Water conservation efforts are needed in zone 4, the lack of inadequate snow and rainfall has triggered drought like conditions and we are in need of creative measures to keep our gardening schedule on course. Installing a drip irrigation system is one way to keep a garden green during a drought season. This type of watering system will reduce the evaporation of spray unlike an overhead watering style system and discourage the spread of disease while watering your soil with pin point accuracy. A drip system keeps soil moist with the least amount of water waste. The system is affordable and adaptable to any garden scenario. Cheers
