Air Layering A Plant That Has Gotten Too Tall

Fasten each end of the plastic securely, to retain moisture and to prevent water from entering. If exposed to the sun, the plastic should be covered. Aluminum foil can also be used, as it does not require twist ties or tape to hold it in place.

When you see a critical mass of roots, you can sever the branch from the plant completely by cutting about 1” below the propagation site. The only real difference between air layering and cuttings is the fact that you remove the stem completely when taking a cutting. Taking cuttings is a better technique for smaller, younger stems as they can survive off of capillary action delivering water and nutrients to the plant. For optimum rooting make air layers in the spring on shoots produced during the previous season or in mid-summer on mature shoots from the current season’s growth. On woody plants, stems of pencil size or larger are best.

Removing a section of skin from the lower-facing stem part before burying may help the rooting process. If using rooting hormone, the stem should be cut just beneath a node. The resultant notch should be wedged open with a toothpick or similar piece of wood and the hormone applied before burying.

What Is Air Layering?

Genera that form stilt roots include Pandanus, Clusia, Tovomita, Elaeocarpus, Xylopia, Dillenia, Eugenia, and Musanga. Adventitious roots arise after injury to roots or from main stem, branch, or other tissues. Prior to their emergence from the parent root, adventitious roots differentiate an apical meristem, root cap, and the beginning of a vascular cylinder.

Most residues are degraded enough not to be an issue. Get enough of the compost to fill several small pots. Fill 4 pots with the compost and 4 with the trusted medium. I don’t have an issue as the local place I get compost is an organic turkey farm. The other composts the yard waste generated here in the mountains, which is pine needles, chipped branches and such things so those type chemicals are minimal. However, it has been found that the trees here are laden with chemicals absorbed from when this was a lumber mill and mining economy town.

Adventitious Roots

You want it to be only slightly larger around than the cane so it won’t lose moisture or the coir when you water. If you don’t want to fuss with the water bottle here are some Rooter Pots you can use, they are made for this. I used peat moss for this because someone had given me a couple bags but usually I use coconut coir mixed with a touch of potting soil. The addition of 2g/L polyvinylpyrrolidone significantly reduced the oxidative browning of explants of both species. Approximately 40% of plantlets were successfully hardened under greenhouse conditions. A marcott set on a vertical shoot from a decapitated branch of Dacryodes edulis.

At this time the bark is slipping and easily removed. Air layering plants requires a moist environment for aerial roots to form. We now have to create a good environment for roots to develop. We will use long-grain sphagnum moss or peat moss to do that. You should be able to find these at your local garden center or discount store in the plan section. If you cannot find the sphagnum moss, the peat moss will work too, it will just be a little trickier.

In the former, soil mounds are built around the shoots emerging from coppiced stumps and then the rooted shoots are severed from the stump and planted. This typically captures the juvenile characteristics of the tree associated with the base of the tree trunk. In the former, soil mounds are built up around the shoots emerging from coppiced stumps and then the rooted shoots are severed from the stump and planted. Air layering is usually applied to mature branches within the tree crown, usually a long way from the ground (Tchoundjeu et al., 2010). As layering does not involve sexual reproduction, new plants are effectively clones of the original plant and will exhibit the same characteristics.

Moisture must not escape and excess moisture must not enter when watering or syringing the plants. Support the plant with stake or splint to prevent breakage at the wounded area.

The mangroves are good examples of trees that produce stilt roots but they also form in a number of trees found in fresh water swamps and rain forests.

This is important for plants that form roots slowly, or for propagating large pieces. Layering is used quite frequently in the propagation of bonsai; it is also used as a technique for both creating new roots and improving existing roots. Air layering is a procedure used to induce roots to form on a plant stem while it is still attached to the parent plant.

Woody ornamentals such as azalea, camellia, magnolia, oleander, and holly can also be propagated by air layering. For optimum rooting, make air layers in the spring on shoots produced during the previous season or in mid to late summer on shoots from the current season’s growth. For woody plants, stems of pencil size diameter or larger are best. Choose an area just below a node and remove leaves and twigs on the stem 3 to 4 inches above and below this point. This is normally done on a stem about 1 foot from the tip. Simple layering can be accomplished by bending a low growing, flexible stem to the ground.

I have yet to try grafting, I really want to and should. Once you have a good mass of roots it is time to sever the cane and pot it up. I close it back up and let the roots get longer and stronger before severing the cane below the roots and potting up. If you look at the photo below you will see white nodules, that is a sign of roots beginning even if you don’t see any actual roots yet. After 4 weeks open it up gently and check to see if you find roots or signs of them developing. You then need to peel or scrape away the green layer with the sharp knife to reveal the white layer.

Plant Propagation

Be careful not to cut too deep or your cane will snap off. Just get deep enough to be able to peel away the green layer. First I make two cuts into the green layer approximately an inch and a half apart all the way around the cane. This is where the lighter weight water bottles are handy, they are easier to cut through. I have wimpy hands right now because of carpal tunnel so I go for easier.

Many plants are lost in the final stage of the process because the root system is not sufficiently developed to sustain the top portion of the new plant. Once the plant is well established, it is best to harden off the foliage by gradually exposing it to normal atmosphere. This can be done by cutting a few holes every few days in the plastic tent to reduce the humidity until it is similar to the external atmosphere.

Be careful not to disturb the roots or sphagnum moss. Keep the new plant well-watered and out of direct sunlight until the new root system is well developed. For optimum results, select branches that are the size of a pencil or larger.

Choose the stem on your plant that you want to propagate and the section you will cut. A good rule of thumb is to cut a 4-6 inches below a node. Finally, you wrap the moss in a plastic wrap of some kind and secure it with rope or string. If you want an exact copy of a particular plant you love, you have to propagate off of it directly…that’s how you guarantee you clone it. Air layering uses existing plant material, so it produces genetically identical clones.

Some plants propagate naturally by layering, but sometimes plant propagators assist the process. Layering is enhanced by wounding the stem where the roots are to form. The rooting medium should always provide aeration and a constant supply of moisture. Stems that are still attached to their parent plant may form roots where they come in contact with a rooting medium. This method of vegetative propagation is generally successful, because water stress is minimized and carbohydrate and mineral nutrient levels are high. The development of roots on a stem while the stem is still attached to the parent plant is called layering.

Cover the ringed area with a handful of presoaked sphagnum moss from which the excess water has been squeezed. Wrap this tightly with medium weight plastic wrap and secure with twist ties above and below the ball of moss. (These ties may not be necessary.) Cover this ball with a square of aluminum foil, dull side out to discourage birds from pecking. To learn how to air layer, you need to consider how to get the plant material to root.
