The soil must have adequate drainage; otherwise, air may be excluded, and the more beneficial micro-organisms may be destroyed. Soils which have poor drainage are often sour and acid. It will be necessary to improve this acidity by applications of hydrated lime. Wet soils are cold ones, and this means that plant growth is severely retarded. The situation is even […]
Shallots Some people prefer the milder flavor of shallot, Allium ascalonicum, which they grow in place of onions. However, shallots are grown for pickling. When stocks of non-bolting onion sets were not available, many gardeners found shallot growing far easier than onion growing. The soil in which they are to be grown must be well-drained and, unless very large bulbs […]

The slender woody stems are furnished with small, ovate to elliptic-lanceolate, green leaves and sharp thorns. The small inconspicuous flowers which are produced in summer, are surrounded by large colored bracts which form the […]
DRAINAGE One of the greatest drawbacks to successful gardening is badly drained ground. Wherever water lies in the ground at a depth easily reached by the roots of most cultivated plants they do not thrive, except where the water is constantly on the move, such as the bank of a river, brook or lake; there many plants will flourish.

Prick off into deep seed boxes as soon as the seedlings are large enough to handle, at 5cm (2in) intervals. After hardening off, plant out from mid May to the end of June, in prepared […]
Seed Seeds are produced by plants following the fertilization of the flower, as a means of reproducing the plant. Each seed is a plant embryo, which consists of a minute shoot and root and a store of food. The food reserve enables the embryo to grow before its root is developed to absorb nutrients from the soil and before the […]
