In climates with warm winter weather, irrigation will need to continue throughout the winter. Less water is typically required during the coldest months. Follow the LiveWall irrigation chart to adjust the run time and frequency as the temperatures change.
In the event of an occasional freeze, it is important to blow out the irrigation lines an prevent cracks and leaks, and reactivate the system as the weather warms and plants dry out.
Your outdoor living wall’s irrigation system may need to be blown out and reactivated multiple times during the winter months to sustain perennials.
To sustain perennial plants through the winter, the soil must not excessively dry out. The plants in the living wall will not receive sufficient moisture from rainfall due to its vertical nature, and because the planters are exposed, the plants will enter dormancy earlier than the plants in the ground will. Therefore, you will likely need to water your perennial plants before the danger of freezing has passed and typically much sooner than you begin irrigating your at grade landscape.
If the application is planted with perennial plants and it is large, or commercial scale, activate the system as needed – but do so only on warm days where water can flow and drain freely, and only enough to remoisten dry soil. The irrigation system will need to be blown out after each use until the danger of freezing has passed.
If the application is small scale, then wintertime watering can be implemented as indicated above, or simply by using a hand held hose or watering can as the weather necessitates.
