I like your second strategy, i.e., add more soil in a larger pot around the air-layer. Thank youYup, looks about right.
Note: You have a fairly small rootball for the amount of foliage. An alternative strategy could be, considering it is early in the year, to either trim the layer back now, and wait for it to start sprouting. Of if you want to grow out the layer, and would like to keep as much foliage as possible, to put a larger pot around the layer and let it root a month longer with more space, fertilizing and watering the pot as normal, end separate later in spring.
Thank you, Neil. These are great pointers for me. I will keep an eye on the roots/watering situation inside the bag and make sure the roots don’t dry out.I would be happy to let the roots grow a little more in the current bag. At this time of year it should not take long to grow a lot of roots.
I have found that you need to be watchful at this stage. The new roots are removing a lot of moisture from the bag for all those leaves above. Some layers I have left just a bit too long died and it seemed to me they dehydrated after using all the water from the bag.
A larger bag/pot as suggested will work but probably more work than necessary. A modest prune when you take it off would be easier and the lost foliage should be replaced pretty quick at this time. I have found that layers can survive even if they have what looks like few roots for the branches above. Roots are growing fast now and the layers seem to be able to focus attention on more roots when they need to.
Good point. The bottom of the pot has a ton of holes. I will put it flush on a bed of pea pebbles. Several of mine with a similar set up throw down roots and show vigor pretty quickly.If you want the nebari to improve, you need to give the tree a reason to grow new roots, and the option to do so. It seems this tree is not potted deep enough to really do this.
