk meets the main roots rather than relying only on an old soil stain on the bark: the plant may already have been buried too deeply. Leave a firm base beneath the root ball so it does not settle lower after watering. Check that the plant stands correctly before filling the hole, while its position can still be adjusted without rocking a completed planting. Fill gaps carefully without stamping the soil into a compact slab. Remove ties that could constrict the trunk and release wrapping appropriately while preserving the ball. The treatment depends on the material and its support role, so ask the person handling a large wrapped ball to explain the sequence. Water after planting and check for settlement. Keep mulch away from the trunk base. Assess support according to stability and wind exposure; tight bare wire against bark is unsuitable. ## Aftercare is more than the first watering Check the original root ball and the surrounding ground separately, because they may dry at different rates. Water according to the actual need without turning the hole into a permanent reservoir. A green first week does not prove that establishment is complete. Moisture can still require attention in autumn and mild winter weather, but do not apply water to frozen ground. Agree who will inspect and water the plant when you are away. Do not remove a large part of the healthy crown to supposedly balance root loss. Removing broken growth and severe reshaping are different operations. When foliage changes colour, examine the location and progression: older inner foliage can shed naturally, whereas drying outer tips need a different assessment. The guide to [yellowing in thuja](https://dunger.ua/en/blog/yellow-thuja-diagnosis) helps separate these possibilities. Avoid responding to every colour change with another fertilizer application. ## Plan feeding after assessing the plant A suitable granular product can be considered when conifers need planned feeding. First assess the relocated plant and previous applications. Fertilizer does not replace roots physically lost during lifting, watering, correct planting depth or support. Moving a plant is not by itself a reason to add an extra portion to the hole.  ### [Complex fertilizer for coniferous evergreens, granules](https://dunger.ua/en/mineral-fertilizers/small-packaging/for-landscape-design/fertilizer-complex-coniferous-evergreens) DÜNGER compound mineral fertilizer in granules for conifers and evergreens.

Calculate the appropriate requirement before selecting packs. Do not transfer a rate from another formulation or use leftover granules as a reason to feed again. In [My Garden](https://dunger.ua/en/my-garden), save a thuja zone, its crop and measurements to plan the required product quantity. Check the calculation and pack size for the chosen method before adding it to the basket. Keep your cultivar name and relocation observations separately for your own reference. Check current price and availability on the product card when buying. ## Common questions ### Assess the root ball, weight, access and plant condition before starting. Large specimens require suitable equipment and professional help. Breaking the ball apart or cutting away many roots cannot be compensated for by stronger feeding. ### ### ### ## Rate this article No ratings yet. Be the first!
