prevent the attacks of red spider.

Mushrooms.—An abundance of water to be thrown about the floors. If the beds are dry, to be syringed with lukewarm water, applying it like dew at intervals for a few hours. Temperature from 50° to 60°, with air occasionally in favourable weather.

Peaches.—Continue previous directions. The trees in bloom to be artificially impregnated, and the foreright shoots to be rubbed off a few at a time before they become too large. Currents of air to be carefully avoided, especially when the trees are in bloom, as they have been sometimes observed to sustain injury from the two end doors being left open for a short time. Air to be given at the top daily in favourable weather.

Pines.—As the days lengthen and the light increases the plants that are swelling their fruit should be supplied with a gradual increase of heat (from 65° at night to 75° or 80° in the middle of the day in clear weather), water, and atmospheric moisture; while others that are in bloom and starting into fruit require more air or more moderate temperature, care in watering and less atmospheric humidity. Some of the strongest succession plants that are grown in pots to receive their final shift, that they may make their growth for fruiting in May or June. In old-fashioned pits or houses, where the flues run near the tan-bed, the plants should be closely examined, as they are apt to be injured by fire heat in such a situation.

Strawberries.—A few dozens more pots may be placed in a frame where there is a gentle heat and an atmosphere more congenial to their healthy growth than in a house.

Vines.—When they have made shoots two or three inches long, the night temperature to range from 60° to 65°, with an increase of from 5° to 10° during the day.

PITS AND FRAMES.

Keep the plants in these structures as hardy as possible by fully exposing them in mild weather, but do not give any more water than is absolutely necessary. Remove all decayed and decaying leaves, and keep the atmosphere in as healthy a state as possible.

Make small hotbeds for sowing Cucumbers and Melons, Radishes and Early Horn Carrots, Cauliflower and Walcheren Broccoli, Lettuce, and various other things, which will be found useful where the late severe weather, or other cause, may have diminished the autumn sowings.

THIRD WEEK.

GREENHOUSE AND CONSERVATORY.

Ventilation is requisite in mild weather, as stagnant air is always unfavourable, especially to the plants blooming in the conservatory. Water sparingly, and damp the house as moderately as possible, as water settling on the flowers will soon destroy them. When the plants, bulbs, or shrubs in the forcing-pit have developed their blossoms, let them be removed to the conservatory, where they can be preserved much longer in perfection. The plants to be looked over every morning, and every dead or decaying leaf and flower to be removed.

Heaths.—Fire heat should only be given when mats or other such coverings are not sufficient to exclude frost, as nothing so much injures the constitution of the Cape Heaths as a close, damp atmosphere. Air should be allowed to circulate freely amongst them at all opportunities.

Pelargoniums.—The plants intended for specimens should be finally shifted. Air to be admitted at all favourable opportunities, and a slight increase of temperature given. To be kept near the glass, and free from green fly. If they have made no winter growth they will now be the better prepared to progress in a robust, healthy state.

STOVE AND ORCHID-HOUSE.

Amaryllis.—Attend to the shifting of them as soon as they show signs of growth. Let them be placed in the stove, and give a little water, increasing it gradually as the leaves unfold.

Orchids.—If other departments of gardening are likely to occupy more time than can be very well spared as spring operations accumulate very fast, it is advisable to proceed with the potting of Orchids from this time forward, beginning with those that are showing signs of growth. Peat cut into from one to two-inch cubes, fresh sphagnum to be soaked in boiling water, to destroy insects, and charcoal lumps, with an abundance of crocks,

are the materials to be used. Any plants that had become very dry should be immersed in tepid water for an hour the day previous to shifting. The climate of the countries and the localities from whence the species come are the best guides to their successful cultivation; as the treatment required for Oncidium Carthaginense would kill O. bifolium, and Cattleya Forbesii will thrive where C. Skinneri will die, and in like manner with many others.

FORCING-HOUSES.

Capsicum.—Sow seeds of the large sort in pans or pots, to be placed in heat. When the seedlings are an inch or two high pot them singly into small pots, and replace them in heat; to be afterwards shifted when necessary until the end of May, when they may be planted out on a south border.

Cherries.—Plenty of air, atmospheric moisture, and a very moderate temperature, are the requisites for them. If the buds are beginning to swell, 45° will be enough to maintain by fire heat, lowering the temperature down to 40° at night, with a moist atmosphere.

Cucumbers.—The plants in bearing to get a top dressing of fresh, rich soil. Keep a sharp look out for the destruction of insects. When the plants in the seed-bed have made one rough leaf pinch off the leading shoot above it, so as to cause the plants to throw out two shoots from the axil of the leaves. Cuttings put in and struck in the seed-bed will come into bearing quicker than seedling plants.

Peaches.—If the weather is very dull and unfavourable for giving air where the trees are in bloom, it is advisable to shake the trellis towards noon for dispersing the pollen.

Pines.—Proceed with the routine as advised in last Calendar.

Strawberries.—Keep them close to the glass, and remember that they are impatient of heat: let 45° be about the maximum, with a very free circulation of air. If they are plunged in a pit or dung-bed, let the bottom heat be about 70° maximum, with an atmospheric warmth of 55° to 60°. In such a situation they will want scarcely

any water until they begin to throw up their blossom-spikes.

Tomatoes.—Sow seed of the large. To be treated as advised for Capsicums.

Vines.—To be looked over carefully, and as soon as they are sufficiently forward to distinguish the embryo fruit all useless shoots to be removed—that is, all that do not show fruit, and are not required for wood next season. It may also be necessary to take off some of the shoots that show fruit where they are very thick. If two shoots grow from one joint one of them should be removed.

FOURTH WEEK.

GREENHOUSE AND CONSERVATORY.

The compost intended for the plants in these houses should be prepared and sweetened by several turnings; and a sufficient supply for immediate use should be stored in an open shed.

Calceolarias (Herbaceous).—To be potted into larger pots as they require them; compost equal parts of turfy loam, peat, and leaf mould, with a sprinkling of silver sand. To be kept in a moderately-moist atmospheric temperature of from 45° at night to 55° in the day. To be slightly syringed with tepid water on sunny days, and to be kept free from
