We list the 5 main reasons flowers might not appear when you expect them.
Let’s start problem-solving!

1. Timing
From the time you sowed seeds in the ground, you should expect them to germinate within seven to 10 days. About eight weeks (or 50-55 days) after that, you should start seeing flowers.
This is about halfway through the pumpkin’s 100-120 day growing time, depending on the variety.
Here’s a tip: the first flowers you see are male. The biggest visible difference between male and female flowers is that males don’t contain an ovary like females do. The ovary looks like a tiny lump just behind the flower.
The flowers unfold at dawn. In the next several hours, they open more and more until they are graceful golden basins at their peak of beauty.
These hours are critical for pollination, whether you’re depending on bees or pollinating the plant yourself.
The pollen on the male flower’s stamen must get transferred to the female flower’s stigma, covering the whole segmented head.
2. The Soil
If you aren’t seeing flowers even after more than 55 days, it’s possible that the soil your pumpkins are growing in has too much nitrogen, which contributes to lovely leaves but not to flower production.

Or maybe it has a workable amount of nitrogen but not enough phosphorus.
Phosphorus is responsible for helping plants set fruit, and it’s integral to the flowering process.
Remember that pumpkins need nitrogen too, so you’re not trying to eradicate or even greatly diminish the content.
The main thing is to let a few other plants benefit from it while adding phosphorus to help those plants bloom.

If daytime temperatures persistently rise above 90°F with little to no reprieve at night, your plant may be too stressed to produce flowers, which takes a lot of its energy and nutrients. Instead, it switches to a survival mode of sorts.
You might be skeptical that the sun could cause such damage to a sun-loving plant.
But take this example, which happened to me recently: I sowed several rhubarb plants from seed in containers this winter.
As soon as our extra-long Alaskan summer days hit, they thrived in their warm windowsill spot, growing thicker stalks and huge (for their age) leaves.
If you see powdery white stuff on your pumpkin vines or leaves, take action quickly. Remove the affected leaves and grab an organic fungicide to treat the plant.

Some fungicides are preventative, others are intended to treat an existing infestation, and some do both. So pay attention to what you’re spraying your plants with.
Spraying an existing fungal outbreak with preventative fungicide won’t do much, while adding a curative fungicide to non-infected plants can be a waste of time and money.
And if you live in an extra wet, rainy area, it’s worth spraying your plants with preventative fungicide early on in their growth.
Also, when you’re removing leaves, be sure to wash your hands between plants and even between infected and not-yet-infected leaves on the same plant.
The last thing you want to do is pluck a mildewed leaf off one vine, only to use that same hand to touch a healthy nearby plant or leaf, thus spreading the spores.
Any fungal infection could affect blossoming if the disease lowers the overall health of the vines and leaves, delaying blooming or even killing the plant.
But with quick and early treatment, you should be able to avoid this.
May They Bloom and Grow Forever
Well, maybe not forever. But now that you know the five main culprits that may cause a lack of blossoms, you’re ready to get those plants healthy and blooming.
And you know what that means – baby pumpkins coming soon to a plant near you. Oh, the excitement!
In the meantime, keep an eagle eye out for those pumpkins, like my three-year-old does. He adores checking on them. He even uses binoculars to get an extra-close look.
