Tomatoes may be kept in storage much longer than is usually supposed. Fruits that have obtained nearly their full size will ripen up gradually if packed away in a cool, rather dark place. Placed in front of a window in the hot sun, as they sometimes are, they merely cook. All fruit to be kept should be very carefully picked and preferably wrapped individually in fruit papers such as those which come around fancy apples, or in pieces of newspaper. Any light piece of paper will do, or they may be packed away in crates in perfectly dry dead leaves or grass. It is also possible to keep the fruits for some time by taking up the best plants by the roots, trimming off the surplus foliage and hanging the skeleton plant, with the best fruit, up in a dark dry place. The tomatoes will continue to ripen gradually for some time.
