How to Grow an Almond in a Container
To grow an almond tree in a pot, start with a container that holds at least 10 to 20 gallons (38-75 L.) of potting soil. Be sure the pot has at least one good drainage hole. Consider a rolling platform or container because your container-grown almond tree will be very heavy and difficult to move. Mix in a generous amount of sand; a container-grown almond tree needs coarse soil. The following tips on growing an almond tree in a pot may be helpful as you’re starting out: An almond tree in a pot is happiest with temperatures between 75 and 80 degrees F. (24-27 C.). Place container-grown almond trees safely away from drafty windows and air-conditioning vents when indoors. Once cooler temps approach, you’ll have to bring your tree inside. Place the almond tree in a window where it receives afternoon sunlight. Almond trees require lots of light, so provide artificial light if natural light is insufficient. Water your almond tree deeply until water trickles through the drainage hole, then don’t water again until the top 2 to 3 inches (5-8 cm.) of soil feels dry to the touch – usually about once a week depending on temperature. Never allow the pot to stand in water. Keep in mind that the tree will tolerate lower light and decreased water when it enters dormancy during the winter months. Prune container-grown almond trees yearly during the dormant period. Almond trees can reach 35 feet (11 m.) outdoors, but they can be maintained at about 4 to 5 feet (1-1.5 m.) in containers. Fertilize your almond tree in spring and fall after the first full year using a high-nitrogen fertilizer.
