African Violets in Gritty Mix or 5:1:1
Comments (49)Hi Al/plantcrazed/et. al., I thought I should come back and share some results from my "experiment" that I started at the end of April. The controls in my little trial were almost non-existent, but I think that actually makes the results more relevant to me and my growing conditions (and hopefully others will get something from this too). Back in April I got an order of leaves of 19 varieties of AVs. 14 came as pairs of leaves, so I decided to try growing them in different media. As I described in my post in mid-May, 14 leaves went in 100% vermiculite and 19 leaves in 100% turface fines (the smaller stuff left over after sifting for other mixes). The planting tray is an old kit I had leftover from years ago that has a clear cover for germinating/propagating. I had grand plans to carefully measure watering, leaf condition, first sign of roots/new leaves, etc. (like a good experimenter would), but the same day I planted the leaves my toddler ended up in the ER, kicking off several weeks of stress and doctor's visits, not to mention usual life events and adventures when working full time and caring for a small child. My plant care regimen settled in to, basically, watering when I noticed they looked dry. After the plantlets started to appear I took the covers off the trays, but otherwise I've just watered and left them under fluorescent lights and hoped for the best. Here are my results. Vermiculite 4 have plantlets, all of which seem to be growing alright 5 are mostly-dead or all-dead 1 formed a nice-looking plantlet that subsequently died, tho the leaf is still there and has roots 4 have roots but no sign of new leaves (yet?) Turface fines all 19 leaves are still alive 16 have multi-leaf plantlets 1 has a new leaf just beginning to appear 2 are strongly rooted and some gentle investigation revealed new leaves that just haven't broken the surface yet (I had just finished watering when I took this photo, which is why the turface shows wet and dry spots. This is what my usual watering of this tray looks like) A few other observations: the leaves of the new plants in the vermiculite are larger than any in the turface the leaves of the new plants in the turface are much smaller, but there are many of them, they are a strong green colour, and have a vital appearance (my experience tells me these are stronger plants than in the vermiculite) one variety was not in very good shape when it arrived. I considered complaining to the store owner about the quality, but see above re: bigger life priorities right now. That variety didn't survive more than a few days in the vermiculite. The leaf just rotted away. In the turface, it slowly rotted up the stem towards the leaf, but then rooted from the remaining piece of leaf and now has a lovely little plant growing: What these results say to me is that, for my horrible, neglectful treatment of these leaves, the turface was a better growing medium. I'm sure Al or Kevin/ewwmayo would have the correct terms for the properties of the two media, but I would say it seemed like the vermiculite contributed to a less stable environment - it went from a soggy mess when I watered to very dry, very quickly - and the turface was much more stable and allowed these poor things to survive despite my neglect. I've read some of the very lengthy threads about the properties of the various gritty mix ingredients and it makes sense to me that a plant like an AV that doesn't like to dry out but also hates being soggy would appreciate the turface's qualities of holding water but allowing for drainage and air movement through the medium. I think from now on the turface fines will be my preferred method for starting AV leaves (and likely other similar plants like episcias or begonias). I also moved two other AVs (a standard and a mini) into a modified gritty mix (1:1:1, but perlite in place of bark). So far nothing meaningful to report, though neither plant has bloomed and the mini seems to be happier than the standard. But with my neglect of the plants lately I don't think these results are meaningful, beyond saying that AVs can actually survive in the gritty mix even with an inconsistent and sub-optimal care routine. If there's anything interesting to report as these AVs continue to grow and I pot them up (likely into a gritty mix of some sort), I'll be sure to come back with an update. I would happily accept comments/questions/criticisms of my results, but please be kind in your criticisms of my care routine. I might be bad with my plants, but this little one is thriving: Thanks everyone, Melanie...See Moretrue colors for african violets
Comments (2)Thank you Fred. I do hope that the information you passed along to me will be exactly what happens with my violets. It sure is good to know that I am doing everything right. I've only been "violeting" for about a year, so any good tips help a lot. Thanks again. Miss Linda...See MoreMini African Violet leaves fold up
Comments (5)Thanks Joanne, I had read somewhere that lighter leaves needs more sunlight, I was given a large AV once that had turned white from the wrong lighting, the woman knew I could take care of it. For the record that was a mess. At first I thought it was diseased so I kept it away from my others and removed all the white leaves and by the time I got to the newest green leaves I had an small AV "tree" with the long leafless stem LOL . Then I figured out it was just a lack of sunlight. I ended up with a tiny top and just rooted it and placed it in the East window with my others.. It was probably the best thing for it. The lighter green of mine made me question it and I just wasn't sure if it was a lighting issue. I can see what you're saying. I've rinsed it and placed it in my northern window (bright, indirect light). Funny how the growing conditions can vary from hybrids. My other 4 minis are all slightly darker in tone and has the heavier fuzz on them. They are already uncurling. Looks like you solved it! Thanks Joanne!...See MoreHow do I determine the "official" name of the african violets I have?
