In the open ground Narcissus should be planted in quantity, especially in spots where it appears to be naturally at home, and one of the most charming effects is obtained by putting them in the rough grass adjoining shrubbery borders. Instead of cutting the grass, it must be allowed to throw up flower-heads, and this affords the bulbs time to mature in readiness for the following season. The many forms of Double and Single Daffodil are effective border flowers, and the numerous varieties of Narcissus should be grown in clumps and patches in every spot which is suitable and vacant. In the reserve border of many gardens large numbers of Pheasant’s Eye and other Narcissus are planted to supply flowers for cutting. They are peculiarly valuable for the purpose, and if cut when scarcely ready they will develop in water, and last for many days. In planting, be guided as to distance by the size of the bulb, allowing four or five inches between small sorts, and six to nine inches for large varieties; depth, six to nine inches.
Oxalis.—Except in a few sheltered districts, it will be necessary to cultivate this exceedingly pretty flower in frames, or in a sunny, airy greenhouse. It may also be forced in the stove with success. Put several bulbs in a pot, and give them a light soil with plenty of sand in it.
Snowdrop.—It does not improve the roots of this exquisite little favourite to keep them out of the ground, and they should, if possible, be planted early.
Sparaxis needs the same treatment as advised for the Ixia.
Sweet Pea.—Exhibitors of Sweet Peas and those who endeavour to secure the finest sprays for decorative purposes, commence the preparation of the ground during the present month and incur whatever expense may be necessary to insure a deep bed of rich friable loam in which the roots can ramify freely. It is also the practice to sow seeds about the middle of September in order to provide sturdy well-rooted plants in readiness for transfer to the prepared plots in early spring. Either pots or boxes may be used, and a frame is sufficient to bring the seedlings safely through the winter. The method is dealt with in detail on page 305.
From mid-September to the end of October, according to the locality, is an excellent time for sowing Sweet Peas outdoors where the soil is light and the situation fairly warm. Plants from autumn-sown seed are generally more robust and produce finer flowers than those raised from seed sown in the open in spring.
Tropæolum tuberosum.—In potting the tuberous varieties, insure efficient drainage, and use a compost of rich light loam mixed with sand. The foliage will trail over the sides of wire baskets with graceful effect, but it may be trained around balloon-shaped wires specially made for these flowers. The bulbs remain dormant all through the winter, and may be started at any time from September to March.
Tulip.—The early class of Tulips is of great value for forcing because of their brilliant colours and elegant forms. They take kindly to a high temperature, but forcing should not be commenced too early, nor should the heat be allowed to exceed 65° at the finish. Plunging is the most satisfactory method. Several bulbs may be put into one pot, but it is more convenient to grow them singly, so that flowers in exactly the same stage of development may be selected for use at one time. A continuous supply may be secured by potting batches at short intervals. When in bloom the roots can be washed free from soil for placing in vases. Decayed turf, with decomposed cow-manure and a proportion of sand, make an excellent potting soil for Tulips, and it will be all the more suitable if laid up in a heap for twelve months after being mixed.
OCTOBER
Anemone.—The tuberous-rooted Anemones may be planted in the open at any time from September to March, and from successive plantings a continuous display will be obtained from February until far into spring. For the choice named varieties it is customary for specialists to make elaborate preparations, into which we need not enter here. Splendid flowers can be grown in clumps and beds in ordinary gardens by deep digging, and the employment of a liberal dressing of decayed cow-manure. Plant the roots from four to six inches apart, and at a uniform depth of about three inches. In a heavy, retentive soil it is not advisable to risk a collection of named Anemones until January, unless a deep layer of light compost can be placed in the drills where the roots are to be planted.
