Roses Need Your Attention This Month: How To Make The Most Of The Crucial Feeding Window

Few flowers feel more at home in a British garden than the rose. From climbers to scented shrubs, they're one of the most dependable ways to fill a garden with summer scent. But the display we enjoy in June is shaped much earlier.

As February closes, it's time to prepare for the spring feed. The main feeding window for roses runs from March to early April, and getting the timing right makes a real difference for stronger summer blooms.

When should you feed your roses?

Roses might look bare and lifeless right now, but feeding works best as they come back into growth. As buds begin to swell and the first shoots start to push, the roots are ready to take up nutrients and channel them into the stems that will flower in early summer.

The RHS rose growing guide puts it plainly: "Feed twice a year: in March/April before flowering and again in mid-summer after the first flush of flowers."

That March or April window coincides with the first signs of growth, when buds swell and fresh shoots appear. Feed too early, while the soil is still cold or waterlogged, and much of that goodness may be lost before the plant can use it. Wait until buds are swelling and growth is just beginning, and you're backing the stems that will carry the first flush of summer flowers.

Specialist breeder David Austin's rose feeding advice echoes the same point: "Apply it in late March or early April, just before the new growth starts," adding that correct timing helps to "encourage strong, healthy growth and abundant flowering."

Other rose jobs to tick off this week

While the main rose feed comes in March or early April, late February is about getting everything in place.

Start with pruning. The RHS guide to pruning roses recommends pruning bush and shrub roses in late winter, just as growth begins. Cut back to outward-facing buds and remove any dead or crossing stems to encourage strong, well-shaped new growth.

Next, clear the base of the plant. The RHS advises removing fallen leaves to reduce the risk of disease, particularly rose black spot, which can overwinter in debris.

When growth begins, apply a balanced granular rose fertiliser around the root zone, keeping it clear of the stems and lightly working it into the soil. Follow with a mulch of well-rotted manure or garden compost, leaving a small gap around the stems to protect the base.
