I don't know if you're willing to sacrifice appearance for a year or so in order to make sure the tree's structure is something you can build on, but here's what I wold do. I think I'm seeing a node on the natural branch toward the top of the tree where a leaf has been shed. If that is true, I would prune that upper branch back to 1 leaf, and cut that leaf in half against venation (the veins in the leaf). The reason is, it's a very good thing to have a branch growing from the first 2 nodes immediately distal to the trunk or lower order branch. For reference, the trunk or main stem of a plant is considered to be the first order branch. A branch growing from the trunk/stem is a second order branch. Second order branches give rise to the third, ad infinitum. The reason it's a very good thing to have a branch growing from the first 2 nodes immediately distal to the trunk or lower order branch is because it will produce a highly refined tree, one with leaves and branch density as compact and dense as can possibly be achieved by way of pruning/pinching practices. Not to worry about cutting the most distal leaf (and the only leaf) leaf on the branch half. It will not remain as part of the composition. A new branch will form in the axil of that leaf. When the first leaf on the new branch is starting to unfurl, remove the half leaf. Also, it looks like there is a leaf at the base of that branch. That leaf should be removed now; or, if you think it enhances the tree's appearance, remove it when the new branch starts growing where there is now only a leaf/bundle scar. There are dormant buds immediately distal to that scar that will be activated. The reason for cutting the leaf in half is, it further reduces the amount of auxin produced . Auxin is mainly produced in the branch apex (growing tip of the branch) but also in leaves and especially in young leaves. The more you can limit auxin flow in the branch, the more likely back-budding becomes. There are many untapped resources/techniques the hobby grower can take from the art of bonsai and apply to make a huge difference in their plants' vitality and appearance. For an upright tree: Think about how tall you want it to be from the floor, maximum ht.. The lowest branch on the tree should be growing from the trunk at a ht. somewhere between 1/2 - 2/3 of what you expect the tree's o/a ht to be. There are exceptions. Sometimes a low 2nd order branch can serve visually as a branch higher on the tree. Example: In this mother/daughter style maple, the daughter "tree" makes the composition a twin trunk style, but visually it serves as a branch. Your tree has that potential if you want to work toward it, utilizing the low branch. I think your tree is too tall. It looks like it's already close to being maxed out on ht.. I would prune the top back to the first leaf distal to the shrink wrap, and cut that leaf in half. Essentially, a repeat of what you did with the upper branch growing to the right. When the 2 new 2nd order branches occur near the top, they should be trained to about a 45-60* angle off the vertical axis. If you look at a mature tree in nature, you'll see the bottom branches are closer to horizontal with maybe the tips of branches upswept a bit. As you move up the tree, the angle between the second order branches and the trunk gradually decreases. Try ti mimic that for a more attractive tree. Al

