The violet is happiest with consistently warm and average temperatures. Try to avoid cold drafts and sudden temperature fluctuations.
The violet is victim to the perplexing definition ‘keep moist, do not allow the soil to get soggy or dry out’. Violets prefer moist soil. So to alleviate the guesswork and frustration, simply purchase a water meter. They are very easy to use and will keep the houseplant happy.
Unlike the rumor, the African violet is averse to having its leaves wet from being watered from the top, but the trick is to dry the leaves off to avoid disease or rot. You may consider using a watering can with a narrow spout or purchase an African violet planter, where the water is absorbed from the holding reservoir.
Fertilize with a balanced soluble food for houseplants or choose a food with specific African violet elements.
Place in a location that provides filtered light and avoid direct sunlight.
If your violet is slow to bloom, it may need extra energy. Increase its light intake or provide fertilizer if the plant has not been fed recently. Also, you can also pinch off the dead blooms to encourage new growth.
