My Michelia figo new leaves keep changing brown and fall off?

Question

I have a Michelia figo in pot for a year. It is fine and has a lot of flower until this spring after the flower is finished. All leaves are dropped. Then new leaves are starting, but new leaves are soon changed to brown and fallen off as well before they are mature and turn to dark green.

Could you guy help me to save this poor plant?

Answer 1

The plant putting out new leaves, that turn brown and fall off soon after, sounds like a salt problem in the soil. Salts accumulate in the soil from fertilizer and water applications over time, particularly when a potted plant is watered in such a way that very little, or no, water runs out of the bottom of the pot when it is watered. This problem can be quickly fixed. Put the pot outside and water it until the soil is completely saturated with water. Then fill the pot with water five or six times, allowing the water to run freely out of the drain holes in the bottom of the pot each time. Be sure the pot does in fact have drain holes, and that they are not plugged up.
Given that you have had the plant for a year in the same pot may mean that it needs to be planted into a larger container. This would add some fresh soil around the root ball for new roots to grow. Good luck.

Answer 2

It does sound like your plants are healthy, but see below for your info: Verticillium Wilt Verticillium wilt symptoms on tomato, potato, and eggplant are similar to those of Fusarium wilt. Often no symptoms are seen until the plant is bearing heavily or a dry period occurs. The bottom leaves become pale, then tips and edges die and leaves finally die and drop off. V-shaped lesions at leaf tips are typical of Verticillium wilt of tomato. Infected plants usually survive the season but are somewhat stunted and both yields and fruits may be small depending on severity of attack. A light tan discoloration in the stem similar to that caused by Fusarium wilt may be found but is usually confined to lower plant parts. The discoloration is typically lighter in color than with Fusarium wilt.
