Perlite and Rooting Questions
1) How do you keep perlite from washing out the drainage holes in the bottom of rooting plastic or styrofoam cups? I made holes using a soldering iron tip and the holes are bigger than the perlite pieces. They wash right out the bottom. So I took some old window screen and cut circles that fit flat in the bottom of the cups, but, wow, labor-intensive. What is a better way to cut drainage holes? I'm thinking next time, maybe just make slices or very small holes using a box cutter?
2) Can perlite be reused?
3) What is the best way to transfer rooted cuttings from perlite to soil? I am new to rooting in perlite. In the past, I always used potting mix so if I was successful, the whole plug - mix and plant - were planted. I have never separated a rooted plant from the rooting mix. What is the best technique?
