Tend to the roses

If you have roses that need tending, take advantage of pleasant days and consider the following chores.

PRUNE >> First on the list is to prune them. Remove all dead, diseased canes and branches. On hybrid teas, floribundas and grandifloras, try to remove an older cane or two to encourage new cane growth this summer. With climbers, prune to shape. Always clip back canes and twigs to an outside bud.

FEED >> Because of the warm, wet weather this winter, many roses are beginning to push out new growth. Now is a good time to begin feeding with an all-purpose rose fertilizer.

MULCH >> Mulching goes a long way in smothering weeds and conserving moisture later this summer. It also conditions the soil, helping make fertilizer and water more available to plant roots.

SPRAY >> If rust, black spot and powdery mildew were a problem last summer, now is the time to consider spraying with a winter rose spray. Copper-based sprays work well if applied at least twice at two week intervals. Disease-prone roses should be sprayed with an organic rose fungicide once leaves flush out. Baking soda-based sprays, sulfur fungicides and bacillus-based sprays work well if applied on a regular basis. All are organic.
