A Simple September Routine
If your lemon tree looks like the one in the image, you can follow a straightforward routine.
Step 1: Inspect the tree
Look carefully at the leaves, branches and fruits.
Check for pests or signs of disease.
Step 2: Check the soil
Don’t water according to a rigid schedule.
Check the moisture first.
Step 3: Water properly
When the soil begins to dry, water thoroughly and allow excess water to escape.
Step 4: Check the sunlight
Make sure the tree receives plenty of bright light.
Step 5: Feed responsibly
If the tree is still actively growing, use an appropriate citrus fertilizer according to the manufacturer’s instructions.
Step 6: Look at the fruit load
If a small tree is carrying an unusually large number of fruits, consider whether thinning some of them would help.
Step 7: Be patient
Don’t remove healthy green lemons simply because they are still small.
Why September Can Be an Important Moment
September is a useful time to reassess your lemon tree because it sits between the peak of summer growth and the changing conditions that follow.
The tree may still be actively developing fruit, but its needs can gradually change.
This is the moment to make sure that:
the roots are healthy,
the soil is not staying waterlogged,
the tree receives enough light,
nutrition is balanced,
and the developing fruit isn’t under unnecessary stress.
Small corrections at this stage can make a significant difference over time.
Avoid These Common Mistakes
Overfertilizing
Adding extra fertilizer won’t automatically produce bigger lemons.
Watering every day without checking the soil
The correct watering frequency depends on temperature, pot size, soil and growing conditions.
Keeping the roots constantly wet
Good drainage is essential.
Putting the tree in deep shade
Lemon trees need plenty of light.
Removing healthy fruit too early
Small green lemons may simply need more time.
Repotting unnecessarily
A larger pot isn’t always the solution.
Pruning heavily
Don’t remove healthy foliage without a good reason.
The One Thing You Should Do Now
If you want to give your lemon tree the best chance of developing its small fruits, start by doing something very simple:
Check the soil and the overall condition of the tree before changing anything.
If the tree is healthy but the fruit is simply developing slowly, avoid trying to force it with excessive fertilizer or water.
Instead, maintain consistent care.
Give it adequate sunlight.
Keep the soil appropriately moist but well drained.
Provide balanced nutrition.
And give the fruit time.
Your Small Lemons May Still Have Plenty of Time
The most important thing to remember is that a small green lemon in September isn’t necessarily a problem.
Fruit development takes time, and lemon trees can carry fruit through different stages of development.
If the tree is healthy and growing under good conditions, those small green fruits may continue to enlarge and mature.
So before reaching for another fertilizer, changing the pot, or removing the fruit, take a closer look at the basics.
Sometimes the best thing you can do for a lemon tree is surprisingly simple:
give it enough light, enough water, balanced nutrition, good drainage—and then let nature do the rest.
A little patience now could be exactly what your lemon tree needs to turn those small green fruits into a much more satisfying harvest.
