I have 18 or so Begonias. Many are in original containers, (when purchased) and others have been in the same pots/soil for years.

One reason, seems my Begonias do best when root-bound, so I'm afraid to up the size.
Am I being silly? lol

It's been a very hot spring, high 90's, so soil dries daily.
I don't mind watering, but some Begonias are so root-bound there isn't room for roots to grow.

Pot sizes range from 2.5" to 8". The majority are in 4".

Should I repot 1 size larger or let be and continue daily watering?

Do Begonias require tall or short pots? Tall pots are getting hard to find. I've looked everywhere..
Plain, plastic pots, nothing ornate. Tall ceramics and clay are available, but I prefer plastic.

Also, what about soil? I have various Begonias, many w/o species ID's.
Is it safe to pot in a little lower pH soil, or not?

I know some here are Begonia experts. Please help.
Thanks much, Toni

I don't know what to do. Some roots are sticking out of drainage holes, 7" or more..lol.

Are your Begonias in straight Sphagnum? How often do you water? Wow! lol

A couple 'FAKE' Luxurians, lol, are still in 2" pots, stand about 1' tall.

Shallow pots are easy to find, 'depending on your definition of shallow.'
They're sold on Amazon, and sometimes Ebay. I bought plastic azalea pots from Amazon last year.

Can't believe a year has gone by since you stated Luxurian seeds. Sheesh, time flies.
Mine never germinated. Think it was too cold. Never got around to placing a heating mat, also, seeds were sitting a while. I give up on sowing altogether..lol

Now that I found the real deal Luxurians, no more searching or trying to sow..lol..

I thought Begonias needed semi-acidic soil? No?

The last month, I've been repotting plants by type. There's many left, but down to Begonias and Clivias..
Then, large plants like citrus, Bird of Paradise, Coffee tree, etc.

Anyway, hope you're doing well, Woe...take care, Toni

Finshed unpotting, repotting, 'many in fresh soil, but same pot,' ST'ing and fertilizing w/Fish Emulsion.

There's some Peat in MG soil...I ran out of peat, 'along with other mediums,' so couldn't add extra.

Woe, because MG contains Peat, when a plant needs acidic soil I usually add a handful, (peat) to a semi-large pot mixed w/other ingredients.
Soil is well-draining.

I'll have to snap new pics..think my Begonia pics are from 2011 and before. All but Luxurians, lol.

BTW, how's your seedling doing? Did you set it outdoors?
One thing I noticed, they're slowwwww growers. Since mine came in, nary a new leaf.
But, it's in the LR, w/little light. Very shady. It's too hot inside, 'no a/c or c/a' to place among other plants.
My other Begonias are getting more light, but they don't like the heat. And it's been HOT here..Today supposed to be 104F.
I need to buy a small, rotating fan to use in the room.

I wouldn't mind setting Begonias outside, but worried about ants..they've been a major problem.
Found one in my Begonia while repotting. I can't stand bugs!

Hope all is well. The Begonia Forum is slow. Why is that? Many love Begonias. Toni

Sounds like you're finished with the repotting already so this probably doesn't mean much but when I potted up those gift plants and the others I already had, I just used the same stuff I do for all of my pots. Glad I hadn't read this first, I would have been intimidated, I think. The plants are growing well though, so they must like their new homes.

I hadn't realized your plants were inside when you asked me about what kind of sun mine were getting. A lot of my plants (Begonias and otherwise) get ants when I put them outside but their performance outside makes me feel like it's worth dealing with those pots. Understandable when others don't feel the same way - that can really be a chore and ate up the better part of 2 days last time. Hanging plants still sometimes get ants, but it's much less likely. Do you have any places to hang (some of) them?

Is it just your "plant room" that doesn't have A/C or the whole house? I thought Begonias did like heat. Is that just certain kinds? I know the ones my neighbor gave me have never been inside her house, she's had them for decades.

Agree about wanting to see pics!!

I'm happy seeing you here.

More gifts? You do have a kind neighbor. Very generous. Did she give you more plants since, was it yesterday???

Yep, ALL finished repotting Begonias, a couple were in the same pots, um, 10-yrs......Now I'll move on to the next type of plants..etc.

