But before you complete this step you must be sure that the weather conditions are suitable. The time to transplant cool-season crops such as lettuce and celery is when the outside temperature averages 55 to 75° F. For warm-season crops such as tomatoes and peppers, the time to transplant is when the average outside temperature is in the 65 to 80° F range. (For a breakdown of cool- and warm-season crops see Figure 6.02.]
Seeds can also be sown directly into small pots or cubes made of biodegradable material. Generally it's one seed to a pot After the plants have come up, and when the temperature is right for the particular vegetable (see above), you can plant each of these containers directly into the garden bed or larger container. Roots grow right through the wall of the pots and spread into the surrounding soil.
One of the major advantages of this procedure is that it avoids the root shock that besets many vegetables when they are transplanted. Large-seeded plants such as squash and melons should always be handled in this way; their root systems do not tolerate transplanting well.
