Early in the spring I bought several trays of plugs of begonias (normal and trailing) and geraniums.
After filling all my baskets and troughs I had quite a lot left over which have spent the summer in small (3") pots where they havent grown very much mainly due to lack of attention. They have suffered from either too much water or too little, most are about 3" tall now and look OK.
Will I be able to overwinter these in the greenhouse, should I pot them on and will these types of begonias develop tubers that I can use year on year.
