Also, if you decide to replant roses in the areas your infected plants were, you should replace the soil in a broad/deep area around the former root zones. This is a two-fold rationale: 1. The existing soil may be contaminated with the RRD mites. 2. In general, when planting a new rose in a previously planted (with a rose) zone, you should replace the soil. This is because there are old nematodes from the previous rose in the soil that can potentially damage or hinder the new rose roots, causing the new rose to suffer from 'Rose Replant Disease'. Additionally that old soil will presumably have been depleted of nutrients by the previous occupant. Soil replacement is time consuming, heavy work, but it is worth it, if you want your new rose(s) to thrive.