Comments (35)Jeff,,,,they choose to have a sales department that doesn't give a tinker's darn about what will make their CUSTOMERS happy. Have you seen their operation????? Take a look and get back with me. This is no longer a mom & pop company operating a few greenhouses in their back yard. Terri I will respectfully disagree. You cannot go to their website and "check" for any degree of certainty. Look at the other recent threads, and you will find us, the african violet serious customers, advising newbies that even if the pot has an Optimara label, you should always label it a "NOID-might be Opt. this". As has been stated, some people don't even want to trade for or put Opt. leaves in Round Robins. Why is that???? Because with no id to begin with they don't want to take a chance of passing along a misidentified plant leaf! And look at some of their color pix. Can you reeeeaaaallllyyyy tell the difference between a few of them???? I don't think so. I know I have my doubts about some of the colors and MY perception of what they are. Do I buy Optimara's? Yes I have, because they have a few I am in love with. Fortunately the ones I love CAN be ID'd because they are that one of a kind. Opt. MyDelight, Opt. Trinidad ll, Opt. MySensation and a few more. But the mainstream Opt's???? Good luck. Ok, I go into Lowe's. I look at all the plants (I am not just a violet person! haha). Other house plants are labeled. Outdoor plants are labeled. Rose tags say Rose Oklahoma, Rose President Lincoln, etc. Liriope is labeled as such. Hosta has a name to it beyond "Hosta"!!!! Do you think the average gardener cares what named Marigold, Hosta, Salvia, Helloborus they are purchasing??? NO! More of them don't care than do care. And these are things that will come up every year as long as they are taken care of! But the point is,,,they have real name tags that tell you all about the name!!!!! Honestly they just want to get it planted for color, landscaping etc. They are not passing them on by cuttings to the extent we are doing in basements, windowsills and any other spot we can find. But guess what.... Optimara says African Violet. That's it. Something that they know people set up lights for, propagate, learn about with various techniques,,,,,they know we cherish and keep and trade them with our friends,,,,. And they can't give us a TAG!!!!! A lousy name TAG that can be mass produced cheaper than we can buy 100 for online!!!!! ($1.78 free ship just in case you want to know!) Who do they think they are? They are snubbing the very people that make them who and what the heck they are!!!!! They labeled them back in the day!!! I still have some of the old tags! They got too big for their britches and thumbed their nose at the very people that got them there. I don't want to hear their excuses for no label. Worker's can't read and mix them up. BULL SQUIRT!!!! Then hire better workers!!!!! NO EXCUSES!!!! Ok off my soapbox now, not yelling at you Terri, or anyone else. I have said this very same stuff before about Optimara when this subject has come up. This is not a personal attack toward anyone except Holtkamp/Optimara. And any other company who does this. Shame on them. I am stopping now and I will post no more in this thread with my opinion about this subject. Whew. I am done. Rosie...See MoreRosie1949
