I have grown trombone zucchinnis this year in amongst butternut pumpkins. Can anyone enlighten me as to whether they will cross pollinate.

I think that your trombone will be ready to harvest in about 60 days (from seedling to harvest date - called a summer squash) -- and I think that butternut squash (pumpkins) take closer to 120 days (from seedling to harvest date - called a winter squash) ==> my best guess is they will not be flowering at the same time; so no cross pollination will occur. If for some reason you staggered the planting so they were to flower at the same time; my best guess is YES they can cross pollinate -- squash seems to cross pollinate with other squash easily....however, this is just a guess based on what I know about other squash.

Tromboncino and butternut are both Cucurbitus moschato so would cross pollinate. As Cucurbits are pollinated by insects you would need to have a substantial distance between them (a few house blocks) to avoid this happening. If you want to save Tromboncino seed you would need to remove ALL of the male flowers off the butternuts as they appeared. The Butternuts would then be hybrid but the Tromboncino's should be pure. Check the botanical names of all pumpkins, squash, marrows, zucchinis, etc. before interplanting. If the specific name comes up with both, they will cross pollinate. Trust this helps

We have some healthy looking Zucchini Plants growing but unfortunately they are only producing female flowers. Not much good for fertilization. Can anyone give me a reason or solution to this problem ?

Be patient! The female flowers appear later in the season. I always plant 3-4 zucchini so that I have an abundance of flowers for pollination (which I do myself.)

I have had the same problem - all male flowers nearly - 3 different plantings - reason I have no idea.

Cucurbits produce lots of low energy male flowers for the first few weeks until a pollinator presence (bees usually) is established. Then, the females are produced. This is the pressure of natural selection. The ones that produce the most offspring dominate the gene pool. In this case later female flowering.

when do I start seedlings. I am new to gardening veggies but as a pensioner it keeps me busy. I am teaching my grandchildren both 8 years old to grow veggies. My 2 daughters are single parents.
