I have just purchased some Mc Leay mongrel seeds but I am having issues finding information online regarding the species. Is anyone able to assist? Does it come under a different name?

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.

Hello Wazza,, I've had simular results with My pumpkin , but just be a bit more patient and I'm sure the Male Flower's will soon appear,, I know it's frustrating waiting but it will happen soon.

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?

Google "Gramma Pumpkin seeds" and you will find where to buy them. I can't put other company names on here. .
