If your have heavy clay or boggy areas in your garden it is best to plant maples in pots or containers as you can easily provide the optimal soil profile as amending unfavourable clay soil to suit Japanese maple can be very difficult. Japanese maples do not grow very well in heavy clay or boggy areas of your garden and they are likely to die within a few years due to root rot or other fungal soil pathogens that thrives in damp soils. To effectively prevent Verticillium or any other soil pathogens that can affect maple the most important step is to ensure the soil is well draining and the planting areas has been amended with lots of compost or leaf mould to provide the optimal well draining soil structure.Īdding grit or horticultural sand to the planting area can also help to ensure the soil is porous which increases oxygen levels in the soil for root respiration and a healthy soil ecology and to increase drainage. Unfortunately it is very difficult to treat a maple with wilt and prevention is much better then cure. It is important to note brown Japanese maple leaves can also indicate drought stress, not enough water and too much fertilizer but if your maple is in waterlogged soil Verticillium wilt or root rot is almost certainly the problem. ![]() The symptoms of Verticillium are leaves that are turning brown, grey, yellowing and curling inwards or certain branches that drop all their leaves. Verticillium pathogens that affect Japanese maple thrive in damp soils and unfortunately Japanese maples are relatively susceptible to fungal pathogens caused by damp soil with even established maples trees suddenly displaying symptoms and dying. Growing in pots without drainage holes in the base.Īll of these factors can cause the soil to be saturated so that the roots are in boggy ground as opposed to well draining soil.The soil drains too slowly (heavy clay soil).Japanese maples can succumb to the disease Verticillium wilt or Phytophthora root rot in soils that are too damp because of: Japanese maples are adapted to growing in soils that are rich in organic matter (compost, leaf mould etc.) with a friable structure that absorbs moisture yet allows excess water to drain away quickly. Keep reading for why your Japanese maples is dying and how to prevent or or solves the problem… Japanese Maple Dying of Verticillium Wilt Or Root Rot However scorched or brown leaves can also be caused by too much wind, intense sun or a lack of water which can be solved with a few adjustments to the Maples conditions. The most common fungal pathogens that affect Japanese maples are Verticuillium wilt and Phytophthora (root rot) which are a problem in boggy soil and often kill the tree. ![]() Too much wind, sun and not enough water also causes maples to have brown, wilted leaves and a dying appearance. Saturated soil promotes the conditions for root rot which cause dying Japanese maples. ![]() Japanese maples (also known as acers) ‘ Acer palmatum‘ are small trees that thrive in well draining soil rich in organic matter, partial shade and when protected from wind.Ī dying Japanese maple is often because of fungal diseases pathogens that thrive in overly damp soils.
