In most cases much of a landscape or indoor scape can be planted in edibles. There are some exceptions:
- Local laws and regulations including city ordinances and HOA rules.
- If you are renting and you do not have permission of the landlord.
- In parking strips or other areas where car exhaust and other contaminants may be absorbed into plant tissue and then eaten by you.
- Where soil and/or water is polluted with toxins which may be taken up by the plants.
