Aglaonema Care Instructions
Many people ask us for the proper care of the Aglaonema plant – commonly known as the Chinese Evergreen. By following these instructions, you should have no problem keeping your Aglaonema not only surviving, but thriving for years to come. The Aglaonema is one of the most popular indoor plants used in homes, offices and interior landscapes due to its attractive appearance and tolerance of low light and poor air circulation. They are on NASA’s list of clean air plants because they help filter the air of harmful chemicals. It is recommended to use one plant per 100 square feet of living space to help filter chemicals such as formaldehyde and benzene from the air. Aglaonemas are native to tropical and sub-tropical regions of Asia and are in the family Araceae which is closely related to the Spathiphyllum and Philodendron.
Over the years, Aglaonema have been hybridized and bred into a vast array of colors, patterns and leaf shapes. Some of the most common include BJ Freeman, Calypso, Maria, Candy Cane, Cutlass, Diamond Bay, Silver Bay, Emerald Bay, Gold Dust, Dionne, Jewel Of India, Jubilee, Simplex, Spring Snow, Peacock, Lumina, Moonlight Bay, Romeo and Silverado. There are dozens more! There seems to be an endless choice of patterns and colors – even varieties that have pinks and reds in the leaves and stems.
Aglaonema do best in well-lit locations such as a window sill that has an Eastern exposure. Bright but indirect sunlight is optimal. Be careful not to put your Aglaonema in full sun because in many cases the plant will burn and the leaves will be damaged in a similar way that people get sunburn. If you have less than optimal lighting available, do not worry. Many varieties of Aglaonema will tolerate very low light. In most cases, artificial lighting such as in a windowless office proves enough for this tough plant. Some varieties tend to do better than others in low light. For a poorly lit area, try Aglaonema Simplex. From our experience it is one of the best Aglaonema for a challenging situation.
The Aglaonema is one of the best house plants because it prefers the same temperatures that many homes are kept at on a daily basis. Night time temperatures in the lower 60’s and day time temperatures in the 70’s are ideal. Keep in mind that although your home or office are kept at these average temperatures, other factors may play a part in your plant being too hot or cold. Make sure that your Aglaonema is not directly affected by a heating or air conditioner vent. The direct cold or hot air will surely damage your plant. You also want to keep an eye on the window if you place your plant in one. On very cold days, the glass will transfer the cold – and if the leaves from your Aglaonema are pressed against the glass, they will become damaged. It is never a good idea to have your Aglaonema up against any window or wall. You will also want to avoid any drafts in colder climates. A cold gust of wind from being placed near a door or window that opens could also damage your plant.
The most important thing to keep in mind when watering Aglaonema are that you want to avoid creating a situation that promotes root rot. In our homes and offices, we keep Aglaonema in a light, well-draining soil. They prefer to be kept moist but not wet to the point where they never dry out. There is not specific amount or frequency of water that we can suggest because the lighting, temperature and evaporation rates differ in every home. You will need to develop a feel for the proper amount of water. Try to keep an even amount of moisture, not letting your plant stay soaking wet and not allowing it to completely dry out. Do not let water accumulate in the crown or cups that the leaves. Moderation is key. Any planter that allows for evaporation, air flow and water drainage works well. Once you develop the “feel” for watering, you will be able to judge when to water by picking up the plant. The heavier the plant feels, the more moisture there is in the growing medium. If the plant is too large to lift, a water meter is well worth the investment.
Are Your Plants Leaf Tips Turning Brown?
A common problem with Aglaonema and almost all indoor houseplants is what we call “tipping” or simply the tips of the leaves drying out and turning brown. This can be caused by a number of factors including over-watering, chemical burn from too much fertilizer, Root rot and dry stagnant air. Probably the most common reason your plant is tipping could be in the tap water. Tap water contains salts, chlorine, minerals and fluoride – all of which can build up in the soil of your plant causing the tips of the leaves to burn and turn brown. One way you can reduce this is to use a water filtration system. If you do not have a filtration system available, leaving he water in an open container overnight before using can help relieve some of the chlorine.
Do house plant fertilizers work? Definitely. Aglaonema, like every other living thing need a source of energy. The plants take in their nutrients from the water and potting medium they are planted in. That medium only holds so much, and when the nutrients are depleted, fertilizer is the only source left. People who grow house plants without repotting and fertilizing regularly are essentially starving the plants and holding them back from their full potential. There are many different fertilizers on the market and they come in many forms. There are water soluble fertilizers, ready to use liquid, liquid concentrate, fertilizer spikes, time release granules and many others. Which orchid fertilizer works best? That is up for you to decide. We prefer a ready to use liquid simply for the convenience of use. We also dilute the fertilizer and use every time we water so there is a constant stream of nutrients being fed to the plants.
