11232 zone 7?Q.Dormant Or Not?
I've read the response to one of my earlier questions regarding a Begonia cutting. Unfortunately it did not cover my particular problem. My cutting is from the winter Reiger Begonia's. After propagating if from one of its leaves, it grew to about 2 to 3 inches high, which forced me to repot in regular small pot. I give it exposure to grow lights for now over a month and although it still looks like when I repotted it. If it's a winter variety as its often described,why doesn't it show any growth? I hesitate to fertilize based that if it's in a semi dormant stage? But how can it be in a dormant stage if its known to be winter growing type?

Certified ExpertA.Unless you are giving it a dormant stage, on purpose, it will not go into dormancy indoors while under lighting.
If you are certain that the cutting is well rooted, and was established when you transplanted it, then it will be time for fertilization.
The term "Winter Begonia" will describe the flowering habit. They will set flower, usually once done with their vigorous growth for the year. This is at the end of their yearly cycle. They should not be actively growing at this time, in nature. Since it is indoors, you will have to force dormancy each year.
Your Begonia is a hybrid that will be treated more like the Tuberous Begonia side of the lineage.
Here are a couple of articles for caring for these:

March 28, 2020Q.Plant loss (begonias) from Pythium?
I am only a home gardener and I grow a large number of begonias and over the past couple of months I have lost over 50 plants. They include mainly cane-like and rhizomatous types and they grow in different areas i.e. shade house and patio. I think it is a fungus/pathogen root rot type of problem and I have no way to stop it from spreading from plant to plant, my plants start off looking sad, droopy leaves, soft/rotting rhizomes and also may have mealy bug which I can treat. I do not over water my plants and practice good plant hygiene. I belong to a society but their help has been limited. I have read your section of Treating Root Rot but the problem persists. I have used different fungicides Anti Rot and Eco Fungicide. Once a plant is re-potted it seem to be even more susceptible to rot. I am very upset and looking for any advice that may help. Mainly I want to know how to stop it spreading. Removing affected plants does not stop the rot appearing in other plants.

Certified ExpertA.Most begonias will grow around a foot tall and, if healthy, may spread out the same in width.

NE28 9EEQ.My Trailing Begonias Have No Flower Buds
I have 50 begonias which I stored over winter, they have lots of leaves but no flower buds. Can I have enriched the potting compost could this have caused this problem. can I reverse this.

Certified ExpertA.If you have added too much nitrogen, then you can offset with potassium and phosphorus. If you have added enough nitrogen to start showing burned tips, then you will have to start with fresh soil.
This is almost always caused by too much nitrogen, and not enough phosphorus and potassium, with more emphasis on phosphorus.
Before fertilizing, make sure that your soil test confirms that you need to feed. Once it has confirmed what the soil lacks, if anything, then you can add just those nutrients.
Here is an article that will help you to care for the plant:

June 3, 2020Q.Problems with a no. of begonias in large pots kept on a porch all summer
even though they are deadheaded at least once a week, and kept watered, they are starting to show some sgns of dieback, or drooping leaves.

Certified ExpertA.Perhaps they're getting too much water or aren't draining well enough. Begonias have thick stems and don't need a lot of water. The drooping may be due to stem rot from improper drainage. Check the situation with the soil in the pots and lightly feed them if you haven't already. A slow release balanced fertilizer will feed them all summer.
