Alma trees--better known as Indian Gooseberries--are typically grown in subtropical climates. They are native to India and bear small fruit that is rich in vitamin C and are used in many herbal and natural medicines. While Amla trees do well on their own, with a little bit of care, they can thrive and bear larger fruits.
Water Amla trees every two weeks during the summer months. If you live where there are monsoon rains, in October, November and December, water your tree with about 25 to 30 liters (six to seven gallons) of water using a drip system, if possible. Drip systems drip water slowly to your tree. Drip systems can be purchased or built (see Resources). Generally, you do not need to water Amla other times of the year.
Fertilize Amla trees if the fruits are not as large as you would prefer. Use an organic manure such as Green Manure or Vermi-Compost. Fertilize twice a year in January or February and again in August. Follow manufacturer dosing instructions based on the age of your tree and type of soil. Water after fertilizing.
Harvest when the fruits are greenish-yellow, usually beginning in February. Hand pick as many of the fruits as possible so you do not damage your tree. Use a ladder for higher areas, if possible, but use a pole and hook carefully if desired.
