A Gardeners Forum Forums General Discussion The Food Garden Forum Vegetable Gardening Non-productive Pumpkin

Hi, I'm growing pumpkin from seed. They grow and grow in length, sometimes inches overnight, and they have been doing this for a couple of months now BUT there are no flowers / fruit. I wonder are we doing something wrong, such as letting them get too long ?

The climate here (Canaries - sub-tropical) is perfect for them and they are getting plenty of water - also, there is no sign of any pests.

They look very healthy - leaves and stalks are very green but the plant is simply growing in length and only leaves.

Any help would be appreciated - thanks.

Hi! I'm sorry that I don't have time right now to get a real answer for you-- like links & such. Plus, I am not at all familiar with your climate-- I'm a temperate person.

That said, I think if you do a search for "pumpkin day length" you might come up with something. Day/night length definitely affects flowering of many veggies. I cannot remember if the squashes are one of them or not.

It *could* be something you are doing, but ... . The only thing I can think of is that the soil is REALLY out of wack with respect to the N-P-K ratio. If there's way too much nitrogen (N) in proportion to phosphorus (P), and potassium (K), that would promote excessive vegetative growth at the expense of reproductive growth. But, unless you have been adding about a ton of manure a week, or an inorganic fertilizer that I've never heard of, I really can't see how it's anything you are doing.
