The Culture Of Vegetables And Flowers From Seeds And Roots Part 43

They do not transplant well, and therefore a showery day should, if possible, be selected for moving them. In the absence of rain, be liberal with water. They are very brittle, and should have a position somewhat sheltered from the full force of the wind; and as they revel in suns.h.i.+ne, the more roasting the season the finer will be the flowers.

==JULY==

==Antirrhinum.==--A sowing in drills during the present month or August will supply plants for flowering next year. Transfer direct from the seed-bed to the positions where they are intended to bloom.

==Calceolaria.==--If more plants are wanted, sow again. Among the seedlings which we left last month just as they had been p.r.i.c.ked off, it will soon be evident that there is a wide difference between the strength of the plants. As a rule, the most robust are those in which yellow largely predominates. These make bright and showy decorative plants, but the colours that are especially valued by florists will probably come from the seedlings which are weakly in the early stage.

Hence these should be specially prized, and under skilful management they may be grown into grand specimens. The thumb pots for Calceolarias need careful preparation with crocks covered with clean moss or vegetable fibre, and they must be filled with rich porous compost.

Transfer the plants with extreme care, and place them in a sheltered part of the greenhouse or in a shaded frame, allowing free access of air on the leeward side. If aphis has to be dealt with--and it is very partial to Calceolarias--fumigation is the best remedy. Choose a quiet evening for the operation; on the following day carefully water the plants and shade them from the sun.

==Campanula.==--The perennial varieties may still be sown, either in pans or in the open. Give them a good light soil, and do not stint the supply of water.

==Cyclamens== which are forward enough should be s.h.i.+fted into 48-sized pots. Follow up the process until all are re-potted.

==Lobelia.==--In pots or pans sow seed of the perennial varieties to provide plants for the borders next year. Pot off singly when ready, and protect in a cold frame through the winter.

==Mimulus== sown in the open ground will flower in the following spring.

If possible, make the seed-bed in a moist retentive soil and in a shaded situation.

==Primula.==--To force the growth of this plant is to ruin it. The most satisfactory results are invariably obtained from specimens which have matured slowly, and have been treated as nearly hardy after the seedling stage. From this month up to the middle of September it will be quite safe to expose them freely, day and night, except in inclement weather.

Even in the winter protection is only needed from frost, damp, and keen winds.

==AUGUST==

==Annuals and Biennials, Hardy.==--In the majority of English gardens the spring display of bulbous flowers is too often followed by a dreary blank, which is almost unredeemed by a touch of colour, except that afforded by the late Tulips and a few other flowers which are relatively unimportant. The brilliance of the Crocuses, Hyacinths, and early Tulips serves to throw into relief the comparative barrenness which follows.

And the contrast is rendered all the more striking by the cheerful spring days. It is at this juncture that annuals and biennials from summer or early autumn sowings light up the garden with welcome ma.s.ses and bands of fresh and vivid colouring. They are then so valuable that it is surprising they are not more commonly grown, especially as the cost of seed is very trifling. Even the transitory character of some of them is an element in their favour, for they do not interfere with the summer bedding arrangements. Such flowers as Pansy and Viola, however, produce a long-continued show of bloom.

The following list contains the varieties which are best adapted for the purpose:--

Alyssum, Sweet Antirrhinum Asperula azurea setosa Calandrinia umbellata Calendula officinalis fl. pl.

Candytuft Cheiranthus Allionii Chrysanthemum, Morning Star Chrysanthemum, Evening Star Chrysanthemum inodorum plenissimum Chrysanthemum segetum gr.

Clarkia Collinsia Coreopsis Cornflower Erysimum Eschscholtzia Gilia tricolor G.o.detia Iceland Poppy Larkspur, dwarf rocket Leptosiphon Limnanthes Douglasii Linaria, pink Nemophila Nigella, Miss Jekyll Papaver glauc.u.m Phacelia tanacetifolia Poppy, s.h.i.+rley Saponaria calabrica Scabious Silene Sweet Sultan Venus' Looking-gla.s.s, purple Virginian Stock Viscaria Whitlavia

Sow thinly, not later than the middle of the month in cold districts, but September will be early enough in the Southern counties. Drills are preferable to broadcasting, because the beds are more easily weeded and kept in order. Thin the rows early, so that the plants may become stout and hard before winter overtakes them. Early in the new year transplanting must be resorted to during open weather if the plants are to be flowered in heavy soil; but on light, rich land, sow where they are intended to bloom.

