Timing Is Everything: Why School Gardens Fail Before They Even Begin

You’ve got seeds. You’ve got students. You’ve got a sunny corner by the window or a raised bed outside.
You’re ready to start gardening with your class.

But before you get your hands in the soil, pause.
Because if you don’t consider timing, your school garden might already be in trouble.

As a gardening coach for teachers, I’ve seen the same issue over and over again, not just in one school, but across all grades, cities, and climates. Teachers plant at the wrong time of year, and the result is a frustrating cycle of failed gardens, wasted effort, and missed learning opportunities.

Here’s what you need to know about the role of timing in successful school gardening, and how to finally get it right.

Why Gardening Isn’t Like Other Classroom Projects

In most educational projects, spontaneity is a plus. You get inspired on a Wednesday, print off a worksheet, and dive in on Thursday.
Gardening doesn’t work that way.

Plants operate on seasonal cycles, not lesson plans.
Tomatoes need warmth. Spinach bolts in heat. Seeds don’t germinate if the soil is too cold, or they germinate and then suffer under poor conditions.

A garden project that’s out of sync with the season will either:

• Demand artificial support (like grow lights and indoor systems many schools don’t have)

• Require constant adult intervention to survive

• Or simply die, leaving students confused and disheartened

This isn’t just a logistical error—it’s a missed educational opportunity. Because when a garden fails, we lose more than plants. We lose student engagement, inquiry, confidence, and the sense of accomplishment that hands-on learning provides.

Real-World Mistake: The Fall Semester Seedling Trap

Let me share a true (and far too common) example.
Last fall, my own daughter’s high school science class planted tomatoes, pumpkins, basil, and corn—in October. Indoors.
The kids were excited. The seeds sprouted. There was some basic learning about germination.

But then came December. The plants were leggy and struggling at the windowsill, winter break was approaching, and the teacher had to decide:
Take them home? Let them die? Throw them out?

In the end, most were composted or tossed.

Yes, the students got to see some growth. But what did they really learn? That we grow things only to discard them when school gets busy? That nature can be controlled to fit our academic schedule?

It’s a tough but important question.

Why Timing Matters Even More in School Gardens Than Home Gardens

In a home garden, you can tweak timing, experiment, or even recover from mistakes. But school gardens are different. They’re limited by:

• The school calendar

• Long summer breaks

• Shared maintenance responsibilities (or lack thereof)

• Fixed classroom schedules

• Budget and infrastructure limits

This means that timing is not just “important.” It’s mission-critical.

Start too early, and your plants will mature in the summer when no one is there to harvest.
Start too late, and they won’t reach maturity at all.
Start indoors in winter with the wrong crops, and they’ll survive just long enough to fail.

When I designed my Oasis programs, timing became the backbone. Every lesson, task, and planting suggestion is seasonally aligned. And still—even with everything mapped out clearly—teachers would sometimes start in the wrong month, with the wrong plants, and ask why it wasn’t working.

It’s not that they didn’t care. It’s that timing is always underestimated.

The “Let’s Build a Garden in May” Problem

Another all-too-common situation:
A school team finally secures funding and a passionate volunteer to help build a garden, and they reach out to me in late May or June wanting to get started immediately.

The intention is wonderful. The motivation is strong.
But the season is all wrong.

In most climates, building and planting in late spring means your first real harvest will hit in July or August when no one is at school to see it. And without students there to tend or harvest, that garden often becomes a burden: overgrown, under-maintained, and ultimately forgotten.

It’s not a “bad garden.”
It’s just bad timing.

What Good Timing Looks Like

So how do you get it right?

1. Align with Your Academic Calendar

   • Spring semester: Focus on crops that mature by end of school year (e.g., lettuce, radishes) or on the other side of summer, not during!

   • Fall semester: Plant in September only if you can finish the harvest by November, or focus on indoor herbs and sprouts or activities such as seed stratification.

   • Avoid launching planting projects in winter unless you’re doing microgreens or sprouts.

2. Choose Plants Based on Seasonality, Not Excitement

   • Tomatoes sound fun, but they need a long, warm season and lots of sun.

   • Cool-season crops like lettuce and spinach work better for spring and won't do well in summer.

3. Plan Ahead for Summer Maintenance, or Avoid It Entirely

   • My free guide [School Gardens with Almost No Summer Maintenance] walks you through exactly how to plan for this.

   • The key is not planting things that mature in summer unless you have a plan for that harvest.

4. Be Strategic, Not Spontaneous

   • Spontaneity is great in teaching, but in gardening, strategy wins every time.

Final Thoughts: Let’s Respect the Rhythm of Nature

I know how hard teachers work.
I know the intention behind every planting project is beautiful.
But I also know that nature doesn’t bend to our lesson plans.

When you align your garden with the seasons, you don’t just get better plants, you get better learning. Your students experience success. They taste what they grow. They feel the power of working with nature, not against it.

And most importantly:
You stop feeling like your school garden is a burden.
It becomes what it was always meant to be an inspiring joyful extension of your classroom.
