In spring and early summer, magnolias enchant with their large, goblet-shaped blossoms perched on bare branches. These ornamental trees and shrubs are a true delight, and their brief flowering period of just two to three weeks makes their beauty feel even more precious.
From now until June, magnolias will start dropping their pretty white to pink petals – and that's when many gardeners begin to wonder what to do next to ensure those ostentatious blooms return the following year.
As the head of plants at British Garden Centres, Julian Palphramand, explains, a hands-off approach is best at this stage. "Once your magnolia has finished flowering, the trick is to treat it gently rather than fussing too much," he says.
There are three essential steps to take now to help a magnolia through the coming months and prepare it for next year's flowering season.
1. Watering
Hydration is of the essence after flowering. "Water well through dry spells, especially in its first few seasons, and keep the roots cool and moist with a 2 to 5 cm layer of organic mulch spread around the base, but clear of the trunk," Julian advises.
"This simple routine helps the plant recover from flowering and quietly build up energy for next year’s show."
2. Pruning
It also helps to remove dead growth, although this should be done with care. "Pruning needs a light hand, because magnolias flower on older wood and many of next season’s buds are already set along the stems," says the plant expert.
"Only remove dead, damaged or crossing branches after flowering, cutting cleanly just above a bud or lateral shoot. If the tree looks congested, open it out gradually over a couple of years rather than cutting it back hard in one go. This keeps the shape natural and avoids sacrificing future flowers."
3. Feeding
Finally, your magnolia can benefit from a well-timed touch of fertiliser – with the emphasis on a touch.
"Feeding should be subtle, not heavy‑handed. A light application of balanced, slow‑release fertiliser in spring can support healthy growth without pushing lush foliage at the expense of flowers, but rich, high‑nitrogen feeds can work against you," Julian explains.
"Avoid feeding late in the season, when the plant is naturally winding down. If your magnolia is young or exposed to late frosts, a sheltered spot or a bit of protection can help next year’s buds harden off safely without damage."
Follow these steps and your magnolia should return the following year with bigger, healthier and more abundant blooms.
