Green Tower® Boxwood

Green Tower Boxwoods are known for their upright and columnar growth habit, making them ideal for narrow spaces and formal garden settings. These boxwoods typically reach a mature height of around 7-9 feet, with a spread of 1 to 2 feet. However, with proper care and maintenance, they can sometimes grow slightly taller or wider. It's important to note that growth rates and ultimate size can vary depending on factors such as growing conditions, climate, and pruning practices. Regular pruning can help control the size and shape of the plants to fit the desired space in the landscape.

Green Tower Boxwoods are relatively slow-growing plants, especially when compared to other shrubs. On average, they typically grow at a rate of around 4 to 6 inches per year under optimal growing conditions. However, growth rates can vary depending on factors such as soil quality, sunlight exposure, moisture levels, and pruning frequency. Generally, boxwoods are known for their dense, compact growth habit, and while they may not grow quickly, they can eventually reach heights of 7 to 9 feet with a spread of 1 to 2 feet over several years. Regular maintenance, including proper watering, fertilization, and pruning, can help promote healthy growth and maintain the desired shape and size of the plants.

The best place to plant Green Tower Boxwoods is in locations that meet their sunlight, soil, and space requirements. Here are some considerations:

Sunlight: Green Tower Boxwoods thrive in partial to full sunlight. Select a planting location that receives at least 4 to 6 hours of direct sunlight per day. However, they can tolerate some shade, especially in hotter climates.

Soil: These boxwoods prefer well-draining, fertile soil with a pH level between 6.0 and 7.5. Avoid areas with heavy clay soil or poor drainage, as waterlogged conditions can lead to root rot. Amending the soil with organic matter, such as compost, can improve soil structure and fertility.

Space: Green Tower Boxwoods have a narrow, columnar growth habit, making them suitable for planting in tight spaces or as a vertical accent in the landscape. Ensure there is enough space for the mature size of the boxwood, typically reaching heights of 7 to 9 feet and widths of 1 to 2 feet.

Protection: While boxwoods are generally hardy, providing some protection from harsh winds and extreme weather conditions can help prevent foliage damage and maintain the plant's health.

Landscape Design: Consider the overall landscape design and placement of other plants when choosing a location for Green Tower Boxwoods. They work well as foundation plantings, in formal hedges, or as specimen plants in mixed borders or containers.

Accessibility: Plant Green Tower Boxwoods in areas where they can be easily accessed for maintenance tasks such as pruning, watering, and fertilizing.

By selecting a suitable planting location based on these factors, you can ensure the optimal growth and health of your Green Tower Boxwoods.

To plant Green Tower Boxwoods, follow these steps:

Selecting Location: Choose a planting location that receives partial to full sunlight. Ensure the soil is well-draining and fertile, with a pH level between 6.0 and 7.5. Avoid areas prone to waterlogging, as excessive moisture can lead to root rot.

Preparing the Soil: Loosen the soil in the planting area to a depth of at least 12 inches. Remove any weeds, rocks, or debris from the site. Incorporate organic matter such as compost or aged manure to improve soil fertility and drainage.

Digging the Hole: Dig a hole that is slightly wider and no deeper than the root ball of the boxwood. The hole should be twice the diameter of the root ball to allow for proper root expansion. Ensure the top of the root ball sits level with the surrounding soil surface.

Planting: Gently remove the boxwood from its container and inspect the roots. Loosen any encircling roots and spread them out in the planting hole. Position the boxwood in the center of the hole and backfill with the excavated soil, gently firming it around the roots as you go.

Watering: After planting, thoroughly water the boxwood to settle the soil and eliminate any air pockets around the roots. Provide additional water as needed to keep the soil consistently moist during the establishment period.

Mulching: Apply a layer of organic mulch, such as shredded bark or wood chips, around the base of the boxwood. Mulch helps retain soil moisture, suppresses weed growth, and regulates soil temperature. Keep the mulch a few inches away from the stem to prevent rot.

Maintenance: Monitor the newly planted boxwood regularly for signs of stress, such as wilting or yellowing leaves. Water deeply during dry periods, especially in the first year after planting. Avoid overwatering, as this can lead to root rot.

Pruning: While not immediately necessary after planting, regular pruning helps maintain the desired shape and size of the boxwood. Wait until the following spring to prune, as the plant needs time to establish its root system.

By following these planting guidelines, you can ensure a successful establishment and healthy growth of your Green Tower Boxwoods.

To care for Green Tower Boxwoods, follow these guidelines:

Sunlight: Plant your boxwoods in an area that receives partial to full sunlight. They prefer at least 4-6 hours of sunlight daily for optimal growth.

Soil: Ensure well-draining soil with good organic content. Boxwoods prefer slightly acidic to neutral soil pH (around 6.0 to 7.5).

