Planting Care

Planting & Care for Deciduous Shrub – Korean Spice Viburnum

Preparation
  • Prune in April and July. Trim shoots lightly in early spring.
  • Plant in March, and from May through November.
  • Korean Spice Viburnum needs at least half a day’s full sunshine to flourish.
    Shield large-flowering varieties from cold wind.
  • These shrubs prefer well-drained soil enriched with well-rotted organic matter several weeks before planting.
  • In light soils that parch quickly, mulch in spring with moisture-conserving, bulky organics to keep roots cool and active.
Opening Plant Material
  • Containers: Completely saturate all container plants by putting them in a larger water container until bubbling stops. Remove the plant, then dig a hole no deeper than the depth of the container, ensuring it’s wider on the sides by an additional 6” or more.
Planting Containers
  • Plant in March, and from May through November.
  • Slide the plant from the pot by tapping on the bottom of the pot.
  • With a shovel or knife, trim the bottom 2" off of the root ball for plants in plastic containers.
  • Rotate the plant to the proper position. Never lift or move plants by the tops.
    Place the root ball in the hole.
  • Notice where the base of the trunk flares out from the tree. This is called the root flare. This root flare should show when the tree is planted. If necessary, add soil under the ball so the root flare is exposed.
  • Place fertilizer packets into the bottom of the hole (if purchased). *Use Our Recommended Fertilizer.
  • Backfill the hole with soil, making sure the top of the root ball is visible and slightly higher than the soil around it.
  • Firm the soil around the plant. Water well to settle soil around the root ball.
Pruning - After Planting
  • Containers: Although it’s not essential after planting, light pruning can help shape a Korean Spice Viburnum. Doing so removes any broken branches from shipping or thins out a heavily branched plant to assist in the transplanting process and the appearance of your new planting.
Pruning - Through-out the Season
  • Prune in April and July. Trim shoots lightly in early spring.
Watering - After Planting
  • Plants typically take approximately 6 weeks to establish new roots in your soil. During this period, water plants as often as every 2-4 days at the start and at least a minimum of once per week.
  • Beyond the six-week establishment period, water once per week unless rain occurs.
  • Remember to check soil moisture by sticking your finger into the soil around 3”.
Watering - Through-out the Season
  • After the first season, plants should only be watered during extended periods without rain.
  • How do you know if your plants need water? The easiest way to tell is to touch the soil around the roots. If it is moist, there is no need to water. If it’s dry, give it a good soak with the hose end (no nozzle), watering the soil only, not the leaves.
  • Same as after planting, stick your finger into the soil around 3” to check soil moisture.

Frequently Asked Questions

What type of sun exposure is ideal for Korean Spice bush?

This bush thrives in full sun to partial shade. It requires at least half a day of full sunshine to flourish, although it should be protected from the harsh afternoon sun in very hot climates to prevent leaf scorch.

Are Korean Spice Viburnum (Viburnum carlesii) shrubs invasive?

Korean Spice Viburnum (Viburnum carlesii) shrubs are not invasive. These plants will form tidy thickets over time without bothering nearby plants. However, you may remove the suckers that form at the base of the plant. This can be done through pruning after flowering or mowing them down if you don’t want them to spread.

Why is my Korean Spice Viburnum (Viburnum carlesii) shrub’s leaves drying up?

A common cause of leaves drying up and branches dying back is drought stress. While this shrub is sometimes considered drought-resistant, that reputation only applies to well-established plants and relatively short drought periods, up to about four weeks.

Korean spice viburnum is only drought-tolerant to a certain extent. Beyond that point, the shrub will show signs of distress, such as dried-up and blackened leaves.

Homeowners often let ground covers and garden plants get quite thirsty, believing they will readily go dormant and quickly recover once it rains again. It's best to water your viburnum deeply and immediately when you notice the leaves starting to dry up and turn black.

What are the common problems when growing Korean Spice Viburnum (Viburnum carlesii)?

It's quite likely your Korean Spice Viburnum (Viburnum carlesii) is quite resilient against pests and diseases. However, you may encoutner issues with aphids causing leaf curl and Viburnum crown borers. Aphids can be dealt with by using organic neem oil. Afterward, prune the affected branch tips so the plant will recover. Your bush can also be affected by the Viburnum crown borer, an insect that bores into the lower stems, causing die-back. Maintaining the plant's health often prevents these insects from nesting. Applying pesticides to the lower 12 inches of the stems can eliminate the borers before they harm the shrub.

How do I protect my Korean Spice bush during winter?

Viburnums are very hardy shrubs that typically don't need winter protection from the cold if grown within their hardiness range. However, you may apply some level of protection to ensure they survive the harsh winter temperatures. As fall progresses, stop watering and fertilizing the plant. Avoid letting the shrub sit in damp conditions during winter, as this can lead to root rot. In some regions, a blanket of mulch over the root zone can be beneficial. Some growers in these areas also protect the shrub with a tent or burlap wrap to prevent winter burn. However, viburnums generally recover well from minor winter dieback.
