Select semi-lignified mature branches, 12-15 cm long, insert into the seedbed of sand and soil, and take root 20-25 days after insertion. Cutting can be carried out in spring or summer, and the rooting of semi-mature twigs is faster and grows better in the rainy season in June. It is necessary to set up a shed for shade at the initial stage after insertion to keep the seedbed moist. The growth rate of cutting seedlings is much faster than that of sowing seedlings. Euonymus tomentosa is usually cultivated into a spherical crown and then planted.
