Annual Begonia or Perennial Begonia?
Comments (23)That is weird Kyle. Rhizomatous (which rexes are of this type) are fairly easy. Are you overwatering them? Several of mine took a turn south due to the week I was at the convention in New Orleans. Most are still viable and some are putting out new leaves. These are the smallest pots and on top shelves. I've noticed over the years that plants I put on top shelves (begonias) often do worse than the ones on middle and lower shelves. I can only think that it must be warmer (heat rises) and causes issues. The other thing is not seeing as well since I could just be watering blind unless I take the tray down (I do that in one room - 9 trays in all that is a bit more work than I like). These photos are from March 12 as I have only taken a few photos of cuttings after that. I even got Escargot through winter this year! YAY! My 3 red rexes have never looked this good until I cut back on watering this winter. This big pot was started in September from 3 inch pots. 3 rexes, 1 U647, and Bashful Bandit in the middle. Sophie plants that I started over the previous winter and gave away several. Mary Bucholtz in the back, manicata in front plus several others.

Comments (7)Oh, my tuberous begonias stayed in the Pacific Northwest. Once the local university horticulture department put on display one they were really proud of (I guess) and it was really pathetic. One flower and a straggly plant. Figured if they couldn't do it I wouldn't try--most of their begonias were really gorgeous. I've known people who tried unsuccessfully. But I'm still surprised to say I don't recall ever having mildew on any of my numerous other begonias here. They rot sometimes. They get black spots kinda like the roses, which I attribute to not enough water, sometimes. But no powdery mildew. Now I suppose I'll get it!...See MoreCrispy rhizomatous begonia - advice please!
Comments (1)Try this one more time. I've typed out two messages so far and lost both - GRRR! Okay, that is a rex but still rhizomatous. Rexes can be a bit more challenging but only in winter since they may/will go semi-dormant. I don't think that is what is happening here though. A new plant will take time to adjust to its new living quarters so it may pout for a while but two months should be plenty of time to settle in. Did you repot recently? It looks like the plant is too deep in the soil - the rhizomes should be exposed. You can remove the older leaves and restart those. Check other posts for propagating by leaf. It can be a challenge for the first few times until you get the hang of it. Rexes (and rhizomatous) can take more light but can also do okay in dimmer situations too. More light - healthier plant but more water. Less light - leaves may get bigger but won't be vibrant - requires less water. Let the plant help you decide on where it is most happy. A terrarium is another way of insuring a easier plant to take care of but it has its own set of issues as well. Are you saying you have high humidity in your home too? Usually outdoors is a wonderful growing area for the warmer months if you want to go that route. Just make sure you do provide some shady area to begin with. Here is an example of a rex I started by leaf pushing the top off this seed starting tray....See MoreRex Begonia - How to make them happier?
Comments (7)I use Miracle Gro potting soil and all my begonias did very well this summer despite torrential rains in Sep and Oct (at least a couple of feet of rain). Just make sure the drainage holes don't get clogged. I had one pot out of hundreds that clogged (and this is while I was gone for a week during the monsoon or so it seemed like) and the begonias were looking pretty sad. I hope I saved them (pulled the rhizomes out and put them in a small container with perlite). Perlite/orchid bark is good to add if the soil seems heavy. I have a Canon compact and the flash is fairly easy to turn off. You may not want to if it is too dark in the room unless you turn the ISO to High. Some rexes from this summer shot by the little Canon....See MoreWoebegonia
