Growing Neem Sprouts

 In Growing Guides

A native of India, neem is an extraordinarily hardy tree that thrives in ecosystems ranging from the Sahara Desert to the wet salty environment of the Florida Keys. The only pests known to harm it are directly related to overwatering: slugs (which are mollusks not insects) and several strains of root rot.

In Florida and other tropical climates, neem quickly becomes a valuable shade tree, growing up to eight feet per year under optimum conditions. In colder climates, neem trees can easily be grown in large pots as highly decorative houseplants, repelling pests such as scale and spider mites that can kill common indoor plants like ficus or palm trees.

The single most important thing you can do to ensure the success of these seedlings is to PLANT THEM NOW! Like many tropical trees that thrive in regions where winter is not an issue – but voracious insects are – neem seeds are in a race against time the minute they ripen. They’re notoriously difficult to germinate, so we sell sprouts as well as seeds, but neem sprouts must be transplanted as soon as possible.

If the seedlings arrive with entwined roots, soak the root ball in water. That will allow the dirt to fall off and make it easier to separate the individual plants. Poke a hole in the soil with your finger or another tool, and place the seedling in the hole root down. Tamp down the soil around the roots to ensure good contact..


  • Do not use potting soil with “water management” polymers – it can hold so much water that your neem tree drowns.
  • Do not use soil from your yard or compost pile unless you’re an expert gardener and know exactly what you’re doing.
  • Do not use “garden” soil instead of potting soil. It is not typically sterile and often holds more water than a potting soil.

Water well, but don’t water again until the soil is dry at least an inch deep. The easiest way to kill a neem seedling – or tree – is to overwater. If a neem tree wilts while the soil is damp, it’s already has too much water. Try to put it in a spot where it gets morning but not afternoon sun, and let the soil completely dry before watering again.

For optimum growth, start your seeds in small pots, but transplant into larger pots as they grow, since they’re like goldfish and will only grow as large as their pots allow.  We use a balanced organic fertilizer ( during their growing season and occasionally supplement with dilute fish emulsion or kelp spray. They’re happiest in as much sun as you can give them, but they prefer shelter from high winds and heavy rain until they have had time to develop a good root system.

You’ll also need to bring your seedlings inside before temperatures drop below about 35 degrees. Put them in your sunniest window and provide supplemental light in the evening. Like many tropical plants, neem are day-length sensitive and will stop growing in short winter days. It doesn’t take much to fool them into thinking it’s still summer though — a near-by living room lamp is fine.

As your sprouts become neem seedlings and trees, check back for directions on how and when to transplant them.
