I grew Jap/ Kent pumpkins on neighbours empty block from Aug 14 till Now May18. Used wick feeding on some for a marginally better growth rate. Plantings were 5 no plants to a volcano shaped ditch which had raw kitchen waste and paper dug deep - 450mm. Used really weak liquid manure e.g. work liquor 1 to about 400 applied every third day as the watering. Encouraged bees with some colour plants lobellia etc. Fantastic result some 30 plus very large pumpkins approx 5kg plus. Recommend this method if you have room else grow in trees and spt with panty hose. John

ref: April 4. Cut off one of 8 pumpkins and made soup. They are definitely ready. My freezer is full of soup for the winter. Thank you all who answered my email. Appreciated.

They need hand pollination. Had same problem at the beginning but ended up with 8 after manually fertilizing them. Bit late now but keep in mind next time.

Ive learnt that the first time my butternut pumpkins bloom, they bloom only female flowers, but the bext time they produce both. Not sure why, but many in my area say the same thing. I actually stopped at a large farm growing them to ask, why mone wouldnt produce fruit after flowering, and they told me it wouldnt the first time. However hand polination was needed the first time, after that the bees and insects did it all for me.

Have large pumpkin vine which produces green pumpkins about tennis ball size, but then they all turn dark brown and shrivel up and fall off. What can I do?

Thank u Cindy and Keith. My pumpkins are about 2kgs in weight but turned from green stripes to yellow with tinges of green. They are solid and now have 9 on the vines but they are all going the same way. I have hand pollinated a couple but cannot understand why they are "yellowing". Am tempted to cut one open. your views appreciated!!!!

Geraldine, each pumpkin plant should produce both male and female flowers. The earliest flowers that emerge will be male and all up there will be more of them produced in total than female. You may or may not have to encourage pollination. If you have bees hanging around they'll do it for you. Consider making your vegie patch more enticing to bees by companion planting some bright flowers (like calendula, nasturtiums, french marigolds, sunflowers, etc) to attract them. Anyway, the way to tell the difference between male and female flowers (in case you didn't already know) is that female flowers will generally have a bulbous base near the stalk, below the flower. Also, since they take up a lot of room, have you considered training the pumpkin vine along a fence or up the side of a garden shed? A workmate of mine had them fruiting up on his shed roof last summer.
