Why is it bad to till wet soil?

I think you're conflating two things - tilling wet soil and jumping straight to 'artificial' soil to create particular conditions for seeds to grow in,but the one doesn't necessarily lead to the other....

Pinus pinea close to the house

I don't know that I'd consider it dangerous to plant the tree that close, but from a design perspective I wouldn't do it with any large tree - the tree will eventually dwarf the house and the effect ...

When rooting cuttings in water, should the water be exchanged regularly?

The water may work better over time, until bad things grow. The cuttings produce auxins, the plant hormone that causes roots to grow. This does leak out of the cuttings; an old technique for striking ...

Think this rooted?

Looks like your plant has gone through a rough path. It has not one but multiple issues. It is definitely under stress. The leaves are dried and curling which shows that lack of humidity. If there ...

Will shaving the top of a Red Maple's roots hurt the tree?

Yes, of course it will hurt the tree - it will be cutting away part of the system that transports water and nutrients to the tree. Often in cases like this it's best to decide that you want the tree, ...

What are these soft white things in my soil that are ruining my plant's roots?

These 'white bits' are vermiculite or perlite. They are added to potting soil to keep the soil from compaction. They have absolutely nothing to do with plants getting root rot if that is indeed what ...
