The essential requirements of a soil upon which to grow onions profitably are a high state of fertility, good mechanical condition, properties – that is, if it contains sufficient sand and humus to be easily worked, is retentive of moisture and fertilizers, and is capable of drainage – all other requirements can be met.
Any watermelon grower can grow their own seed with very little trouble, as a small number of choice melons will furnish enough seed for planting his crop; in fact, four or five average melons will yield a pound of seed. The proper method of selecting the seed melons is to go through the field prior to the first picking and mark a number of melons having the desired type, color, and general characteristics. In making the selection, vigor and freedom of the vine from disease should be taken into consideration. One of the best methods of marking them is to tie pieces of white cloth to the stems of the melons. The marked melons should be allowed to remain on the vines until fully ripe, then carried to a safe place, and after 2 or 3 days of additional ripening should be opened and the seed separated from the pulp.
