Take the seeds and put them in some water for about 3 days. New water each day. That will take the flesh off them. Then let them dry for about 2 weeks. Then put them in a sealable jar and put in the fridge. Plants need to be planted about 1m apart and rows about 2m apart. They need a fair bit of garden to grow in. Depending on the size of the planter box you would need to pay attention to how much fertiliser you put on and water regularly.

Hello, My Kent pumpkin vine did very well this year producing nearly 30 pumpkins.. My question is while many are ready to harvest I still have baby ones starting to grow is this a normal thing for pumpkins. thank you .

I had apple cucumbers have 3 flushes of flowers to produce 3 lots of cucumbers. Pumpkins could do the same. It will then take another 50-60 days or so until you will pick these. The soil would have to have more fertilising or the pumpkins would be small in size. Consideration to, you have had a great crop, do you really want to keep going for 2 months more. I think like, I spent $1 on 10 pumpkin seeds and they produced $40-50 of produce, that is great value. Time to rip that crop out and prepare the soil for the next crop.

Hi, Central QLD here. Jap pumpkins. This season i planted 2 lots of 3 vines on the same day. One in full sun and the other in a shady area. The full sun ones are growing wee with lots of pumpkins. The ones planted in the shady area grew great looking healthy long vines but not a single flower, male or female. Have turned the water off these ones and will be pulling out in the next day or two. Need plenty of sunshine

Most vegetables need a fair amount of direct sunlight a day, 4-5 to 8+ our a day. In shade you will have weak looking plants. It tells you in the notes how far apart. Set the climate zone to tropical for planting times.

I also have seeds germinating from my compost and have at times so much produce have taken great joy in giving them away and hearing about the joyous results. I am out most mornings 2 hours after sunrise when the male stamen is all fluffy with pollen and the female has ants crawling around inside. I pollinate myself by gently picking and trimming the male flower because if I leave it to mother nature my crop is very small. I usually use 2 or 3 male flowers on one female just in case. Recent rains have not been helpful for flowers at all but 1 week later flowers are appearing and just this morning I watched a bee laden with pollen flying from flower to flower. It was so laden it had trouble flying. I love mother nature she is the best for people like me.

Just found this - commercial production. For efficient pollination and fruit set, there must be: both male and female flowers and bees to move pollen from male to female flowers. A number of factors can influence pollination, Cold and overcast days limit pollination activity of bees. Hot dry conditions desiccate pollen making it unviable. Rapid growth promotes earlier flowering. However, high temperatures, long days and high rates of nitrogen can result in: vigorous vegetative growth and few flowers and a higher proportion of male to female flowers. It is important to check the sex of the flowers. A ratio of 1 female to 7 male flowers is usually considered adequate. Flowers open early in the day and for one day only, and they close by mid afternoon. These periods are shorter under high temperatures. Flowers are most receptive to pollination in the morning when bee activity is usually the highest. Bees are necessary for pollination and must be active in the crop. Flowers require at least 12 bee visits for good pollination. If bees are not plentiful, introduce at least two hives per ha after female flowers appear and male flowers start producing pollen. Spread hives around the field outside the crop, preferably so that bees have to fly over the crop to get to another food source. Destroy flowering weeds around the crop.
