A 3-inch potful of superphosphate should be mixed in to each bushel of soil. Keep them in a light, airy atmosphere and about a week after potting, pinch the tip of each plant to encourage branching. When the roots have enveloped the ball of potting soil, they are ready to be moved to their flowering stations. In a small greenhouse, or when a variety isn't offered commercially, young plants can be started at any time from cuttings taken from side growths. These root easily in sand.
Seedlings are usually more robust and are less likely to suffer from diseases, though.
These Antirrhinums are ideal for growing as rock garden plants. Return to the HOME PAGE .
