Drip irrigation tubes can focus the water to each plant. Using the Pot-in-Pot method you can focus less water directly into the pot with very little waste and optimize the performance of your plants.
Roses do particularly well with drip irrigation since they are less prone to disease if the foliage stays dry.
Drip irrigation in raised planter beds makes watering easy and efficient.
Our container production benefits from drip tape irrigation by keeping the foliage dry, saving water and fertilizer and allowing us to water all the plants only when they need it.
