When to Fertilize Green Giant Arborvitae

Green Giant arborvitae (Thuja plicata ‘Green Giant’) is a fast-growing evergreen tree that is popular for use in landscaping. It is hardy in USDA zones 5-8 and can grow to be 50 feet tall and 20 feet wide. Green Giant arborvitae requires regular fertilization to maintain its healthy growth.

The best time to fertilize Green Giant arborvitae is in the spring, when the tree is actively growing. You can also fertilize the tree in the summer, but it is important to avoid fertilizing the tree during the fall or winter, as this can damage the roots.

When fertilizing Green Giant arborvitae, it is important to use a fertilizer that is specifically formulated for evergreen trees. The fertilizer should contain a balanced ratio of nitrogen, phosphorus, and potassium (N-P-K). The recommended rate of application is 1 pound of fertilizer per 100 square feet of area.

To apply the fertilizer, spread it evenly around the tree’s drip line. Be sure to water the fertilizer in well after applying it.

Spring fertilization

Spring is the best time to fertilize Green Giant arborvitae, as the tree is actively growing and will use the nutrients to produce new growth. The recommended rate of application is 1 pound of fertilizer per 100 square feet of area.

To apply the fertilizer, spread it evenly around the tree’s drip line. Be sure to water the fertilizer in well after applying it.

Summer fertilization

Summer is also a good time to fertilize Green Giant arborvitae, as the tree is still actively growing. However, it is important to avoid fertilizing the tree during the hottest part of the day, as this can damage the roots. The recommended rate of application is 1 pound of fertilizer per 100 square feet of area.

To apply the fertilizer, spread it evenly around the tree’s drip line. Be sure to water the fertilizer in well after applying it.

Fall fertilization

Fall is not the best time to fertilize Green Giant arborvitae, as the tree is preparing for winter and does not need as many nutrients. If you do fertilize the tree in the fall, use a light application of fertilizer and avoid fertilizing the tree within 6 weeks of the first frost.

Winter fertilization

Winter is not the best time to fertilize Green Giant arborvitae, as the tree is dormant and does not need any nutrients. If you do fertilize the tree in the winter, you risk damaging the roots.

How Much to Fertilize Green Giant Arborvitae

The amount of fertilizer to use depends on the size of the tree. The following table provides a general guide to the amount of fertilizer to use for trees of different sizes:

| Tree Size | Fertilizer Amount |
|—|—|
| Less than 10 feet tall | 1 pound per 100 square feet |
| 10-20 feet tall | 2 pounds per 100 square feet |
| 20-30 feet tall | 3 pounds per 100 square feet |
| 30-40 feet tall | 4 pounds per 100 square feet |
| 40-50 feet tall | 5 pounds per 100 square feet |

It is important to note that these are just general guidelines. The specific amount of fertilizer you need to use will depend on the soil conditions, the climate, and the health of the tree. If you are not sure how much fertilizer to use, it is best to consult with a qualified arborist.

The type of fertilizer to use depends on the soil pH

The type of fertilizer you use will also depend on the soil pH. Green Giant arborvitae prefers a soil pH of 6.0-7.0. If your soil pH is outside of this range, you will need to use a fertilizer that will help to adjust the pH.

For example, if your soil pH is too acidic, you will need to use a fertilizer that contains lime. If your soil pH is too alkaline, you will need to use a fertilizer that contains sulfur.

It is important to test the soil pH before you fertilize your Green Giant arborvitae. You can test the soil pH using a soil test kit.

Once you know the pH of your soil, you can choose a fertilizer that is appropriate for your tree.
