How to Root a Mulberry Bush From Cuttings
The cuttings must be treated with rooting hormone and kept under sheltered conditions to produce the most reliable results.
Things You Will Need
6-inch square pot
Perlite
Coarse sand
Bypass shears
12-percent IBA (indolebutyric acid) rooting hormone
Propagation mat
1-gallon nursery container
Loam
1. Prepare the Rooting Container for Mulberry Tree Propagation
Prepare a rooting container before gathering the mulberry cutting. Fill a 6-inch square pot with a mix of half perlite and half coarse sand. Pour water onto the mixture and let it drain for 20 minutes.
2. Choose the Mulberry Cutting
Gather a 4- to 6-inch-long cutting from a lateral mulberry branch. Choose one with soft, pliant growth at the tip and semi-hardened wood at the base of the stem. the best time to do this is when you perform your spring pruning.
3. Collect and Prepare the Cutting
Sever the mulberry cutting at a 45-degree angle just below a set of leaves. Use sharp, sturdy bypass shears to sever the cutting. The University of Florida IFAS Extension advises that you should strip off the foliage along the lower half to two-thirds of the cutting's stem.
4. Treat the Cutting With Rooting Hormone
Dip the defoliated end of the mulberry cutting in 12 percent IBA rooting hormone. Gently shake the cutting to release the excess hormone. Pot it immediately.
5. Plant the Mulberry Cutting
Poke a planting hole in the center of the perlite mixture. Make the hole just long enough to hold the hormone-treated end of the cutting. Insert it into the planting hole and press the perlite mixture snugly against the stem.
6. Set the Potted Cutting Outdoors Out of Direct Sun
Place the potted mulberry cutting in a lightly shaded cold frame or outdoors in dappled shade. Shield it from direct sun, because the heat and intense light will stress the cutting.
7. Apply Bottom Heat
Apply 70 to 80 F bottom heat to the pot using a propagation mat. Keep the mat on all day and night during the rooting process.
8. Mist and Water the Cutting
Mist the foliage and stem with a spray bottle daily in the mid-morning and mid-afternoon hours. Check the moisture level of the perlite mixture when you spray the foliage. Moisten it whenever it feels dry in the top inch.
9. Check for Rooting
Test for roots in four to six weeks by very lightly tugging on the base of the stem. Determine if the cutting feels "stuck" to the perlite, which indicates that roots have formed. Turn off the propagation mat after rooting.
10. Transplant the Mulberry
Transplant the mulberry into a 1-gallon nursery container filled with loamy soil six weeks after rooting. Grow it under sheltered conditions with regular irrigation for the rest of the year. Transplant it into a sunny bed in the spring after the last hard frost.
