What needs doing now for healthy rose growth this year?

Good preparation gives the rose the best chances of growing strong and healthy so your garden will maintain colour and fragrance throughout the summer. Ideally, the hole should be dug a few weeks in advance ensuring well rotted mature or compose is well forked into the bottom. When the rose is ready to be planted, add mycorrhizal 'ROOTGROW' to the base of the hole ensuring the rose roots come into direct contact with the friendly fungi. Keep newly planted roses watered until well established in the ground or container. This is especially important during prolonged dry weather spells.
It is now April and pruning should now have been completed. Your roses will now be in active growth with new leaves and shoots appearing on the stems in good numbers. Always re-check for any winter die back on stems and prune off brown or black stems if evident.
Feed each of your roses with a proprietary granular rose feed containing iron and magnesium. Sprinkle a handful around the base of each plant and lightly rake into the soil. Should your rose experience no rain fall the following days after applying, water the rose. Feeding is very important for roses and is crucial to maintaining long term healthy growth, increasing the number of blooms and improving flower and leaf colour. Finally, check standard rose stakes, trellis, fences and arches for possible winter decay and repair or replace where necessary, tie in any long new growth on climbing roses.
