Digging a square planting hole may prevent roots growing in circles and developing 'root girdle'. Slashing and cutting roots also helps prevent this. No Martha Stewart dainty teasing!
For perennials, unless you're using old stems to mark the plant's position in the garden, cut stems right down low near the crown as that's where the new growth forms.
Beneficial insects will look for large colonies of aphids to lay eggs; if you see a few aphids and they're not damaging anything, leave them.
Landscape fabric isn't great for weed control as the weeds will grow above or below, however, it is good for erosion control.
If transplanting a large bush or small tree, without machinery, the plant can be raised to ground level by filling the hole as you go. Roll the plant to one side and fill the hole a bit then roll to the other side, on to the soil that's just gone in, and do the same. Continue until hole is filled.
Bark mulch is Todd's preference to keep squirrels off bulb beds. Hemlock-Fir 3/4 inch minus (the standard bark mulch at Norgate). They don't like slivers in their faces and hands plus the smell hides the scent of the bulbs.
