ON THE CULTURE OF THE TREE ROSE. 7§ 



When the flowers of the Hydrangea hortensis hegin to decay, 

 and the wood sufficiently hard enough to endure the weather, I 

 place the plants out in some convenient part of the garden, where 

 I let them remain exposed till the last week in February, or first 

 week in March, when I proceed to pot them for bloom. The 

 compost I use is what I have grown my Cucumbers in the prece- 

 ding year, which consists of half the quantity of good loam, a 

 quarter of good spit dung from an old Cucumber or Melon bed, 

 and a quarter of decayed leaves. This mixture I lay in the com- 

 post yard for use. The Hydrangeas I bloom in a sixteenth-sized 

 pot : I divest the roots of the old mould. From those plants I 

 intend to produce blue flowers, I cut off* the long fibrous roots, 

 reducing the ball to the size of a thirty-two sized pot. I take one 

 ounce of oil of vitriol, and, with a quill or strong feather, I touch 

 the roots of two plants all over. The remaining oil of vitriol I 

 mix with a sufficient quantity of mould to pot two plants. When 

 I have potted them, I place them in a shed or some sheltered 

 situation for three or four weeks, until they have made new roots; 

 then I place them in a forcing-house, and take especial care not 

 to let them drcop for want of water. The above method I have 

 practised with success for upwards of twenty years. The flowers 

 are equally as large as those that are pink.

 By the early part of April, the stocks will have pushed shoots. 

 When they have grown about half an inch long, or even a little 

 earlier, it will be necessary to look over the stems, in order to rub 

 off all those shoots not required for budding upon. A weakly 

 stock may have one or two left upon it, and a vigorous one three, 

 four, or five. In making choice of shoots, care must he taken to 

 reserve those that are properly disposed : as, for instance, if two 

 shoots, let them be opposed to each other; if three, let them form 

 a triangle; and for a greater number, let them be as near as pos- 

 sible at equal distances from each other, and so as to form the 

 handsomest head. It must be attempted to get all the shoots as
