70 GREENHOUSE MANAGEMENT. 



up and potted by the first of August, and will need 

 about the same attention as the plants that have not 

 been planted out. 



STAKING THE POT PLANTS. 



All pot plants should be provided with a center 

 stake, or wire rod, to which the main stem should be 

 tied, and bush plants will need from three to seven, in 

 order to keep the side shoots in place, and prevent them 

 from breaking down. When perfect plants are desired 

 for exhibition purposes, considerable attention is given 

 to the training of the plants. Commencing at the time 

 of the second pinching, the side shoots should be drawn 

 into place and held there with loops of raffia. When 

 pinched the next time, hoops or rings of wire can be 

 fastened to the stakes, and the laterals can be tied to 

 them. With large plants, a second, and even a third, 

 ring will be found useful. 



LIQUID MANURE. 



As soon as the plants have become established in 

 the beds, they should receive applications of liquid 

 manure once a week until the flowers open, and the pot- 

 grown plants will need this treatment, commencing the 

 first of July. It is also well, as soon as the weather 

 becomes hot and dry, to mulch the plants in the beds 

 with an inch or so of cow or sheep manure, which will 

 both hold the moisture and supply food for the growth 

 of the plants. As the flower buds develop, there is par- 

 ticular need of liquid manure, and if furnished freely it 

 will increase the size and perfection of the flowers. 

 When the buds open, and during the period of flower- 

 ing, no manure should be given them, and great care 

 should be taken in watering the plants. 



VARIETIES AND THEIR CLASSIFICATION. 



The work of crossing the varieties has been carried 

 so far that it is hard to tell where one class ends and
