☀️ Heat Wave PSA: Is Your Soil Repelling Water?
Helping Your Containers & Hanging Baskets Survive 95°+ Days
When temperatures climb into the mid to upper 90s for several days in a row, even the healthiest hanging baskets and patio containers can suddenly wilt. Many gardeners water them, only to find they still look thirsty an hour later. The problem may not be the plant—it could be hydrophobic soil.
What is Hydrophobic Soil?
When potting soil becomes extremely dry, it can repel water instead of absorbing it. Water runs down the inside of the pot or straight out the drainage holes, leaving the root ball dry while making it look like you've watered thoroughly.
How to Tell if Your Soil is Hydrophobic
💧 Water immediately runs out the bottom of the pot.
🌱 Plants wilt even though you watered recently.
🪴 The soil has pulled away from the sides of the container.
☀️ The top of the soil stays dry or water beads on the surface.
The Fix: Rehydrate Slowly
Instead of watering quickly once, give the soil time to soak it in.
Fill the pot slowly, then wait 5–10 minutes and water again.
Repeat if water continues running straight through.
For severely dried baskets or containers, set the pot in a tub or bucket of water for 15–30 minutes until air bubbles stop rising. Allow it to drain before hanging it back up.
A wetting agent can also help restore extremely dry potting soil.
During Extended 95°+ Heat
Your annuals are working overtime to stay alive.
🌸 Hanging baskets may need watering twice a day—especially those in full sun or under roof overhangs where they receive no rainfall.
🪴 Patio pots often need daily watering and may also require a second drink during extreme heat.
🌿 Check containers every morning and again in the late afternoon.
🚿 Water the soil—not the flowers—and water early in the morning whenever possible.
🌺 Continue fertilizing every 1–2 weeks to replace nutrients that wash out with frequent watering.
A Little Afternoon Wilting is Normal
Many annuals will droop during the hottest part of the day to conserve moisture. If they perk back up in the evening, they're doing exactly what nature intended. However, if they're still wilted after sunset or first thing the next morning, it's time for a deep drink.
The Flower Bin Tip: Lift your pots! A lightweight container usually means the soil is dry. As you get familiar with your containers, you'll quickly feel the difference between a well-watered pot and one that's ready for another soak.
