Hi. We live in Zone 9. We were able to get beautiful pumpkin plants and florets, but never produced a pumpkin this year. We know they can grow bc there is a pumpkin farm nearby that produces plenty. I thought that I had only males, but then female plants appeared and still no flower. We started them in Late July, I think. Any advice?

My pumpkins plants get big beautiful blooms, only to fall off. Is this bloom blithe, or a pollination problem etc.? ,

In a large garden plot how far apart should potatoes and pumpkins be planted?

The only real consideration is to allow the pumpkins to spread if they are the 'running' type. Bush pumpkins can grow to about six feet across and you would need a bit of space to work around them. potatoes could be planted about a foot apart. The limit there is more on the available nutrients in the soil and management of the plants. Trust this helps.

IT says not to plant pumpkins in the same bed as potatoes. How far from potatoes can pumpkins be planted?

Which varieties grow a large, round, and deep orange vegetable that can thrive in my area, and what's the best way to plant them?
