How Do You Propagate Aralia Hispida?
Aralia Hispida can be propagated from seeds, cuttings, and division. Propagation from seeds is the most common method used to obtain new Aralia Hispida plants. Seeds need to be planted indoors 3 – 4 weeks before transplanting outside to germinate and grow into healthy plants.
You should place the seeds in a tray of moistened soil and cover them with a clear plastic bag. After seeds have germinated, you should remove the plastic bag and continue to water them until they begin to develop roots. Once they have developed roots, you can transplant them outside after the last frost of spring or early summer.
Aralia Hispida cuttings should be taken when plants are in their dormant period. Dig up clumps of old roots and lay them in a shallow depression in moist but well-drained soil.
Keep your cutting moist until it has rooted; then transplant it. You must keep the soil moist but not wet. The following are steps to follow when propagating Aralia Hispida:
Propagation from seeds;
- Fill a large container with seed-starting mix and plant 8 to 10 seeds. Water the seeds thoroughly with a small watering can.
- Cover the pot with clear plastic to retain moisture, place it in a warm location, and water as necessary to keep the soil moist but not soggy wet.
- When the seedlings emerge, remove the plastic cover and move them to brighter light. Once they are an inch tall, thin them out so that only 2 or 3 plants remain in each container.
- Continue to water lightly and keep the soil moist but not soggy wet.
Propagation from cuttings;
- Prepare a site for planting a cutting by digging a small depression in the soil that is 3 to 4 inches deep and contains no or very few rocks, dirt clods, or debris.
- Dig up clumps of old roots and lay them side-by-side with their tops just slightly above ground level in the hole you have prepared.
- Insert a small stick or pencil into the ground around the roots to hold them in place.
- Water the plants thoroughly with a small watering can; then cover the hole with a 2-inch layer of mulch or pebbles to help retain moisture and keep soil from splashing up on your new aralia. You should keep any cuttings moist until they have rooted and developed new leaves.
- When the cuttings begin to grow, remove the mulch and transplant the new plants into pots or plant them in your garden in well-drained soil; water as necessary to keep them moist.
Propagation from division;
- Dig up clumps of old roots and separate the new plants by cutting through the roots with clean pruning shears or digging them out of the soil with a small shovel.
- Replant each new plant in its container or in your garden and water as necessary to keep the soil moist but not soggy wet.
- Cut back each new plant when it has reached 4 inches in height. If you plan to divide several new plants, leave a 4-inch spacer between each plant.
- When the new plants have developed new leaves, cut them back to 4 inches in height and water.
- Water them thoroughly; then cover the hole with a 2-inch layer of mulch or pebbles to help retain moisture and keep soil from splashing up on your new aralia.
- Plant the new plants in your garden or pots when they have rooted and developed new leaves.
- Water is necessary to keep the soil moist but not soggy wet.
How Much Light Does Aralia Hispida Need?
Aralia Hispida prefers full sun, however partial shade to shade may suffice; however, the location should be sunny. It would respond differently to the one in complete sunlight. The shrub will thrive in a location that receives at least four to five hours of sunshine daily.
The optimal position for Aralia Hispida is in full sun, although the plant may withstand a small bit of mild shade later in the growing season, as autumn approaches. The amount of light required will depend on the variety, but most need some exposure to direct sun throughout their growing season.
During the winter months, you may want to place this plant in a sunny location indoors if temperatures are too low to allow it to bloom outdoors. This plant can tolerate shade but will not flower or grow well if it is placed too near a building or dense vegetation.
The sunlight will not be as potent, but it will still provide sufficient light throughout the cold season. If your Aralia Hispida plant is not growing well after transplanting then lack of sunlight might be the reason. Make sure that you are getting the necessary sunlight exposure for your plant and that it receives plenty of light during its growing season.
How Do You Overwinter Aralia Hispida?
To overwinter, Aralia Hispida can be potted or layered in a cold frame during the winter months. This can take place either indoors or outdoors. If you decide to overwinter it outside, ensure that it is sheltered from the wind and direct sun during the winter months.
