Shrub Plants: How to Choose and Plant Them Correctly

Key Takeaways

• Select shrubs based on your USDA hardiness zone, sunlight, mature height, soil conditions, and available space.
• Planting in fall and early spring is best because moderate temperatures let roots establish before the stress of summer weather arrives.
• It is just as important to plant the correct shrub as to plant it correctly.

Shrubs can do much more than fill empty spaces in a yard. They can create privacy, define property lines, frame entryways, support pollinators, provide seasonal color, and add structure that remains attractive for years. The right shrub plants can also solve practical landscaping problems, from screening an outdoor sitting area to stabilizing a sloped section of the yard.

But planting a shrub solely based on its appearance could lead to serious problems later on. The shrub will either become too big for its location, have inadequate sun exposure, or fail to survive through the winter.

Understanding your site and planting at the right time makes a major difference. These choices help prevent costly replacements later, too. Whether you want evergreen screening, colorful blooms, or a low-maintenance foundation planting, this guide explains what to consider before bringing shrubs into your landscape.

How to Choose the Right Shrubs for Your Yard

Begin by assessing the location where you intend to grow the plant instead of choosing the plant first. Observe the number of hours of direct sun exposure that the spot has, the nature of drainage in the soil, and the space that the shrub will occupy when fully grown.

Another very crucial point in selecting plants is your zone according to the USDA, especially if the zone experiences cold climatic conditions. Take note of the shrub's height and width after growing rather than looking at the height of the shrub as seen in the pot in the nursery.

Maintenance is another factor you may wish to look at, as some shrubs require constant pruning while others do not.

Types of Shrub Plants to Consider

Two primary types of shrubs are evergreen shrubs that are known for their foliage during all seasons and flowering shrubs that bloom and add beauty to a garden during particular seasons. Your decision should be based on your preferences and the conditions that you have.

1. Boxwood

Boxwood is an evergreen shrub that can be used as a border and decoration as well. It keeps its green leaves during all seasons, and boxwood shrubs can be shaped differently. You can choose those that are suitable for your space and conditions.

2. Hydrangea

Hydrangea flowers are big flowering shrubs that come in white, pink, blue, and purple colors. They can add much beauty during a particular season in your garden and can also be used as foundation plantings and focal points for landscaping. There are different types of hydrangea flowers requiring different conditions.

3. Azalea

Azalea is a type of flowering plant that can make the garden look colorful during its blooming period. There are a number of flower colors and sizes available in azaleas, which makes it useful as a border plant or a woodland garden plant.

4. Inkberry

The Inkberry is another evergreen shrub that could give year-round structure and dense foliage. It can be grown as a hedge, border, and naturalized garden plant and can tolerate wet soil better than most evergreen shrubs. The plant’s compact nature also means that it can be used where a softer screen is required.

5. Spirea

Spirea is an effective flowering shrub with clusters of flowers and is quite easy to maintain. Depending on the variety that you choose, spirea can function well in borders, mass plantings, or as a low hedge. You should know the variety’s mature height and its pruning requirements.

How to Plant Shrubs

Knowledge of proper shrub planting ensures healthy roots and minimizes transplanting stress. These are basic guidelines:

• Site preparation: Clear the planting area of any grass, weeds, rocks, and competing roots. Do not create an isolated hole surrounded by compacted soil.
• Not too deep but wide: The hole where the plant is to be planted should be wide enough so that its roots come into contact with the loosened soil around the plant hole. 
• Correct height: Once you put the shrub in the hole, its root ball should be even or slightly above the soil level. Covering the root flare with soil is not advisable.
• Backfilling: Backfill the plant hole with the excavated soil; add only the recommended soil amendment for the specific shrub when testing determines that this step is needed.
• Watering: Water the planted shrub well.
• Mulching: Place a couple of inches of organic mulch around the plant, keeping a few inches of space between the mulch and the trunk/stems.
• Fertilization: Do not fertilize the plant excessively unless soil tests or recommendations of particular species of shrubs indicate such need. The priority is the contact of roots with soil, sufficient moisture, and good drainage.

