Mango, popularly known as the king of fruit, belongs to Anacardeaceae family of trees. Taste, flavor and fragrance of mango is very characteristic to the same. Mango was originated in India. Climatic requirements Mango tree is well adopted to tropical and subtropical environmental conditions. It can be cultivated until up to 1300 m above mean sea level. However, commercial cultivations are limited to areas below 600 m above mean sea level. Optimum temperature for mango cultivation is 27-30C. Mango is successfully cultivated in areas where annual rainfall range from 500-2500 mm. For a successful crop, most important thing is the distribution of rainfall rather than the amount. A dry period of 3-4 months is an essential prerequisite for successful flowering of mango. Rains at flowering may affect yield due to pollen wash off. Soil Mango can be cultivated in a wide range of soil conditions. A well drained soil with 2 M depth is the best. Soil pH must be 5.5-6.5. Soils with high clay content or with frequent water logging is not suitable for successful cultivation of mango. At first, remove the husk of the seed. Make a small cut at the distal end of the seed and pull the husk away to get the seed inside without any damage to it. When the cut is made at the distal end of the seed with husk, even if it cuts the seed inside, it does not damage the embryo. Extracted seeds may have mango weevils inside. When such seeds are planted, whole seed may be destroyed. Therefore, dip the seeds in an insecticide solution such as 'Dimethoate' before planting for a few minutes. Use of fungicides such as 'Captan' at this time is helpful to protect the seeds from fungal infections at the nursery. Seeds treated with insecticide and fungicide solution must be planted in a sandy seed bed. For the seed bed, use a 15-20 cm thick layer of sand. Sand beds must be laid out in a place with slight shade. However, never under trees such as mango or avocado. Then it is easy to protect the seedlings from certain fungal diseases. In the sand bed plant seeds in a row spaced 15-20 cm apart. Curved side of the seed must be downward at planting. Spacing of 2-3 cm is allowed between two seeds in a row. After seeding, keep the sand bed moist at all times. Seeds germinate and seedlings emerge 10-14 days after planting. About three weeks after emergence, seedlings are suitable for transplanting in polyethylene pots or any other secondary nursery. If a media such as coir dust is used for germination of seeds, care must be taken to maintain the appropriate moisture level. At high moisture levels, seedling may be infected with fungal diseases. Plants hardened in the seed bed may be transferred to polyethylene pots filled with a suitable media. Else plants may be transplanted well prepared secondary nursery.

Okay, I am going to repot it tonight. When I get it out of the pot, should I remove the rotted roots? Cut them off till I hit healthy roots? What about watering the newly potted tree. I am thinking of putting it in either a smaller pot, or using the same pot but half the soil amount. I have seen this befor with potted fruit trees. Tammy did this with one of her mangoes and I believe CH3rri also did it. What do you guys think? I am hoping it is not too late but if I lose one out of three, that is not too bad. The rest of my tropicals are good except two citrus have spider mites now but I have been spraying with soapy water. The blood orange seems the worse off so far. It is dropping leaves but the keylime is not losing any leaves. Andrew

Is it 'damping off?'

persoanlly, i would take it out, and wash it off in hydrogen peroxide. you can use the stuff from the store look on the bottle and make sure of the percentage it should be between 2 and 4 % i would cut that in 1/4 at least (dilute 1 part HP with 4 or 5 parts water) use an old toothbrush, or something to gently rub the fungus off let is sit in solution for 2-3 mins rinse well... re-plant
