The Kaffir lime tree (Citrus hystrix) is often cultivated to be used in different Asian cuisines. It gives a sour, tangy taste to meals. However, the green, uneven peel of Kaffir limes make a dish of citrus fruits a little more tantalizing. This tree requires plenty of sunlight, adequate amounts of water, and quality soil to maintain its health. A fertilizer with lots of nitrogen is a prerequisite to support the growth of fruit and flowers. Manure pellets and slow-release fertilizers deliver the ideal nutrients to the Kaffir lime tree.

Kaffir Lime Leaves

Also known as Makrut lime, Leech lime or Thai lime, this lime is a variety grown mainly for its aromatic leaves rather than the fruit. The dark, glossy leaves look like two separate leaves joined together. Mature fruit are yellow and bumpy and they have many seeds. They are usually harvested when still green. Juice and oils from the fruit are used in shampoos, cleansers and air fresheners.

About Kaffir Lime Trees

These lime trees are small with large sharp thorns. They are similar in size to a Western lime and the fruit is dark green with a bumpy surface. They prefer tropical conditions but can be grown in cold climates if protected from cool winds and given lots of sunshine.

Planting a Kaffir Lime Tree

The Kaffir lime tree grows well in pots. Though it can thrive outdoors, it is more appropriate for indoors. If you live in an extremely cold area, plant these trees in pots so that you can move them inside conveniently. Use a container that allows proper drainage.

Selecting a Location

Before planting your tree, pick a location that receives maximum sunlight. After all, this dwarf citrus tree may not bloom to its absolute potential in a shaded area. These trees can often grow as high as eight or ten feet, thus it is imperative to choose a spot that can accommodate your lime tree easily.

Time to Get Started

Use a spade to make a hole in the soil. This hole should nearly be twice the thickness of the root ball of your tree. Make sure to use well-drained soil to plant your tree. Place high-quality organic material or compost into the hole. Add fertilizer or soil amendments, if required. You can help the roots expand to the right level by arranging the walls of the hole with your spade.

Positioning Your Kaffir Lime Tree

Arrange the root ball of the tree in the hole. Use a spade to fill the hole with the soil. Flatten the surface to remove any possible air pockets. Spread enough soil around the stem such that this area doesn’t collect water.

Watering the Tree

Provide water to your newly-planted tree. Don’t provide too much water as it can cause root damage. If you’ve planted your tree in well-drained soil, make a basin around its perimeter so that water can run efficiently.

Fertilization Techniques

Noticing yellow leaves on your lime tree? This may be an indication of a deficiency of fertilizer. Implementation of proper, effective fertilization strategies can provide you with fully grown, juicy limes.

Spreading Compost Pellets

Once you’ve planted your tree, intersperse sheep or chicken compost pellets near its base. Spread these pellets to the drip line. It is important to leave enough space between the tree’s stem and pellets. When you water the plant, the pellets gradually start releasing nitrogen into the soil.

Applying Granular Fertilizer

Apply a grainy, slow-release fertilizer in spring as well as at the starting and end of the summer season. If your tree is around three years old, spread enough fertilizer around your tree’s base. You can even spread it beyond the drip line. You may have to use large amounts of fertilizer in case your tree is over three years old.

Get a Rake

Gently mix fertilizer with the soil using a rake. Avoid exerting too much force as it can damage thin roots.

Post-Fertilizing Watering

Once you’ve fertilized the Kaffir lime tree, give it almost one inch of water.

Care for Your Kaffir Lime Tree

Though Kaffir lime trees are likely to thrive in almost any kind of conditions, it is important to fulfill certain lime tree care requirements to ensure their optimal development.

Sun, Soil, Water – A Few Prerequisites

Kaffir limes grow well in well-drained, moist soil. If your tree is planted indoors, set it close to a sunny window. Provide them with adequate amounts of water during the growing periods. Since excessive water can damage its roots, it is better to let the soil dry out before you water your plant once again.

Protection From Frost

Kaffir lime trees need to be protected from harsh, cold climates. If your tree is planted outside, bring it inside the house during winter.

Efficient lime tree care can help you get a fully-developed, healthy, and sweet-smelling Kaffir lime tree.

What is Wrong with my Lemon Tree? Expert Answers to Top Asked Questions

‘What is wrong with my lemon tree?’ is one of the most common asked questions on gardening websites and gardening talkback radio shows. One of the difficulties of growing a lemon tree, orange tree, lime tree or other citrus tree is that there are many insect or animal pests, various diseases affecting the plant, stem, leaves or fruit, and disorders such as split fruit skins and nutritional deficiencies shown when a mineral deficiency is present in the soil.

This article is devoted to answering some of the most pressing citrus tree questions gardeners we got recently.

Why is my orange tree is not producing fruit?

It is most likely that your orange tree needs fertiliser. Citrus trees require feeding on a regular basis in order to grow well. Feed your tree with a balanced citrus fertiliser every couple of weeks and see if the tree improves. If you live in a cold climate it may be better if you overwinter your tree in a warm greenhouse.

Some of the fruit on my lemon tree have split. Why has this happened?

When citrus fruit split and inside flesh is exposed it can be due to lack of nutrients such as copper and calcium, moisture stress, frost and general health of the tree. This often happens when a tree receives a sudden soaking of water particularly after a long dry spell. Citrus trees require plenty of water while the fruit is developing, so ensure that the tree receives sufficient watering. Good nutrition, and application of lime around the tree every few years will help prevent fruit splitting. If soil is alkaline, add gypsum rather than lime.

The leaves on my lemon tree are covered with oval brown shells and sticky black substance. How can I get rid of this?

This sounds like scale insects and sooty mold. The scale insects feed on new growth by sucking the sap and exude a sticky, sugar substance called honeydew. This accumulates on the leaves and feeds the black mold. If left untreated, the insects and mold weaken your tree. If you control the insects you will stop the mold. To do this, spray the tree with pest oil every 6 weeks until the infestation clears.

Some of the new leaves on my lime tree have silvery lines on them and they have become curled and distorted. What is causing this and what can I do?

This is caused by the citrus leaf miner insect. These minute insects feed by tunnelling their way through the leaves. They do not usually cause a problem for large trees but it is best to treat younger trees. Prune off the infected growth and then spray the tree with a pest oil every 3 weeks during summer and autumn, making sure to cover the top and underside of the leaves.

Last year, my mandarin tree gave me a huge crop but this year there is hardly any fruit at all. Why might this be happening?

Some citrus varieties tend to bear fruit well one year and little or no fruit the following year. This is also referred to as biennial bearing habits’. Varieties such as Valencia oranges, mandarins and kumquats are alterative. The condition may be influenced by factors such as nutrition and water supply. To reinstate regular bearing of fruit, prune during the ‘on’ year when a large crop is expected and ensure good feeding and watering and you may receive a more regular harvest.

There are several large lumps on my lemon tree’s branches. What is causing this and what can I do?

The citrus gall wasp insect has caused the swelling on your branches. It attacks all citrus, but lemons, grapefruit and the Rough lemon suffer most. The wasp is only about 2mm long and shiny black in color. It lays eggs in soft new shoots and as the hatching larvae feed, they cause the infected tissue to swell gall. In spring, adult wasps emerge from the gall. Galling reduces tree growth, and when new shoots become galled, leaf and fruit production is severely affected. Cut off the galls and destroy them by the end of winter before the wasps emerge in spring and lay eggs in the new shoots.
