Watering is very important. Water in the morning and evening at dry seasons. Normally keep the soil wet. Use high Nitrogen fertilizer. Organic liquid fertilizer and compost helps to a better growth. As most of the beautiful leafed plants, Aglaonema also love the shade. Give 50-60% shade from a shade net or give a natural shade.
Some insects, caterpillars, snails may damage leaves. Remove by hand or wash away using water if the hazard is not much bigger. Use less poisoned insecticide when needed. If there is any patches on leaves, it is because of fungi. Use fungicide for this. Use fungicide or insecticide in the morning. Wash the applied chemicals away in the next day. Apply 7 days after first application.
Crops can be collected within 1-2 months. Next crop can get after 3-4 months. Second crop is more larger because 2-4 shoots have arisen from the the previously pruned location. Application of fertilizer after every crop collecting is very important.
