It is added, “My house contains a few Pine Apple plants, in the treatment of which I have deviated somewhat widely from the common practice; and I think with the best effects, for their growth has been exceedingly rapid, and a great many gardeners, who have come to see them, have unanimously pronounced them more perfect than any which they had previously seen. But many of the gardeners think that my mode of management will not succeed in winter, and that my plants will become unhealthy, if they do not perish in that season; and as some of them have had much experience, and I very little, I wish, at present, to decline saying more relative to the culture of that plant.” _Hort. Trans._ iii. 465. The above information, the result of Mr. Knight’s experiments in 1819, was communicated to the Horticultural Society in the autumn of that year. On the 7th of March following, a paper was read to the Society on the same plants, of which the following is a transcript: Of those gardeners who doubted whether the plants would stand the winter, it is stated, “The same gardeners have since frequently visited my hot-house, and they have unanimously pronounced my plants more healthy and vigorous than any they had previously seen: and they are all, I have good reason to believe, zealous converts to my mode of culture. “I had long been much dissatisfied with the manner in which the Pine Apple plant is usually treated, and very much disposed to believe the bark-bed, as Mr. Kent has stated, (_Hort. Trans._ iii. 288.) ‘worse than useless,’ subsequent to the emission of roots by the crowns or suckers. I therefore resolved to make a few experiments upon the culture of that plant; but as I had not at that period, (the beginning of October,) any hot-house, I deferred obtaining plants till the following spring. My hot-house was not completed till the second week in June (1819,) at which period I began my experiment upon _nine_ plants, which had been but very ill preserved through the preceding winter by the gardener of one of my friends, with very inadequate means, and in a very inhospitable climate. These, at this period, were not larger plants than some which I have subsequently raised from small crowns, (three having been afforded by one fruit,) planted in the middle of August, were in the end of December last; but they are now beginning to blossom, and in the opinion of every gardener who has seen them, promise fruit of great size and perfection. They are all of the variety known by the name of Ripley’s Queen Pine.
