Where to Grow Plants: Suitability

Aspect

Is the site sunny or shady and at what time of day? Sunny sites are better for growing the widest range of plants. Where does the sun rise and set? Identify north. What plants do/might cast shade and when? Can plants be sheltered, eg with windbreaks such as hedges?

Site history

Are there known diseases or persistent weeds in the soil that may affect new plants? Were fruit and vegetables grown on site before? Avoid growing the same crop in the same place year after year (use 

crop rotation).

Soil condition 

Is the soil suitable for growing, eg fertile, not too compacted, moist but free draining? Even very poor soil can be improved given time.

Existing plants 

What existing plants or weeds could benefit or harm new planting? Native hedgerows attract wildlife, for example, but dry out soil and cast shade.
