What to do, and when
The usual months for a UK garden. Your own plan gives the week.
Planting
Plant a pot-grown magnolia September to May. Moderate source: RHS.
Mulch the magnolia
Spread a thick layer of garden compost over the root zone, leaving 10cm clear around the stem.
Usually March to May, and September to November. Moderate source: RHS.
Prune the magnolia
Always cut back to a natural fork, so no unsightly stubs are left. From RHS.
Usually July to September. Moderate source: Gardeners’ World.
What the source words mean
Moderate: another trusted UK source, or the RHS on its group.
What not to do
Don’t prune in late winter or early spring
Cuts made then bleed sap. Prune only from midsummer to early autumn.
Moderate source: RHS.
