A

Remove contaminated surface layer if possible

Line bottom to prevent root penetration & mixing soil

Do not compromise drainage

Cover areas b/w beds to reduce exposure to contaminants via dust & transfer to clothing/footwear

19
Q

what are the advantages of an in-ground garden?

A

inexperience

Efficient use of horizontal space

Makes use of available resources

easier water management

Good when you have good soil, drainage, etc.

20
Q

what are the disadvantages of an in-ground garden?

A

Only as good as the soil, exposure, etc. will allow

may require more work

more difficult to protect from pests

May take time to improve productivity

Q

when terminating grass, why is it disadvantageous to lift & remove the sod?

A

Takes away a productive layer of soil

22
Q

when terminating grass, why is tilling disadvantageous?

A
