    I'm new to these plants, I used to hate them, this year I've fell in love.
    My question is...... is it worth overwintering? My plants where bought as plugs, £1:50 at most
    How does that compare with overwintering? I'm guessing my begonias will bulk up?
    What do you do?
    Is it worth overwintering? If so, how do I do it?

      Loki. Yes one of the little problems. Might I be correct in thinking you refer to Begonia semperviens, often used as edging plants, pink, red and white some with bronzed foliage? Usually these are discarded at the end of the season but they are easy to take cuttings from and even to pot up and keep the old plant through the winter. Keep them on the dry side, as even under glass over moist plants can suffer due to frost-like temperatures and conditions. In an unheated GH, a sheet of newspaper will often suffice overnight.

      Begonias are quite a large family. Even from plugs, various plants will produce a corm. These corms can be lifted, dried and stored over winter, or potted up and allowed to rest, just keepin the compost damp. Always remember, Begonia corms have a concave top. Aviod this from filling with water, the corm will soon rot.

      Begonia Rex is one of the big boys. Fantastic foliage and allowing for various methods of propagation. Cutting the veins of the leaves being a great favourite. Back to the sempervirens. My GH staging is covered with compost. This comes in handy at times as, such as B.sempervirens, allow the seeds to fall and bingo, you have plenty of new seedlings. Good Luck and enjoy your gardening.
