Why Tomato Plant Have Flowers But No Fruit

Many gardeners love to grow tomatoes, but when weather conditions are not favorable, it can be challenging to get them to produce fruit.

But apart from temperature, there other factors that may also lead to your tomatoes producing flowers without fruits, such as low growing conditions and irregular watering practices. However, Tomatoes do not thrive well when the weather is extreme; too hot or cold.

That said, below is a breakdown of the most common causes of why tomatoes may have flowers but no fruits.

1. High Heat Levels

Once in a while, in hotter atmospheres, high temperatures can serve as destruction with pollination, thereby causing the main challenge for farmers.

During Hot spells, when daytime temperatures stay above 30ºC (86ºF) and evening temperatures fail to drop underneath 24ºC (75ºF), they negatively impact turning pollen sterile. Hence pollination won’t take place. Although tomatoes like it hot but extreme heat is usually not in their favor.

In this type of situation of a heatwave, the only option you’re left with is maintaining healthy plants by ensuring adequate watering measures.

Simultaneously, you await the perfect opportunity for when the temperature drops to be in good conditions for more production through self-pollination once temperature allows.

Don’t forget that different tomato varieties are suited to different climates. If you’re in the hot part of the world, grow a heat-tolerant variety that is recommended for your region.

Before cultivating tomatoes, remember that tomato plants are diverse and different varieties fit various atmospheres.

So, it would help if you carried out enough research on the best tomato plant variety for your location. Some tomato variants are heat tolerant and can preserve through the heat and set fruit if you’re living in a hot region.

In such a situation, regular watering may help raise the mugginess from the humidity around the plants enough to improve conditions.

Some tomatoes are known to be large producers, and some are mostly sought after for their sizeable organic product.

Tomato fruiting varieties like the Mortgage Lifter typically produce several six tomatoes only for each plant for the whole season.

When you need an abundant tomato plant yield, a rule of thumb is to use the smaller heirloom variety like red brandy wine, which is a massive producer and provides a much beautiful and medium-size fruit.

3. Insufficient Fertilizer (or the Wrong Type)

Another factor to consider is soil fertility. Are your tomato plants getting the nourishment they have to develop full, plump, and delectable natural products?

Whether you have rich soil, from the second the primary flowers show up, it would help if you took care of your tomatoes with an organic fertilizer rich in potash or potassium. Potash supports flower commencement, and eventually, fruit creation.

You can easily maintain tomatoes with an off-the-shelf tomato fertilizer or make your high-potash liquid fertilizer for free. Every garden should have a clump of comfrey for home-brewed fertilizer.

Keep tomatoes took care of with off-the-rack tomato manure or make your high-potash fluid compost from home.
