ON CLIMBING PLANTS FOR THE CONSERVATORY AND 

 GREENHOUSE. 



BT CLERICUS. 



I have lately seen a plan recommended of growing the fine new hot- 

 house climbers so as to have them bloom in vigour in a conservatory 

 or greenhouse, by having them planted in a heated pit, constructed 

 behind the conservatory, &c. ; this pit, heated by hot water or fire 

 flue, the stem of the plant introduced through an opening in the 

 back wall, the shoots are easily and regularly disposed, so as to have 

 a fine bloom of these new and beautiful flowers for eight months in a 

 year. At the close of the autumn the stems are readily drawn into 

 the pit, and there secured to have a rest, in a temperature of about 

 45 to 50 degrees. As spring approaches, the pit, with both top and 

 bottom heat, being put into gradual operation, induces the pushing of 

 the buds, and as soon as observed the stems are introduced through 

 the back wall into the conservatory, &c. I have had this plan in 

 successful operation for ten years, and I find that the tenderest hot- 

 house climbers do admirably when the roots are in a proper tempera- 

 ture, the branches grow vigorous, and bloom profusely, with the 

 usual cooler atmosphere of the conservatory and greenhouse. I have 

 had fine specimens^in profuse bloom this summer of Mandevillia 

 suaveolens, Stephanotus floribundus, Allamanda Cathartica, Thun- 

 bergia Hantayneana, Bignonia venusta, Canavalia Bonariensis, 

 Iponwea mutabilis, Ipomsea Learii, &c. I have my plants growing 

 in the heated pit, in a mixture of rotten tan, peat, and loam. I think 

 Bendle's tank system would answer well to heat the soil. I turned 

 out the top of an Ipomsea Learii to train in the open air against the 

 glass end of the conservatory, and it has been an entire mass of bloom 

 since June. I believe the same method will succeed with many 

 other tender plants.
