Eugen: I also always wear long trousers. Do they carry diseases where you live, here they carry the Lyme disease and meningoencephalitis.
bogatin: I also use bogatin. The holes were sitting for 2 weeks and I think they were ready.I've already planted them. I don't think that the rain that is coming will do any harm also I don't think that the temps will drop too low.
I think that plants can do well in native soli, but it won't ever reach te quality of good potting soil or coco. On the hillside spot and on the backup spot I have some native soil beds so we'll see side by side in which soli they will perform better. The biggest plus at native soil is that you have unlimited suply and of course you don't need to carry it anywhere. Well as said we'll see.
I'll also mulch my holes, but I normally do it about 2 weeks after transplant, when the planst are bigger.
