The nursery invested £25,000 in the system and has seen sales in its transplants division up 10 per cent compared to the 2012/13 season.
Transplants division production director Ray Jenkins said: "The transplants division has been a major part of Wyevale Nurseries for 27 years and it has been particularly successful in our more recent history.
"However, we recognised that to remain an industry leader we needed to invest. I’ve worked in the Transplants Division for more than 25 years and some of the crops we have produced this year are undoubtedly the best I’ve seen.
"This is great for us and great news for our customers, and having a new irrigation system has greatly assisted with this as it has given us much better control of our watering.
"In total 3,500 metres of pipe was laid for the new irrigation system across 15 acres of seed raised hedging and forestry."
Wyevale Nurseries has also recently invested in a cold store with full humidity control for care of its crops and to help extend the availability of bare root transplants.
The nursery is in the process of purchasing another field lifter, which is the first of its kind in the UK, to help ensure stock can be lifted quicker to meet the high service levels the company has set.
The nursery grows 1.7 million two-year-old transplants and a quarter of a million three-year-old transplants.
