478 THE GREEN- HOUSE. [JULY 



Some leaves, when employed as cuttings, send out roots and buds at 

 each incision, as in hemionitis palmata, bryophillum, &c. ; d shows 

 how this effect is produced. Time is required to accomplish this, and 

 especial attention must be paid to burying the end of the petiole, or 

 the base of the leaf; e represents theophrasta latifolia, with its leaf 

 cut in two, which struck and developed buds ; the dotted part, shown 

 in the upper half of the leaf, e, was removed, in order to put the leaf 

 into a little pot, but this did not prevent the success of the cutting. 

 The above is abridged from Dr. Lindley's new edition of his "Theory 

 of Horticulture" a indicates at what place we may cut the leaf 

 without hurting the plant ; the leaf being placed in the earth forms 

 a callus at its base, b, whence the roots, and, consequently, more 

 shoots, spring up. 



TRANSPLANTING SEEDLINGS AND CUTTINGS. 



Such seedlings of green-house plants as were raised from the 

 spring sowings, and that are now three inches high, or more, should 

 be transplanted into small pots separately, or several into large pots, 

 and immediately watered ; they must be kept duly shaded till well 

 taken with the earth, and in a growing state ; and even then it will 

 be proper to place them where they can avoid the mid- day sun for 

 the remainder of the season. 



Many of the cuttings planted in spring will be well rooted by this 

 time, and may now be taken up with as much earth as possible about 

 their roots, planted separately in suitable sized pots, and shaded for 

 eight or ten days from the mid-day sun ; always observing to keep 

 the earth in the pots moderately moist. The geraniums in particular 

 may be taken up when too thick, and transplanted at any time after 

 the cuttings have grown four or five inches. 



SHIFTING INTO LARGER POTS. 



You may now shift such of your plants as require larger pots or 

 tubs ; this is the best of the summer months for that purpose, as the 

 greater number will have made their summer progress, and are now 

 rather at a stand previous to the commencement of their new au- 

 tumnal vegetation. This is particularly applicable to the camellia. 



The operation of shifting is to be performed in every respect as 

 directed on page 375. 



Such plants as are now shifted must be immediately watered and 

 removed into the shade, where they can have free air and protection 

 from the sun in the heat of the day j there to remain for two, three, 

 or four weeks, according to the time the respective kinds may take to 

 re-establish themselves, and get into a fresh state of growth, when 

 they may be replaced among the general collection. 



LOOSENING AND GIVING FRESH EARTH. 



It will be very proper at this time to examine the pots and tubs in 

 general, and where the earth is inclinable to bind let the surface be
