- Tree Fruit
Apricots are the first fruit trees to bloom in the spring and because of this they are susceptible to spring frost damage. Plant apricot trees in spots where spring frosts are rare. Apricots can be grown where peaches will grow. Apricot trees are reasonably winter hardy, but not so hardy as apples. Plant in well-drained soils. Apricots do not like "wet feet."

|GOLDSTRIKE||Requires cross pollination. A new variety from Washington State. Large sized fruit, orange with some red blush, firm.|
|HARGRAND||A large, juicy, good flavored variety developed in Ontario. Also Harglow, Harlayne, and Harogem.|
|PERFECTION||Needs cross pollination. Very large fruit. Orange skin and flesh. Good quality and flavor. Ripens last week of July. Very frost tender.|
|PUI-SHA-SIN||Chinese variety introduced by the Summerland Research Station. Very large fruit. Early blooming and early maturing. Excellent flavor. Fruit has tender skin.|
|RELIABLE||Requires cross pollination. Medium sized fruit. Good for fresh eating and processing. Has been grown locally for several years. Moderately frost hardy.|
|RIVAL||Requires cross pollination. Fruit is yellow with rosy cheeks. Large sized, orange flesh. Tree is winter hardy, blooms early. Developed by Washington State University.|
|SKAHA||Developed at the Summerland Research Station. Large, firm, bright orange when mature. Fruit has red blush, attractive. Ripens in the third week of July. Moderately frost tender.|
|SUNDROP||Requires cross pollination. Developed at the Summerland Research Station. Don't pick too early or flavor will be flat. Fruit, medium sized, bright orange, attractive. Ripens in the third week of July. Moderately frost hardy.|
|TILTON||Small to medium sized fruit. Yellow skin with red blush, good flavor, excellent for canning and drying. Ripens mid-August. Moderately frost tender.|
|TOMCAT||Partially self fruitful. Fruit ripens 3-4 days earlier than Goldstrike. Fruit is creamy yellow with no blush. It's more flavorful than Goldstrike or Goldbar, but fruit is smaller. Tree is not winter hardy, but is productive.|

Apricot trees grow to become relatively large. An area with a minimum diameter of 25 ft. (7.6 meters) should be allowed. Select a well grown one or two year old tree from the nursery. Two year old trees should have at least four of five well-spaced branches, with a good root system. The usual practice is to plant early in the spring, but planting can be completed in the fall when weather conditions are good and the soil is moist.
Prepare a hole slightly larger than the root spread. Trim off any broken roots before planting. If the tree is in a plastic pot, remove the pot. If it comes in a fiber pot, you can slit the sides and plant with the pot or remove the pot. Sprinkle a handful of bone meal (phosphorus) in the bottom of the hole to help the root system get established. Place the tree in the hole. Mix in some peat moss or compost with the planting soil. Replace the soil in the hole, treading the soil firmly around the roots to ensure that the tree is securely anchored in the ground. Give the tree a good watering. An area of about 4 ft. in diameter (1.2 meters) should be kept free of weeds or lawn grass during the early stages of growth. Organic or plastic mulches can also be used to suppress weed growth around the tree.
At planting time cut a one year old tree back to a height of 33 to 36 inches (82.5-90 cm). If a two year old tree is planted, reduce the branches to four well spaced shoots and shorten each one by one third. Apricots are usually grown as open center trees with the central leader removed. Aim to develop a framework of well-spaced branches that are capable or bearing heavy crops without breaking. In subsequent years build up the framework branches and cut out the entire shoots that are crowded or crossing into the center of the tree. Narrow angled crotches should be avoided as these are sources of weakness. Because apricot trees can grow to be large, in later years it may be necessary to cut or head back limbs in order to encourage more growth in the lower parts of the tree. Always cut back to a lateral or side growing branch.
Soils in the Southern Interior are chronically low in organic matter and nitrogen. Minor elements such as magnesium, boron, and zinc may be low as well. If good weed control is practiced, no fertilizer should be required for the first two or three years. When the tree starts to crop, apply one ounce (28 grams) of a complete fertilizer such as 12-16-12 (which contains minor elements) per square yard (0.8 sq. meters) in the fall. In mature trees the aim is to get 15 inches (38 cm) of new growth every year. Nutrients can also be applied as foliar sprays in early summer. Organic growers should use approved sources of organic nutrients.
If the tree sets a heavy crop and no thinning is done, the fruit will be small at harvest time. Thus, removal of part of the crop is necessary. To do this, space the fruits about 1 - 2 inches (3.8 - 5 cm) apart. Early thinning results in more uniform ripening. Fruit on well-thinned trees will ripen several days earlier than on poorly or unthinned trees. There will still be mixed maturities, even on well thinned trees, so more than one pick may be necessary. Heat greatly accelerates maturity.
Apricots must mature on the tree but they can ripen either on or off the tree. If left until they are good to eat, they will bruise very easily with picking and transport. Background color is used as a guide for harvest maturity.
Insects that attack apricot trees are: aphids, earwigs, fruit tree leafrollers, and peach tree borer. Diseases include brown rot and coryneum blight. Home gardeners often apply a dormant spray of oil. DO NOT apply lime-sulfur on apricots. It will burn the fruit buds and shoots. For more information on pest control check "A Guide to Fruit Tree Sprays for the Home Garden " published by the B.C. Ministry of Agriculture and Lands or consult the BCMAL publication "BC Home and Garden Pest Management Guide". Organic gardeners should use accepted organic methods of pest control.
