OPERATIONS FOR MARCH. 
Annuals, both hardy and tender, must be sown this month. In cold situations 
do not sow the hardy ones till towards the end ; for the mode of proceeding see 
page 18, and for a selection page 22. 
Auriculas must be watered at least once a week with liquid manure : at all 
the other w r aterings at this season use pure water. See page 9. 
Carnations about the end; last year’s layers should be planted off into large 
pots 10 inches wide and 8 inches deep, tilled with a mixture of good rich loam, 
well rotted dung, and sand. 
Currant. The red flowering and other ornamental species may be propagated 
by cuttings in the beginning. 
Camellias. For their treatment see page 33. 
Dahlias. If not already excited, should be plunged in a little heat as early 
as possible. Also sow the seeds, if not done last month. 
Hydrangeas. Put in cuttings of the last year’s wood, which possess plump 
buds ; plant each in a small pot filled with sandy loam and peat. Pot the old 
plants, if not done before. To obtain blue flowers mix about one-twentieth part of 
iron filings in the soil in which the plant is potted. Or mix a portion of sheep’s 
manure with the soil, and water during the spring months with a solution of sheep 
dung and water. 
Ipomopsis. For the treatment of, see page 27. 
Pelargoniums now struck in a hot-bed frame, and potted off as soon as rooted, 
will flower in October. 
Plants in rooms and bulbs in glasses must be treated as recommended below. 
Ranunculuses. Plant all the fine-leaved varieties, if not previously done. 
See page 42. 
Rose Trees in pots, placed in a forcing-house in the middle, will produce 
flowers by the middle of May. See page 23. 
Schizanthus Retusus and other species and varieties, which were sown in the 
autumn, will require shifting into larger pots about the beginning. See page 5. 
Tube roses as recommended last month. 
Tulip Beds should be examined on a fine sunny day, and if any of the roots 
are affected with canker, which will be known by the leaves appearing sickly, take 
off the infected parts, and expose the roots to the effects of the sun and air ; the 
wound will speedily heal. 
MANAGEMENT OF PLANTS IN ROOMS. 
To treat on the proper management of plants in houses is a subject attended 
with considerable difficulty : every genus requiring some variation, both in soil, 
water, and general treatment. If the room where the plants are intended to be 
placed is dark and close, but few will ever thrive in it ; — if, on the contrary, it is 
light and airy, with the windows in a suitable aspect to receive the sun, plants will 
do nearly as well as in a green-house. But if they are observed to suffer, the effects 
may generally be traced to one of the four following causes: — Want of proper light
