Planting Advice for Magnolia Susan Trees

Our pot grown Purple Magnolia 'Susan' can be planted at any time of the year. Firstly, remove all weeds and grass within a metre of your desired planting hole. Dig a square hole as deep as your root mass and approximately 2x as wide. To help your Magnolia establish more effectively, sprinkle root grow in the hole.

Gently remove the pot but do not try to loosen the roots of Magnolia trees before planting. They have a fleshy root system and can be quite fragile. Using 50% of the original soil and 50% compost, fill in the hole and firm around gently. Make sure not to bank the soil up around the collar of the tree.

For tree forms of Magnolia Susan, we recommend using a stake and tie kit and rabbit guard when planting, but these are not needed for the bush forms. The help and advice section has further information and videos.

Aftercare Advice for Purple Magnolia trees

If you’re planting Magnolia in spring or summer, water well for the first few months. Increase watering if there are extended periods of hot or dry weather. Magnolias do not cope well with dry soils so this is especially important. If planting in autumn, you may only need to water a little. Irrigation kits make it easier.

Once planted, keep the area free of competing weeds and grass for the first couple of growing seasons. If your area is prone to rabbits, use a rabbit guard.

Pruning Advice for Magnolia Susan trees

If pruning to limit the overall size, stagger your pruning over a few years to alleviate the stress on your tree. Pruning for Purple Magnolia should be carried out in mid-summer to early autumn. Avoid pruning in late winter to early spring.

Below are definitions of various forms, which refer to the shape of the tree defined by the pruning it has received. For more advice, please contact us.

Single Stem / Pruned and shaped: Classic shaped tree with a single stem that has had pruning to help create a beautiful, natural shape.

Top grafted: A height noted next to this form refers to the length of clear stem, which will not grow taller. Only the head of branches will develop. Top grafted trees do not require complicated pruning and are ideal for small spaces.

Multi Stem: A multi stem tree is has two or more stems arising from or near ground level, growing from one root system. Take care to buy a true multi-stem like all ours and not those that are 3 saplings in a pot to cheaply imitate them.

Feathered: A feathered tree has branches from the bottom of the trunk all the way up. These branches can be removed if a clear stem is required.

Bush: A plant with many stems low down, rather than one clear stem.

Climber: A plant that is a natural climber and will be delivered usually running up a bamboo cane, ready to position in the garden.

Standard Tree: A more mature tree with an upright clear stem of approximately 1.8m-2.0m (measured from the soil to the lowest branch), which supports a branched crown. Standards are available in different forms relating to their girth size (circumference of the stem measured 1m above soil level), not height.
