Pour in about 1/2 DL chicken manure pellets and 2 m.sk Epsom salts or 1 DL. Bat Guano and 2 m.sk Neem litter and 2 m.sk Epsom salts, I use the latter of these 2 mixtures.
Fill with soil up to the pot edge. Make a hole in the Earth and put down the plant. Press to easily. Water gently just around the plant. before watering next time feel after so that the soil around the plant has begun to dry up. watering this way they 3 – 4 the first few weeks.

Keep in mind that the plant needs light energy to be able to establish themselves well in the pot so it must get extra lighting now that daylight is insufficient to.
