In 1925, the show was extended to five days from its previous three and ran from 19th-23rd May inclusive. Again the firm were allocated plot I, located on the west side of the Main Avenue and again there was a price increase this time up £10 to £50. Whilst the official measurement of the plot was 40ft. by 30ft. deep, there was at least an additional 5ft. available at the back of the plot where the guide ropes from the tent at the rear were anchored, which the firm intended to use. The layout of the plot and the items displayed were the same as 1924, with the exception that the 6ft. by 4ft. F.3 span-roof plant protector was transposed with the 8ft. by 7ft. No 228 plant protector.
During the show they sold the 12ft. by 8ft. amateur span-roof greenhouse to Mrs. Wedekind, of Caerleon, Claygate, Surrey for £31, together with wood stages to both sides for £4 10s. They also sold the 8ft. by 6ft. F2 2 light frame to Mrs French, of The Garden Cottage, Wellington College, Berkshire for £6 12s. 6d; the 8ft. by 7ft. No. 228 plant protector to F.W. Black, Elizabeth Way, Burnham, Buckinghamshire for £11 10s.; the 12ft. by 7ft. No. 228 plant protector to an existing customer Lionel S. Gooch, of the Boynings, Attwood Road, Maidenhead for £15 10s.. The 20ft. by 16 ft. span-roof greenhouse exhibited at the show was sold, the following February, to Mr. J. Reginald Corah, of Knighton Grange Road, Leicester, a member of the famous Corah firm of hosiery and knitwear manufacturers.
It is difficult to judge the amount of new business the firm created from this show. According to the evidence available, apart from the sales detailed above they received one other order. This was for an amateur 12ft. by 8ft. span-roof greenhouse, with stages and heating apparatus, all unfixed, from a D. Yeoman of Neston, Cheshire. The two parties agreed a 10s discount on the total full show price of £45 10s. (Greenhouse – £31; Stages – £4 10s.; Heating £10). They received a number of requests for estimates, including one on the first day of the show from W. Wells, junior, of the Hardy Plant Nurseries, Mertsham, Surrey for a fixed 20ft. by 16ft. greenhouse on a low brick wall, with No. 2 Loughborough boiler and 3in. pipes, a 150 gallon cistern, stages, etc. Mr. Wells requested that the estimate be ready for when he returned on the afternoon of the 21st. Another estimate was requested from S.S. Moore Ede, of Meadow Wood, Penshurst, Kent for am unfixed 24ft. by 10ft. span-roof greenhouse with 4ft. wide frames, iron stages and loose slatted wood tops on brick base. The fascinating aspect of this query is not the estimate but that he requested advice from the firm on using 220 volt electrical greenhouse heating. Not only does this appear very early to recommend the use electrical heating for horticultural purposes, but one that Messenger’s appear to have no understanding. Amongst the numerous requests for catalogues was one from the Swedish Consul General, interestingly he requested that the catalogue (including the section on conservatories) be sent to him in Birkerød, Denmark.