When overwintering Aralia Hispida outdoors, you should provide a frost blanket under an overhang and keep the soil moist but not soggy wet.
To overwinter Aralia Hispida indoors, remove the leaves from the plant; prune back to 6 inches as far as it will grow, and lay them in the bottom of a wire or plastic pot with drainage holes. The pot should not be much larger than what the roots are wrapping around to keep moisture from escaping from the pot. The following are some of the ways to overwinter Aralia Hispida;
The best way to overwinter Aralia Hispida is to protect the plant from freezing winter weather by mulching or burying it. You can layer a 2-inch layer of mulch such as straw, leaves, peat, or pine needles in a cold frame; or you can plant it into a hole or trench about 4 inches deep.
After three cold months, the plant may be susceptible to freezing weather injury. When this happens, you should heave, lift, and store it indoors before the weather causes freeze damage.
Store in basement/garage:
Another way to overwinter Aralia Hispida is to store it in a basement or garage. You can leave the pot with its roots exposed to the air until it has completely frozen; then cover the pot with a 2-inch layer of mulch or straw to keep it from freezing. If you have direct sunlight exposure, you must protect it from frost.
Another way to overwinter Aralia Hispida is to bring it indoors during winter. Once the first frost has hit, you must dig up the roots and store them in a pot with drainage holes. You should keep the plant lightly moist but not soggy wet.
Another way to overwinter Aralia Hispida is to keep it in a cold frame. You can cover the cold frame with clear plastic sheeting and set it over a block of Styrofoam. Aralia Hispida can be kept outdoors during the summer months and brought indoors for winter storage. You should lay the leaves on the surface of the potting soil and the stems on top of branches that are lying on top of each other.
Another way to overwinter Aralia Hispida is to keep it in a cloche. You can set the cloche inside or outside, as long as there is indirect sunlight exposure and a frost blanket under the overhang. You should set the pot in well-drained potting soil and keep the plant lightly moist during autumn and winter.
How Do You Prune Aralia Hispida?
Aralia Hispida should be pruned once a year during spring and summer when it has reached a height of 6 inches. You can prune back the branches to within 4 inches of the tip. Make sure that you prune back both old wood and new wood.
Once you are finished pruning back, you should plant it in a pot or the ground, depending on whether you want to store it or overwinter it; then water as necessary. When pruning back Aralia Hispida, you should take into account the shape of the plant and its age.
If the plant is young, removing only a portion of the new growth is best, rather than pruning back too much. You can also prune Aralia Hispida using a saw; however, this can be difficult because each branch has its growth pattern. The following are steps to follow when pruning Aralia Hispida;
Cut back old wood:
When pruning Aralia Hispida, you should cut back the old wood branches to within 4 inches of the tip. Make sure that you prune back both old wood and new wood. Once you are finished pruning back, you should plant it in a pot or the ground, depending on whether you want to store it or overwinter it; then water as necessary.
Cut back tender branches:
Cut back weak branches to within 3 inches of the tip. Cut off any damaged branches or branches that are growing too close together. You can also cut back the stems on any branches that have died down.
Cut out damaged wood:
If you notice any damaged wood, cut it out and replace it with new shoots to replace the weakened branch. Also use a grafting knife to remove deadwood, leaf scars, or other damage.
Remove dead wood:
If you notice any dead wood, remove it. You should remove damaged wood that has not produced new growth for at least 2 years. Be sure that the cut is made close to the branch tip so that new growth will have a good chance of developing.
Trim back any sprigs:
Sprigs growing too close together can block the growth and cause the plant to become untidy. You can also prune off sprigs that are growing too close together.
Prune any broken or weak branches:
If the plant has grown too tall, you can prune back any broken or damaged branches to shape it. If the branch is weak, you can remove it and replace it with a new one. Again, you should cut close to the branch tip so that new growth will have a good chance of developing.
Suckers are branches that grow from the middle of the stem. You can remove these branches because they prevent light from reaching the rest of the plant, which hinders its growth. Remove suckers in early summer when they are young.
