Planted mid Feb - that is only 3-4 weeks ago. I would give it some time to let the plant grow. Read back 20-30 comments here. Male flowers first then female. You are arid - maybe too hot. Consider when it is a bit cooler.

I thought I’d give growing Butternut Pumpkin a go but planted them in January. They’ve all grown & have big leaves. I know I planted them late but was wondering if I will I get pumpkins growing from these plants? Or have I wasted my time?

Your plants aren't very old yet. give them time to produce some male and then female flowers. Hand pollinate if you have no bees. Read back a page or tow of comments here - a lot of info. Your big leaves maybe from too much nitrogen/very rich soil. Pumpkin take about 16 -20 weeks before picking.

Probably plant pumpkin now and leave the potatoes until April.

How do stop pumpkins rotting on vine

The female flower is there for a few days - if it is not pollinated then it will rot and fall off. If you put water into the flower it will probably rot. The flower is only open for one morning so hand pollinate it if you don't have any bees. There is a shortage of bees world wide. It might be a bug/disease and I have no idea. Have the plants out in the open and not in shade damp areas. Water low and in the late afternoon - no water into the female flower.

Butternut pumpkins...planted mid Nov'. do they change colour & sound hollow when ripe? we are a bit dubious when to harvest.

Why would I not be getting female flowers on my butternut vines?
