A soul-rooted guide to resetting your soil using nothing but sunlight, intention, and a little time
🌿 Opening Reflection: Let the Sun Do the Work
There’s something humbling about letting the sun take over your garden for a season. No planting. No watering. No work—except the quiet work of waiting.
Solarizing a garden bed has always felt a little counterintuitive to me. I’m a grower by nature. But this year, I found myself standing before a bed that just wouldn’t thrive. The soil was tired. Weeds took over. Pests came back again and again. It was time for rest—but not passivity. It was time for solarization.
Like Sabbath for the soil, solarizing clears out what you can’t see. It uses the summer sun to cleanse, correct, and create space for what’s next. It’s an act of faith—and one of the most natural tools we have for preparing beds for the season to come.
🌞 What Is Solarization?
Soil solarization is the process of covering a garden bed with a clear plastic sheet for 4–8 weeks during the hottest part of the year. The heat generated beneath the plastic raises the soil temperature enough to kill:
- Weed seeds
- Soil-borne pathogens and fungi
- Root-knot nematodes
- Certain insect larvae
This method works best during peak summer, when temperatures are consistently above 85°F, and sunlight is direct for 6+ hours a day.
✨ Think of it as a natural cleanse—no chemicals, no tilling, just the quiet power of the sun doing what it does best.
🧠 When and Why to Solarize
Signs You Might Benefit from Solarization:
- Persistent soil-borne diseases like fusarium or verticillium wilt
- Recurrent weed problems, especially bermudagrass or nutgrass
- Beds that feel depleted, crusted, or tired despite amendments
- Transitioning a lawn or weedy patch into a new garden bed
- Preparing beds for fall planting, especially for cool-season greens
Southern Timing (Zones 8–10):
- Ideal window: late June through August
- Let it cook for 4–6 weeks, or up to 8 for tough weed issues
🧰 What You’ll Need
| Tool | Why It Matters |
|---|---|
| Clear plastic sheeting (1–4 mil) | Allows UV rays to penetrate |
| Garden staples or landscape pins | Secures edges to trap heat |
| Hose or watering can | Soil must be moist before covering |
| Timer/reminder system | Keeps track of how long it’s been covered |
| Patience | It’s slow work—but powerful |
⚠️ Important: Use clear, not black or opaque, plastic. Black plastic will block sunlight and act as a mulch—not as a solarizer.
✨ Step-by-Step: How to Solarize Naturally
1. Prepare the Soil
- Pull weeds and remove large plant debris
- Rake the bed as flat as possible
- Water the soil deeply (to about 12″ depth)
2. Lay Down the Plastic
- Use a single sheet of clear plastic
- Secure the edges tightly with staples, bricks, or bury them in a shallow trench
- Press out air pockets where possible for direct soil contact
3. Let the Sun Work
- Leave the bed covered for at least 4–6 weeks
- Avoid disturbing it—let the heat build consistently
- Check edges every week for gaps or movement
4. Remove & Rest
- After your chosen solarization period, remove the plastic
- Let the soil air out for 1–3 days
- Top with compost or amendments if needed
- Plant your fall crops—or let the bed rest a bit longer
🌿 What to Plant After Solarizing
Once solarization is complete, your bed will be primed for fresh growth.
Great follow-up crops:
- Leafy greens: lettuce, spinach, chard, kale
- Brassicas: broccoli, cauliflower, cabbage
- Root veggies: beets, carrots, radishes
- Flowers: calendula, alyssum, nasturtiums for fall pollinators

✍️ How Solarization Reflects a Garden Soul
Letting the sun do the work isn’t lazy. It’s intentional.
Sometimes we need to stop digging. Sometimes the best thing we can do is clear a space, cover it in grace, and let light and time do the healing.
What if the season that feels empty is just solarization for your soul?
Questions to ask as you solarize:
- What old weeds have taken root in me?
- What do I need to bring into the light?
- Where am I being invited to rest—so I can grow again?

You don’t have to fill every bed, every day.
