How to Care for a Tamarind Tree?
The tamarind tree, originating from tropical Africa, is typically known for its edible fruit used in recipes. The tree reaches heights up to 80 feet and grows best in warm climates. Temperatures below 28 degrees Fahrenheit can damage the tree and cannot be endured often. Dry weather is needed to ensure proper development of the tree's fruit pods. The tamarind tree does not grow well in containers, as its root system becomes too large. If you do not live in a suitable area, do not attempt to grow the tamarind tree.
Select an outdoor location that receives at least six hours of direct sun per day and that has well-drained soil. Dig a hole twice the size of the tamarind sapling's root ball. Gently remove the pot from the sapling and cut away dead or damaged roots. Slide the root ball into the hole and add soil to keep the tree's trunk above the soil line. Add soil around the root ball to smooth the ground, then water the area thoroughly. If the tamarind tree is already planted in the ground, skip this step.
Spread a 4- to 5-inch-thick layer of mulch around the tamarind tree at the start of each spring. The mulch should extend at least 1 foot past the tree's widest point on all sides. This helps protect the tree's roots and keeps the soil moist, mimicking the effects of a natural forest floor.
Feed the tamarind tree with fertilizer sticks as per the manufacturer's instructions in the beginning of spring. Fertilize young trees with 6-6-3 NPK fertilizer and mature trees with 8-3-9 NPK fertilizer; the numbers represent the amount of nitrogen, phosphorous and potassium within the fertilizer. Most tree nurseries carry suitable fertilizers. Fertilize the tamarind tree once again during mid-summer.
Cut away dead branches with pruning shears on the same days you apply the fertilizer. This keeps the tree healthy and aesthetically pleasing.
