144 HOT-HOUSE — OF REPOTTING, ETC. [March. 
MARCH. 
If this department has heen regularly attended to, the 
plants will be in a fresh healthy state. Where there is any 
sickly appearance, heat has been deficient, or insects of a de- 
structive character are preying upon the plants. Too much 
water at the root frequently causes the foliage to become 
yellow. Regular syringing must be continued in the morn- 
ing, and it is highly necessary that the water that is used 
should be of the same temperature as the house ; and at all 
times, whatever water is given to the roots, the same must 
be observed. For airing, see last month, observing, as the 
season advances, to increase the quantity. 
Continue to fumigate when any of the Green-fly appears 
(see January for directions), and where there are any of the 
plants infected with the white scaly insect, clean them as 
there directed. If overlooked for a few months, they will 
be increased tenfold. Very frequently, where there are only 
a few, they are neglected until the plant is overrun with them, 
and then it may be said it is impossible to dislodge them 
entirely. Clear off all decayed leaves from the plants which 
will have made fresh shoots, for the decayed leaves very 
much disfigure the whole collection. We would not have 
repeated this observation if it was not an essential point, and 
one which is so frequently neglected. 
OF REPOTTING PLANTS. 
Many of the young plants that are growing freely, and 
where they may be desired to grow to a large size, should be 
frequently repotted to encourage their growth. Gesneria, 
Gloxinia, and others previously mentioned, i^Bst have larger 
pots, as they require it. Flowering bulbs of A man// 7 is may 
be brought into the heat to make them bloom early; before 
they begin to grow, divest them of the old soil, and put 
them into fresh : this is particularly necessary, when the 
bulbs are already in large pots. By thus renewing the soil, 
the pots can be used much smaller : they require plenty of 
drainage in the pot, and agree best with soil No. 12.
