<h3 class="s3">APRICOT</h3> <p class="s4">Rosaceae Prunus armeniaca</p> <h4>Apricot performance in low chill locations</h4> <hr align="left" width="514" /> <img src="https://www.crfg.org/pubs/ff/apricot.jpg" width="378" height="296" align="right" /> Common Names: <span class="p">Apricot, damasco, albaricoque</span> <b>Related Species: </b>Plum (such as European plum, <i>Prunus domestica</i>, or the Japanese plum, <i>Prunus salicina</i>), Peach (<i>Prunus persica</i>), Cherry (such as wild cherry, <i>Prunus avium</i>, sour cherry, <i>Prunus cerasus</i>), Almond (<i>Prunus dulcis</i>), or the Capulin (<i>prunus salicifolia</i>). Distant affinity: <span class="p">Rose family fruit, apples, pears, quince, strawberry, blackberry.</span> Origin: <span class="p">Eastern Asia, Armenia, Northern China</span> Adaptation: <span class="p">Sites with cool or cold winters and warm summers. Spring frost can damage buds and blossoms. High heat (deserts) can damage fruit.</span> <p class="s6">DESCRIPTION</p> Growth Habit<span class="p">: Deciduous trees 15 to 25 feet tall and wide. Dwarfing root stock available. Planting near vegetable garden increases disease risk (verticillium).</span> Foliage<span class="p">: Green ovate leaves, lightly serrated 2-4 inches long on 1½</span> inch petioles. Flowers<span class="p">: Single white or pink rose type flowers, mostly on spurs. Some cultivars need a pollinator.</span> Fruit<span class="p">: Ping pong ball to slightly larger than a golf ball size fruit, red, orange or yellow in color. Single hard seed is smooth and free or semi-free. Fruit has midline indentation. In heavy crop years fruit should be thinned (2 inch separation).</span> <p class="s6">CULTURE</p> Location<span class="p">: Plant in low ground or where cold air collects.</span> Frost Protection<span class="p">: Apricots need winter chill but spring frost can damage buds and flowers.</span> Sun Protection: <span class="p">From the ground up 15 inches (+/-), wrap young tree trunks with foil, newspaper, or apply white wash. This will protect from sunburn until bark matures.</span> Soil<span class="p">: Deep loam or clay loam but fairly adaptable.</span> Irrigation<span class="p">: Deep water regularly in spring, summer and fall. Cover much of the ground under the canopy. Do not put water on the trunk. Allow the soil surface to dry between irrigations. Mulching will help conserve moisture but keep the mulch away from the trunk.</span> Fertilization<span class="p">: The preferable fertilization schedule is small amounts of fertilizer several times a year. The first application should be applied in late winter (February or March). Use a light application of NPK 8-8-8 (or ½ recommended 15-15-15). After fruit harvest, apply a stronger nitrogen such as 5-1-1, and in late summer a light dressing of a higher phosphorous (5-10-5) to promote spring blossom. Keep nitrogen low to avoid forcing new growth. The potassium is adequate with this schedule. This fertilization schedule provides good nutrition. Trees will produce somewhat less with less nutrition. Too little fertilizer is better than too much.</span> Pruning<span class="p">: Prune young trees when dormant to develop 3 or 4 scaffold limbs. Fruiting spurs need light so keep center of tree open. Leave enough new wood to protect fruit from sunburn.</span> Pests and diseases<span class="p">: Brown rot, shot hole and Eutypa dieback, occasional codling moth attack. Do not spray apricot trees with lime sulphur.</span> Propagation<span class="p">: Varieties may be grafted on peach, apricot or myrobalan plum rootstocks. Seedling apricots are slow to produce fruit and quality is unpredictable.</span> Harvest<span class="p">: Please see notes in “Cultivars” section below.</span> Commercial Potential<span class="p">: This fruit is currently a commercial crop in areas of adequate chill hours.</span> <p class="s6">CULTIVARS</p> Listed in approximate order of maturity. Time of maturity varies year to year. Most data collected from San Diego County, i.e., performance data for low chill areas (400 hrs. or less below 45<span class="s7">◦</span>F). <table border="1" width="100%" cellspacing="1" cellpadding="1"> <tbody> <tr> <td width="18%"> <p class="s8">Cultivar Name</p> </td> <td width="12%"> <p class="s8">Ripens</p> </td> <td width="70%"> <p class="s8" align="center">Notes</p> </td> </tr> <tr> <td> <p class="s9">EarliGold*</p> </td> <td> <p class="s9">4<span class="s10">th </span>week of May</p> </td> <td> <p class="s9">Vigorous, consistent production of good, medium-sized fruit.
