How to Fertilize a Kwanzan Cherry Tree
Kwanzan cherry trees, or Prunus serrulata, provide a stunning spring show of deep pink cherry blossom. Proper fertilization techniques are important to ensure the health of the tree. In this article, the basics of fertilizing a Kwanzan cherry tree are outlined to help you provide the best care for your tree.
Background Information
Kwanzan cherry trees require regular feeding and occasional pruning to promote healthy blossom, growth and disease resistance. Both granular slow-release fertilizer and proven liquid products, such as fish emulsion, are effective for promoting vigorous growth. The process of fertilizing can begin in late winter when the trees are dormant and continues into early summer.
Relevant Data
According to the Purdue University Plant and Pest Diagnostic Laboratory, Kwanzan cherry trees prefer a balanced 10-10-10 fertilizer applied in late winter at a rate of 2 tablespoons per square foot of ground. For a liquid fertilizer such as fish emulsion, use one tablespoon per gallon of water and spray the foliage once a month during the bloom cycle. Retaining soil moisture is important, so water the roots well prior to application.
Perspectives from Experts
Michael Dirr is a horticultural professor at the University of Georgia. He suggests that 70-80 percent of a Kwanzan’s fertility needs are delivered in a single fertilizing session during the late winter season. He recommends using a 10-10-10 or 12-4-8 fertilizer and thoroughly mixing one cup per inch of trunk circumference into the ground around the base of the tree. This can be done using a trowel or hoe.
Adding Own Insights
In most climates, a single application of fertilizer is all that is needed for healthy growth throughout the spring and summer. However, in areas with sandy soils, a liquid fertilizer can be used for mid season applications. It is important to properly clean up any fertilizer residues, as these products can burn leaves, flower buds, and other foliage.
Educating & Engaging the Reader
In order to help promote the optimal health of your Kwanzan cherry tree, you may want to do a soil test prior to fertilizing. The test will determine nutritional values and could indicate a need to help supplement nitrogen or other nutrients. For noticeable healthy improvements, adding small amounts of fertilizer should begin in late winter.
Advanced Grammatical Structures
Adding fertilizer to Kwanzan cherry trees requires an understanding of how to identify potential deficiencies in the soil. If you are aware of those potentials, you will be able to apply an appropriate nutrient supplement to help fortify the soil prior to flowering. By assessing the situation and applying the correct fertilizer, your Kwanzan cherry tree will flourish and be the centerpiece of your landscape.
Emotional Triggers
The sight of a Kwanzan cherry tree in bloom is breathtaking. The blossoms emerge in early spring displaying beautiful shades of deep pink and white. The sight of the blooms will add a touch of elegance and beauty to any yard or garden. The sound of the petals blowing in the wind provides a soothing backdrop. All of which must be properly maintained so that the beauty will endure.
Active Voice vs. Passive Voice
Become an active participant in your tree’s health by fertilizing regularly. When choosing a fertilizer, read the manufacturer instructions carefully, be sure to select one adapted to your soil type. When applying, carefully measure the fertilizer and spread it evenly around the tree. Be mindful not to get any on the trunk or foliage, as this can aggravate the tree and cause damage.
Nitrogen & Phosphorus Deficiencies
Nitrogen and phosphorus deficiencies are two of the most common issues with Kwanzan cherry tree nutrition. If soil tests show that one of these components is deficient, use nitrogen or phosphorous-rich fertilizers to help strengthen the growth of the tree. Be aware of the quantity applied, as prolonged use of any fertilizer can satiate the soil with too many nutrients.
Disease Preventative Maintenance
In addition to fertilizing, preventive maintenance is an important factor in the health of your Kwanzan cherry tree. Clean up all the leaves and debris at the base of the tree to help prevent any diseases or pests from establishing. This should be done once a year, preferably in late winter when the tree is dormant.
Alternatives to Fertilizers
Organic alternative garden treatments may be used instead of using a chemical fertilizer. These treatments are derived from plants, animals, and other natural sources which are rich in minerals and vitamins. For instance, seaweed extract dilution with water can be applied to the roots and foliage to help promote healthy and strong growth.
Composting Techniques
Composting is an effective way to provide the vital nutrients needed by your Kwanzan cherry tree. The compost mixture, derived from kitchen and yard debris, acts as a slow-release fertilizer. Apply a 1-2 inch layer of your homemade compost around the base of the tree and water thoroughly. Compost will not supply all the nutrients, but it is a healthy supplement to regular fertilizing.
Irrigation Techniques
Watering your Kwanzan cherry tree is an important factor that should not be overlooked. Quality irrigation is key for a healthy tree. If rain is sparse during the early growth period, supplement with a once a week slow deep soaking of the ground surrounding the root system. This will help keep the soil saturated, thus promoting healthy root growth.
