Sales manager Jason Pike said: "Glee was very good for us with more than three weeks of sales volume achieved in just three days.
"As we review already confirmed figures for 2016, we are well ahead year on year for branded product and up on our own targets.
"We anticipated a great take up on the new range and we are in the process of doubling the capacity of our UK stock holding in readiness, but it is great to have our projections confirmed so positively.
"The investment that has gone into the new brand is all about ensuring that the garden retail customer is well supported on and off line, in media and at point of sale. The overall message of our best in class peat to peat-free proposition backed by security of supply and a proactive UK sales team is clearly getting through.
"Our mission is to ensure the consumer can buy the very best performing product whatever the task in hand and whatever their preference in terms of peat and peat-free."
