Lemon Farming: What Causes Lemon Flower And Fruits To Drop; Know Methods to Control

Citrus trees typically lose part of their immature fruits in order to narrow out the harvest and focus energy on the fruits that remain. It's common for 80 to 90% of the fruit to fall off the tree between the time the blossoms fall and the time the fruit gets a diameter of around 1/2 inch.

Citrus is a widely grown fruit. The citrus family includes a number of significant categories, including lemon. It's most famous for its pulp and juice all around the world. Lemon tree fruit drop is a physiological condition that happens in all citrus varieties. Pre-harvest fruit drop, on the other hand, is a source of concern for growers since it can result in considerable output reductions as well as the conversion of tree resources into non-harvested fruit. The proportion of fruit set and the severity of fruit drop in Lemon varies greatly among the major fruit crops.

Normal Lemon Fruit Drop

Citrus trees typically lose part of their immature fruits in order to narrow out the harvest and focus energy on the fruits that remain. It's common for 80 to 90% of the fruit to fall off the tree between the time the blossoms fall and the time the fruit gets a diameter of around 1/2 inch. A tiny amount of fruit might continue to fall from the tree as it matures. Fruit drops from a lemon tree in three stages.

When 70 to 80 percent of the flowers on a Lemon tree fall off without ever bearing fruit, the first drop happens. The Lemon tree produces pea-sized fruit about a week later. In the spring, when the fruit is about the size of a golf ball, the third drop happens. However, unless the premature fruit drop is substantial, these decreases are not reason for alarm. Lemon tree fruit drop is caused by environmental conditions that you can't control in many circumstances. Premature fruit drop can be caused by sudden temperature fluctuations and strong rainfall.

The Most Prevalent Reasons For Lemons Falling Off a Tree Are:


Drought causes lemon trees to become stressed. They'll abandon their fruit in favour of photosynthesis-producing plant leaves. If your rainfall has been exceptionally low, be sure to deeply hydrate the Lemon tree on a regular basis and preserve mulch around the base to conserve water in your soil.

Severe Temperature Changes

A fast temperature change is another reason why lemons are falling from the tree. That response happens as soon as the fruit starts to emerge. Temperature variations, whether high or low, have a negative influence on the tree at this point. Citrus canker can occur when there is a lot of heat and a lot of rain. Apply a copper spray to this.


The possibility of pests must also be considered. Lemon trees are a favourite of mites. Lemon fruit may drop as a result of their presence. If this is the case, consider applying an organic insecticide.

Nutritional Deficiencies

A lemon tree may occasionally alert you if it isn't getting enough nutrition before it starts to drop. The leaves of your Lemon tree will turn yellow if it does not receive enough Nitrogen. Yellowing between the leaf veins is caused by a lack of magnesium, zinc, and iron. The pH of the soil might also be a problem. If you're unsure, get the soil tested at a nearby nursery. After that, you can make changes based on the results.


All citrus trees benefit from minor trimming, however excessive pruning will result in dropping fruit. Lemon should only be pruned when there are dead branches to be removed from the region. Before August, prune in the summer. This will not stifle fresh growth.

Excess Fruit

If you have an abundance of fruit on your Lemon tree that you aren't using, pick and preserve it. The Lemon tree is stressed by too much fruit. It will decline in self-preservation if it can't support all the Lemons. On the plus side, the remaining fruit has a higher taste quality.

Uneven Watering

Lemons might fall from the tree due to uneven watering (as well as flowers). Trees need to be watered on a regular basis. Drought and low humidity are not good for them. To minimise excessive fruit drop and other Lemon tree issues, proper water management is essential. Lemon fruit drop can be caused by over irrigation, poorly drained soils, or drought stress. Citrus trees, on average, require gradual, deep watering every 5 to 14 days during dry, hot weather, depending on the age of the tree, and every 14 to 30 days during cold, wet weather, or whenever the soil 6 inches beneath the surface near the Lemon tree feels dry to the touch.

Lemon Tree Flower Drop Is Caused By a Variety Of Factors

Lemon plants are susceptible to environmental changes. Lemon flowers might fall off due to sudden changes in temperature or environment. Trees thrive in a sunny, permanent location where they may flourish all year. They require full light for a good bloom and fruit development, and if put in too much shadow, they may lose their blossoms. Lemon blossom drop on outside trees can be caused by unseasonably chilly spring weather in locations that are generally warm. Lemon blooms and buds that have been frost nipped will become brown and mushy, then fall from the tree.

Lemon trees are cultivated in pots in cooler areas and moved inside or out depending on the weather. Because of the numerous environmental changes they face when they are moved in and out, these potted Lemon trees are more prone to Lemon bloom and leaf drop. A lemon tree shedding blossoms might indicate dryness or other irrigation issues. To save energy when water is short, a Lemon tree will lose its blossoms and fruit. Lemon blossom drop can be caused by flooding, saturated soil, or overwatering. Lemons thrive in well-draining soil with consistent irrigation, particularly during periods of extreme heat and drought.

Encourage Lemon Trees To Bear Fruit

In the fall, water the tree deeply and regularly, and in the winter, reduce the quantity of irrigation. In the spring and summer, resume deep watering since these delicious fruits require a lot of moisture to develop. In the spring, fertilise with suitable food, including phosphorus, to enhance flowering and fruiting, then trim as needed. Fruits ripen on the ends of branches, thus dead wood and problematic branches should be removed. Protect the Lemon tree against illness and insects by taking the necessary precautions as soon as you notice a problem. Lemon plants that are in good health generate the most fruit.

Lemon Tree Fruit Drop Prevention

Dropping fruit on a lemon tree may be avoided, since it can be caused by improper watering or fertilisation, excessive pruning, or insect infestations. When there is less than 12 inches of rain in a week, water lemon trees. Also, carefully pour water to the soil around a Lemon tree, allowing it to soak in. When the water starts to flow off, come to a halt. Wait 20 minutes before watering again if you have heavy clay soil. Too much water depletes the soil's nutrients, while insufficient water strains the Lemon tree.

Lemon trees require a healthy balance of nitrogen, other macronutrients, and a range of micronutrients. Using a Lemon specific fertiliser, you can supply the tree with all it need. Follow the directions on the label for the best results. Lemon trees are infested by whiteflies, aphids, scales, and mites. Although these insects seldom inflict major harm, they can cause premature fruit drop and blemishing. When the insects are at the larval or "crawler" stage of their lifecycle in late winter and early spring, use narrow-range horticultural oils.

Insecticidal soaps or neem oil sprays are moderately successful in reducing adult insects on tiny trees, and a vigorous blast of water from a hose will knock some of the insects from the Lemon tree. Allow lemon trees to produce naturally as much as possible without trimming. Remove any dead, damaged, or diseased limbs as needed, but make as few cuts as possible if you want to keep the tree's size under control.
