Q.
I’m finally having my empty backyard landscaped. It’s the typical subdivision
super hard “soil”. Should it be amended somehow before the new plants
are added? More than just in the hole where the plant goes, I mean.

A. Some of the landscape soils are hard, hard, hard! Wet the area to be planted with an hour of sprinkler water from a hose and sprinkler a few days before digging. This water will help make it softer to dig. I would recommend amending the soil in the planting hole with compost or
another amendment a few days after it is wetted. Amend it between 25 to 33% with compost (one shovelful of compost to 3 or 4 shovelfuls of soil). The hole for the plant should be dug and amended to a width
three times the size of the diameter of the container or roots. Then check it for drainage. The hole should drain water overnight. Wet amended soil should be at least chocolate brown in color.

The hole does not have to be dug
deeper than the container but should be dug three times the root width of the
plants. Amend that soil taken from the hole. The only time the soil needs to be dug deeper than the container is
when the soil is very bad at draining water. If a planting hole is filled with
water and it drains this water overnight, then the drainage is good enough;
three times the width of the roots/container is enough soil preparation.

If the water does not drain from the
hole overnight, you should plant on top of an embankment or a small hill. If
you are planting a medium sized shrub (6 to 10 feet tall) in this spot, then
the soil in the amended mound or hill should be 12 inches tall and about three
or four feet wide. If the tree or shrub is 20 feet tall then the soil mound should be 18 inches high. Cover this soil with a mulch of some sort, either woodchips
or rock depending on the type of plant.
