Once the egg nog starts flowing, our landscaping efforts tend to end with managing leaves. But plants still need our attention, including maintaining moisture levels. Even though it’s winter and they might look dead, the roots are still alive and require water for hydration and insulation. Here are some watering tips to help your plants maintain root strength (especially through freezing temps) and hit the ground running come spring.
Consider Varying Plant Needs
Different plants have different water requirements. Be aware of the specific needs of your plants and adjust watering accordingly. Natives typically require less water.
Monitor Soil Moisture
Check the soil moisture weekly by inserting your finger or a screwdriver near the base; adjust watering accordingly.
Watering Frequency
Plants have reduced water needs during dormancy so water less frequently than you would in the growing season. Once or twice a month during the coldest months is usually sufficient, this includes rain. Don’t over-water!
Water in the Morning
If possible, water early in the day to allow plants time to absorb moisture before temperatures drop at night. This helps prevent frost damage.
Deep Watering
When you do water, make it deep, thorough and infrequent, rather than shallow and frequent to encourage deeper root growth.
Water in the right place.
Focus water at the base of the plant and moisture off leaves and stems.
Mulching
Apply a 2-4 inch layer of mulch around plants to help retain soil moisture and regulate temperature. This is especially important during temperature fluctuations. Avoid piling mulch against the stem.
Protect from Freezing
Watering the soil around plants before a freeze can provide some insulation. Avoid wetting the foliage.
Container Plants
Container plants may need more attention. Ensure they have adequate drainage and move them to sheltered areas during severe cold snaps.
Observe Plant Health
Keep an eye on your plants for signs of stress or overwatering. Adjust your watering schedule based on the health and condition of the plants. Signs of overwatering can be: yellow leaves, wilting, foul or moldy smelling soil, leaf drop, mold and fungal growth, and edema (blister-like bumps on leaves and stems).
