A Kent and Stowe-branded range of "top-end garden tools at mid-range prices" is also new from Crest, as is the 'Flopro' watering range of hoses, fittings and spray guns.
Crest is backed by Westland and is run by former Solus managing director Nick Davies. The propagation products will be marketed exclusively under the ‘Plantpak by Crest’ brand name.
The range will include traditional Plantpak retail products such as seed and gravel trays, propagators and plant pots together with several new additions including heated propagators and plant raising kits.
The joint venture will combine the technical and production departments of Desch Plantpak with the sales and marketing staff of Crest Garden.
Commenting on the joint venture, Chris Clarke, managing director of Desch Plantpak said: "The co-operation with Crest Garden will combine a number of well known brands into an offering tailored to inspire gardeners."
Crest Garden managing director Nick Davies said: "This is a strategically attractive venture for both parties. Plantpak is a respected brand in the UK horticultural industry with a long tradition of manufacturing for the professional and amateur markets. Crest Garden has the resources and expertise to ensure that the products are available to an even larger number of retail garden outlets."
The new Plantpak by Crest range will be launched at Glee (NEC), September 14-16, Hall 19 Stand H23.
