'Herkules' Shrub Rose

The main problems for roses are aphids (greenfly) and rose black spot - although many of the newer varieties have good resistance to it. Greenfly can be removed by hand and squashed, or if you don't fancy that you can wipe them off with a damp cloth or spray the area with a water, soap and vegetable oil mixture. Black spot appears as unsightly patches on leaves but doesn't usually harm the plant unless it takes hold. In extreme cases, growth can be stunted. Check regularly and remove any affected leaves, making sure to remove any fallen leaves or petals as soon as possible, as the disease spores are stored here and can reinfect the soil, affecting the next season's growth. A good preventative measure is mulching with wood chip or manure around the base of the plant so that rain doesn't splash any soil-borne spores onto the plant's foliage. It's also a good idea to water at the base of the plant and prune it to maintain an open, airy framework - this will prevent mildew and mould.

When roses are newly planted, you should water them every 2-3 days, unless you’re planting bare root between November and March, when the weather should be wet enough. As the weather warms up, you should water your roses once a week, but watch out for dry spells during spring and summer. If the flowers start to wilt or droop, it’s a sign that they need more water. Always water your roses as closely as possible to the base of the plant and avoid splashing foliage or flowers as this can encourage disease or mould. A soft spray is better, so if using a hosepipe, a rose attachment is perfect. Pay special attention to roses in pots, next to walls, in sandy soil and when newly planted and don't allow the soil to dry out completely.

For the best flowers, plant in a sheltered spot where your rose will receive around 6-8 hours of sunlight daily in spring/summer.

Roses do well in most soil types, as long as they're well drained - they hate their roots to be waterlogged - and not too dry. Loamy soil is perfect. If your soil is very heavy or sandy, mix in some garden compost and perlite (or horticultural grit) when planting.

Feed your roses in late March/April at the start of the growing season and again in late July after the first blooms have finished. Sprinkle a granular rose food over the soil - this will release its nutrients over several months, promoting healthy growth and repeat flowering.
