Brett, Are you using bought seeds or saving seeds from pumpkins? If you have bought seeds, it might be worth contacting the supplier and telling them about your problem. Otherwise, if you saved seeds, see the answer to Jean's query.

Ray, your pumpkins are falling off early because they are not fertilised. You may need to go around with a paintbrush and transfer pollen from the male flowers to the female. Check the comment from Jaci to identify which is which.

Jean, you may be lucky. If you had an organic pumpkin it will probably produce both male and female flowers but if it was a F1 hybrid then its seeds will produce sterile plants. Check the flowers for possible female ones (see comment from Jaci above).

Great to hear of someone so young who wants to grow things. If this attempt fails, tell her to try next year. Plant around April/May and grow into the winter. If you have or can make a garden bed, tell her to try growing some radishes - nearly the easiest thing to grow. Go to Bunnings or a nursery and buy some punnets of lettuce or other things she likes and plant them. When starting out it is a lot easier to plant seedlings. The hard work has been done to germinate them. Also buy a little container of fertiliser (about 2kg or so) from nursery or Bunnings etc. I use a watering can (9 liters) and add a small tupperware cup of fertiliser to the water. Give it a good stir. Scale this down to say 1/2 to 3/4 of a tablespoon in 1-2 liters of water. Wait until the plants have grown to 3-4-5 inches. Little plants little fertiliser and more as they get bigger. Good luck.