Watering: Keep the soil consistently moist, especially during the first year after planting. Once established, boxwoods are relatively drought-tolerant but benefit from regular watering, particularly during hot, dry periods.

Mulching: Apply a layer of organic mulch around the base of the plants to retain moisture, suppress weeds, and regulate soil temperature. Keep the mulch a few inches away from the stem to prevent rot.

Fertilization: Feed boxwoods with a balanced fertilizer in early spring before new growth begins. Follow the manufacturer's instructions for application rates. Avoid fertilizing late in the growing season, as it may encourage tender growth that's susceptible to frost damage.

Pruning: Prune boxwoods in late winter or early spring to maintain their desired shape and size. Remove any dead, diseased, or damaged branches throughout the year. Regular pruning encourages dense growth and improves air circulation within the plant.

Pest and Disease Management: Monitor your boxwoods for signs of pests such as boxwood leafminers or diseases like boxwood blight. Treat any infestations or infections promptly with appropriate measures, including insecticidal soap or fungicides, as needed.

Winter Protection: In colder climates, provide winter protection by applying a layer of mulch around the base of the plants and wrapping them with burlap to shield them from harsh winter winds and temperature fluctuations.

Regular Inspection: Regularly inspect your boxwoods for any signs of stress, including yellowing leaves, wilting, or unusual discoloration. Address any issues promptly to maintain the health and vigor of your plants.

By following these care guidelines, you can ensure that your Green Tower Boxwoods thrive and remain healthy year-round.

To prune Green Tower Boxwoods, follow these steps:

Timing: The best time to prune boxwoods is in late winter or early spring before new growth begins. Avoid pruning during hot, dry periods or during the dormant winter months.

Tools: Use sharp, clean pruning shears or hedge trimmers to make precise cuts and avoid damaging the plant.

Shape: Determine the desired shape for your boxwood, whether it's a formal hedge, rounded shrub, or another form. Trim the outer edges first to create the desired outline, then work inward to shape the interior branches.

Maintenance pruning: Throughout the growing season, lightly trim any stray branches or shoots to maintain the desired shape and size. Regular pruning encourages bushier growth and keeps the plant looking neat and tidy.

Remove dead or damaged branches: Inspect the boxwood regularly and remove any dead, diseased, or damaged branches promptly to promote overall plant health.

Sanitation: After pruning, clean your tools with rubbing alcohol or a diluted bleach solution to prevent the spread of diseases between plants.

By following these pruning techniques, you can maintain the shape, size, and health of your Green Tower Boxwoods effectively.

When planting Green Tower Boxwoods, space them approximately 2 to 3 feet apart to allow for adequate growth and air circulation. This spacing will provide room for the plants to develop without overcrowding while still creating a dense and visually appealing hedge or border.

To water boxwoods you should aim to keep the soil consistently moist but not waterlogged, especially during the plant's establishment period. After planting, water deeply to saturate the root ball, and then monitor the moisture level regularly. In general, boxwoods prefer slightly moist soil, so water them when the top inch of soil feels dry to the touch. During hot and dry periods, you may need to water more frequently, possibly every 7-10 days, while reducing frequency during cooler or rainy periods. Avoid overwatering, as this can lead to root rot and other issues.

The best time to plant boxwoods like is in the early spring or fall. These seasons provide milder temperatures and typically more consistent moisture levels, which can help the plant establish its roots without the stress of extreme heat or cold. However, if you live in a region with mild winters, you can also plant boxwoods during the winter months. Avoid planting during the hottest part of summer, as the intense heat can stress newly planted shrubs.

Boxwoods can turn brown due to several reasons:

Winter Burn: Boxwoods are susceptible to winter burn, which occurs when the leaves lose moisture faster than they can absorb it during cold and windy conditions. This can result in browning of the foliage.

Watering Issues: Insufficient watering during hot and dry periods or overwatering, leading to root rot, can cause the leaves to turn brown.

Disease: Boxwoods are prone to fungal diseases such as boxwood blight and leaf spot, which can cause browning of the leaves.

Pests: Infestations by pests like boxwood leafminer or spider mites can damage the foliage, leading to browning.

Environmental Stress: Other environmental factors such as poor soil drainage, compacted soil, excessive fertilizer, or exposure to extreme temperatures or sunlight can stress the plant and result in browning of the leaves.

To address the issue, it's crucial to identify the underlying cause. Ensure the boxwood is planted in well-draining soil, receives adequate water, and is not exposed to harsh environmental conditions. Prune out any affected foliage, and consider applying fungicides or insecticides if diseases or pests are suspected. If the problem persists, consulting with a local horticulturist or extension service may provide further assistance tailored to your specific region and conditions.
