To help your Green Giant arborvitae grow faster, there are a few key steps you can take. These evergreen trees are known for their rapid growth rate, but with a little extra care, you can encourage even more vigorous growth.
1. Soil Preparation: Start by preparing the soil before planting. Arborvitae prefer well-draining soil with a slightly acidic pH. If your soil is heavy clay or poorly drained, consider amending it with organic matter such as compost or peat moss. This will improve the soil’s texture and drainage, allowing the roots to grow more easily.
2. Planting Technique: When planting your Green Giant arborvitae, dig a hole that is wide and shallow rather than deep. This will encourage the roots to spread out horizontally, promoting faster growth. Make sure the planting hole is at least twice the width of the root ball but no deeper than the container it came in. Gently loosen the roots before placing the tree in the hole and backfill with soil, firming it gently around the roots.
3. Watering: Proper watering is crucial for the growth of any tree. Newly planted arborvitae should be watered deeply and regularly during their first growing season. This will help establish a strong root system. As the tree matures, it will become more drought-tolerant, but during dry spells, it’s still important to provide supplemental watering to encourage faster growth.
4. Fertilization: Applying a balanced fertilizer can give your Green Giant arborvitae an extra boost. Look for a slow-release or granular fertilizer with a balanced NPK ratio, such as 10-10-10. Apply the fertilizer in early or mid-spring before new growth starts. Follow the package instructions for the appropriate amount to use based on the size of your tree. Avoid over-fertilizing, as this can lead to excessive growth that is weak and susceptible to pests and diseases.
5. Pruning: Regular pruning can help shape your arborvitae and promote denser growth. However, pruning is not necessary for faster growth and should be done sparingly. If you do decide to prune, it’s best to do so in early spring before new growth begins. Remove any dead, damaged, or crossing branches, and lightly shape the tree as desired. Avoid heavy pruning, as this can stimulate excessive growth that may make the tree more susceptible to wind damage.
6. Mulching: Applying a layer of mulch around the base of your arborvitae can help conserve moisture, regulate soil temperature, and suppress weed growth. Use organic mulch, such as wood chips or bark, and spread it in a 2-3 inch layer, leaving a gap around the trunk to prevent moisture buildup.
7. Sunlight and Air Circulation: Green Giant arborvitae thrives in full sun to partial shade. Ensure that your tree is planted in a location that receives at least 6 hours of direct sunlight daily. Good air circulation is also important to prevent diseases, so avoid overcrowding your arborvitae with other plants or structures.
By following these steps, you can help your Green Giant arborvitae grow faster and establish a healthy, vibrant tree. Remember to be patient, as trees grow at their own pace, but with proper care, you should start to see noticeable growth each year.
