Propagation:

Curry leaf is primarily propagated through seeds. For raising seedlings, properly ripened fruits are collected from high-yielding plants. It is advised to remove the hard outer shell of seed before sowing for faster germination. The seeds are sown either in nursery or polybags filled with a mixture of 1:1:1 sand, soil and farmyard manure. Seeds usually germinate in 3 weeks and One-year-old seedlings are preferred to be planted in the field. It can also be propagated by root suckers. There are a number of root suckers present near its plants. They are removed from the main plant during the rainy season and planted immediately to propagate a new plant. Stem cuttings and plantlets are also used for raising new plants. Regular pruning or picking of leaves is essential to promote the fresh foliage growth.

Soil Preparation for growing curry leaves in backyard:

The soil should be fertile and should have good organic matter. In deep, fertile and light soil transplanting is done directly in small pits. Whereas in poor and hard soil, pits are taken at the size of at least 1.5×1.5×2 ft. length, width, and depth respectively. The pits are dug about six months before planting and left open to weather for few months after which they are filled with well rotten composts and green leaves.

Planting:

when planting a curry plant in your backyard kitchen garden it is recommended to grow your plant directly in the soil surface rather than raising it in the pot or any container because it attains a good height and growth that your container cannot hold up and when growing in pots proper cutting and pruning becomes a headache so let your curry plant grow well on ground and enrich your dining table with lovely aroma and taste.

Manure and fertilizers:

Usually, curry leaf plant is not given inorganic or chemical fertilizer as they affect its aroma which is the key character. But for higher yields, its plant may be given 10kg farmyard manure and NPK @ 60:80:40g/plant/year and some biofertilizers such as manure. The fertilizers may be applied at the onset of the monsoon.

Aftercare and maintenance:

The pit should be irrigated properly if there is no availability of rain. The plant should be irrigated at 3-day intervals at least if there are no rains. The field should be kept weed free by proper rouging. The plants should be trained and pruned to keep a height of about 1m. Their terminal buds are recommended to be removed for encouraging lateral branching. A least of 5–6 branches are kept per plant.

Watering your curry leaf plant:

If proper irrigation facilities are convenient the plants should be regularly irrigated. However, moisture conservation techniques should be adopted both to conserve rainwater or irrigation water when growing plants in a huge area. Mulching is an advantageous practice. At the same time, adequate drainage facilities should be provided. When cultivating curry plant at home you can simply water your plant every alternate day or so because it doesn’t demand much water.

Topping:

Leaves are the economic product of the curry leaf tree. To achieve maximum leaf production the plants are topped first at around 100 cm height. This encourages profuse branching on all sides. Allow them to grow and develop leaves. Then they are again pruned to encourage further branching. After every pruning or topping of branches, an additional dosage of NPK and compost mixture should be applied and irrigated. This will result in profuse growth of leaves. Topping is done in such a way that each plant acquires a good shape allowing all branches and leaves to have adequate sunlight.

Harvesting:

The pruning or topping is also a part of the harvesting of leaves. The leaf quality will decline if the plant is allowed to flower and fruit. So unless seed production is not indented, pruning and harvesting of leaves should be done before flowering. Similarly where there is winter harvesting is done before the leaves start shedding.

At commercial level Harvested leaves are graded, bundled and marketed or sent to processing units for the extraction of oil.

Diseases and Pests:

Luckily, the curry leaf plant is not critically infected by diseases and pests. If required very mild pesticides can be used at least 15 days before harvesting of leaves. If there are chances of incidence a preventive spray of malathion or tobacco decoction, etc could be sprayed. For controlling soil-borne pests and diseases about 1-2 kg of neem cake per plant per year is suggested.

Additional Tips for Growing Curry Leaves in Backyard:

  • Don’t overwater it, especially in winter.
  • Let the soil dry out during water spells as it likes well-drained dry soil.
  • Plant it in a small container and then regularly update the size of the container to the next one as the plant progress its growth which is not a rewarding process.
  • Place it (colder zones) indoors or in a greenhouse in winter.
