He said: "Job changes will take place. There will be one or two changes to key staff as I take on the managing director's role."
Eady stressed it would be very much "business as usual" at the firm, which "remains profitable".
Former owner Peter Wood told HW he sold up because the business needed a fresh look and he wanted a new challenge.
Neither party disclosed the price of the sale but an industry source suggested it could have been in the region of £6m-£10m. Eady raised the funds from private investors.
Wood said: "I am delighted that the business has been sold to Wayne. He has been with the company for 12 years, which will ensure continuity at all levels of the business. I'm sure his energy and enthusiasm will help the business flourish even more than before."
Wood stated he will stay on for "as long as they need me". He will take on a consultancy role, aiding the transition and focusing on key accounts, trials and research and new product development.
The company produces more than 100 million plants yearly and annual sales reached £8m in February 2007. Eady reported that the company's introduction of online sales two years ago has led to five per cent growth in sales, while advertising on satellite TV channels has added 15 per cent.
