Even the most vibrant roses can suffer from pests such as aphids, otherwise known as black flies. British gardeners are no strangers to warding off bugs, but the key to keeping rose bushes looking their best often lies not in harsh chemicals, but in natural solutions. 

Feeding and pruning are crucial rose bush requirement to keep the plant strong and resilient throughout the growing season. Mikey Leach, head gardener at The Alnwick Garden in Northumberland, says: "Different species of roses have different care requirements, but if we’re looking at the more modern English shrub roses, think of them as hungry plants."

According to Mr Leach, consistent feeding using well-rotted manure or diluted tomato feed high in potassium is essential for encouraging blooms and repeat flowering.

While watering should be minimal on fertile, loamy soil, roses in free-draining ground may need a weekly soak, especially during warmer spells.

But even with the best care and conditions, pests can still be a persistent issue, particularly in mid to late summer when the garden is in full swing.

Chemical sprays may offer a quick fix, but many gardeners are seeking safer, organic alternatives that are kinder to the environment and other insects. 

That’s where one particular natural remedy, neem oil, has grown in popularity among those looking to keep their rose beds beautiful. 

Neem oil, derived from the seeds of the neem tree, has long been used in organic gardening for its multi-purpose pest-fighting properties.

This golden-hued oil works by disrupting the feeding and breeding cycles of common garden pests without harming pollinators such as bees and hoverflies.

When diluted and applied to roses during the early morning or late evening, neem oil acts as a deterrent for everything from greenfly to fungal diseases like powdery mildew. 

Mr Leach adds: "I’m not a fan of pesticides and believe that nature rules, however, if you do need to help stop disease or disrupt pests such as black fly, neem oil is a fantastic organic treatment which works brilliantly if used regularly."

Regular use can even reduce the likelihood of re-infestation, making it a useful addition to any natural rose care routine.

Alongside neem oil, companion planting is another low-maintenance trick that can help bolster your roses’ defences.

Mr Leach suggests planting garlic relatives such as Allium "Ambassador" or "Globemaster" next to rose bushes.
