Answers
1
Why is deep tilling a poor choice for preparing soil before planting native plants?
It makes the soil softer, so plants require less irrigation
It destroys soil structure and disrupts fungal networks
It increases beneficial bacteria, which native plants rely on
It improves drainage and helps roots establish faster
2
Which of these native plants provides long-lasting color and pollinator support in commercial landscapes?
Westringia fruticosa
Toyon (Heteromeles arbutifolia)
Myoporum parvifolium
Salvia ‘Pozo Blue’
3
Why might a newly planted nursery-grown plant dry out faster than expected?
It is receiving too much sun
The rootball soil drains and dries out faster than the surrounding soil
It was planted too deep
The plant is too young to absorb water effectively
4
At what PSI do roots stop penetrating soil?
400 PSI
200 PSI
100 PSI
300 PSI
5
Plants with an inverted ET curve need more irrigation in summer to match peak evapotranspiration rates.
True
False
6
What is the best approach when mixing native and non-native plants in commercial landscapes?
Randomly mix native and non-native plants, proportions don't matter
Use mostly non-natives because they require less maintenance
Maintain around 70% natives and 30% non-natives with similar watering needs
Avoid using non-natives entirely
7
What is a key reason to avoid frequent irrigation of native plants?
It prevents the roots from growing deep
It causes powdery mildew
Native plants prefer high humidity
Frequent watering improves drought tolerance
8
Why are native plants better suited for sustainable landscapes?
They support local biodiversity
They grow faster than non-natives
They can survive in any soil type
They need no water at all
9
For native plants, any mulch is better than no mulch!
False
True
10
What is the best way to break up compacted soil before planting?
Using a broadfork to pry open the soil
Augering planting holes, amending, then planting deep-rooted natives
Deep tilling and adding compost
Watering frequently to loosen the soil
11
Which native plant was commonly called ‘Cowboy Cologne’ because riders would rub it on themselves to freshen up?
Satureja chandleri (San Miguel Savory)
California Sagebrush (Artemisia californica)
Black Sage (Salvia mellifera)
Yerba Santa (Eriodictyon californicum)
12
How can soil biology be managed to suppress early-succession weeds?
Encourage fungal dominance by adding wood chip mulch
Disturb the soil frequently to break up weed roots
Increase irrigation to keep plants from drying out
Use nitrogen fertilizers to accelerate plant growth
