SPINACHIA, SPINACH; a genus of the pentandra order, belonging to the dioecia class of plants. There are two species. The common species intended for winter use should be sown on an open spot of ground in the latter end of July; observing to do it if possible when the weather is rainy. When the young plants are come up, the weeds must be destroyed, and the plants left at about five inches asunder. The ground being kept clear of weeds, the spinach will be fit for use in October. The way of gathering it to advantage is only to take off the longest leaves, leaving those in the centre to grow bigger; and at this rate a bed of spinach will furnish the table for a whole winter, till the spinach sown in spring is become fit for use, which is common in April.
