Hanging bags

I did these last year and found only the busy's did well in them,how do you plant yours up.do you use water gel and what food do you use............yours looked great last year.

Busy lizzy do well in the bags but Mariolds do even better or the small Begonias , I do use water gel and I also add a small amount of plant food granules that I buy from Poundland , the food granules last for 6 months
I also add water to the swell gel BEFORE I add it to the bags , then you know how much its gonni swell up and not pop the plants out the bag , lol .

thanks for your advice,i will give them a try.............
