The Canary Island palm tree (Phoenix canariensis) is a large, date-producing palm that can grow to over 60 feet tall. It is a tropical plant hardy to 20 degrees F that does well in USDA climate zone 9 . The date that this tree produces is an orange fruit that is said to be inferior in taste to that of its cousin, the traditional date palm, or Phoenix dactylifera. This palm is recommended for areas where it will have lots of room to spread because the canopy can reach 35 feet in width.
Plant your Canary Island palm tree in an area that receives full sun and where it will have lots of room to spread as it reaches maturity. Dig compost into well-drained soil and then set your young tree into your planting hole. Water it well after you plant it.
Water your Canary Island palm tree deeply about once a month after it is established. Because it is drought tolerant and thrives during prolonged dry spells, do not over-water this tree.
Prevent the giant palm weevil from attacking your tree by spraying a preventive insecticide on the tree after you transplant it and until it is well established. Consult with a landscape specialist to learn what product is best to use and how to apply it.
Fertilize twice a year with a plant food designed for palms. This tree can suffer from a deficiency of magnesium or potassium; if your palm develops yellow leaves fertilize it with a plant food high in these two nutrients.
Trim your Canary Island palm tree to keep dead fronds and thorns from detracting from its appearance and to make the tree safer to be near. Using a tree saw or large loppers, cut all lower fronds off at their base. Snip off thorns, being very careful not to allow them to puncture your skin. After you prune all but the highest fronds, skin the stumps of the fronds back to the trunk, leaving a “pineapple,” or bulbous clump, about 2-feet high just below the remaining fronds.
