Why is it recommended to avoid growing pumpkin near potato plants?

We have both jap and butternut pumpkins growing but seem to only have male flowers. Do we pull them out and start again. There is plenty of male flowers

Hi Cheryl, pumpkins and the like start off with plenty of male flowers, so that when the female flowers form (which should be any time now) there are plenty of male flowers to be able to pollinate them. When the pumpkin runners get to about 3 meters pinch out the tips and they will put out more runners thus giving more crop. Cheers Gary

Usually the first flowers on a plant are male - be patient! These are used to pollinate the female flowers that will form shortly.

Just a point, pumpkin female flowers only open one day - until about mid arvo. If no bees, break off a male flower and pollinate the female flower with it. I did this the other week - two different f flowers in three days. One grew one died. ????

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.

I was given a Jap pumpkin and I grew a Qld blue earlier this year. The Jap was by far the better for flavor. When I was growing the Qld blue it rained (heavy) several times and the female flowers were very wet inside and just rotted. If no bees plant some flowers (research flowers for bees) around your yard. I'm doing this as I have very few bees I think. Also it is best to grow pumpkin into winter I have read. It wouldn't make any difference if using seeds or seedlings. I have two Jap pumpkin growing now - will be interesting to see if they produce.

I was starting to cut up some pumpkin the other day for scones. Hard skin pumpkin to cut. Then I thought - give the pumpkin skin a good wash, cut the pumpkin up and cook it - then peel the skin off - a lot easier.

In a large garden plot how far apart should potatoes and pumpkins be planted?
