Inducing adventitious budding
I have a cutting from an old Sequoia Sempervirens (Coast Redwood) that is rooting like crazy. It took 1.5 months in a fogponic/aeroponic cloner, as well as large doses of IAA, IBA, and NAA in the water before it started to callus and show root primordia. I then transfered the cutting into soil, and since then the number of roots has increased to at least 9 roots (judging from the roots that have grown to the edge of the clear container the cutting has been planted in). There are likely more roots than 9, but most of the roots have not grown to the sides of the container yet.
My worry is that the cutting is continuing to grow more roots, longer roots, etc, and I am not seeing any growth up on top. No new buds, no new shoots, no elongation, no new leaves, etc. What is the best way to initiate new bud growth, new shoot growth, etc? Are there any hormones that can help?
