1 Plant needs

Which three inputs are directly used in photosynthesis?

A Light, carbon dioxide, and water B Sand, salt, and sound C Oxygen, plastic, and soil only D Wind, clay, and nitrogen gas only

Why is watering near the root zone usually preferable to wetting leaves repeatedly?

A It delivers water where roots absorb it and may reduce leaf disease risk B Roots never need oxygen C Leaves cannot contact water D It removes all pests

3 Drainage

Why do most container plants need drainage holes?

A To prevent prolonged waterlogging around roots B To stop all evaporation C To make fertilizer unnecessary D To keep roots completely dry

4 Soil

What does soil pH influence?

A Nutrient availability and which plants are well adapted B The length of every day C Only flower color in every species D The direction of gravity

5 Compost

What does finished compost add to soil?

A Stable organic matter and nutrients B Synthetic plastic fibers C Permanent weed immunity D Unlimited water

6 Mulch

What is a common benefit of organic mulch?

A Reduced evaporation and weed emergence B Removal of all soil organisms C Permanent elimination of watering D Instant change of climate zone

7 Transplanting

What does hardening off seedlings mean?

A Gradually acclimating them to outdoor conditions B Removing every leaf C Keeping them permanently dark D Drying roots before planting

8 Propagation

9 Pests

What is integrated pest management?

A Monitoring and combining targeted cultural, biological, physical, and chemical controls B Applying the strongest pesticide on a schedule without inspection C Removing every insect D Ignoring plant health

10 Pollinators

How can a garden support pollinators?

A Provide diverse flowering plants and reduce unnecessary pesticide exposure B Remove every flower C Use only artificial turf D Spray open blooms routinely

11 Crop rotation

Why rotate annual crop families between beds?

12 Plant choice

Why are locally appropriate native plants often useful?

A They are adapted to regional conditions and can support local food webs B They never require establishment care C They grow in every soil worldwide D They cannot spread
