What is a good plan to remove and replace the poor soil on our residential lot?
Our lot in Portland is very rocky and very dense. Even with tilling and amendments it does not support plants well.
We intend to remove the top 12 inches of existing soil, and replace it with new soil optimized for ornamentals and edibles (many native species).
With limits on time and money we are thinking maybe:
1) Remove sod and yard debris
2) Remove 12 inches of existing soil
3) "Install" and grade 12 inches of new, improved soil
1) Plant freeze-hardy Cover Crops (to prevent erosion and prep soil for spring)
1) Monitor & maintain cover crops
1) Address winter cover crops
2) Prepare soil
3) Plant edibles and ornamentals (lawns will not - ever - be part of the landscape)
SUMMER 2020 and later
1) Plant edibles and ornamentals
2) Mulch, etc.
3) Maintain plantings and soil
Is ours a good timeline for the project? Are there other steps we are not considering? Thank You!
