how to start begonia. is it seeds. how to use last years flower, for this year
There are a number of different types of begonias; some are started from seed (usually the pros only do this), cuttings (if you have mature plants you love) and tubers. Tuberous begonias are the ones you often see in big, showy hanging baskets and mixed containers. The flowers are large and colorful. See examples here:https://www.leafari.com/begonias.html

I have an outdoor hanging basket of begonias. The blooms have died off. Is that it for the season or can I get it to bloom again? Would bringing it indoors help
Removing the spent flowers or deadheading will encourage the plant to rebloom. If you are fertilizing you begonias use a product lower in nitrogen and higher in phosphorus and potash to encourage new flower development. I have had great success with water soluble fertilizers like super bloom.
I have grown bergonias from corms planted out now in various baskets and boxes they now look very strong with lots of leaves but not a flower in sight they are illumination orange I am new to gardening and bought the corms from mirror website don't know if I bought from correct place or whether that's relevant they seemed to struggle when first in greenhouse took a long time to grow may be cold weather earlier in year but as great as they look now no flowers can any one help or may be I need more patience.

Make sure you are not over fertilizing. Too much nitrogen will inhibit flowering.

can I repot a strawberry begonia in July or does it have to be in the spring?
I would wait until the plant is done flowering or until the weather is a bit cooler.
Only go up one pot size to avoid root rot.
