Study Guide: Alex for Horticulture & Landscaping Students

Your reference for applying AI to landscape design, plant selection, pest management, client proposals, and green industry business development. Ready-to-run prompts — built for the science and business of growing things.

What This Guide Is Not

This is not a habit formation guide (see Self-Study Guide for that). This is a domain use-case library — how AI supports your horticulture education and green industry career.

Where to Practice These Prompts

Every prompt in this guide works with any AI assistant — ChatGPT, Claude, GitHub Copilot, Gemini, or whatever tool you prefer. The prompts are the skill; the tool is just where you type them. Pick the one you’re comfortable with and start today.

For an integrated experience, the Alex VS Code extension (free) was purpose-built for this workshop.

Core Principle for Horticulture & Landscaping Students

You work with living systems that don’t read textbooks. Plants respond to soil, light, water, temperature, and each other — and your job is to understand those relationships well enough to create landscapes that thrive, not just survive the first season. AI helps you with the knowledge side — plant identification, pest diagnosis, soil analysis, and the business of proposals and estimates — so your time in the field is more productive and your decisions are science-based.

The Seven Use Cases

1. Plant Selection and Design

The horticulture student’s selection challenge: Choosing plants that look good together is easy. Choosing plants that thrive together — in the specific soil, light, moisture, and hardiness zone of the site — while meeting the client’s aesthetic and maintenance expectations is the real skill.

Prompt pattern:

I am designing a [project type: residential landscape / commercial planting plan / garden bed / container installation / restoration planting].
Site conditions: [hardiness zone, sun exposure, soil type, moisture, existing plants, microclimate factors].
Client needs: [aesthetic preferences, budget, maintenance level they're willing to do, wildlife/pollinator goals, privacy/screening needs].

Help me:
1. Recommend a plant palette that works together ecologically — not just visually
2. For each plant, note: mature size, light/water needs, seasonal interest, maintenance requirements
3. Identify potential problems — invasive tendencies, disease susceptibility, deer browse, allelopathy
4. Create a planting plan with spacing and grouping rationale

Follow-up prompts:

The client wants [specific plant] but the site conditions are wrong for it. Suggest alternatives that give the same effect in conditions that will actually support them.

I need a four-season interest plan for this bed. Walk me through what's blooming, fruiting, or providing texture in each season.

This design uses 12 species. Am I over-diversifying or under-diversifying for the scale? What's the design principle for species count at this scale?

2. Pest and Disease Diagnosis

The horticulture student’s diagnostic challenge: A yellowing leaf could be overwatering, nitrogen deficiency, root rot, spider mites, or herbicide drift. Diagnosis requires systematic observation — not jumping to the first pest you can name. The student who can diagnose accurately recommends the right treatment and avoids unnecessary chemical applications.

Prompt pattern:

I'm observing [symptoms] on [plant species/type].
Location: [garden, nursery, greenhouse, landscape].
Environmental conditions: [recent weather, irrigation, soil conditions, fertilizer history].
What I see: [describe symptoms specifically — pattern, color, location on plant, progression].

Help me:
1. Build a differential diagnosis — what are the possible causes ranked by likelihood?
2. What additional observations would narrow the diagnosis? (What should I look at more closely?)
3. For the most likely diagnosis, what is the recommended IPM approach? (cultural, biological, chemical — in that order)
4. What would a wrong diagnosis lead me to do that would make the problem worse?

Follow-up prompts:

I think this is [pest/disease] but I'm not sure. What would confirm it vs. rule it out? Give me the specific diagnostic sign.

The client wants me to "just spray something." Walk me through the IPM conversation — why we diagnose first and how I explain that to a homeowner.

This pest has been resistant to [treatment]. What's probably happening and what's the next step in the management plan?

3. Landscape Estimation and Proposals

The horticulture student’s business challenge: A landscape is a product and a service. Estimating materials, labor, and maintenance costs — and presenting that as a professional proposal — wins contracts. The student who can estimate accurately is the one who’s trusted with bigger projects.

Prompt pattern:

I need to estimate / propose [project: installation / maintenance contract / irrigation / hardscape / planting].
Scope: [dimensions, plant list, hardscape materials, site prep required].
Location: [for labor rate and material pricing context].

Help me:
1. Build a detailed materials list with quantities (plants, soil amendment, mulch, hardscape materials, irrigation components)
2. Estimate labor hours by phase — site prep, installation, cleanup
3. Calculate pricing that covers costs and is profitable — don't forget overhead, disposal, and travel
4. Draft the proposal in a format the client can understand and sign

Follow-up prompts:

The client's budget is $5K below my estimate. Help me design a phased installation plan — what goes in now, what waits for phase 2?

