Begonia started from seed BUT no tuber grown???
Comments (4)I uses to live in San Francisco and had no problems with begonias growing under a porch. They always bloomed profusely and tubers always got bigger each year. Even the seeds i started in march of 2011 made tubers the size of a baseball. Albeit, we have a long growing season and the right temps. I gave them all up and moved to MA and boy is gardening different. I started with Blackmore and Langdon seeds feb of 2013 indoors in Boston. Those that survived the move outside all created tubers the size of a peanut to the size of a golf all. Out of about 100 seedlings, I culled out about half that did not have double blooms and the next spring, only about 20 made it. I kept them too cool in the basement. None bloomed summer of 2014. Mainly because I used regular topsoil with some weird mulch incorporated. They did all survive and their tubers were slightly bigger. I have started more Blackmore and Langdon seeds.mi started a batch dec 15 2014 and about 100 have been reported into 50 cell trays. I just started another batch last week just for backup. They grew really well when I had them under a 4foot shoplight on a shelf above the stove but started dying and damping off when i moved them to the basement with no bottom heat. My advice is to start very early if you want tubers and enough time to evaluate flowers to cull, being feb a the latestThey generally create tubers in the fall when day length decreases so they need enough leaves and a big enough root system to do that by September. Also give them bottom heat and use a looserepackaged potting mix. I made the mistake of potting them up in whatever was around only to find the the pH of the black mulch I used was close to 7.5...See MoreIs Blackmore & Langdon begonia tuber worth it ?
Comments (4)I ordered about 12 bulbs from them directly in 2010. They arrived in little paper bags in march and seemed really small compared to domestic tuners about the size of a walnut. They were all clean and had pink growth. I didn't think they would grow to be exhibition size that year but they did. They filled out 2 gallons pots well, most only had one or 2 main stems but flowers were still gigantic for small plants. When I dug them up that fall, all the tuners were the size of my fist. The plants were even better the following year. I started them all in Feb and they were blooming by end of May with a glorious show until September when I had to abandon them. I love their begonias but don't have the money to buy named tuners anymore so I've started from seed. The blooms were as advertised....See MoreBlackmore & Langdon Begonia bulbs The Worst
Comments (8)If I had the money, I would buy again from them directly in a heartbeat. It's just unfortunate that they only ship tubers to the united states once or twice a year. I grew them and they were wonderful. They were slow to grow though, as I've heard cutting grown tuberous begonias tend to be. They are expensive for that very reason. They are named cultivars. My experience with them is that they are different than say amerijybrids which I also grew. They are grown for flower size. It takes a season for them to really beef up. The amerihybrids were bushier and more floriferous but they don't compare to flower size of petal count of blackmores cutting grown tubers....See Moresources for tuberous and rex begonia seeds
Comments (1)For tuberous, try Blackmore and Langdon in the U.K. (see my recent post), or Antonelli Brothers in California....See Moremaryjozone5
