Get a second growth of Cabbage

When you cut a cabbage, make two nicks crosswise on the top of the stump, and within a month or six weeks it will sprout again and give you a crop of tender greens.

Early Cucumbers and Melons

For early melons or cucumbers many plant the seeds on inverted sods cut about four inches square. The sods are placed in a frame of any kind, and covered to the depth of half an inch with mellow, rich earth. The plants root firmly in these sods the same as they would in small flower pots, and may safely be transplanted as soon as the weather becomes settled and warm. For melons this is an excellent plan, since our seasons are scarcely long enough to ripen them before the cool nights of autumn, when the seeds are planted in the ground in the usual way.

Substitute for Bean Poles

A New England farmer says: "In my own gardening I have found a most satisfactory substitute for bean poles, which latter are not only expensive, but a source of trouble and care. I plant a sunflower seed by each hill of beans, the stock answering the same purpose as the ordinary bean pole, besides providing an excellent feed for my poultry. I have been using for this purpose a mammoth variety of sunflower seed, many of the flowers of which measured fifteen inches across the seed bed."

Making Pumpkins Grow Fast

A good way of hustling the growth of pumpkins, marrows*, etc., is to feed the fruits with water. It is only needful to secure some pieces of round lamp wick. Holes are made in the stalk of the fruit and, into these, one end of the wick is inserted. The other end of the wick rests in a jar of water which is kept well supplied. The pumpkins grow at twice the rate they do normally and are ready for cutting much sooner. In this way the produce secured from the plant is largely increased. The plan is well worth following out.–S. Leonard Bastin from: The Garden Magazine - June 1918

*squash - this would likely work with most melons and squash