Purple, the entire house is w/o a/c..So it's hot..Yesterday got up to 103F..Oh well, they said 104.
I didn't do a darn thing. Didn't want to move...Fed the birds and Coco..I ate dinner at 11pm..

Begonias like warmth, but not harsh heat..hot hot heat..the sun shines directly in the plant room. Temps are the same as outdoors, maybe higher since the sun has been so strong. It's too much for fragile Begonias.
When I stop at the store I'm planning on buying a small, rotating fan for that room.
BTW, at night, 'gonias like it on the cool, not cold. They winter in the same room, 'which can be icy, during winter months.

Purple, usually in summer I set Begonias on the side of the house on the third tier of a shelf..the upper tiers hold Hoyas. It's very shady..
But, like I said, 1. it's been super hot/sunny and 2. ANTS, LOL. I don't care if bugs stroll through my plants when outside, but when they come in it's a different story.

Purple, my Trandscantia is still outside in a pot of water, soaking 2-weeks now..there had to be 50000000 ants, on this plant, in my house!!! I panicked when I saw them. They were EVERYWHERE. When I hauled the T out out the house, ants were swarming over my hand..YUCK!!
I found one ant in Begonias while repotting..there were probably more, but it took a couple days to finish repotting. Begonias were on the floor, in order, waiting their turn. I believe ants communicate..'get out, she's gonna get you.' lol.

So, this year Begonias are in the house. But, who knows, maybe I'll change my mind and set them out. When it cools.
When I asked about light.....
Your BEAUTIFUL, basket Begonia is hanging on your front porch. I wondered if the sun shone bright, strong or shady. See what I meant? My front porch gets direct west sun.

Do you bring Begonias indoors during winter or is it warm enough they'll survive? Does your neighbor keep Begonias potted or in-ground?

Purple, no place to hang plants, but I have a few poles meant for hanging plants, bird feeders, etc.
But, they're used up and get too much light for Begonias..mostly west light. I placed a Wax Begonia, 'saved from the previous year,' on one of these poles, and it turned super red..burned..Think I have a pics.

2010

2011, in shade

It actually looked nice all red, but I felt bad for the plant thinking it might hurt. Was it sunburn??

Anyway, happy you're here, but it's kinda slow.

How are your new Begonias doing?

Oh, it's so dark..looks like the storm in The Wizard of Oz. Thunder and lighting, temps in the 80's, high humdidity..if I'd known, my Begonias would have been outside..sigh..

Besides being "cane" (and the one rhizomatous) I don't know what kind the Begonias are from my neighbor. Sorry if I was confusing, I was referring to the same ones from a few weeks ago. She keeps them outside all summer, then in a shed with a couple windows for the winter. She said she turns on a space heater if it's going to be below 25. I don't have that luxury, will have to bring them in. The main room I keep plants for winter stays about 55-65 with a south window.

They're in quite a bit of sun here at my house, from sunrise until about 11:30, then again after about 3 or 4. I put updated pics of them on house plant forum yesterday. They don't look sunburned to me. The new hanging basket one, either. In just the week I've had it, it's started to make flowers, I suspect from more light. At the store it was under that black mesh shade cloth. I was afraid it would be less hanging where it is but now I don't think so. That stuff makes more shade than it seems like, I think.

Your hanging plant pictured above has a lot more flowers in the sunnier spot.

When you have time, please post pics of your Begonias. A couple people like HCM? and Woebegonia are very helpful.
Problem is this thread is slow.

Your neighbor is really dedicated..dh would kill me if I kept a heater on in the garage, lol.
She has a super-green thumb. For one, heaters dry air..Begonias love humidity, so she must have a secret I'd like to know..lol.

She gave you lovely cuttings...very healty and so big.

Purple, your house temp and south windows are perfect. The only addition would be humidity..but it may be humid there?
If not, there's always humidity treys, and misting..and/or a humidfier.

We might not have a/c but no matter what we can or cannot afford, I use a humidifer in winter..Not only for plants, but I can't breath in dry air..humidity can drop to 5%.

