Many times we do our best to ensure that our vegetables, shrubs or fruit trees lack nothing and are healthy so that they can give us a good production, on the other hand it sometimes happens that they do not bear flowers or fruits or they fall before their time, why is this happening? In today’s article, we are going to look at 10 possible causes.

Climatology
A drop or rise in temperature during full bloom in the spring can be catastrophic as it can cause the flowers to drop suddenly. Undesirable phenomena such as frost or haze are the ones that usually cause problems. During the flowering period, the plants are more sensitive and there are more and more frosts at times that do not correspond to them due to climate change.
A remedy for frost is the use of thermal blankets and to remedy the heat it is advisable to apply good irrigation to avoid water stress which can cause the fall of flowers and fruits.
Excess nutrients
If the flowers give rise to the fruit but it does not grow or falls prematurely, it may be because we have gone too far with the nutrient supply. It is better to add a little fertilizer because it is more difficult to correct an excess than a lack of nutrients. Plants with excess nutrients show symptoms such as leaf scorch (brown), leaf yellowing, slow growth, or death due to blocked roots. If we detect that it is an excess, it will be necessary to water abundantly to wash the soil.
Lack of nutrients
The lack of nutrients also causes the flowers to drop because at this time they require a large amount. It is advisable to contribute what is recommended and not to exceed it. Another option is to provide a liquid fertilizer that reaches the plant beforehand, such as earthworm humus tea.
Lack of water
It is important not to stop watering during the flowering period because a lack of water can cause the premature fall of flowers or fruits. For this, it is better to consult the weather forecast which will be throughout the week to know if you should water your garden more or less frequently.
Lack of light
Both vegetable crops and shrubs or fruit trees need a minimum number of hours per day to be able to bear fruit. Before planting, we must observe where the sun shines throughout the day and the hours of sunshine required for each crop. Some vegetables are more shaded and tolerate fewer hours of light.
Autogamous trees or crops
Some plants and trees are self-pollinating, but others need other factors like wind or insects. A clear example is papaya trees, you can buy a female from the store and it will never give you papayas because they need male papaya flowers to be able to pollinate. It is necessary to know whether the chosen trees or crops are self-pollinating or whether more than one must be planted to obtain fruit. Tomatoes should be pollinated with bees or by shaking the plant.
excess humidity
If we have excess humidity due to excessive irrigation or the type of soil and the water does not drain well, it can happen that the roots of plants or trees rot. It can also cause other illnesses. If the soil is clay, the supply of organic matter must be improved and if it has rained it is not necessary to water as often. Sometimes mulching can become an inconvenience if it rains too much in your area.
Fungi and pests
Some fungi can attack the flowers and therefore the fruit will not develop. It can also happen that we have pests such as thrips, they usually live in the flowers where they feed, causing premature fall. Other pests can also cause premature fruit drop, such as Ceratitis capitata or fruit fly or olive fly. The adult flies bore through fruit or flowers and lay their eggs. Fighting these pests is complicated because they must be prevented by trapping.

Lack of pollinators
If you live in a city, pollinators most likely won’t be able to reach your garden, so you need to plant a few flowering plants to get their attention. And in the garden, it is always advisable to have a hedge of aromatic and flowering plants or you can also mix them between crops. Flowers that are not pollinated fall, this problem usually happens a lot in pepper plants. One solution if you don’t like pollinators is to use a brush and run it over each flower to pollinate them.
fruit time
Some fruit trees take time to bear fruit, for example tropical pineapples usually take 1 year to start fruiting. It is important to be knowledgeable and patient.
