Sweet pea flowers

Question

I cannot get sweet peas to mature into a flower. When is the best time to grow them? The sun can be too much for them all day, I found, or do I need shade for them. Do they like what kind of soil? I need help because I have gone through about 10 packs of seeds.

Answer 1

They do enjoy sunlight, but in high temps will need extra water to compensate for the inevitable heat stress. If they are healthy but not blooming, they likely do have too much nitrogen. Give them some phosphorus to balance them back out. Bone meal is a good source of phosphorus.
