I think there are few localities better adapted to celery culture than that around Detroit city. The soil is well suited, being heavy and of a dark sandy nature. Of course celery will do very well in other soils, such as a light sandy one or clay, if manured heavily. And, indeed, celery gives good returns for manure, no matter what the soil may be. Cow and hog manure are best; fertilizers are of little use except on low lands. I have raised the best of crops on new ground of a dark, heavy nature without manure. The time for sowing seeds with us is, one lot the first week in April, the other the third week in the month. The seeds are sown in rows, in beds, and well patted down with the spade afterwards. This makes the earth firm around the seeds and is worth a dozen waterings. Planting is commenced about the middle of June and continued until the middle of July. The first planted we commence to earth up the end of August. This is done three times; the final banking up being about the middle of September. Celery bleaches best when boards are used, but the boards stop the growth by confining the plants too much; hence such plants are not as large or as heavy as earth bleached ones are.
For winter use we dig trenches a foot wide, standing the plants close together and putting earth on the roots only. A foot board covers the top and horse manure is put on it little by little as the cold increases.
