Florida Cooperative Extension One or two trees of superior quality are to be found in nearly every guava grove in Florida. The guava succeeds in nearly every type soil, thriving in light sandy soils or on the heavier land. While it will produce satis- factory crops under poor conditions, the guava responds most generously to cultivation and fertilization. Barnyard manure may be used or a complete chemical fertilizer will stimulate growth and aid greatly in the production of large, fine fruit. The use of the guava in the diet may be justified on the score of its hygienic and medicinal virtues. The analysis shows the mineral content as being a little higher than for most fruits. The guava contains more than the average amount of potassium, which contributes to its potential alkalinity. The guava is rich in vitamin C, said to be an important factor in preventing tooth decay and of much of the so-called rheumatism in children and adults. The guava may be either eaten out of the hand, sliced with cream, served in shortcake and pie, or made into jelly, jam, or preserves. It is pre-eminently a fruit for jelly-making and other preserving purposes. Indeed, guava jelly is conceded to be the "facile princeps" of its kind. It is interesting to note that the acid and pectin are so concentrated that three times the weight in sugar may be added to the juice. It is estimated that 100 pounds of fresh, acid guavas will yield 350 pounds of jelly. More- over, acid guavas are often extracted three or four times and the fourth extraction even will yield an acceptable quality of jelly. In the vernacular of a present-day enthusiast, we have this recommendation for the use of the guava in the fresh state: "Pick out some nice, large guavas and peel them carefully. Scoop out the seed mass and run it through the fruit press. Slice the guava into spoonful chunks and mix with the fruit from which the seed has been extracted, add a little sugar and a little lemon or lime juice. Put in the ice-box until ready to serve, and then serve with good, rich fresh cream. Oh boy! a peach in its prime is no better." PRESERVATION OF THE GUAVA Guavas may be canned, preserved, spiced or made into butter and paste, relishes, catsups and chutneys. The juice may be used for punch and jelly stock. These are some of the products that should be made by the provident Florida housewife.
