In May I decided to grow some petunia plug plants in my greenhouse. I planted them in cell trays and they grew really well and big. The problems started when I transplanted them to baskets, the compost just crumbled away from the plants, the roots weren't bound around the plants to hold the compost together. The plants were big so I couldn't leave them in trays any longer and I'm sure I watered them correctly. I've tried to grow plugs before and the same thing happened so what am I doing wrong? Is it the type of compost I use which is BQ?
