Most roses also require regular applications of fertilizer to reach their full potential and produce wonderful flowers.
During the next four weeks, a water soluble, balanced fertilizer such as Miracle Gro “For Roses” or Nurseryman’s Rose food should be applied the first week. Midway through the month, apply half a cup of Epsom salts, an essential element in the growth process of roses.
Good cultural practices include watering correctly. Watering overhead only in the morning, so the foliage can dry out prior to the evening, can prevent some diseases.
Watering carefully with a soft nozzle will eliminate soil or mulch from splattering on leaves. This reduces the opportunities for diseases, such as black spot, from gaining a foothold.
Pest management begins with controls other than chemicals. This may involve hand picking worms or water-washing aphids from your roses.
Natural controls like ladybugs and praying mantis can also keep insects pests under control. However, there are those times when an invasion of pests will overwhelm such nontoxic practices.
Although I don’t necessarily espouse establishing a regular spray schedule for roses, you may never see any evidence of problems if you spray your plants every two weeks with a systemic rose product.
However, remember that this chemical will kill both pests and beneficials.
All garden chemicals should be applied thoughtfully and carefully.
Look for next week’s column to highlight control of rose pests and diseases.
To describe roses as romantic is to open them and myself to a degree of misunderstanding... but certainly they are the evocative flowers of association.
Beyond their unquestioned beauty, the heavenly scent of our roses keeps me lingering in my garden each morning, and simply because I still enjoy being in Catharine’s and their company.
See you next time.
