Why Won't My Pumpkin Grow?

Role: Plant Detective

Briefing

Scholar, your task is bigger. A 1/4-acre family garden is good for one year — but in 3 years the soil will be exhausted and the same plant families will start attracting disease. Design a 9-month, multi-bed plan that includes succession planting, crop rotation across seasons, soil amendments, and a real yield budget. Include cost-benefit numbers: dollars spent vs. dollars worth of food produced.

Evidence File

  • EX-01A family of 4 needs roughly 200 lbs of vegetables per year for full self-sufficiency.
  • EX-02Crop rotation prevents disease: don't plant the same plant FAMILY in the same bed two years running. (Tomatoes, peppers, potatoes, eggplant = same family.)
  • EX-03Soil tests cost $15–$25 and tell you exactly what nutrients to add.
  • EX-04A 4x8 raised bed costs ~$80 in lumber + ~$60 in soil and compost to build.
  • EX-05An average $1 of seeds produces $20+ in vegetables if the season is managed well.
  • EX-06Succession planting (replanting beds after early harvests) can produce 2–3 crops per bed per year.

Weekly Milestones

  1. Day 1
    Get a real soil test of your site (kit or extension service). While waiting, sketch the existing site to scale.
  2. Day 2
    Build a 9-month planting calendar — what goes in each bed, what month, what comes out, what replaces it.
  3. Day 3
    Lay out a 3-year crop rotation table for plant families across all beds.
  4. Day 4
    Build a yield budget: estimated lbs harvested + estimated $ value vs. estimated $ cost (seeds, soil, supplies).
  5. Day 5
    Write a 1-page proposal to the family with the plan, costs, and projected return.

Your Deliverable — Scholar

Ages 11–14

1-page proposal with scaled garden plan, 9-month succession calendar, 3-year crop rotation table, and yield-vs-cost budget.

Other tracks tackle this same case at their own depth — see the catalog.

Rubric

Soil data

Plan responds to a real soil test (or documented assumptions if no test available).

Succession

Every bed produces at least 2 crops in the 9-month plan.

Rotation

No plant family repeats in the same bed across 3 years.

Economics

Yield budget shows $ income vs. $ cost with at least 3 line items each.

Proposal

Reads like a real document a parent could act on.

Badge

Scholar — Garden Steward

  • Soil test (or documented baseline) submitted.
  • 9-month calendar + 3-year rotation table submitted.
  • Proposal presented to and discussed with a parent.

Notes for the Parent / Mentor

This mission asks your scholar to think like a small-business owner, not just a gardener. The numbers matter as much as the layout. If they can defend the budget, they're ready.
