Propagating Cane Begonias


Betty Vander Poorten (10)
Doing it my way!

I take tip cutting about 12-13cm (5in.) in length. Always go to a node which has not flowered. This hopefully will give you a nicely shaped plant. If you cut at a node which has flowered, the plant will not branch.

My propagating mix for canes is potting mix 80%, perlite 20%. I have also used straight vermiculite with great success. I always use striking powder, a habit from nursery days in Victoria because I believe it to be beneficial. Lots of growers do not use this powder.

August for me is the best time to do cuttings, but I have had success in autumn before the cold weather sets in. On an east facing wall I have large terracotta pots filled with lovely canes which get sun till midday in summer – the more sun, the better the flowering.

In August I cut back to four nodes in the centre of the plant and three around the edge. This gives a lovely flowering plant by the end of November/December. Fertilise with Osmocote Plus. If things are working your way …. Don’t change!

 

Begonias, Cotyledons and Transplanting


The Green Thumb 2.0

The begonias that I planted in February are ready to transplant into individual pot. They’ve had some time to grow and they now have two true leaves. I say “true leaves” because the first “leaves” that you see when plants germinate are usually cotyledons or “seed leaves.” Cotyledons are structures in the seed that store food reserves. When many seeds germinate, the cotyledons emerge from the soil and become photosynthetic. They look like leaves but they’re not leaves; they’re seed structures. The true leaves of the plant are what grow after the cotyledons have emerged and have the characteristics of the mature  plant. For example, newly germinated radish and cabbage seedlings are impossible to tell apart because the plants are related, have similar seed morphology and the cotyledons are identical. Only when the true leaves develop can you distinguish between a radish and a cabbage.

The begonia I’m growing, is a bronze-leaved plant and the true leaves show the…

Begonia Bonsai Propagation at Logee’s


Logee's Plants for Home & Garden Blog

Begonia Richardsiana forms a bulbous trunk in a short time, is easy to grow and makes an attractive miniature-like tree. Its leaves are delicate and pointed with white flowers appearing from spring through fall.

Another plus for Richardsiana is its ability to thrive under dry conditions. I was in our propagation range the other day and caught up with Laurie, our Begonia grower. We propagate Begonia Richardsiana two ways at Logee’s. The first method is by cutting and the second method is by seed.

Here is how we do leaf cutting propagation. Although this way is quicker for the begonia to take root, it takes longer to form the nice bulbous trunk.

Sheering the present crop has two purposes. First, we harvest cuttings for the next crop. Second,  the crop underneath becomes a much healthier, fuller multi-branched specimen.

Choosing a cutting with more than one leaf nodes gives the cutting…

Rex Begonias: Parenchyma and Propagation


The Green Thumb 2.0

Rex begonias – the “king” of the begonias – are plants with their own unique look. These begonias aren’t grown for their blossoms; they’re grown for their foliage which comes in various shapes and colors. Rex begonias are great houseplants and they grow well in outside pots in semi-shaded areas.

What I find interesting about these begonias is the way that you can propagate them. Stem cuttings of these plants root easily but the most common way to multiply rex begonias is by using leaf cuttings.

To do this, you simply take a begonia leaf, turn it over and make a small cut across each of the main leaf veins. Then you place the leaf on potting medium right side up and use pebbles or floral pins to ensure that the back of the leaf is in contact with the medium. Within a month, small plants will begin to grow…

The illustrated guide to rooting begonia cuttings


Johntheplantman's stories, musings, and gardening.

 I’m going to need a lot of nice flowering plants. The Junior Service League garden tour is scheduled for April 28 and all of the urns and flower beds will have to look really good. I usually don’t even start the planting until the first of May because of the variable weather patterns in the North Georgia hills. Patsy’s going to love this.

I have access to a greenhouse, however. Due to health and other issues, I haven’t used the greenhouse for the last couple of years but when I found out about the garden tour last October, I decided to clean up the greenhouse and to save a lot of Dragon Wing begonias that would have ordinarily gone to the trash pile. As we changed out annual color last year, I saved a number of the begonias and potted them up to use this spring. Last week (march 7)…
