Hi there I planted pumpkin about a month or 2 ago and there's 3 medium sized pumpkins on the plants but I had to removed 2 already due to rotting and I also found worms inside the rot. Can you tell me what the problem is and what can I do to get rid of it? I will really appreciate it if you can help.

I find that sometimes I have a lot of male flowers and few females, and sometimes the oposite happens. I guess that is why we fertilize by hand. Jane

Dear Adam If you spray your pumpkins or squash with milk (diluted in water anything from 1 part milk 2 parts water if you are treating to weak solution of 1 part milk 10 parts water if you are preventing) you will NOT have ANY problems with mildew. The milk works better than anything you can get commercially. Cheers Dana

I grow pumpkins every season. If you want your pumpkins to grow big you must make sure the entire plant gets watered and fertilised regularly as the vine sends down a root at about 1/2m intervals in search of water and food. When you start getting female flowers (with a pumpkin attached) you need to fertilise them by getting pollen from the male flower, just put your finger inside and you will see the pollen on it, gently brush it on to the middle of the female, once pollinated the new pumpkin will go into a growing frenzy, (I know they are about 90% water ) Water, water, water! And food, My best Kentia/ Jap went 12.2 kg 33cm high, save the seeds and keep them in the freezer. Veggies are the best.