==Annuals under Gla.s.s.==--The flowers available for winter and spring blooming are naturally few in number compared with those which fill gardens and conservatories during the summer months. But it is not generally realised that several favourite outdoor annuals are as serviceable for flowering under gla.s.s in the short days of the year as they are for growing in the open ground in summer, and they are the more valuable for winter and spring use as no elaborate system of cultivation is needed. Any greenhouse or conservatory from which frost can be excluded will grow these annuals well. Seed should be sown in August or September, in pots or pans placed in a cool house or frame. When the seedlings have made some progress, p.r.i.c.k them off into the pots in which they are wanted to flower, and grow steadily on, bearing in mind always that the most important point is to keep the plants as hardy as possible by giving air at every favourable opportunity. The following varieties are especially suitable for winter and spring flowering under gla.s.s:--Alonsoa; The Star and Dunnettii varieties of Annual Chrysanthemum; Clarkia elegans; Dimorphotheca; Gypsophila elegans; Linaria; Nemesia Suttoni; Nicotiana, Miniature White and N. affinis; Phlox, Purity; Salpiglossis; and Swan River Daisy.

==Asters== for indoor decoration should now be lifted from beds or borders and potted. It is worth a little trouble to accomplish the task with the least possible injury or disturbance to the roots. Light soils should have a good soaking of water on the previous evening, to prevent the mould from crumbling away.

==Carnation.==--Seed may still be sown as advised in April; but to carry the plants safely through the winter it is necessary to have them strong before cold weather sets in.

==Chionodoxa== can be forced with the same ease as Roman Hyacinths. A 48-sized pot will accommodate several bulbs.

==Cinerarias== are frequently placed in the open during this month and September, and as it tends to impart a hardy const.i.tution, the practice is to be commended. A north border under a wall will suit them, but the proximity of a hedge should be avoided. Before the plants are put out see that they are quite clean, or it may be necessary to restore them to the house in order to rid them of some troublesome pest.

==Clarkia.==--The varieties of the Elegans cla.s.s make very handsome pot plants, and to insure the requisite number seed must be sown in well-drained pots during this month or early in September.

==Cyclamen.==--Where Cyclamens are extensively grown it is usual to make the first sowing in August, and many gardeners regard this as the most important period for securing healthy young seedlings. A common mistake with beginners is to raise them in too high a temperature. On this and other points useful suggestions will be found in the article commencing on page 256.

==Dianthus.==--Either now or a little later transfer seedlings to flowering quarters, and if possible put them into sandy loam in a sunny spot.

==Freesia.==--Few and simple are the conditions necessary to the well-being of this beautiful and delicately scented flower. The fine specimens to be seen occasionally in cottagers' windows in the Isle of Wight attest the ease with which it can be grown in a congenial atmosphere. The bulbs are exceedingly small in proportion to the flowers, and the rootlets are so fragile that potting on is to be avoided. A 48-sized pot will hold five or six bulbs, and the soil should consist largely of decaying vegetable fibre, such as peat, leaf-mould, and turfy loam. The pots can be stood in any sheltered position out of doors, under a covering of cocoa-nut fibre or other light material, until the foliage begins to grow.

==Geranium==.--A sowing in August will supply plants for flowering next summer, and the directions given in February are suitable, save that heat can now be dispensed with. These late seedlings will need more care to carry them through the winter than plants raised earlier in the year.

==Gerbera==.--These charming flowers make admirable subjects for the greenhouse and conservatory, and an excellent display may also be obtained outdoors if a sunny well-drained part of the garden be selected for the plants. August is the best month for sowing seed. Plants required for indoor blooming should be potted on as may become necessary. Those for the open ground must be thoroughly hardened off for planting out in the early summer of the succeeding year.

==Hyacinths, Italian and Roman==.--Obtain the bulbs as early as possible, and pot them promptly. Place them in any spare corner of the open ground, where they can be covered with cocoa-nut fibre or leaf-mould until the roots are formed. A child can grow these flowers; and they should be largely employed for bouquets and for indoor decoration during the dark winter days.