How do I price a maintenance contract? I need a monthly rate that's fair and profitable for [property type and size].

My estimate for mulch seems off. Walk me through the volume calculation for [bed dimensions and depth].

4. Soil Science and Site Analysis

The horticulture student’s soil challenge: Soil is the foundation of everything. A beautiful plant in bad soil is a dead plant walking. Understanding soil tests, amendments, drainage, and the relationship between soil and plant health separates professionals from plant-shoppers.

Prompt pattern:

I have soil test results from [site]: [pH, organic matter, N-P-K, CEC, sodium, other relevant values].
Intended use: [planting beds, lawn, vegetable garden, native restoration].
Current condition: [what I observe — compaction, drainage issues, erosion, existing vegetation].

Help me:
1. Interpret these results — what's this soil good at and what's it lacking?
2. Recommend amendments — what to add, how much, and application method
3. Identify which plants will thrive in this soil vs. which will struggle
4. Flag any concerning values and explain what they mean for plant health

Follow-up prompts:

My pH is [value] and I want to grow [plants]. What's the amendment plan and how long until the pH shifts?

The site has heavy clay and poor drainage. What are my options — amend, install drainage, or design with it? Compare the approaches.

How do I explain a soil test to a homeowner who just wants to know "why are my plants dying?" Translate the numbers into plain language.

5. Irrigation and Water Management

The horticulture student’s water challenge: Efficient irrigation is increasingly important — water costs money, drought restrictions are common, and overwatering kills more plants than underwatering. The student who understands irrigation design and water management is designing for the future of the industry.

Prompt pattern:

I need to [design / troubleshoot / audit] an irrigation system for [landscape type].
Site: [area, zones, plant types, water source, pressure].
Goals: [efficiency, uniformity, water budget, drought tolerance, code compliance].

Help me:
1. Design zone layout based on plant water needs (hydrozone principle)
2. Select appropriate heads/emitters for each zone with spacing calculations
3. Calculate the water budget — gallons per zone per week based on ET and plant factors
4. Identify inefficiencies in the current system (if auditing) and recommend improvements

Follow-up prompts:

Walk me through precipitation rate calculation for this zone. I need to make sure I'm not over- or under-applying.

The client wants to convert from spray to drip on [bed]. Help me design the conversion — emitter placement, flow rates, and runtime.

We're under watering restrictions. Help me design a drought-tolerant landscape that still looks intentional, not neglected.

6. Sustainable and Ecological Practices

The horticulture student’s sustainability challenge: Native plantings, pollinator gardens, rain gardens, green infrastructure — the industry is shifting toward ecological design. The student who understands these practices has a competitive advantage and a career aligned with where the market is heading.

Prompt pattern:

I want to incorporate [sustainable practice: native planting / rain garden / pollinator habitat / composting / organic management / green roof / permeable paving] into [project].
Site conditions: [relevant environmental factors].
Client motivation: [environmental values / stormwater management / wildlife / aesthetics / regulatory requirement].

Help me:
1. Design the ecological feature according to best practices (sizing, plant selection, soil spec, grading)
2. Explain the ecological function — how does this work and why does it matter?
3. Calculate the environmental benefit (stormwater volume managed, pollinator species supported, etc.)
4. Write the client-facing description — sell the value in terms they care about

Follow-up prompts:

Design a rain garden for [area and soil type]. Include sizing calculation, plant list, and soil mix specification.

I'm proposing a native vs. conventional landscape. Help me build the comparison — installation cost, maintenance cost over 10 years, ecological value, and aesthetic.

7. Career and Certification Planning

The horticulture student’s career challenge: Horticulture careers span landscape design/build, nursery/greenhouse management, arboriculture, golf course management, public gardens, urban forestry, pest management, and landscape architecture. Certifications (ISA, CLT, CPH) open doors and raise income.

Prompt pattern:

I'm interested in a career in [horticulture specialization].
My current status: [student, working, transitioning].
Certifications I'm considering: [ISA Certified Arborist / CLT / Master Gardener / Licensed Pesticide Applicator / CPH].

Help me:
1. Map the career path from where I am to where I want to be
2. Which certification should I pursue first and what does it require?
3. What practical experience sets me apart from other applicants?
4. What does the industry look like in 5 years? Where is the growth?
