I patted down the soil a bit.
Had my work inspected.... This is very important!
Some plants that produce tubers or rhizomes like a moist soil for growth, but you have to pay attention to their needs and see that they don't stay too wet, otherwise tubers rot.
What would a set up like this likely do? This might keep the plant extremely well drained but allow the roots to take up all the moisture they require from a soil mix that might otherwise be considered "heavy" for what you're planting.
So??? Will this work??? Have you tried it on other things??? I'd love to start a discussion...... Comments?????
