Herbaceous stems cortex


In general, plants that die after going from seed to maturity within one growing season (annuals) have green, herbaceous (nonwoody) stems. Most monocots are annuals, but many dicots are also annuals.
The tissues of annual dicots are largely primary, although cambia (plural of cambium) may develop some secondary tissues. Herbaceous dicot stems have discrete vascular bundles composed of patches of xylem and phloem. The vascular bundles are arranged in a cylinder that separates the cortex from the pith, although in a few plants (e.g., foxgloves), the xylem and the phloem are produced as continuous rings (cylinders) instead of in separate bundles.

The procambium produces only primary xylem and phloem, but later, a vascular cambium arises between these two primary tissues and adds secondary xylem and phloem to the vascular bundles. In some plants, the cambium extends between the vascular bundles, appearing as a narrow ring, producing not only the conducting tissues within the bundles but also the parenchyma cells between them. In other plants, the cambium is not in an uninterrupted cylinder but is instead confined to the bundles, each of which has its own small band of cambium between the xylem and phloem.

You were correct in eliminating some of the leaf surface and making a shallow wound in the base of the stem.
For soft wood stem cuttings one usually makes a clean cut just below a node in the stem and then a one inch sliced wound .
You may not have lost the plant. Roots may form this autumn.
The leaves may have fallen from drying out or perhaps a fungus formed in the soil
With evergreen leaf cuttings I sometimes will put plastic over the cuttings to keep the humidity up .
Environmental control such as stress, too much water, not enough light or a soil fungus appearance are all plausible reasons for the leaf drop

DALY: Use care when planting around septic drainfields  — Gwinnettdailypost.com
Shallow rooted annual and perennial herbaceous plants can be planted closer to the drain fields since they do not have invasive roots. Turfgrass can be grown over the drain field and is beneficial since it helps hold the soil in place.
