NALP Horticultural Tech study plan

NALP Horticultural Tech · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Horticultural Practices & Turfgrass Management

  • Define soil texture classes and explain how cation exchange capacity affects nutrient retention in landscape beds and turf

  • Calculate fertilizer application rates from a soil test recommendation for nitrogen, phosphorus, and potassium

  • Identify the 16 essential plant nutrients and classify each as macro or micro

  • Describe how soil pH alters nutrient availability and list three amendment strategies for acidic and alkaline soils

Your checkpoint

A one-page soil and fertility reference sheet with texture triangle notes, CEC ranges by soil type, and three worked fertilizer rate calculations

Week 2

Horticultural Practices & Turfgrass Management

  • Explain the roles of light, temperature, and water in photosynthesis and transpiration for both ornamentals and turf

  • Diagnose common abiotic disorders (sunscald, chlorosis, drought stress, cold injury) from symptom descriptions

  • Compare irrigation scheduling methods for turf versus mixed landscape beds

  • Outline integrated pest management scouting steps and thresholds for a single common pest

Your checkpoint

A diagnostic decision table mapping 10 symptom descriptions to likely abiotic or biotic causes with corrective actions

Week 3

Plant Identification and Selection & Horticultural Practices

  • Identify 40 woody and herbaceous landscape plants by leaf arrangement, margin, venation, and bud type using a dichotomous key

  • Distinguish native versus introduced species and state one site-condition requirement for each plant on your list

  • Match plants to light, moisture, and soil pH conditions for three distinct site profiles

  • Explain hardiness zone limits and microclimate effects on plant selection

Your checkpoint

A 40-entry plant identification log with botanical name, common name, key ID features, and preferred site conditions

Week 4

Plant Identification and Selection & Landscape Installation and Maintenance

  • Write planting specifications for balled-and-burlapped, containerized, and bare-root stock including hole width, depth, and backfill

  • Sequence the steps of proper tree planting and flag five common mistakes that cause transplant failure

  • Select plant material that meets American Standard for Nursery Stock quality criteria for caliper and root flare

  • Draft a maintenance schedule for the first 24 months after planting

Your checkpoint

A complete planting specification document for one tree and one shrub, including a labeled step sequence and a 24-month care calendar

Week 5

Turfgrass Management & Landscape Installation and Maintenance

  • Compare cool-season and warm-season turfgrass species on growth habit, mowing height, and traffic tolerance

  • Calculate mowing height, frequency, and clipping management for a stated grass species and season

  • Describe aerification, dethatching, and overseeding timing relative to the growth cycle

  • Explain thatch formation and identify the threshold at which remediation is warranted

Your checkpoint

A 12-month turf maintenance calendar for one species with mowing heights, fertilization timing, and cultivation dates justified in one sentence each

Week 6

Landscape Installation and Maintenance & Safety and Equipment Operation

  • Design a planting plan that applies right plant, right place and spacing at mature size for a 500-square-foot bed

  • Specify mulch type, depth, and placement relative to the trunk and explain the risks of overmulching

  • Describe pruning objectives and make the correct cut on a described branch using proper technique and timing

  • List the safety hazards of hand tools and identify the required personal protective equipment for each task

Your checkpoint

A scaled bed plan with plant spacing, mulch specification, and pruning cuts annotated by objective and season

Week 7

Safety and Equipment Operation & Turfgrass Management

  • Perform pre-operation checks and identify the controls and safety interlocks on mowers, string trimmers, and chainsaws

  • Explain kickback causes and chain brake function, and state the safe cutting stance for a chainsaw

  • Interpret pesticide label signal words, reentry intervals, and PPE requirements before any application

  • Describe safe fuel handling, storage, and spill response procedures

Your checkpoint

A machine-specific pre-operation checklist for three pieces of equipment plus a written pesticide label interpretation exercise for two products

Week 8

Horticultural Practices & Plant Identification and Selection & Turfgrass Management & Landscape Installation and Maintenance & Safety and Equipment Operation

  • Complete a timed 100-question cumulative practice set and score each domain separately

  • Re-teach the two weakest domains using your own notes, then re-test those domains

  • Review all four prior deliverables and correct any errors found

  • Build a one-page formula and facts sheet for rates, spacing, and mowing height

Your checkpoint

A scored practice exam report showing per-domain percentages and a prioritized list of the five weakest topics with a remediation action for each

Milestones

Week 2: Score at least 75% on a 20-question self-quiz covering plant physiology and soils, and correctly diagnose 8 of 10 symptom scenarios

Week 4: Identify 35 of 40 plants from your log by key features alone and explain each planting step without notes

Week 6: Produce a turf calendar and bed plan that each pass a self-review against spacing, timing, and safety criteria with no more than two corrections

Week 8: Achieve at least 80% overall on the cumulative practice set with no single domain below 70%
