In summer, when the air humidity is relatively high, the cuttings of Rubber fig are generally suitable to survive from the end of June to the end of July.
The quality of cuttings directly affects the survival rate of cuttings, so it is necessary to choose suitable cuttings. Generally, the next year's thick branches with incomplete lignification on the surface are used as cuttings. This kind of branch has sufficient nutrition, easy rooting and strong disease resistance. On the contrary, it is difficult to survive if the lignified branches are selected.
One alcohol lamp and a number of sterilized jars (boiled with water) should be prepared, and the basin soil or wooden box can be used instead (the length of the wooden box depends on the number of spikes, and the depth is 15cm).
Before cutting, lay 5cm thick river sand in the container, then lay a layer of 10cm fine river sand, and pour enough water for standby.
Use plastic cloth and iron wire to make a cover larger than the container, and keep it moist after cutting.
Cut the robust branches of the Rubber fig into 12-15cm, and then burn them on the alcohol lamp (or burn them in boiling water). The white branches of the Rubber fig will not flow out.
Cut off the extra leaves on the branches and leave 2-3 leaves to avoid consuming the extra nutrients.
Insert the branches into the water, put them in a sunny place, spray water on the leaves 2-3 times a day, and change the water every 2-4 days. White roots can be produced in 8-10 days. (rooting by hydroponics can improve the survival rate of cuttings)
When the hydroponic root is 3-5cm long, insert the branch into the prepared basin soil, with a depth of 7-9cm, and keep the branch upright. Cover the cutting back cover with plastic cover to keep moisture. Spray clean water every morning and evening.
About half a month can grow a fixed heel, wipe off the extra buds, pour some fat water, and gradually transfer from the shade to the full light. Slowly will grow new leaves!
