In today’s post, we will show you 5 sure shot air layering tricks and garden hacks to multiply those so called difficult-to-propagate plants with 100% results using different methods of air layering trees. Finally, a Secret Bonus tip on air layering in the end.
Introduction
When it comes to propagating or multiplying plants, our mind usually jumps to taking branch cuttings and trying to root them, but most often end up with poor results. But what if I told you that there are 5 different ways to multiply plants with 100% success results, especially for those difficult-to-root trees or woody or semi-woody branches? Even a newbie gardener can easily succeed in these methods. Moreover, these methods will produce genetically identical new plants which will carry all the characteristics of the parent plant. Let’s start these one by one.
5. Simple Layering
This is the easiest method and many a times this process occurs naturally. This can be accomplished by bending a low-growing or a flexible branch to the ground. You can optionally injure or strip the outer bark to expose the cambium layer of the branch for faster rooting. You can optionally apply a rooting hormone powder if you have. Then, cover part of it with soil, leaving the remaining 6 to 12 inches above the soil. You can keep some weight over it to prevent it from coming out of loose soil. Make sure you keep watering your plant regularly. The rooting will start within 4 weeks. Once you see roots, you can separate it from the mother plant and transfer it to an independent container.
4. Tip Layering
This is quite similar to the simple layering method. Dig a hole and insert the tip of a plant branch shoot and cover it with soil. The tip grows downward first, then bends sharply and grows upward. Roots form at the bend.
3. Classic Air Layering
This method has two variations depending on whether the plant is a monocot or a dicot. This is actually very interesting.
Differences Between Monocot and Dicot Trees
- Monocot: One Cotyledon, parallel veins, fibrous root system, floral petals usually in multiples of three.
- Dicot: Two cotyledons, branching veins, tap root is a must, floral petals usually in multiples of four or five.
Alternately, if you know the name of the tree, you can simply google it to find out whether it’s a monocot or dicot.
For Monocots
Make an upward 1 to 1½-inch cut about one-third through the stem. The cut is held open with a toothpick or wooden match stick or any small piece of plastic. Now you need a growing medium or air layering mix. This can be a simple peat moss, cocopeat, sphagnum moss, or even just plain soil. Here I am using a mixture of cocopeat and compost. You have to make it fully moist first and then wrap around a polythene sheet and surround the wound with this air layering mix, about a handful of it. Hold it in place tightly using anything to tie around at both ends, like cable ties, twist ties, electrician’s tape, strings, or whatever you have. Tie 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 by any dark cloth or aluminum foil if you have.
For Dicots
The process is similar, except a 1-inch ring of bark is removed from the stem. With a sharp knife, make two parallel cuts about an inch apart around the stem and through the bark and cambium layer, just below a node. Connect the two parallel cuts with one long cut. Remove the ring of bark, leaving the inner tissue exposed. Scrape if necessary to properly peel the tissue and to prevent a bridge of callus tissue from forming. Apply some rooting-hormone powder to the exposed wound if you have. But this is optional. Then wrap around a polythene sheet and surround the wound with the same air layering mix. Then tie both ends with cable ties, twist ties, or string or anything. If exposed to the sun, the plastic should be covered by any dark cloth or aluminum foil if you have. Rooting should start within 4 weeks. You can open it after 4 to 6 weeks to see the roots filling in and then cut off this branch below this level and plant it independently.
2. Pot Layering
This is just a variation of classic air layering methods. You use pots for air layering in this method. Just strip off the bark with a sharp knife to expose the inner tissue. Now cut through a plastic pot and fix this to the branch. You can use anything to tie it properly to the branch, like duct tape, cello tape, or strings. Fill the pot with the potting mix. And finally, water this and cover it with a polythene cover to retain moisture. Rooting should start within 4 weeks. You can open it after 4 to 6 weeks to see the roots filling in and then cut off this branch below this level and plant it independently.
1. Water Layering
This is another variation of air layering where we use water as a growing medium. This is very useful for monocots but also works on dicots. Take any waste plastic bottle and cut a small window at its upper middle part. Now make an upward 2-inch cut about one-third through the stem. Then the bottle is introduced through this cut and fixed using some strings or ties. Fill the bottle with water. Make sure you support the branch with some stick or support or else the branch can break off easily. If exposed to the sun, this can be covered by any dark cloth. You can add a quarter tablet of aspirin 350 mg to this water for faster rooting. Aspirin is acetyl salicylic acid which helps in faster rooting. Roots start as early as 10 days. You can cut off this from the mother plant and replant it to an independent container.
Bonus Tip: Adding Aspirin
Adding an aspirin tablet – like one tablet in 1 liter of water and mixing it with the air layering mix to make it moist. For bottle or water layering, you can drop a quarter tablet directly into the bottle. For pot layering, you can water the pot with this solution and for classic air layering, you could mix it while wetting the mix or if you have forgotten, you can load it in a syringe and inject it into the mix.
