Let it dry out some between watering. Is it in a very humid environment? The leaves look moist in those photos.

A clay pot would probably be better than plastic/Styrofoam in this case until it gets to a height a few inches above the soil level.

Thank you. So I should wait to water til the top of soul is visibly? 40 % humidity. Probably just spritzed it with water.

The rule of thumb (or finger) is to insert your finger into the soil to one inch. If it is dry to the feel then water thoroughly. Once you have several hundred plants, you almost know when it needs water and you would get pretty dirty inserting your finger into that many pots.

I would not spritz begonia leaves indoors (unless you are propagating under plastic). I think you have ample humidity for canes. For some very tropical
begonias you would want to set up a terrarium. Canes for the most part
can take normal house air quite well.

I often over-water
which is okay as long as it dries out some in a day or two. You don't
want it to stay wet for days on end. Some plants, I have to go very
easy on water because it is in a bigger pot than it should be, the pot
is plastic, and/or the plant resents wet feet. On these I drizzle water
on the surface when it feels dry to the touch or the plant shows a
little wilt. Other plants are water hogs - the pot is too small, the
pot is clay, the soil may be worn out and drains too fast, and the plant
just seems to love water. On these I water thoroughly to see water
gushing out of the bottom.

So if your soil stays too wet then
the strategy is to do one or more of the following 1) water less 2)
change the soil 3) change the pot type 4) change the pot size. I know
this is an oversimplification of the issues of watering but it hits most
of the major points. Do it conversely for pots that stay too dry...

Here is Brad's Begonia World which has1 great tips on how to care for your begonia.

One of my Miniperba canes.

My own seed grown cane
Down Home (with orange bloom) and aconitifolia (cut foliage - newly started)
I think this is U177 after two months of growing from cutting it to the ground.
White Ice is a new one for me and is in a six oz drinking cup surrounded by rhizomatous begonias

Albo-picta above has really narrow leaves.

Looks like I cannot insert text between two photos once I include another photo after the fact.

Most of my canes do not get a lot of light in winter since they are 1) too tall and 2) not enough lights to accommodate them all.

Grey Feather (stripe down the middle) and Lana (one cane added to the pot) in bloom. The red bloom is a common cane (probably some form of coccinea)
Either Orange Sherbet or Orange Rubra. This one has given me fits for several years but this winter I've really cut back on watering - just drizzle the surface and it has made a big difference.
Jim Wyrtzen (hope I spelled that last name correctly) - anyhow a sampling of some of my canes

Wow! Begonia life goals. Ha. Those are all so beautiful. Thanks for sharing.

I have killed many a begonia over the years but after a while you kind of learn to do what needs to be done to have some success. If it was easy then we'd never learn anything and probably get bored.

A few other begonias (not canes) mid October before bringing indoors for winter

Judy Cook

Blue Wings

Fire Storm

Janet Brown

Jealous Zebra (striped leaves) and Kula (bronze and green color)

Soli-mutata (center) with Valida on right side

several different rexes (Salsa, Pink Diamonds, Hugh McLaughlin, Merry Xmas Curl, Lady Helene Jaros)

Purple Snow (jagged edge) with colorful coleus, phutoensis (rounded leaves), and other begonias poking in on the edges.

Several begonias - rexes, luxurians, a cane (probably Little Miss Mummey), PHOE's Cleo, Virginia Jens, and letestui)

Sinbad in an 18 inch pot with Selph's Mahogany in a 10 inch glazed pot below. These got full sun until 2 PM through the entire summer. Volunteer impatiens in between the flagstone did very well as long as I kept it watered.

Good Job!!

Hc mcdole,. I see from the photos you shared you have some eye lash type begonias. Are they not pretty similar to growing the cane types? I have been eyeing the tiger kitten.

Hi Danielle,

Eye lash type begonias are rhizomatous begonias so the only thing they share with cane begonias is the family name. The care is probably similar though - good light, warmth, and watering as needed. I would definitely try some rhizomatous begonias but be careful with the eye lash (bowerae) type since too much water is like a death warrant. You might try some bigger rhizomatous to begin with that are easier to grow and manage and then graduate to the bowerae hybrids. If you do try Tiger Kitten, I'd probably go with a terrarium to begin with.

The one you probably noticed above that looks similar to Tiger Kitten is Persian Brocade and seems to be much easier to grow (at least for me).

Still alive! It has been through so much. If there was a fire and I could only take one plant it would be this one.

Looking Great! You must've found out what it takes to make it looks so good.

We just moved to a new town and our new place has so much light. The begonia is doing really well. One of the canes got a little flattened during the move.

Way To GO!
