African violets are among the easiest high-impact houseplants you can grow. Once you master a few basic plant care steps, you can have blooming flowers year-round.
1) Light - We all know that plants need light to grow, so make sure you provide adequate light. An east or west window sill works best. In the summer even a north-facing window can work well for African violets. If you don't have adequate light, flourescent or specialized plant lighting also works well. The light in south-facing windows is usually too intense for violets and can burn leaves and dry out the soil too quickly.
If you want plants on tables or other areas of the house without adequate sun it's okay to rotate plants around for color every week or so.
Make sure to protect plants from drafts from open windows and doors.
2) Water and Humidity - African violets sulk when they get thirsty, so plan to monitor the moisture level of the soil daily. When the soil feels dry to the touch, water with tepid--never cold--water. Avoid getting leaves wet when watering to prevent discoloration or spotting of the leaves.
You can water from the top until a small amount of water flows from the bottom drainage hole. If you water from the bottom, make sure the plant isn't left standing in water for more than a few minutes. There are also specialized African violet pots that have a wicking system for automatic watering in case you're the forgetful type.
If you really want to give your plants a boost, sit them on a humidity tray. Any waterproof tray filled with rocks or pebbles and filled with water works well. Just make sure that the water does not touch the bottom of the pot and get the roots soggy.
3) Food - Many growers recommend a weak solution of specialized African violet food whenever you water. Some fertilizers are meant to be given on a routine of every two to four weeks. Make sure you follow the instructions on whatever food you use.
4) Environment - Violet leaves are covered with tiny little “hairs” that can trap dust and animal hair. Just use a soft-bristled paintbrush to brush off dust or debris.
