Thanks for your response to my earlier question. What kind of soil, how often should I water the mango tree. I managed to grow the mango tree from pit, however I could not keep it healthy and alive. Leaves turned brown on edges and tips. Same as my Avocado trees. Thanks. Tui

The most common problem with growing mango seedlings is keeping the humdity level high. Since these plants are from the tropics they appreciate warm temperatures and high humidity. They also like moist soil - but it must drain well. If it remains soggy it can suffocate the roots. Try setting the container on a pebble filled tray in which you keep a little water. As the water evaporates it will increase humidity around the plant. Just be sure the container is not actually sitting in the water or the roots will become soggy. Browning leaf tips are often a sign of salt burn, caused by a salt build up in the soil. Salts in the water and in fertilizer build up over time. Browning usually occurs on the old leaves first. This excess salt accumulates in the leaf edges, where it kills the tissue and the leaf dries out and turns brown. At least once a month, water deeply enough to "leach" or push salts well below the root zone. Frequent, light "sprinklings" allow salts to accumulate in the top layers of soil, where the roots are, which is bad news. Similar symptoms occur when too much fertilizer has been applied. Always water plants thoroughly before and after applying fertilizer to help prevent burn. Hope this information is helpful.
