What to Do When a Potted Lemon Tree Drops Its Leaves? The Latest Solutions
Growing some plants at home not only beautifies the environment but also brings great joy; watering the flowers and plants every day is a kind of enjoyment. Nowadays many people grow small lemons in pots at home, but lemon trees sometimes run into problems too, such as leaf drop, so do you know why potted lemon tree leaves drop? Why? Below, the editor introduces the causes and solutions for lemon tree leaf drop:
1. A newly bought potted plant goes into a death-like state
Experienced flower growers all know that many newly planted flowers will go into a death-like state once, just to different degrees. If the leaves of the lemon tree you bought fall off as soon as your hand touches them, there is no need to panic, because this is the plant's survival instinct, just a false death, so do not worry. Of course, if the leaves dry up and turn scorched yellow without falling off, then it is probably really not good.
2. Overwatering and soil alkalinization
Too much water has been given, and the soil may be somewhat compacted and not breathable. Water less appropriately and loosen the soil. If you are in the north, the soil may be highly alkaline, so you can water with a moderate amount of ferrous sulfate to increase acidity (ask the flower shop for the specific ratio with water). Pay attention to changing the soil, and when watering, be careful not to let water accumulate; water only after the potting soil has dried out, and spray more water on the leaves and trunk to stimulate growth.
3. Root rot causing leaf drop
Root rot is often caused by too much water accumulating in the pot or by overly concentrated fertilizer. Remember to rub off the flower buds, cut away the rotten roots, and afterward pay attention to drainage. If too much of the root system has rotted, the plant very likely cannot be saved.
4. Red spider mite damage
Check whether the lemon tree is being damaged by red spider mites. If so, remember to spray pesticide. Before spraying, clear away all the fallen yellow leaves from the lemon tree's pot, loosen the soil frequently, and place the potted lemon tree in a spot with ample light.
[Warm reminder] To prevent leaf drop in potted lemon trees from affecting fruiting, in daily management work, never water sometimes too much and sometimes too little, and pay attention to controlling fertilizer.
Tips for caring for potted lemon trees:
1. After the lemon blooms, besides applying a light fertilizer once a week, you must also thin the flowers and fruits. Before the flowers open, first thin out some of the flower buds; after the flowers fade and the fruit has set, to reduce nutrient consumption, thin out some young fruits in improper positions.
2. During the fruit's growth period, if there is sufficient fertilizer and water and the plant's nutritional condition is good, some branches will sprout new shoots, and the growth of new shoots will inevitably divert some nutrients and affect the fruit's growth. To protect the fruit, promptly rub off the new shoots that grow out.
3. When the fruit turns yellow and ripe, stop fertilizing and reduce watering, keeping the soil moist and slightly on the dry side. If you continue to give too much fertilizer and water, the fruit will ripen prematurely and drop early, shortening the ornamental period.
4. Lemons like fertilizer, so usually apply more light fertilizer. Apply a decomposed liquid fertilizer once before the plant sprouts, then apply a nitrogen-based liquid fertilizer once every 7~10 days to encourage more branches and leaves and more spring shoots.
5. After each pinching, fertilize promptly to encourage the branches to mature earlier. During the lemon's growth period, you can sprinkle some cake fertilizer on the pot surface so that each watering carries some fertilizer into the soil, enhancing fertility. After autumn begins, reduce fertilizing to avoid excessive plant nutrition and the promotion of autumn shoots, which compete with the fruit for nutrients and cause fruit drop.
6. Because potted lemons have little potting soil, the nutrient supply is very limited. After many years, the soil's fertility becomes lacking, and the lemon will weaken year by year, blooming little and bearing little fruit. To keep the lemon blooming and fruiting year after year, you must repot it.
7. The best time for repotting is half a month before the lemon sprouts. After repotting, place it in a ventilated, semi-shaded spot, and after a week put it back in its original place for routine care.
