Empty flower in zucchini – what to do?
In this article, we will talk about the following situation. Here the flowering of zucchini begins with might and main, you did everything right, but bad luck … there are no ovaries on zucchini. Now we will consider the causes of this problem, and what to do in this case.
As we know, zucchini is an unpretentious plant of the pumpkin family, which contains a lot of benefits (potassium, iron, all kinds of vitamins, and so on). It is because of this that we always expect a huge harvest when we start planting zucchini in our garden. Unfortunately, sometimes our desires may not come true … so what is the reason?
Seed too young
Sometimes the reason may be that you start planting seeds too early. They may still be quite young. It is recommended to keep them at the beginning for about 3 years, and then only engage in planting. Be sure – it will only bring benefits.
The place for planting zucchini is not at all suitable
NOW LET’S TALK ABOUT A MORE FAVORABLE PLACE FOR PLANTING SEEDS
Always plant zucchini separately, in a new place. They do not like to bloom where cucumbers, pumpkins, or watermelons, for example, were previously planted. Wait about five years after the last harvest and you can safely plant your zucchini there.
Zucchini seeds are best planted in places with moderate alkali in the soil. The alkali level should be pH 6-6.8. If the soil is acidic enough, then zucchini may not produce ovaries at all.
Well, in order for the soil to reduce its acidity, then try dolomite flour or ash (about a pound per square meter with high acidity, somewhere around 0.3 kilograms with medium, and with low – 0.2 kilograms is enough).
Too densely planted seeds
Yes, that’s a big reason too. The distance between them should be sufficient for the development of fruit growth and for the ovaries to appear. If the planting was too thick, then this may interfere with the full development of the plant.
If planting has already taken place, and the plant has grown, then simply thin out its leaves.
Zucchini is a plant that is strongly affected by temperature changes. If it is cold outside, then in principle it may not give ovaries.
Try to cover your zucchini, for example, with spunbond, if the weather outside is not summer at all. But in the heat, we recommend that you spray them with boric acid and water in a ratio of two grams per ten liters.
Improper watering is also one of the possible causes.
In order for the ovaries to appear, briefly stop watering the plant. After all, excessive watering contributes to the development of only male flowers, by the way, as well as heat.
Deficiency of “vitamins”
The lack of good nutrition is the next possible reason for the rather poor flowering.
Top dressing of zucchini should be once every 2 weeks. Add two or three tablespoons of nutrients to ten liters of water and feed the roots of the plant. You can use for this a tool such as Azofoska, for example.
Let’s think. Perhaps your zucchini lacks sufficient pollination that comes from bees or butterflies? Do they even exist in your area?
To “call” bees to you, for example, try sprinkling a honey-water solution on zucchini in a ratio of two to three tablespoons per ten liters.
It is also likely that insects are denied access to the plant itself during the cool period. Try to periodically remove the shelter so that the insects can do their “work”.
But you can try and help yourself to ensure that the ovaries appear. To do this, every morning (until they appear) take a male flower (without an ovary and with a long thin stem), get rid of its petals and apply to every female flower that is on the plant.
Overabundance of ovaries
It is possible that the fruits stopped growing after the first harvest. This means that there are a lot of formed ovaries on the zucchini. On one of your bushes, about 4 female ovaries should grow simultaneously, preferably no more.
Try to feed the plant with Nitrophoska in the ratio of fifty grams per ten liters of water, and treat the bush itself with fruit-stimulating agents to avoid this problem.
Be sure to share with us your reasons for this problem and how you deal with them. We wish you a great mood and successful fruitful seasons!
