==Balsam==.—­Towards the middle of the month a final sowing may be made with safety in the open ground.  Former seedlings will need potting on until they reach the eight-inch size, and at each transfer put the plants in rather deeper than before; this encourages the growth of roots from the stems.  While increasing the pot-room not a bud will show; but immediately the roots are checked by the pots, flowering will commence.  The old method of stopping and disbudding not only spoiled the plants, but robbed them of the finest flowers, which are invariably produced on the main stem.  Since the natural method of growing Balsams has been in favour it is usual to see grand specimens covered with immense flowers.

==Campanula==.—­The hardy perennial varieties may be sown in the open during the present month to provide seedlings for transplanting to flowering positions in autumn.  Should there be any good reason for delay it will not be too late to sow in June or July, but the finest specimens are generally produced from May sowings.  The best results can always be obtained by raising the required number annually and discarding the plants after they have flowered in the following season.

==Cineraria.==—­Those who care to have Cinerarias in bloom during November and December may do so from a sowing made at the beginning of April, but it is not usual to start so early.  Our own practice is to sow twice, during the present month and again in June, to insure a succession.  From this month’s sowings we look for our finest plants.  The Cineraria is easy to raise and to grow, but it will by no means take care of itself.  It has so many enemies that unusual vigilance is necessary to flower it to perfection.  It thrives in a compost of turfy loam, with a little leaf-mould added; but the soil should not be over-rich, or there will be much foliage and few flowers.  Still, as the plant is a rapid grower, it must not be starved, neither must it suffer for lack of water.  Pots or pans may be employed for the seed; and as the young plants grow freely, they may go straight to thumb pots without the usual intermediate stage of pricking off.

==Coleus== should be finally shifted into 48-sized pots.  If signs of decline become manifest, weak liquid manure water given occasionally will revive the plants and intensify their colours.  During the summer any ordinary greenhouse or conservatory will suit them, provided they are shaded from fierce sunshine.

==Cyclamen.==—­The strongest seedlings should now be ready for 60-sized pots.  Abundant but judicious ventilation, plenty of water, and freedom from aphis, are the conditions to be secured.

==Dahlia.==—­Make the ground on which this flower is to be planted thoroughly rich.  It is a rapid grower, and cannot attain to fine proportions on a poor soil.  If the plants are carefully prepared for the change by free exposure on genial days, and also during warm nights, they will scarcely feel the removal.  When first put out, dress the surrounding soil with soot to prevent injury by slugs, which show a decided partiality for newly planted Dahlias.  Give water freely when requisite, and in staking the plants take care that the ties do not cut the branches.  These ties will require attention occasionally during the summer and autumn.
