Your plant requires temperatures between 75-85 degrees Fahrenheit. The lowest temperature your tree can handle is 60 degrees Fahrenheit. no wild temperature fluctuations. High humidity is very important as well as good air circulation, but never expose plant to dry wind/air. Dry air will kill this plant, so maintaining a humid environment is vital. Lots of water but not standing water, you can water every day if drainage is good. never let it dry (it will kill a plant in a day and cacao plant will not recover) Full shade for the first 3 months, then full shade to partial shade. Will tolerate some sun when 4-5 foot tall. Sun will kill this plant. Cacao plant does not need direct sun, filtered sunlight is optimal. Very fertile soil. If planted in pots, I would recommend mixing Pro-Mix BX potting soil (for keeping moisture) mixed with Pro mix HP CC (for good drainage) and with good organic potting soil or very well rotted compost (for fertilizing) 1:1:1. You can also add 1/10 part of sand. Optional- polystyrene beads (not biodegradable) on the bottom of the pot (1-2 inch) Plant it in 5-7 gallon pot when received or a week later and increase the pot size to 10-20 gallon pot in 6-12 months. Many hydroponic fertilizers (organic or not) will work just fine (6:2:8 or similar) Water, rain water or rain water with reduced PH to 6-6-4. Non organic fertilizer (cheap)- miracle grow for acid loving plants – 1/2 tsp in 5 gallon bucket. you can also add Epsom salt 1/4-1/2 tsp in 5 gallons bucket. many growers prefer the organic fertilizer. Lower leaves turn yellow and fall off. It is normal for this plant when nicely growing at the top.
