Why Won't My Pumpkin Grow?

Role: Plant Detective

Briefing

The pumpkin patch is failing. Last year it produced wagons full of pumpkins. This year the vines look small, the leaves are pale, and the few pumpkins that started growing turned yellow and fell off. Your job, Plant Detective: figure out what's wrong with the patch and tell the family what to do.

Evidence File

  • EX-01Last year: tall vines, dark green leaves, 14 pumpkins harvested.
  • EX-02This year: short vines, pale leaves, 3 small pumpkins that fell off.
  • EX-03Nobody added compost this year.
  • EX-04The patch has been planted with pumpkins for 3 years in a row.
  • EX-05There is a tall oak tree that grew bigger last summer and now shades the patch in the afternoon.
  • EX-06The dirt looks dry and crumbly even after watering.

Notes for the Parent / Mentor

If you don't have a pumpkin patch, ANY garden bed works — or just use the drawing in their case file. The point is the reasoning chain: clues → suspect → plan. Resist correcting them. A wrong guess defended with evidence is better than a right guess they didn't reason out.
