How to layer a raised bed
I built my raised bed about 18" tall and i was wondering how to layer it. I once heard i should use a weed mat as the bottom layer so i can keep weeds out and still have good drainage. Others just say to mulch in your new soil, compost, etc. I don't know what i will be planting there. Possibly vegetables and flowering perennials. My soil is very hard and compact. Should I not even try to mix in new soil or should I give the plants as much growing depth as they want? Will they grow through the weed mat? So many questions, just very overwhelmed. What do I do?
