Thank you all for your help. I have peat based substrate, vermiculite and perlite, so I should be able to make a suitable mix when the time comes to pot up the baby plants.

I didn't know they were heat intolerant, so it will be interesting to see what happens if we get another heatwave, where temps in our appartment can reach 30-32°C. I know that my grandmother's plants often experienced a few weeks of such temperatures in the summer, but they didn't seem to suffer too much.

I'm no expert, but I've been growing African Violets alongside my Phals for about five years. They seem to like the same growing conditions, and they're almost constantly in bloom, so it's nice to have flowers at times when the Phals are between blooming. Mine are all on a kitchen/dining table, in a south window, with sheer curtains drawn when the sun is shining in. Temps in my home range from 68F to 74F, depending on time of year.

I happen to be a top-waterer. Similar to my Phals, I will water (room temp tap water) when they are approaching dryness. For the AVs, that is when I can put my little finger in the soil a quarter to half inch and not feel any dampness. I do dab off any water that gets on the leaves, but every time I do that, I can't help thinking to myself, how do these plants survive in nature, getting rained on? :scratchhead:

I've been using either an African Violet mix or an all-purpose mix, but I cut either one heavily with perlite to make the soil more airy. I often see it recommended to repot AVs every six to twelve months. I don't generaly do it that often unless it's a young plant that is growing rapidly. Have patience with your cuttings. It does take a long time. Yours look great in the pics!

+1 on the Violet Barn. I learned a lot from their site when I first got my AVs, and I still think they're a great resource for AV information.

I thought I'd give an update on my AV leaf cuttings. Thanks to your help and the Violet Barn site the new plants are doing really good. I potted several plants separately, and the rest are together in a bulb pan. I know that's not how they're grown, but that's how my grandma grew hers and I wanted to do the same for nostalgia's sake. There are a few too many in there for long term growth, so I'll try to gently remove the smallest ones and pot them up separately.

It may sounds silly, but I feel closer to my grandma and have more vivid memories of her just by looking at and touching 'her' African Violets. More so than with photos. Probably because the plants are real and trigger memories via several senses and not just sight.

Plants with sentimental lineage are so special. They look great! I also love them in a grouping.

Those look really good!

I think it is wonderful that you have some of your gram's African Violets. :)

What a beautiful way to pay tribute to your grandma and keep her close. Nice work Camille :)
