According to Gardening Central, the daisy tree, though native to tropical regions, can survive in any climate with temperatures that don't drop below -6.67 degrees Celsius (20 degrees Fahrenheit). However, in climates that are colder than this, you can plant this tree in a pot to bring inside for the winter. Most daisy trees produce white blossoms, yet there are a few varieties of yellow-flowered trees. No matter where it's planted, giving this plant the same type of growing conditions it would receive in the tropics is imperative for its survival.
Walk over to the proposed planting location. Make sure that it receives full sun and is free of wind. Areas next to fences, outdoor structures, large hedges or trellises work well to block the wind for this plant.
Dig a 45 cm (18 inch) hole in the designated planting location to perform a percolation test or soil-draining test. The width is not relevant. Fill the hole with water and allow the water to absorb into the soil overnight. Refill the hole in the morning and measure the water line at the top. Wait one hour and remeasure. If the water has drained 1.2 to 2.5 cm (1/2 inch to 1 inch), it has adequate drainage. Anything else means you must spread 7.5 cm (3 inches) of compost and builder's sand over the area to improve its drainage. Daisy trees must be planted in an area with well-draining soil.
Make a hole that is twice the size as the daisy tree's root ball and at the same depth as the tree was planted in, in its nursery container. Place the daisy tree inside the hole and pack soil around its base to reduce air pockets.
Press one stake into the ground that is two-thirds the height of the daisy tree. Hammer in another stake on the opposite side. Tie a string from one stake around the daisy tree and back to the stake. Loop a string from the stake around the daisy tree and back to the stake. Make sure that the string is tied loosely.
Water the tree to moisten the soil. Spread 7.5 cm (3 inches) of mulch, from the base of the tree to the dripline.
Prune your daisy tree with bypass shears to remove damaged or diseased portions from the tree after it has stopped blooming.
Monitor the string on your daisy tree to make sure that it is not stunting the tree's growth. Re-tie the string up the stakes as the tree grows.
