Hi folks! This is potentially outside the scope of this community but Im hoping some botanistically minded people might be able to help me out here. I have several rose plants on my property and Ive always wanted to harvest the rose hips. The problem is they turn yellow and then rot long before the first frost.
I was wondering if anyone knew why this might be?

When was the last time you fertalized? Roses need to be fertalized 2-3 times a year (get a slow release formula specifically for roses). Your roses might also benefit from bonemeal to restore potassium to the soil. Lastly, is the yellowing because of rot/fungus? Cooler, humid climates cause numerous infections on roses, but are easily managed with garden sulphur.
Not sure if this will save this year’s rose hip harvest, but it will help for next years.