@JMJ 4Life Really sorry to learn about your tree. I assume some part of the root mass is fused, so the soil/root mass remains intact like so: If the answer is yes, unpot the plant and set the root/soil mass on a stack of newspapers, rags, old towels, dry sponges - something that will PULL excess water from the soil. Allow it to rest on the wicking material for an hour or two before returning it to the pot it fits. Use a wooden "tell" to "tell" you when it's time to water, because with no water loss from foliage, the plant will require very little water. Using a 'tell' Over-watering saps vitality and is one of the most common plant assassins, so learning to avoid it is worth the small effort. Plants make and store their own energy source – photosynthate - (sugar/glucose). Functioning roots need energy to drive their metabolic processes, and in order to get it, they use oxygen to burn (oxidize) their food. From this, we can see that terrestrial plants need plenty of air (oxygen) in the soil to drive root function. Many off-the-shelf soils hold too much water and not enough air to support the kind of root health most growers would like to see; and, a healthy root system is a prerequisite to a healthy plant. Watering in small sips in order to avoid over-watering leads to a residual build-up of dissolved solids (salts) in the soil from tapwater and fertilizer solutions - which limits a plant's ability to absorb water – so watering in sips simply moves us to the other horn of a dilemma and creates another problem that requires resolution. Better, would be to simply adopt a soil that drains well enough to allow watering to beyond the saturation point, so we're flushing the soil of accumulating dissolved solids whenever we water; this, w/o the plant being forced to pay a tax in the form of reduced vitality, due to prolong periods of soil saturation. Sometimes, though, that's not a course we can immediately steer, which makes controlling how often we water a very important factor. In many cases, we can judge whether or not a planting needs watering by hefting the pot. This is especially true if the pot is made from light material, like plastic, but doesn't work (as) well when the pot is made from heavier material, like clay, or when the size/weight of the pot precludes grabbing it with one hand to judge its weight and gauge the need for water. Fingers stuck an inch or two into the soil work ok for shallow pots, but not for deep pots. Deep pots might have 3 or more inches of soil that feels totally dry, while the lower several inches of the soil is 100% saturated. Obviously, the lack of oxygen in the root zone situation can wreak havoc with root health and cause the loss of a very notable measure of your plant's potential. Inexpensive watering meters don't even measure moisture levels, they measure electrical conductivity. Clean the tip and insert it into a cup of distilled water and witness the fact it reads 'DRY'. One of the most reliable methods of checking a planting's need for water is using a 'tell' (more reliable than a 'moisture meter'. You can use a bamboo skewer in a pinch, but a wooden dowel rod of about 5/16” (75-85mm) works better. They usually come 48” (120cm) long and can usually be cut in half or in several pieces, depending on how deep your pots are. Sharpen both ends of each tell in a pencil sharpener and slightly blunt the tip so it's about the diameter of the head on a straight pin. Push the wooden tell deep into the soil. Don't worry, it won't harm the root system. If the plant is quite root-bound, you might need to try several places until you find one where you can push it all the way to the pot's bottom. Leave it a few seconds, then withdraw it and inspect the tip for moisture. For most plantings, withhold water until the tell's tip comes out nearly dry. If you see signs of wilting, adjust the interval between waterings so drought stress isn't a recurring issue. Al

Insofar as how it would impact root health, there is no difference between plastic and high-fired clay/ceramic. If you can see no crazing (myriad small cracks reminiscent of a fish net with small holes) in the glaze, you can eliminate anything toxic making its way from the pot to the grow medium. If you haven't fertilized or used any type of tonics, insecticides, leaf shine, detergents, etc., it's a very good bet you have unwittingly over-watered due to the fact there is no way for water to evaporate or be used by the plant as the new medium is not colonized by roots and remains a hostile environment to roots due to lack of oxygen. My suggestion would be to lift the plant from the pot to see it the lower reaches of the soil column are saturated. If so, see figure D below. Remove the soil from the new pot, place an over-turned pot in the bottom of the pot so it fits snugly, and cover the drain hole of the over-turned pot with something that won't rot (it does not need to allow water to drain through the hole in the over-turned pot, but it's ok to use a screen if you wish). Mix enough of the soil that falls away from the roots or remains in the large pot with an equal measure of perlite and fill to the top of the over-turned pot, then reposition your plant on top of the pot. and back-fill with the remaining soil w/o the extra perlite. The shaded areas in the images above represents perched water. By comparing D to A, you can see the over-turned pot significantly reduces the amount of excess (perched) water your soil will b e able to hold, so air will return the the soil much faster. The operational words for the moisture level of a grow medium is damp/moist, never wet/soggy. After having put the pot to work as ballast, start checking moisture levels with a "tell" you can make from a wooden dowel rod. It is far superior to a finger or a "moisture meter".

Well that's bad news. Wait, where are my manners, I should have said thank you. I really do appreciate your sharing your knowledge. Carrotwood, huh. Since it is invasive and threatening and since we're within a stone's throw of the river (and Mangroves) it will have to go. Thank you for the head's up. Bummer.
