How to Grow Apricots Once you’ve selected your cultivar, you need to know how to grow apricots. Site selection and soil are the most important considerations. The trees need deep, well-drained soil with plenty of organic matter. Apricot trees bloom early. There are times in apricot tree care where a late frost is a problem, so be sure to plant your trees on higher ground. Do a percolation test prior to planting by digging a hole one foot deep and wide (30 cm.). Fill with water and wait until the next day. Fill the hole again and lay a stick or straight edge over the top. Measure the water drop every hour. Ideal readings will be around 2 inches (5 cm.) per hour. Once you have adjusted the soil to have adequate drainage, dig a hole twice as deep and around as the root ball and plant your tree. Water in well.
