There's more to watering your plants than just turning on the hose


As the colder months approach, it’s important to take the necessary steps to protect your plants from frost damage. One common misconception is that watering your plants before a frost can help prevent damage. In this article, we will address some frequently asked questions about watering your plants before a frost and provide you with helpful tips to keep your plants healthy throughout the winter.


1. Should I water my plants before a frost?

Yes, watering your plants before a frost can actually help protect them. Moist soil retains more heat than dry soil, which can provide some insulation for the plant roots. However, it’s important to water your plants at the right time to maximize this benefit.

2. When is the best time to water before a frost?

The best time to water your plants before a frost is during the day, when temperatures are above freezing. This allows the water to soak into the soil and reach the roots before the frost arrives. Avoid watering in the evening or at night, as the water may freeze on the leaves and stems, causing more harm than good.

3. How much water should I give my plants?

It’s essential not to overwater your plants before a frost. Aim for a deep watering, ensuring that the soil is moist to a depth of 6-8 inches. This will provide enough moisture to insulate the roots without leaving the soil waterlogged, which can lead to root rot.

4. Can I use warm water to water my plants before a frost?

Using warm water is not necessary when watering your plants before a frost. The temperature of the water will quickly adjust to the ambient temperature of the soil. However, using ice-cold water should be avoided as it can shock the plants.

5. Should I cover my plants after watering them?

After watering your plants, it can be beneficial to cover them with a frost cloth or an old sheet to provide additional protection. This cover helps trap the heat generated by the moist soil, creating a microclimate that shields the plants from freezing temperatures.

Tips for Watering Your Plants Before a Frost

1. Monitor the weather

Keep a close eye on the weather forecast to know when a frost is expected. This will allow you to plan ahead and water your plants at the appropriate time.

2. Water in the morning

Watering your plants in the morning gives the soil ample time to absorb the moisture and for the excess water to evaporate before nightfall.

3. Use a watering can or a soaker hose

Using a watering can or a soaker hose allows for a slow and even distribution of water near the base of the plants, minimizing water wastage and ensuring that the roots receive sufficient moisture.

4. Avoid watering the foliage

When watering your plants before a frost, focus on the base of the plant and avoid wetting the foliage. Wet leaves can freeze and become more susceptible to damage.

5. Mulch around your plants

Applying a layer of mulch around your plants can help regulate soil temperature and moisture levels, providing additional insulation during frosty nights.

6. Check for drainage

Make sure that your plants are in well-draining soil. Poor drainage can lead to waterlogged roots and increase the risk of frost damage.

7. Don’t forget about potted plants

If you have potted plants, consider bringing them indoors or placing them in a sheltered area to protect them from frost. Water them before moving them to ensure they have sufficient moisture.
