Plants for under trees

It can be a challenge to establish plant cover under the canopy of large trees. Shade and lack of moisture are both problems in these conditions, but there are a number of plants that will tolerate these situations.


Plants growing under tree canopies suffer from lack of moisture and nutrients because of the competition from the trees. Another problem is the lack of light.

If your garden receives light shade or partial shade – perhaps receiving sunlight for two or three hours in early morning or late evening, the range of suitable plants may be wider and with some summer moisture, it would be worth trying plants from our Shade planting webpage.

Where the canopy is high and soil moisture is good, it may be possible to grow suitable plants directly under the canopy. The main flowering will be in spring with plants such bluebells, bergenia lily-of-the-valley and hardy cyclamen clustered around the base of the trunk.

Planting under trees with low or spreading branches is more restricted, and it may only be possible to grow plants at the edges of the canopy. Common ivy is worth trying in even the gloomiest conditions.

Practical considerations

Ground under conifers: It is very difficult to establish plants under conifers as the soil is dry and the evergreen canopy shades the site all year round. Often accumulating needles and debris create very acid conditions, making it difficult for anything, including grass, to grow satisfactorily.

Aspect: There is a greater chance of successful planting on the lighter south-west side of trees where rain is more frequently driven under the canopy, than to the north-east where conditions are usually drier and more shaded.

Planting and aftercare: Prepare the site by adding well rotted organic matter such as garden compost, farmyard manure or leafmould.

Autumn planting will allow plants time to become established before the leaf canopy develops in spring.  Deep mulching and watering in dry spells for at least the first full growing season are important for successful establishment.
