CALENDAR FOR MARCH. 
For the destruction of these pests the best application for the 
common species of green-fly, is to fumigate the houses or pits 
infested with tobacco, filling the place densely full of smoke as 
often as the appearance of the insect renders the application ne¬ 
cessary. This will in general destroy the thrip also. To the red 
spider a moist atmosphere is very inimical, and, in conjunction 
with occasionally washing the flues or heating pipes with white¬ 
wash and sulphur mixed in it, they may be kept under. If, 
however, they are very numerous on the plants the leaves should 
be well dusted over with flour of sulphur ; but the necessity for 
this ought not to arise. 
In the flower garden attention should be paid to protecting 
beds of bulbs from hail, or too much wet, by coverings of mats 
or other materials at night, and also during the day, if necessary. 
The seeds of hardy annuals should also be sown where they are 
intended to remain. The lawns and walks should also receive 
great care, as on their management now depends much of their 
neatness and beauty for the rest of the season. 
The greenhouse plants should he carefully attended to in wa¬ 
tering, staking out, and making the greatest display of those ad¬ 
vancing into flower. All air should be given that can well be 
admitted, without exposing the plants to cold and drying winds. 
Uepot all plants advancing ingrowth, as heaths, &c., taking espe¬ 
cial care that the drainage in all cases is perfect. Begin to for¬ 
ward the plants intended for bedding out in the flower garden, 
whether in houses or pits, and continue to propagate to the ne¬ 
cessary extent. 
Similar directions may be applied to the plant stoves, taking 
care to gradually increase the heat as the days lengthen, and 
also the supply of moisture. Continue to shift any plants 
whose growth may render such a step requisite, and be careful 
that the supply of water is not too great for the state of the 
roots. Foreign seeds should also be sown early in the month, 
and imported Orchidacese, bulbs, or other plants, should also be 
induced to commence their growth.
