- What causes lime tree leaf drop?
- What should a farmer do when they are facing the challenge of lime tree leaf drop.
Lime trees, like all citrus trees, are evergreen trees. Naturally, when a lime sheds its leaves, it is a signal of a serious underlying health issue. It is unnatural for a lime tree leaves to drop.
To decipher the reason for your lime tree leaf drop, you have to retrace your activities to deduce what triggered the leaf drop.
Citrus trees are sensitive and often respond to problems by shedding leaves. If a farmer can find the root cause in time and fix it, the tree may be saved.
What causes lime tree leaf drop
There are several reasons why lime tree leaves may fall off. The most common reasons are discussed below.
1. Shock
When ambient environmental conditions change abruptly, the lime tree will be set into a shock and respond by shedding leaves.
If, for instance, you are moving the lime inside in preparation for winter, if you get up one day and bring the plant in from the outside, the sharp change in conditions from hot fall to cool air daft inside your warm will shock the lime plant.
Due to the stress from environmental conditions, the lime tree may respond by dropping leaves out of shock.
2. Insufficient soil nutrients
When a plant runs short of food from the growing medium, the plant may respond by shedding leaves to save the food that would have otherwise gone into the foliage’s maintenance.
Suppose you haven’t fertilized the heavy feeding lime in a while and notice lime tree fall. In that case, the chances are that the plant is shedding due to insufficient nourishment from the soil.
3. Over-watering
While watering is essential for lime trees, overwatering may cause root rot and other cascading damages to your plant like root rot.
If the roots of a plant are damaged, there is no way the plant will absorb nutrients from the soil, and as a result, the shoot system will starve, which, as previously mentioned, will cause leaf drop.
4. Poor soil drainage
Lime trees cannot stand stagnant water. If the drainage is poor may be due to the soil type you planted in or the kind of growing pot you used to grow your lime tree or other factors that are causing the soil to be poor drainage.
When roots of the tree sit in water, they have a tendency to develop root rot, which in turn results in the lemon tree dropping leaves. Mulch around the root area, minimize irrigation, plant in well-draining soil, and keep grass away from the tree’s base to avoid root rot and its accompanying problems.
5. Pests and diseases
Some pests and disease infestations can cause lime leaves lime tree leaf drop. Scale insects and other sap-feeding parasites can cause malnutrition to the shoots resulting in nutrient deficiencies and leaf drop.
Also, scale insects can cause sooty mold to grow on the leaf surface, which reduces the photosynthesis rate and can end in leaf death. When lime tree leaves die or become damaged, they fall off the tree.
What to do when you are experiencing lime tree leaf drop
What you do when lime tree leaves fall off depends on what is causing the leaf drop in the first place. Do not panic. I know the majority of farmers are set into a panic after their lime tree loses leaves.
Limes can recover from leaf drop even if all the foliage is lost. All you need to as a farmer is to water adequately, fertilize, and trust the process.
Listed below are things to do when your lime tree leaves drop.
1. Water adequately
When lime leaves, many gardeners may be set into a panic and tend to overwater or stop watering altogether. The key to keeping the lime tree alive even when the leaves fall off is to water the lime trees enough.
Just because too much watering is what killed the leaves doesn’t mean that you should stop watering. You can increase the drainage to remove the stagnant water and then go on to water adequately as you ought to.
2. Fertilize
Sometimes lime tree leaves drop because of lack of sufficient nutrition from the soil. A gardener needs to fertilize to feed your lime tree, especially after it has dropped leaves.
It is crucial to fertilize your lime tree with a nitrogen-rich fertilizer enriched with trace elements to revive your lime tree. It is better to use a slow-release fertilizer.
3. Control pests and treat diseases
One of the reasons that lime tree leaves may drop is because of disease and pest attack. If you can control the pests and diseases, you can reduce and even reverse the leaf drop.
Controlling pests and diseases is using horticultural spray like neem seed oil, pesticide, and insecticide. Pests and diseases can be easier controlled if you are caught early, this means that you have to monitor the lime plant often.
4. Prune the dead branches
After the lime tree leaves drop, the plant may also have damaged branches and tips. Leaving these on the plant means that the plant will be wasting energy on the damaged parts even though they might die anyway.
The best thing to do for the plant, in this case, is to prune the dead parts away to encourage new leaf and healthier leaves.
5. Whitewash exposed bark
When a lime tree loses foliage, the trunk and branches are left exposed. If you leave in a sunny climate, the tree will also be exposed to sunburn.
You can avoid sunburn by using organic whitewash on the exposed branches and trunk.
Lime tree leaves dropping; lime tree leaf drop.
Ideally, limes aren’t meant to lose their leaves. When your lime tree leaves are dropping, it might become easy for you to panic as a farmer. You may be wondering what could have been done to prevent the leaf drop.
Is it possible to prevent lime tree leaves from dropping? Yes, listed below are a few tips to prevent lime tree leaves from dropping.
