Before putting a plant in the ground, a gardener needs to research what that plant requires and what methods are available for growing it. This lesson covers how to conduct that research.
Assumed audience
- Reading level: general adult.
- Background: has completed the lessons on plant basics, soil, light and climate, and propagation methods.
- Goal: be able to gather enough information about a plant and a place to make an informed decision about how to grow the plant there.
Why research comes first
Skipping research leads to wasted effort: a plant placed in the wrong conditions or grown with the wrong method may fail to thrive or may require far more intervention than necessary. Research is the lowest-cost step in gardening and has the highest return.
What to research about the plant
- Species and cultivar requirements: light, water, soil pH, nutrient needs, temperature range, and spacing.
- Growth habit: annual, perennial, biennial; vining, bushy, upright.
- Propagation method: seed, transplant, cutting, division, or tuber.
- Timing: when to start seeds, when to transplant, days to maturity, and frost sensitivity.
- Common problems: pests, diseases, and environmental stresses that affect this species.
What to research about the place
- Hardiness zone: the USDA plant hardiness zone or equivalent regional classification for your area.
- Microclimate: sun exposure, wind patterns, frost pockets, heat reflected from buildings or pavement.
- Soil: texture (sand, silt, clay), drainage, existing pH, and organic matter content.
- Water availability: rainfall patterns, irrigation access, and any water-use restrictions.
- Space constraints: available area, vertical space, container options, and proximity to other plants.
Where to find reliable information
- Cooperative extension services: university-affiliated programs that publish regionally specific growing guides.
- Seed catalogs and seed packets: provide cultivar-specific information on spacing, light, and days to maturity.
- Regional gardening organizations: local knowledge about what grows well and when to plant.
- Published growing guides: books and reference materials organized by region or plant family.
- Experienced local growers: neighbors, community garden members, and farmers market vendors who grow in similar conditions.
Organizing your research
For each plant you intend to grow, record:
- The plant’s key requirements (light, water, soil, temperature).
- Your site’s conditions for each of those requirements.
- The gap between what the plant needs and what the site provides.
- The methods available to close that gap (amending soil, providing shade, using containers, starting indoors, etc.).
This record becomes the basis for selecting a growing method in the next lesson.
