The difference between 'sowing' and 'planting'
- Sowing involves putting seeds into a soil, the seed then (hopefully) germinates and a plant grows - until the seed goes into the soil, the seed is dormant and needs no special attention (usually 'fresh' seeds have a shelf life of 2 to 4 years).
- Planting involves taking a living plant which needs water and light, and putting it into the soil. Plants can either be grown by a gardener from seed, or purchased from a nursery.
Explanations of terms used above:
'cloches' - a small, easily moveable 'mini-greenhouse' used to protect plants from the weather and to warm the soil.
'sowing under glass' - normally means within a heated greenhouse, (alternatively, small quantities can be sown indoors) normally the young plants will be planted out later. By sowing under glass, the plants get a 'heads-start' resulting in earlier crops after they have been planted out.
'seed bed' - a specific area of the garden where seeds are sown for germination and later 'planting out' to another area. The area is normally level and with a fine soil, this helps the young plants to grow and makes it easy to lift the plants for planting out.
'planting out' - applies where seeds have been sown and germinated in one place, and when the plants of an adequate size, the plants are moved to another area where the plants can mature.
