Can the tall crape myrtle in the green belt germinate after being cut short?

I transplanted with soil, but because the soil ball was too big, the roots outside were cut off. Now, after spraying water, the stem is wrapped with transparent plastic film, and the top of the stem is sealed with wax to expose the film. I don't know if this will work. The temperature is above 35 degrees during this time. I put it on the inner balcony and I can't get the sun. View original post >>
