Red Siam Aglaonema is a very easy plant to care for. It has vibrant green to silver, and red pointed leaves. These vibrant colors are sure to brighten up any room. This plant typically blooms a light greenish-white flower during late summer or early fall. They are native to the humid, shady forests of Asia and New Guinea. 

Best Location For Growing Red Siam Aglaonema

This houseplant appreciates heat, so consider placing it in a warm, humid spot where night temperatures remain above 60 degrees Fahrenheit. Daytime temperatures should be between 75-85 degrees Fahrenheit. This plant is toxic if ingested, so place the plant accordingly. During the summer, this plant performs well outside on a shaded patio or deck. Just bring them inside when fall temperatures begin to drop below 60 F. This plant is hardy in zones 11-12.

Red Siam Aglaonema Sunlight Requirements

This beautiful plant prefers low to medium indirect light. It can adapt to very low light conditions, but the growth will slow considerably. Direct morning sunlight is fine, but avoid exposure to the bright, direct afternoon sunlight, which will burn the leaves. A grow light can be used if ideal indoor conditions are not available.

Red Siam Aglaonema Care

This stunning exotic plant prefers loose, well-drained, porous potting soil. A good soil mixture is one part potting soil, one part peat moss and one part perlite. This plant requires high humidity or frequent misting. It can flourish outside as long as it's not exposed to too much bright, direct sunlight. Red Siam Aglaonema can be propagated by stem cuttings, seeds, or root division. The easy method of propagation is dividing the root ball into two or three sections.

Watering Red Siam Aglaonema

Water this plant when the top 2-3 inches of soil become dry to the touch. One preferred method of successfully watering Red Siam Aglaonema is the drench and dry method.  Allow the plant to dry fairly well and then slowly drench the plant thoroughly. This keeps the roots partially moist but not soggy. If it's a dry environment, daily misting can be done. 

Fertilizing Red Siam Aglaonema

Fertilize this houseplant once per month with a diluted, balanced houseplant fertilizer during spring and summer. During the fall, you may only have to fertilize the plant once, while holding off during the winter. Be careful not to over fertilize this plant as a buildup of mineral salts can cause root burn and brown leaves to form. You can avoid this buildup by flushing the potting soil with water every three months.
