Answer: Janey,
The best way to rejuvenate any type of old fruit trees is through pruning, increasing soil fertility and controlling diseases and insect damage.
Pruning: First remove any broken and dead or diseased branches and then prune the tree to the proper shape and size. Remove any suckers and crossing branches to create an overall shape that radiates out from the center. This will allow plenty of sunlight and air circulation into the canopy. Pruning should be done in the late winter or early spring. Because no more of 25% to 30% of the total canopy should be removed in one season, if you haven't been pruning regularly, you may need to shape the tree over a period of 2 to 3 years before resuming a lighter annual pruning schedule.
Soil Fertility: Aerating and amending the soil around your tree with organic nutrients is the best way to increase your soil's fertility. Spring is a good time to apply a high-nitrogen fertilizer as well as removing any competing grass and weeds from underneath the tree.
Disease & Insects: Inspect your tree for insect and disease problems. There are several good books and Internet resources dedicated to the identification and control of fruit tree pests and diseases.
Good Luck!
