Osmanthus cuttings have low propagation cost and early flowering, which is the main propagation method in cultivation.
Strictly speaking, osmanthus can be cut in all seasons, but due to different conditions, different times and methods are chosen.
Home potted plants and small yard plantings, generally cuttings in late spring.
Not according to the specific fixed time, see the new branches of the year semi-lignified and prune.
It is better to leave two to four budding points on one cutting, and leave two pairs of leaves to prevent nutrient consumption, and cut off half of the leaves.
Soak the pruned shoots in the rooting solution, usually for two to three hours.
Flower pots can be used for cuttings seedbeds, which can be in the ground, or seedling trays, and paper cups are recommended for family cuttings. Generally, a simple paper cup that has been drunk can be drilled with a hole in the bottom, placed on a tray in branches, or placed in impermeable foam blocks.
These can be found in used packaging materials, waste recycling. Then fill the paper cup with half a cup of river sand at the bottom, and the top half cup with the sawdust and soil mixture.
Soak the substrate in the paper cup with water mixed with zinc sulfate, and then cut the cinnamon branches soaked in the rooting solution into the cup.
Keep it moist for more than 20 days, see the new shoots of osmanthus grow, basically have taken root, you can pour some potassium dihydrogen phosphate water to increase nutrition and promote vigorous growth.
When the sprouts have grown to about three centimeters, the seedlings can be transplanted into pots.
When transplanting, you can tear the paper cup apart, no need to pry and dig, and ensure that the tender roots are not damaged.
It is almost a cup of a seedling, and there is no need to slow down the seedlings when planted in a pot, and they continue to grow.
This kind of cuttings is almost only the money of rooting solution and nutrient solution, within ten yuan is enough, but planting flowers is also a metaphysics, some people buy a special seedling pot, special cuttings with vermiculite, perlite, coconut peat and the like, cut cuttings are measured with a ruler, observe the growth at any time, and still do not produce a seedling.
Nursery ground planting is generally autumn and winter cuttings (Sichuan Pingba District), after the osmanthus mother blooms, rest for about a month, you can prepare cuttings.
Osmanthus generally sprouts two new shoots in spring, changes leaves in late spring and early summer, and sends new shoots once in autumn.
The cuttings used for autumn cuttings are more mature, and the effect of continuing to grow vigorously in the second year is better than that of spring cuttings.
The seedbed can be covered with a layer of carbon slag, peanut walnut shells and other permeable substances, and then spread sand and fine soil on top of it, and disinfect with dichlorethoxin or dixone.
In order to reduce the amount of weeding, pendimethalin can be sprayed once. Dry the seedbed for two days, and you can take cuttings of osmanthus branches soaked in rooting liquid.
After cuttings, when watering, root rot can be added. Finally, cover with film, and every other week, choose a sunny afternoon and water the seedlings.
When the sprouts grow together, first open the two ends of the film to refine the seedlings for a week, and then completely remove the film.
Now there are very few osmanthus seedlings that are propagated in large quantities and sold, and the cuttings in the nursery are basically used to select straight osmanthus strips.
Straight seedlings are used to weave into vases, torii, mushrooms, etc., to improve the ornamental value.
So, the straight seedlings are selected to make shapes, and the seedlings that are not straight and slippery?It's all thrown away.
If you are near these nurseries, you don't need to take cuttings to propagate seedlings, and you don't need to buy osmanthus seedlings, you can pick up those eliminated seedlings.
Although it is not easy to make shapes for eliminated seedlings, for family potted plants, the crooked seedlings grow out, and they are more charming.
If there is no osmanthus nursery nearby, you can only read more information and master the cuttings technology.
