    It may be tedious, but the best thing would be to dig up everything that you can, and pour boiling water on the rest. This will kill anything that it comes into contact with without leaving the soil toxic. This is the method that I use, and it does take a few applications, but it will kill just about anything.

    "Dwarf white sands" and "Little White" and other dwarf varieties are described at 3 to 6 feet mature height, so maybe a little small for your 5 -
    10 foot requirement.
    "Sister Agnes," a cultivar with single white flowers, grows to between 10 and 12 feet in height.

    If you have full size oleanders and not a dwarf variety then 5 to 6 feet spacing will be perfect in time. 2 years is young and not nearly developed.
    Water an fertilizer will stimulate growth. Shaping the tops down a little may stimulate lateral growth.
    Lower branch growth depends on sunlight to the lower part of the plant, adequate water and nutrients, and maybe pest control if there are aphids or scale insects feeding.

    Trimming them is not necessary, but it will not hurt them at all either. This is a way to shape them as you would like them. This article will help: https://www.gardeningknowhow.com/ornamental/shrubs/oleander/pruning-oleander-shrubs.htm

    That is, certainly, an infection. There are many kinds from bacterial, to fungal, to viral.

    Most can be cured easily. The best way for a potted plant will be to replace 1/4 of the water with peroxide the next time that you water. This will kill off the infection. You will only have to do this once, and when it is needed in the future.

    Thanks that’s most helpful and an entirely new approach. I presume that’s 1/4 at 3% peroxide concentration ?
