96 OPERATIONS FOR MAY. 
remain, until frosty nights render it necessary to afford them protection. Tender 
annuals that have been raised in small pots, in the nursing- pit or frame, should 
now be gradually exposed to harden them, or they will suffer when planted out, 
which should speedily take place. 
Attention will now be required amongst alpine plants, &c. ; where these occupy 
places in rock-work, many points should be attended to, such as examining the soil 
about the roots, making them firm, thinning where too thick, introducing new kinds, 
clearing off seedhng weeds which will now be showing in abundance, and setting all 
fair and in a manner that will do credit to the whole. 
Annuals of various sorts to succeed those sown last month should now be 
put in. 
Camellias should now be potted, the soil for this purpose should consist of 
«qual parts of loam and peat, to which may be added a little well pulverised dung ; 
after potting they should be placed in a peach-house or vinery in order to excite 
the growth of their shoots, bearing in mind to syringe them now and then over the 
leaves and branches. Vol. 1, page 33. 
Cf,rM[3iNG PLANTS, whether in the green-house, stove, or flower-garden, will 
now require attending to, the superfluous shoots cut out, and the others tied in. 
Dahlias (seedlings) should be planted out in some unfrequented place where 
they can be proved when in bloom ; old plants may now be turned out into the 
borders, &c. 
Greenhouse plants, where it is customary to expose them by forming clumps 
of them in the flower-garden, &c., may in the early part of this month be taken out 
without fear from frosts, &c. ; a sheltered situation is preferable for them. 
Herbaceous plants (early flowering kinds). If cut down as soon as the 
Howers have faded will very often produce a second time a display of blossoms in 
the autumn. Much advantage would be gained if the attention of practical men 
were turned to this point. 
Nelumhiums, Plumieriay Euryale, Pontederia, and other aquatic plants, should 
now have great attention. Keep them free from insects, and allow plenty of room 
for both roots and leaves ; a frequent change of water will be beneficial for them. 
Vol. 2, page 110. 
Propagate Salvias, Verbenas^ and any desirable species or variety of plants, 
remembering to shade the cuttings from the influence of the sun, and carefully 
water them. 
Primulas (seedlings), if not potted off, let it now be done without delay, using 
60 sized pots ; if older plants, encourage them to flower ; they flower well in 32 sized 
pots, any rich hght soil will suit them. Vol. 1, page 181. 
Rhodochiton voluhile, Lophospermum erubescens, will do very well, trained 
against a south wall ; provided they are planted in a good border, and the situation 
be sheltered, they may now be put out. 
Succulents. — Offsets of this curious family may now be taken and propagated 
if not previously done. Give plenty of air to old plants, in short to all dry stove 
plants ; be very guarded in watering them, for they are very tenacious of this ele- 
ment. Vol. 2, page 27.