You're right Purple..Wax Begonia has a lot more flowers..lol..But, is it sunburned?

Anyway, I'm glad you like Begonias, too. lol. What I've seen, yours are doing great..

Did you ever repot your Begonias?

Didn't realize it's been so long since I've been here.

Well, the heat eventually got to me. 104F w/heat index of 109F got to be too much.

After a rather lengthy 'TALK' w/dh, he gave in and bought an a/c 7/5/12...Miracles do happen..lol.
I keep in running when days are 99F or higher; since the 5th it's been on approximately 5 times.

My poor Begonias took a toll for the worse during our short but horrid heatwave.
The canes did okay, but others look awful. Especially my 6-yr-old Venition 'sp' Red. I feel terrible. It was one of my favorites. I doubt it will survive, If no growth forms by late August, or when plants are brought back in for winter, it has to go. It's out of my hands, did everything possible for its survival.

Ants. What's with ants?
The 18th of July, they were running throughout three rooms of the house. I was horrified!!!
I had a doc appt, so killed as many as possible, but had to leave. When I returned home, 'felt like signing myself in the hospital, HATE ants,' ants were everywhere.

I spray ants w/vinegar which kills on contact...I usually spray enough so there are small puddles where they congregate, so unless an ant/s happen to run in the puddles, they're safe.

After two-days of a trillion and one ants, 'believe me, I have used non-chemical insecticides, home-made remedies w/o success,' I set out ant baits called Terro.

Ironically, it was as if they sensed I placed baits out..The following morning, they were gone. I KNOW this stuff works, but not that fast!

There's still a few ants in the kitchen, 'YUCK' but I use the vinegar when they happen by.

Woe, how does your recipie kill or deter ants??? If anything, it sounds like they'd enjoy dining out..lol.

Eahamel. I've tried Borax outdoors, but it doesn't help. I can't use inside because we have birds and a dog. My birds are not caged during the day. They sometimes fly from room one to room two, but are curious and possibly nibble poison.
The baits are in areas birds/dog cannot possible get.

Woe, just reread the first line of your post..ROFL. Too funny. Taking a fan outside. When temps are 100 and humidity 75% and higher, central air won't cool off the outdoors, lol.

Purple...sorry, just noticed you asked if I repotted Begonias.
Actually, they were repotted in spring.
But, I experienced.
I tried a grittier mix as some say it's does well on their plants. My Begonias are unhappy. Those potted in this mix will be repotted in the same soil recipie they have been in throughout the years.

Old but new to me. My motto: Don't fix something that isn't broken. Toni

Yes, that killer heat and harsh sun really distroyed some nice specimens. If I had thought about it, I should have moved Begonias in the LR where a ceiling fan was running. Not much light, but it might have helped.

No new pics, since they look terrible. lol. I took a pic of my Wax Begonia this morning. It's outside, and was during the heat wave, but IMO Wax Begonias can withstand most weather. Including scorching sun.
However, it lost a few stems, too.

Also, while misting the other Begonias, I broke off a tall piece.
I'd like to root, but don't know how it's done. Water, soil?

I could take pics of the other 'gonias, but to shame. lol.

Purple, it's still in water..lol. I KNOW if it goes in soil I'll forget to water. It's a cane type.

If/Once it roots, I'll place in soil.
Thanks...Toni

Great..the last time you posted you were a bit worried about your luxurians. It all worked out..

Yes, when you have time, please post. What conditions is it getting?

Yes, I see the split. I believe luxurians is a slow-grower.
When I was hunting one down, I also reseached..came across more sites that TALKED luxurians than sold them..it was said B. luxurians are slow-growing.

Is Stewart's Luxurians, the one you sowed? The same place er both ordered from?
I thought his seeds were B. Luxurins w/very thin leaves? Not Stewart.

What is your Begonia potted in? I see very little growing medium?? Whatever, it's doing well. Very healthy.

I'll have to Google B.Lee pics..don't know what they look like. Stewarts have thicker leaves than a true, thin leaf B. Lux.

If you recall, the seller had a pic of a thin-leaf Lux?? Guess that's what Mark meant, 'different thread' by sellers being deceptive.
