Being very new to the garden 2nd year i bought a dozen large trailing begonia corms 3" approx a couple of months ago . I want to plant 3 hanging baskets with them 4 in each 14" basket
I have a greenhouse with a paraffin heater .
I'm not sure when or where to start them off ? in trays or straight in the baskets ?also how deep to plant them . I have a mini greenhouse set up in the spare room with heating on as i am trying a few dfferent seeds ( fingers crossed) so i could put them in there .
Would be VERY thankful for any tips and advice , oh i live in the scottish borders .
