Roses are prone to more pests and diseases in sultry summer weather. It is important to maintain a regular check on blackspot which loves hot humid weather.
Maintain moisture levels and increase watering especially during hot, dry conditions. Don’t prune rose branches heavily during summer. Wait until the hottest part of the summer is over. Liquid feed with SeaMax Fish & Kelp to reduce plant stress from floods or drought. Keep soil well mulched and weed free.
Keep the leaves and stems as dry as possible and water the soil only when caring for the plan to reduce the risk of fungal diseases and leaf damage in humid, damp weather. Water more often during heatwaves as your rose will lose more moisture through evaporation.