1. Invest in a moisture meter
Sometimes it is difficult to estimate soil dryness and determine when to water lime trees. In such cases, it would save you so much if you had a moisture meter or gauge.
Alternatively, suppose you can’t afford the moisture meter. In that case, you could use a wooden skewer to determine the water moisture in the soil before watering. You insert the skewer into the soil, and depending on how the soil attaches to the skewer, you determine whether you need to add water or not.
The main problem you are avoiding is overwatering. Watering isn’t as easy as 1-2 times a week because different factors affect the soil moisture. A farmer can easily go wrong by following the once to twice watering rule even though it is the recommended watering rate.
To avoid overwatering, which is detrimental to the plant, a farmer needs to rely on more accurate soil moisture measurements to determine whether or not to water.
2. Fertilize sufficiently to prevent lime tree leaf drop
This is particularly important if you are growing your limes in pots because all the plants’ nutrition is what you give them. You can use organic fertilizer or synthetic or micronutrient soil modifiers.
It is important to supplement your soil’s nutrient content for your lime to survive and revive from the lime tree leaf drop.
3. Acclimate, don’t just transfer plant to avoid lime tree leaf drop
While it is best to bring lime trees during the winter to avoid frost damage, you mustn’t abruptly bring the plant immediately.
A week or so before you plan to bring the plants in, first move them to a shady spot. An area is similar to the conditions inside but not so different from outside where they have been. You could put them on a balcony or patio.
After the plant has been in the semi-inside climate for a week, you can now take in. Gradually changing the environment prevents the plant from being shocked by abrupt sharp changes, leading to lime tree leaf drop.
Acclimatizing the plant before transferring will reduce the plant’s stress due to changes in ambient conditions of temperature, light intensity, and air currents.
Will lime tree leaves grow back after lime tree leaf drop.
Trees are resistant, and even if all the leaves fall off, there is still hope. With a little extra TLC and time, lime tree leaves will grow back better, rejuvenated, and vibrant. Look below for ways to care for your lime tree after leaf drop to ensure better new leaf growth.
The majority of times, leaves grow back. I know that a naked tree is heartbreaking, especially when you have put in effort in caring for the tree only for the leaves to fall off. But unless severe root or trunk damage is the cause of the leaf drop, the leaves always grow back, which has to be addressed.
Care for lime trees post-leaf drop
1. Focus on micro-nutrients to help your tree recover from lime tree leaf drop
Nitrogen, phosphorus, and potassium are essential for plant growth but so are the remaining 10 elements even though they are required in small quantities. Magnesium is particularly important in chlorophyll formation. Potassium in the uptake of other nutrients copper and molybdenum are cofactors and coenzymes.
Micronutrients are important, and a lack of them may be nearly as bad as a lack of insufficient nutrients. So, don’t ignore micro-nutrients because the plant will require them for plant revival and revitalization.
2. Focus on pest and disease prevention to control lime tree leaf drop
Pests and diseases can make the problems associated with leaf drop worse. After lime leaves drop, it is important to show the lime tree some TLC to avoid further infection, resulting in death.
You can use whitewash with pest repellent properties and invest in organic pest control mechanisms like neem oil to protect your plant from infestation by pests and disease.
Problems associated with lime tree leaves besides lime tree leaf drop
Besides leaf drop, lime trees experience other leaf problems; it is important to realize that some of the leaf problems precede and even cause leaf drop.
The other common problems associated with lime tree leaves are lime tree leaf curling and leaves turning yellow or brown. The most common reasons are lack of nitrogen and micronutrients in the soil, overwatering, and sap-feeding pest infestation.
Like with the drop, the best way to recover from lime leaves turning yellow is to address the reasons behind the leaves curling, turning yellow or brown. That includes fertilizing, watering the limes just enough, and pest control.
FAQs
There are various reasons why leaves are falling off your lime tree; however, the most common causes is shock and stress caused by fluctuating temperatures and environmental conditions.
Lime trees are ‘temperamental,’ and relocating them triggers a panic reaction from the plant, usually shedding leaves. By moving the tree to sharp and abrupt changes in the environment, you shock the tree and as a defense mechanism, the tree starts shedding leaves.
Yes, even though it is unnatural due to external traces and stimuli like temperature changes, disease, and overwatering, lime trees sometimes shed their leaves.
How you revive your lime tree depends on why your tree became sloppy, dull, or u productive. The most common ways farmers revitalize their lime trees are by fertilizing the soil, watering adequately, and pruning the skeleton to encourage new growth of healthier shoots.
On average, water once to twice a week. Limes do not like dry soil, but neither can they stand soggy soil. Watering once to twice a week should suffice unless you live in dry, hot weather, in which case you might have to water daily.
Final thoughts
Lime tree drop can be scary but relax; it’s not the end because limes are stronger than you think. With extra TLC, your lime can and will survive lime tree drop and be healthy again.
