How to propagate trees from cuttings
Hey, if you have a tree which you want to clone, but don't want to use complicated methods, look no further. I have recently experimented this method on Asian pear trees, and it works great.
Root Hormone (I used powdered)
Healthy cuttings from a tree of your choice
Local soil (I haven't tried vermiculite yet)
White plastic trash bag
Step 1: Attain healthy cuttings from a healthy tree. Remember to always ask permission if you are taking cuttings from someone else's tree. Try to aim for 4-8" cuttings for small trees (such as dwarf fruit trees), and 10-15" cuttings for large trees (such as oaks). Smaller trees will root faster. Try to cut cuttings off of the tree at 45 degree angles.
Step 2: Fill the pot up with soil, and moisten the soil with a sprayer. Create 8" deep holes in the soil for the cuttings. I would recommend no more than four cuttings in a pot with a top diameter of 14".
Step 3: Remove the bark off of the bottom 1/3 of the cutting. Put the bark-less part of the cutting into a glass of water for five minutes. Then, dip the bark-less part of the cutting into the rooting hormone, and GENTLY place it into the already-prepared hole. Try to space the cuttings evenly, and not too close.
Step 4: Gently firm the soil around the cuttings, and mist them. Then, place the pot in the white, plastic bag, and tie the top. I found it works well to gently mist the inside of the plastic bag, as well. Place the pot in place OUT OF DIRECT SUNLIGHT. You may think you need sunlight to root the cuttings, but the sun will dry up the soil. The cuttings do not need to be in a completely dark place, but a medium between bright and dark would be nice.
Step 5: Mist the cuttings EVERY OTHER DAY unless the soil is visibly dry (you can tell this because the soil will crack when dry). Also, try not to water too much, because the cuttings will rot. Although it is tempting, do not remove the cuttings to check on them. Actually, don't look at them at all for the first two weeks (except when watering). Don't worry, they will let you know when their ready. After about a month, smaller trees will begin to grow small leaves and shoots.
It would be best to wait until the trees are big enough to survive the elements before you transplant them. So, in essence, don't put them outside at first sign of growth. Wait about three months after the first sign of growth to do this.