When to Plant Shrubs

The timing of shrub planting is determined by climate, soil conditions, and the shrub. Early spring is a good time once the soil can be worked, but before the high temperatures of summer.

Another suitable time of the year is fall. Lower temperatures will minimize the stress of the shrubs while the soil stays warm enough for root growth. It is better to plant a few weeks before the ground freezes.

It is better not to plant shrubs during times of extreme temperature changes, drought, frozen soil, and saturated soil. Shrubs require moisture; therefore, it is better to plant them at a time when they can be watered.

Can You Plant Shrubs in the Fall?

Autumn is considered one of the best seasons for planting woody shrubs since there is relatively less evaporation due to cooler temperatures and the soil is still warm enough for root growth.

However, the time of planting is crucial. Planting must not be delayed until the soil is frozen or the climate is quite cold in that area. In regions where autumn lasts only a short time, spring would be better for planting. Shrubs planted in fall should be well-watered until the ground freezes.

Spacing and Placement Matter

One common mistake when planting shrubs is putting them too close together. Use the mature plant width stated on the plant tag for spacing rather than the pot size.

If it is a hedge, closer spacing will mean faster growth of the screen, but overcrowding will lead to more competition for sunlight, water, and nutrients and reduced airflow. For individual foundation shrubs, there should be enough space so that the branches do not continuously touch the walls, windows, sidewalks, or utility equipment.

Sight lines should also be considered. Do not plant tall shrubs in places where visibility will be compromised at driveways, intersections, and entrances.

Watering and Early Care

New shrubs need plenty of water as their roots grow throughout the soil. You should water the plants thoroughly so they receive enough moisture, then check the soil moisture content rather than following a rigid schedule.

Watering depends upon the temperature, rainfall, soil type, size of the plant, and whether the plants have been grown in containers. The sandy soil dries out faster than clay soil, which holds moisture for a long time.

Ensure that the mulch stays put without piling up at the base of the plant stems. Beware of any signs of wilting, yellowing leaves, excessively dry soil, or pooling water.

Pruning and Long-Term Maintenance

Avoid any aggressive pruning right away after planting unless there are broken branches that need to be removed. The shrub will need all its leaves to manufacture energy, as it establishes itself within the root system.

After establishing itself, the pruning process should be done according to the nature of growth and flowering of the shrub. Begin by removing all dead, injured, or crossing branches. If it is a flowering shrub, identify whether it flowers from the old or new wood.

It may also pay to inspect your shrub now and then, as you can identify pests, fungal infections, poor drainage, and other signs of stress.

Conclusion

Shrub plants can offer many benefits in a garden, such as privacy, good structure, blooms, wildlife support, and seasonal interest, when used correctly. The key is to select shrubs that are right for your site based on their natural growth habits, environment, and requirements. Pick a good time of year to plant, allow proper root growth space, water regularly, and apply an appropriate mulch layer. Shrubs selected properly and established properly can become the most reliable garden elements.

FAQs

What are the proper soil requirements for new shrub plantings?

Shrubs require soil conditions that are conducive to drainage but can retain moisture to promote root development. The first thing to do is to assess how the soil responds to rainwater; if it pools, then the drainage must improve before fertilizing the soil.

What distance should be maintained from the house?

This would depend on the mature size of the shrub itself. You need to give enough distance so that its branches can grow freely without touching the sides of your home or impeding any kind of maintenance work.

Is it necessary to fertilize the shrubs in their first year?

The newly planted shrubs usually don't require any fertilizing as long as they are planted in fairly healthy soil. Over-fertilization will cause growth of the top part before the roots become well-established. Soil testing will help determine the need for fertilizers.

How often should I water the shrubs after planting?

It depends on climate conditions, soil, size of the plants, and type of shrubs. You should check the soil in the root ball area and water them whenever the soil starts drying out.

Which are some low-maintenance shrubs that can be planted in a landscape?

There are numerous varieties that can be considered low-maintenance, depending on the location and climate. However, the following are generally regarded as low-maintenance shrubs.
