VASES AND TUBS FOR THE GARDEN
Vases and tubs provide the gardener with a means of maintaining a succession of colour in the garden by using them, as it were, in relays. When the bulbs and wallflowers are over, the tubs containing them are brought in and replaced by others containing geraniums or agapanthus. Formal trees such as standard bay or mop-head acacias may also be grown in tubs on a paved terrace and be very effective.
Stone vases are suitable in positions suited to stone seats, and any kind of tub or vase is best used in a formal part of the garden. They are especially valuable upon roof gardens and terraces, or upon either side of a formal seat.
Metal linings may be obtained for wooden tubs to preserve the wood, but these are not necessary in teak or oak ones although they save the staining of the wood where theand water percolate through the joints. All tubs should have drainage holes bored in the bottom.
Tubs may easily be made at home, while some of the most effective are made from empty wine casks cut in half, and painted green with black bands. These are most suitable for growing agapanthus and other plants which need plenty of room and they allow colour to be massed.
