Baby lemons often fall off the tree due to water stress, particularly during late spring and early summer. When the tree doesn't receive enough water, the small fruits can dry up and detach.
Understanding Lemon Fruit Drop
It's natural for lemon trees to drop some of their young fruit, but excessive fruit drop can indicate an underlying problem. Here's a breakdown:
Causes of Baby Lemon Drop:
- Water Stress:
- Dry Conditions: A lack of adequate water, especially during crucial growth periods in late spring and early summer, can cause fruit to dry out and fall off. The reference states that, "Water stress during the late spring and early summer is a common cause of the little fruits drying up and falling off the tree."
- Inconsistent Watering: Fluctuations in soil moisture levels, either too wet or too dry, can stress the tree.
- Other Potential Factors:
- Nutrient Deficiencies: Inadequate nutrients can weaken the tree and its ability to support fruit development.
- Pollination Issues: Poor pollination can lead to undeveloped fruit that the tree eventually sheds.
- Natural Thinning: Trees naturally thin out fruit to ensure adequate resources for the remaining fruit.
- Pest or disease infestations: Infestations or disease can cause the tree to shed fruit.
Identifying Water Stress
Here are some signs of water stress to look out for:
- Wilting Leaves: Drooping or wilting leaves are a clear indication of dehydration.
- Yellowing Leaves: As referenced, "If the lack of water is severe enough or occurs frequently, it may also cause leaves to yellow and fall off the tree."
- Dry Soil: Check soil moisture regularly, especially during hot or dry periods.
Solutions to Reduce Fruit Drop
- Consistent Watering: Establish a regular watering schedule, especially during dry spells and the fruit-setting period.
- Deep Watering: Water deeply but less frequently to encourage deep root growth.
- Monitor Soil Moisture: Use your finger or a soil moisture meter to determine when to water.
- Mulching: Apply a layer of mulch around the base of the tree to help retain soil moisture and regulate soil temperature.
- Fertilize Appropriately: Provide a balanced citrus fertilizer to ensure adequate nutrients.
- Pest and disease control: Regularly inspect your tree for pests and diseases.
Conclusion
Baby lemons falling off the tree are often a sign of water stress. Ensuring your lemon tree receives adequate and consistent watering, especially during the critical late spring and early summer months, can significantly reduce fruit drop.
