I Purchased Two Home Run Rose Plants A Week And A Half Ago.

Question

I have not planted them. It’s unusually hot here (Peterborough, NH). I water every night — the leaves are turning yellow. I probably watered too much–what should I do to stop the leaves from yellowing and get it back to a healthy plants.

Answer 1

I suspect one or both of the following: Overwatering
or heat stress. Both are treatable.

Overwatering or sitting in water can lead to yellowing leaves in roses because it causes root rot and deprives the roots of oxygen. This prevents the roots from absorbing nutrients properly, resulting in nutrient deficiencies and yellowing leaves.

On the other hand, heat stress can also cause yellowing leaves as it can lead to excessive transpiration and dehydration of the plant.

To correct these issues, it is important to ensure proper drainage for the plants and avoid overwatering. Additionally, providing adequate shade and reducing heat exposure by putting them in shade on occasion can help prevent heat stress. Regularly monitoring the moisture levels in the soil and adjusting watering accordingly, as well as providing appropriate temperature and humidity conditions, can help restore the health of the plants and prevent further yellowing of the leaves.
