Frequently, as in many Dicotyledons, the primary root, the original root of the seedling, persists throughout the life of the plant, forming, as often in biennials, a thickened tap-root, as in carrot, or in perennials, a much-branched root system.
In the last week, sow hardy annuals in the borders, with biennials that flower the first season, as also perennials.
Transplant from the nursery to their final sites annuals sown in autumn, with biennials and herbaceous plants.
Biennials and perennials should be sown before the middle of the month.
Sow annuals for succession in the last week, also biennials and perennials in the nursery compartment, for planting out next year.
