Glen, in Melbourne, wants to know the best time to transplant a well-established frangipani tree from a pot to the soil, and should he do anything to the soil. The best time to transplant Frangipani is at the end of winter, while the tree is still dormant but close to breaking dormancy. In Warm climates, this can be done from the second week in August (during a Full Moon phase) but, as Melbourne has some more cold weather to come, Glen would be wise to wait until early September. Before planting any tree it is wise to check soil drainage, and this is extremely important for Frangipani as they won’t tolerate wet feet. (See Planting trees ) If soil is on the heavy side, some coarse river sand can be mixed through the soil used to fill the hole. The hardest part about transplanting Frangipani is getting them out of the pot because their roots are very brittle and can snap off if jolted, especially if the plant is large. If the tree is in a plastic pot, the safest way is to cut the pot away to remove the tree. If the tree is in a very sturdy pot, run a piece of wire around the inside rim of the pot to loosen the root ball, or hose gently around the inside edge of the pot. Then gently turn the pot on its side and ease the tree from the pot. If the pot has a large hole in the base, a broom handle or dowel can be used to gently push the root ball from the base. After settling the tree in its new location, water gently to settle the soil but do not tramp the soil down. Apply a 5 cm layer of mulch when soil has warmed, keeping mulch clear of the trunk to avoid collar rot. Although the Frangipani is very drought tolerant, the tree will need regular watering until established. Water when the top cm of soil is dry.
