The Noni tree is a tropical plant filled with wonderful health benefits that come from the fruit. Each fruit contains vitamins such as, Vitamin B & C, Iron, Zinc, Potassium, Magnesium and antioxidants to help boost your immune system and give you more energy. In multiple cultures, the leaves are known to be used while cooking to wrap fish. Seeds can be baked and the fruit itself can be eaten or juiced. Noni trees can be grown anywhere but only planted in the ground for warmer growing zones 10-11. If the temperature drops below 40 degrees, they need to be brought indoors. The trees can reach up to 30 feet tall, and a pollinator is not required for their fruit production.
Choosing a location: If planting outdoors, they prefer to be planted in direct sunlight. About 12 hours of sunlight a day is highly recommended for best growth and fruit production. If planting indoors, they prefer to be placed in a sunny window with Southern exposure so that they have the best growth and fruit.
Planting Directions (in ground): The Noni tree prefers to have a well draining soil. The roots do not like to be wet and can get root rot if they sit in water for a long period of time. If you mix soil, sand and perlite it will allow for proper drainage. Make sure you choose a location that is at least 10 ft away from other trees or shrubs.
1) Dig your hole twice as wide and just as deep as the root ball.
2) Loosen the soil around the hole and the root ball so that the roots can more easily break through.
3) Position roots downwards into the hole and be sure plant is straight.
4) As you backfill the hole, make sure you remove all air pockets by applying water.
5) Water your tree again after planting is complete.
Planting directions (potted): Provide adequate room for root development. The size of the pot will determine the size of your tree.
1) Start out with a pot that is roughly 18-24 inches wide (15-25 gal) and about 20 inches tall.
2) Be sure there are adequate drainage holes. If you use a glazed pot, you won’t need to water them as often as in a terracotta pot due to them being porous.
3) Place the potted tree next to a South facing window for its full sun needs. A grow light may need to be utilized if there is a lack of sun.
Watering: Noni trees are known for their drought tolerance and thriving in hot, arid conditions. When watering Noni trees make sure to lightly soak the soil and then do not water again until the top 2 inches have dried a bit. Mature trees will only need to be watered once (maybe twice) a week. Older trees will require even less water, less frequently. Never saturate your soil with water or root rot can damage or even kill the tree.
Pruning: Young plants can be pruned back after or during the first fruit production. As you prune, it will result in a more bushy plant. If you prune back the vertical branches of mature trees, it helps with the fruit harvest.
Fertilizing: Wild Noni trees have been found to do fine without the addition of fertilizers but for the best fruit yield at the time of harvest, fertilizer is definitely recommended. The trees should be fertilized frequently with small amounts of chicken manure, crushed coral or macadamia nut husks. Another good way to feed the Noni is to introduce a time released 8-3-9 fertilizer formula when watering the tree. Be sure to follow the application directions on the package.
