Let me introduce to everyone the knowledge about why pumpkins overgrow without producing fruits, let's take a look together.
Why Don't Pumpkins Produce Fruits When They Overgrow
Pumpkins are a vegetable commonly planted by farmers. They are easy to grow and have high yields. If you plant a pumpkin, you will get several large ones. However, some people say that their pumpkins grow in vain, their leaves are very green, free from diseases and pests, they look strong, but they don't produce fruits. What is the reason? Let's find out.
The Reasons for Pumpkins Overgrowing Without Producing Fruits
Pumpkins are very sensitive to soil, water, and fertilizer. They are a plant that likes fertilizer and water. If the soil in the planting area is rich in fertility, it can easily cause pumpkins to have excessive nutrients and show an overgrown state.
If there are many pumpkin flowers but no fruits, you should consider whether it is due to insufficient light or excessive nitrogen fertilizer. Additionally, one possible reason for pumpkins not bearing fruit is insufficient pollination, leading to fewer fruit-setting flowers.
Preventive Measures for Pumpkins That Only Bloom Without Setting Fruit
1. Grape Pruning
When the pumpkin vines grow to 2 meters long, the main vines should be pruned, removing the growing points of the main vines, and the main vines should produce branches. The number of branches should be controlled at 3 to 4 to increase the rate of flowering and fruit-setting.
2. Build a Climbing Frame
When the pumpkin branches and vines grow to 2 meters, they should be guided to grow upwards. Because if the vines are too concentrated, they can easily block each other, leading to weakened photosynthesis and不利于病虫害防治. After the vines are established, pumpkins can enjoy ample sunlight and growing space, which is very helpful for the fruit-setting rate of melons, and can increase the flowering and fruit-setting rate by 40%.
3. Control Pumpkin Overgrowth
If the pumpkin is too long, it can easily result in fewer fruits on the vines, so it is effective to inhibit the excessive growth of the vines. A folk method is to cut a slit 30 centimeters away from the root of the vine and stuff it with a small piece of charcoal or hard wood, which can effectively inhibit the excessive growth of the vines.
4. Pollination
The female flowers on the non-lush grape trees should be cherished. If you see female flowers about to open, you should cover them with pumpkin leaves to prevent moisture from entering the young flowers. The next day, when you find the female flowers, cover them with male flowers from other plants for three days. This auxiliary pollination can also increase the fruit-setting rate.
5. Other Matters
Old leaves, especially yellow and withered leaves, should be removed in time, and male flowers should be removed. The removal rate should be 30% of the entire vine, reducing nutrient consumption.
