The Golden Rule to Healthy African violets is "Correct watering is the most important thing you can do for a healthy violet."
In my experience, I have found:
if your violets don't bloom, adjust the amount of light or how you
BUT, if your violets are dying, it is most likely you
need to correct your watering habits or methods.
But half the fun of African violets is the learning, the experiences, and the things you learn!
For my house conditions, and my habits, I have developed some general things which work well for my plants, IF I do them.
I do 3 things to make sure my violets are watered correctly:
1) I use the same soil mix in all my plants: mama leaves, babies, large plants, and even my other houseplants.
2) I use pots of certain sizes for certain sizes of plants:
* Any violet plant that is rapidly putting out new blooms or new roots is planted in a pot that allows 'toe room'. This means that starter plants that have begun to really grow up fast are given a pot that allows space for roots to fill, and larger mature plants also need a bit of extra soil to hold water between watering days.
* Any violet plant that is slowly growing or has a small root system is planted in a pot that 'pinches toes'. This means that tiny babies are transplanted in small pots. Slow growing varieties, weak or ill plants also need small pots. Small pots on these plants mean there is not extra soil to hold more moisture than the weak root systems can use.
When I do water, whatever that day is, I water ALL my violets. I have found that if I set aside a tray of babies or several pots to 'water tomorrow', I may forget them and they go without water until their wilting catches my attention. If I do remember them several days later, these trays or pots will be 'out of schedule' and will not need watering when the rest of the plants do, and next week I will have two watering days.)
I have found that if I do the first two things, the third is easy to do. If I use the same soil mix in all my plants, and use a correct size of pot for each type of plant, I can water everything all at once... and every plant is happy!
If a plant gets thirsty before the rest of the plants on a shelf, or in a tray... it needs potting up into a larger pot. If a plant is still moist when everything else is ready for water, it is probably in a pot that is too large.
Every time I try to 'compromise' on these three things, I have problems! If I follow them, and water at least once a week in the summer, my violets are happy!
1) I use the same soil mix in all my plants.
3) I water all my plants on the same day!
