274 GREEN-HOUSE FLOWERING STOCKS. [April. 



INSECTS. 



Insects will, on some plants, be very perplexing. The 

 weather may admit of those that are infected to be taken out 

 of doors, and put into a frame in any way that is most con- 

 venient. Fumigating them about fifteen minutes, if the 

 day is calm, will be sufficient ; but if windy, they will take 

 half an hour. When done, syringe them well, and put 

 them in their respective situations. By the above method, 

 the house will not be made disagreeable with the fumes of 

 tobacco. 



Tie up neatly all the climbing plants. Keep those that 

 are running up the rafters of the house close to the longi- 

 tudinal wires. As previously observed, running plants 

 should not be taken across the house, except in some in- 

 stances where it can be done over the pathway, otherwise 

 it shades the house too much. Clear off all decayed leaves 

 and all contracted foulness, that the house and plants may 

 in this month have an enlivening aspect, as it is undoubt- 

 edly one of the most interesting seasons of the year in the 

 green-house. 



FLOWERING STOCKS. 



Those that have been kept in the green-house, or in 

 frames, should be planted into beds or the borders, where 

 they will seed better than if kept in the pots. The method 

 generally adopted is, to select the plants that are intended 

 for seed ; plant the different kinds distinctly and separately ; 

 then take a few double flowering plants of each kind, which 

 plant round their respective single varieties that are to be 

 kept for seed. Whenever any of the colours sport, that is, 

 become spotted or striped with other colours, plant such by 

 themselves, for they will soon degenerate the whole, and 

 ought never to be seen in collections that have any preten- 

 sions to purity. Many have been the plans recommended 

 as the best for saving and growing from seed the double 

 varieties of German stock. In every method we have 

 tried we have been successful and unsuccessful ; although 

 we generally practise planting the Double kinds beside the