==Mignonette==.--For winter flowering sow in 48-or 32-sized pots, filled with light rich soil. Put the seed in little groups, thin to three or five plants in each pot, and give them the benefit of full daylight close to the gla.s.s. When flowering commences do not allow seed to form.

If the spikes which have pa.s.sed the heyday of perfection are cut off, the plants will break again and flower a second time.

==Narcissi==.--The first potting of early varieties is made this month as soon as the bulbs can be obtained.

==Pelargonium==.--The remarks under Geranium apply to this flower also.

==Picotee==.--Follow the instructions given for Carnation.

==Schizanthus==.--To do full justice to this flower seed should be sown now for plants to be kept through the winter in any house which is sufficiently warm to exclude frost.

==Scilla praec.o.x, or sibirica==.--The treatment which suits Roman Hyacinths will answer for this bulb also, when required for flowering indoors. The two form an admirable harmony in blue and white.

==Silene==.--All the most useful varieties of Catchfly are hardy against cold, but not entirely so against damp. They possess a special value for their sparkling appearance in spring. Sow in light sandy soil, in which they will pa.s.s the winter safely. On a heavy loam the transplanting system must be resorted to in February or March.

==Stock, Intermediate==.--This section is valuable for indoor decoration in spring. No artificial heat is necessary to raise the seed; in fact, it is not wise to employ it. Either in this month or early in September sow the required number of pots and plunge them in ashes in a frame until March. Thin the seedlings to three in each pot. Before flowering, a rich top-dressing will be beneficial; and manure water--weak at first, but stronger by degrees--will intensify the colours.

==Stock, Spring-flowering.==--A bed prepared under trees or shrubs will afford some shelter from winter frost. Make it thoroughly rich, and in it plant the seedlings. Should the growth be very rapid in September, the plants will probably become too succulent to endure the stress of winter. If so, lift them and plant again on the same spot.

==Sweet Pea==.--The modern culture of this delightful flower includes deep trenching and the liberal use of manure. Those who intend to sow during September in the open must get the trenched ground into perfect order early in the present month. The details are important and are fully described in the article commencing on page 303.

==SEPTEMBER==

==Agapanthus== taxes the soil severely, and must have ample nourishment in pots. It is also one of the thirstiest bulbs known, but is quite hardy, and will thrive in the open if planted in a deep rich loam at any time from September until March.

==Alstroemeria==.--Although related to the Ixia, this bulb may be trusted to the open ground in all but the coldest districts of the country. It is not suitable for pot culture, but in a dry border it may be allowed to remain undisturbed for years. Plant quite nine inches deep.

==Amaryllis==.--The proper time to commence operations with these superb flowers is during their season of rest, which ranges from September to March. Pot them in firm loam, enriched with leaf-mould, and containing a fair proportion of sand. Very little water is required until growth begins, and then it must be increased with the progress of the plant.

Start them by plunging the pots in a temperature of about 65, and when they are coming into bloom, remove to a warm greenhouse or conservatory.

After the flowers have faded, allow the plants to complete their growth, and then slowly reduce them to a resting condition without permitting the bulbs at any time to become quite dry.

==Anemone==.--The tuberous varieties are valuable as pot plants, not only for their flowers, but also for the distinctive character of the foliage. The roots may be potted from now up to the end of the year, so that a succession of flowers can be easily insured. When plunged in a pit or frame to preserve them from frost, watering is all the attention they will need, but of this there must be plenty, particularly when the plants begin to flower. Pot the roots between one and two inches deep, in rich soil, and with the eyes upwards. A large pot will accommodate several roots.

==Babiana==.--Treat in the same manner as the Ixia.

==Begonia, Tuberous-rooted.==--Lift the plants which are in the open ground, and pot them to complete their season in the greenhouse; but if they are not wanted for this purpose, they may remain in the beds until October. When the stems fall, still retain the bulbs in their own pots, and store them in a dry cellar or shed, under a layer of cocoa-nut fibre. They need protection from both damp and cold. Neither hurry the drying off of the roots, nor attempt to force the growth in spring, but wait until they start naturally.

==Calceolarias== ought now to be in large 60-pots, placed close to the gla.s.s to insure a dwarf habit. During sharp weather they may be taken down, but should be restored immediately the danger is past. Much heat in winter will be injurious; a range of 45 to 55 should be considered the limits of variation in temperature. Pot the plants on as growth demands.
