Nutmeg is mainly found in all tropical regions like Maluku Spice Islands and West Indies Islands. It is also widely grown in Madagascar, India, California and Brazil. It is hardy to US zone 10 and 11.

Soil for Planting

Nutmeg prefers a well drained soil; hence using a combination of soil, perlite and sand will be beneficial for the plant. It will provide a good drainage capacity to the soil. Water logging may cause the roots of the Nutmeg plant to rot. It prefers an organic rich soil with a pH level of 6 to 7.


The root balls of the plants are used to propagate the Nutmeg tree. Before planting the root balls, the soil should be mixed well, up to 12 inches with 2 to 4 inches of rotted manure. Dig a hole twice or thrice bigger than the root ball to place it perfectly inside. The holes should be placed in a gap of 40 to 50 feet far from other cultivation or buildings. The root ball should be placed in the soil, but the top part of the root ball, around 1 inch should be protruding outside the soil. Water it thoroughly and wait for the water to drain while adding soil part by part to the hole. Provide 1 to 2 inches of mulch to retain the moisture in the soil.


Water is essential for the Nutmeg plant to grow, especially during the young period.  Except in the rainy period, the plant should be supplied with adequate water. Lightly soak while watering the soil and let the soil dry up to 2 inches completely before the next irrigation.

Temperature and Humidity

Nutmeg prefers a tropical climate and a temperature of about 77 to 95 degree F. But in the first 3 to 4 years, it should be protected from direct sun; after that, it will require full sun to thrive.


The seeds of Nutmeg can be harvested around 3 times a year. The seeds are inside the fruit; hence to start processing, first, the outer cover should be removed and then the aril, in a golden-brown color, covering the red seed should be carefully peeled out. After drying under the sun, the aerial is commercially sold as a spice known as “mace” that is available in a strip or powdered form. The kernel is also dried for a long period till the outer part breaks off and the whole Nutmeg, as a single piece, can be acquired which is used as a spice. Before using, the nut is washed in a lime solution to prevent from insect attack and germination of seeds.
