When Rose Diseases Aren't: William, Greensand will provide adequate potassium for your r

» Mark_Whitelaw - William, Greensand will provide adequate potassium for your r

Greensand will provide adequate potassium for your roses, but the use of most time released fertilizers is governed by temperature. The higher the temperature, the faster the nutrients are released.

For now, I would concentrate on keeping your roses alive with water. And although the nutrients will surely be leached away with your continuous watering of containered roses, their NPK needs at this time of year are minimal for your zone.
