Most houseplants die because they are not watered properly. Houseplants are usually in containers, which are perfect locations for stagnant water, poor aeration, anaerobic bacteria and worst of all, root rot fungi. Indoor gardeners must pay close attention to the correct amount of water to give their plants each day or week. At times when you are away or too busy to water plants, indoor plant watering systems are available to solve the problem.
Plants that are placed in sunny locations must be watered more than plants placed in shady locations, since the sunlight causes the water to evaporate, drying out the soil. Also, the kind of pot you use affects where the plant soil evaporates the most, according to the University of Minnesota. For example, clay pots have water that evaporates more near the sides of the pot.
Water should drain out of the hole at the bottom of the pot into a tray that is emptied out every time the plant is watered. Otherwise, a part of the plant's roots can die, according to the University of Connecticut. While the death of these roots is not catastrophic, the dead roots serve as an entry point for bacteria and fungi that can kill the plant.
The automatic watering system is an indoor irrigation system that provides water for up to 14 plants on a two-week schedule. Water from a container is filtered through hoses that deliver specific amounts of water to the various plants hooked up to this system, according to Plant Care. The amount of water that is released for the plants can be adjusted so that plants with different water needs can all be fed by the same machine. A similar device is called a houseplant sitter. This device rests on the wall and delivers water to plants through tubes, according to 7 Gadgets. It can water up to 20 plants for 40 days.
A much simpler system is the water worm. The water worm is a tube, of which one end is placed in a glass of water and the other is placed near the plant. This solution only works for one plant, but is great when you're going away for a long period of time, according to Host Webs. This watering system can be cumbersome, however, when there are many plants and not very much space.
If a plant gets root rot after all, the plant might be salvageable by digging up the plant and cutting off the blackened roots. If this does not work, the plant and the soil should be removed and disposed of, since they are contaminated with the pathogenic fungal spores. Remove the fungal spores by soaking the plant pot in a diluted bleach solution before planting new plants.
