Key-planting irrigation kit - 19mm

All new gardens have certain key plants, trees and shrubs that would be difficult, costly or disruptive to replace if they die, making them the priority for irrigation. These simple low-cost kits use drippers which, when used in conjunction with an automatic irrigation system, are the most efficient method of delivering the right amount of water to exactly where it is needed. This allows you to focus the available water on priority specimen trees and plants. With built-in pressure compensation, the output of each dripper is balanced at 4 litres per hour regardless of variations in terrain or water pressure - perfect if you are using harvested rainwater or the supply is limited during hosepipe bans. Simply shallow bury the 13mm or 19mm pipework around the perimeter of the garden, then tee off using the 4mm pipe to either a single dripper or string of drippers depending on the amount of water each key plant requires.
