==Lobelia==.—­Early in the month transfer the seedlings to pans or boxes, but the latter are preferable.  Not a single flower should be allowed to show until the plants are established in the open ground.  Although Lobelias are very attractive in pots, they cannot be satisfactorily grown in them, with the exception of the =ramosa= varieties.  But the object is easily attained by potting plants from a reserve bed after they have developed into good tufts.  From a stiff soil they can be lifted and potted with facility; and a light soil will cause no difficulty if the bed be soaked a short time in advance.  After potting, the plants will give no trouble, except to supply them with water.

==Marigolds== can be raised in a cold frame, and towards the end of the month there will be no risk in sowing in the open ground.  The plants thrive in a sunny position, even in scorching seasons.

==Marvel of Peru==.—­If not sown last month, there is no time to lose; and with a little care seed can now be germinated without artificial heat.  When the plants come to be transferred to the open, put them, if possible, in sandy loam, exposed to full sunshine.

==Mignonette==.—­Successional sowings may be made up to the end of June.  Give each plant plenty of room.  By removing the seed-pods as fast as they are formed flowering is greatly prolonged.

==Nasturtium==.—­Both dwarf and tall varieties are usually treated as hardy annuals, with the exception of the date of sowing.  None of the Nasturtiums are quite hardy, and if sown in March the plants are liable to destruction by late frosts.  It is therefore usual to sow in April or May, according to the district, and the growth is so rapid that the plants are full of bloom before the summer has far advanced.  Sow on poor soil always.

The =Tropaeolum canariense= (Canary Creeper) may be raised in pans from a March sowing for planting out in May, or seed can be sown in the open during April.

==Petunia==.—–­ Plants from the first sowing will be ready for small pots, and they must be kept going until the 48-or 32-size is reached.  All Petunias rebel if root-bound, and the double varieties are especially impatient in this respect.  After each transfer give them a sheltered, shady position and attention with water until they start again.  Good drainage and careful ventilation are essential, or the foliage will lose colour.  Seedlings intended for beds may be transferred direct from the seed-pans into 60-sized pots.

==Picotee and Pink==.—­See the culture prescribed for Carnation.

==Ricinus==.—­At quite the end of the month or the beginning of May, seed put into the open ground will produce splendid specimens if treated with a lavish hand.  Take out the soil for a depth of eighteen inches or two feet, and fill the space to within three inches of the surface with a mixture of rich soil and well-decayed manure.  Upon each bed thus made place three Ricinus beans in a triangle,
