Horridculture – Salvage

A hedge of a dozen like this came from one branched stump.

This is an old and redundant topic. I should know better. Some vegetation is not worthy of salvage. Even that which is worthy can become excessive if too much is salvaged. The problem is that I find it very difficult to discard vegetation that I can relocate to another landscape, or grow in the recovery nursery whether or not we have use for it.

A few stumps of shrubbery needed to be removed from a small landscape of one of the buildings at work. With one exception, the shrubbery was common Photinia X fraseri, which had been cut down some time ago, and had not grown back much. The one exception was a common Escallonia rubra, which had been cut down even earlier, so had grown back about five feet tall, with a few distinct trunks.

I had no problem discarding the Photinia X fraseri. The stumps came up with mostly severed large roots, and very minimal fibrous roots that they needed to survive. If I really want to grow more, it would be more practical to grow it from cuttings. I am none too keen on the species anyway.

The Escallonia rubra was not so simple. Although I was determined to discard it all, and I am no more fond of the species than I am of Photinia X fraseri, it came out with more than enough fibrous roots to survive relocation. What is worse is that the several trunks were easily divided into several individual well rooted specimens, with several more layered stems attached to them. I assembled an even dozen well rooted specimens as a hedge outside a fence of our maintenance shops, and nine smaller rooted cutting to alternate between cypress trees outside another similar fence. Although pleased with the results, I should have discarded them.

This is one of the smaller well rooted specimens, although the layered stems are smaller.

Layer To Propagate Favorite Plants

Ivy takes root as it grows.

Ivy is creepy. It creeps everywhere. As it does so, it extends roots into or onto whatever it creeps over. Not only does it do this to climb, but it also does this to propagate. It literally roots as it goes, to function more as a swarm of countless small plants instead of a single big plant. A bit of well rooted stem may grow independently from the original as a ‘layer’.

Many vines do the same, even if they are normally climbing vines that just happen to fall onto the ground. A few shrubs and trees, especially riparian sorts, are happy to do it also if lower limbs lay onto damp soil. Such a rooted stem is known as a layer because it lays on the ground to root. In a home garden, a layer might root below a layer of mulch or soil. 

In fact, many plants in home gardens are easy to propagate by intentional layering. Many develop roots more reliably if layered than if propagated from cuttings. They grow almost like cuttings, but while attached to the original plants to sustain them. Layering produces only one or a few new plants, unlike cuttings, but for most home gardens, that is enough.

Some plants are easier to layer than others. Pines and most eucalypti are uncooperative to the technique. Rhododendrons, azaleas and camellias layer relatively easily, but may take more than a year to finish. Elms and magnolias are even happier to layer, but rarely retain low stems. Some plants layer best after spring bloom. Others layer through winter.

An intentionally layered stem should be partially buried, with a few inches of stem below the soil, and a few inches of the tip of the stem protruding above the soil. Notching about a third of the way through the underside and applying rooting hormone promotes rooting. Regular watering is necessary through the process, which continues at least until winter.
