==Gaillardia.==—­To secure a supply of plants for the open ground in May, seed of all the varieties may be sown during this month.  Prick off early and keep them dwarf.

==Geum.==—­From seed sown this month or in April, the popular double variety, Mrs. Bradshaw, may be brought into flower in the first year.  The seedlings should be pricked off into boxes and gradually hardened for putting out in May or June.

==Gladiolus==.—­This is one of the most stately and beautiful flowers grown in our gardens.  Some of the varieties are strikingly brilliant; others are exceedingly delicate in tint and refined in their markings.  The culture may be of the most primitive kind, or it may become one of the fine arts of horticulture.  Simply put into the ground and left to fight their own battle, the corms sometimes produce splendid spikes of flower, although not so imposing as better culture might have made them.  Under skilful care the flowers are magnificent in size and colour.

The main work of preparing the ground should be done in autumn.  Now it is only necessary to give the soil two or three light forkings, and those not deep enough to bring the buried manure to the surface.  This frequent stirring is beneficial in itself, and it promotes the destruction of the foes which prey upon Gladiolus roots.  Small Potatoes, roughly hollowed out, or pieces of Carrot, may be used as traps for wireworm and other vermin.  Planting is sometimes done at the end of this month, but as a rule it is better to wait until the beginning of April.

==Gloxinia==.—­There is yet time to secure a brilliant summer display from seed.  Bulbs which have been stored through the winter need attention.  Where these flowers are wanted early, and there is plenty of room, a commencement will probably be made in February; but in the greater number of gardens March is soon enough.  Assuming the bulbs to be sound, they should be potted in a mixture of loam, peat, and sand.  Those which start first must be re-potted for a forward supply.  While growing, manure water twice a week will help to produce fine flowers, intense in colour; but when the flowers open, the liquid manure must be abandoned, and pure soft water be given as often as necessary, for Gloxinias cannot endure drought.  Shading is an important matter from the commencement, and particularly during the flowering period.

==Hollyhock== seedlings will be ready for putting into thumb pots.  Directly they are established, begin to prepare them for planting out in May.

==Impatiens==.—­Some growers find a little difficulty in raising this elegant flower from seed.  Probably it arises from sowing too early.  Where there is a command of sufficient heat no trouble should be experienced in March, and it is essential to sow very thinly for two reasons.  Crowded seedlings are liable to damp off, particularly in dull, moist weather, and they are so fragile that it is well-nigh impossible to transfer them from the seed-pots until they are about an inch high.
