ROSES UNDER GLASS. 157 



gant in existence to-day, and it is used by most of our 

 large growers. I have proved it so often that I do 

 not care to consider the use of any other fumigant in 

 glass houses, and the house is indeed in a bad way 

 when " Auto-shreds " will not free it of insect pests. 

 As your Roses open avoid spraying the blooms, but 

 spray the floor, pots, and bench to keep a humid atmo- 

 sphere. 



As soon as the blooms are cut or are over remove 

 the trees at once to a cold frame or house to harden 

 off until they can all be safely stood out in the open 

 once more. Summer-flowering Roses, after forcing 

 and hardening off, will give another crop of bloom 

 about May. You must harden off as soon as the 

 forced blooms are over, else, if you allow your trees 

 to start further growth, you will spoil your flowers 

 for next year. Having secured your early Roses, do 

 not forget your trees. These should, after hardening 

 off, be placed back in their old position under a north 

 wall to ripen their wood and recoup for t'heir next 

 season under glass. Top-dress each pot with well- 

 rotted manure, and water regularly. About the first 

 week in October they should all be repotted. Clean 

 all pots, re-crock, and add fresh compost, but do not 

 disturb the soil round the main ball of roots; only 

 rub off the surface soil which may have got soured. 

 Pot up firmly as before and water down ; place the 

 pots in their old position, where they can remain until 

 the end of December; protect against frost, by which 

 time they can be brought into the house, pruned, and 

 forced on as before. 



Climbers under glass require severe pruning, and 

 after flowering plenty of air, hardening them off as 

 best we can under difficulties. They require careful 

 spraying and manuring, and every effort must be made 

 to give them their period of rest before letting them 

 start fresh growth and bloom. 



The growing of Roses planted on benches should 

 here be considered. Benches should be constructed
