July in Wisconsin can bring everything from hot, dry spells to sudden, heavy rainstorms. These shifts can stress plants and damage soil. Here’s how to weather-proof your garden to maintain its health and productivity.

1. Improve Soil Drainage Too much rain can lead to root rot and poor plant health.

• Action Steps: Amend garden beds with compost or organic matter to improve drainage and structure. Raised beds are especially helpful in waterlogged areas.

2. Mulch Against Heat and Erosion A 2–3 inch layer of mulch helps regulate soil temperature and moisture.

• Use: Organic mulches like bark, straw, or shredded leaves. These also break down over time, enriching the soil.
• Tip: Keep mulch 1–2 inches away from plant stems to prevent rot.

3. Protect Container Plants Potted plants dry out quickly in heat and can be drowned by downpours.

• Tips: Move containers to shaded areas during heatwaves and check drainage holes to avoid standing water. Use saucers carefully to prevent overflow.

4. Monitor and Adjust Watering Rain might not always mean deep soil moisture.

• Tip: After rainfall, use a soil probe or finger test to check moisture levels. Avoid overwatering which can suffocate roots.
• Dry Spell Strategy: Water early in the morning, 2–3 times per week, deeply enough to soak the root zone.

5. Support Vulnerable Plants Storms can break stems and flatten tall growers.

• Action Steps: Stake tall plants like tomatoes, delphiniums, and sunflowers. Use garden twine or soft ties that won’t damage stems.

6. Harvest Rain Smartly Install a rain barrel to collect and reuse water during dry spells.

• Bonus: It reduces runoff and erosion, and your plants will love the chemical-free hydration.
