Why Fertilize Cherry Trees?

Cherry trees are heavy feeders and require regular fertilization to thrive. Fertilizing your cherry tree provides it with the essential nutrients it needs to:

• Produce abundant, flavorful fruit
• Promote lush, healthy foliage
• Enhance disease resistance
• Improve overall vigor and longevity

When to Fertilize Cherry Trees

The best time to fertilize cherry trees is:

• Early spring: Before the tree breaks dormancy and begins to leaf out
• Mid-summer: After the tree has fruited, but before new growth slows down
• Fall: To prepare the tree for winter and promote root development

Choosing the Right Fertilizer for Cherry Trees

The ideal fertilizer for cherry trees should be balanced and contain:

• Nitrogen (N): Promotes vegetative growth (leaves and stems)
• Phosphorus (P): Enhances root development, fruit set, and ripening
• Potassium (K): Improves cold tolerance, disease resistance, and fruit quality

Most experts recommend a fertilizer with an NPK ratio of 10-10-10 or similar.

How to Apply Cherry Tree Fertilizer

1. Prepare the Soil: Amend the soil around the tree with organic matter, such as compost or manure, to improve drainage and fertility.
2. Calculate the Fertilizer Amount: Determine the amount of fertilizer to apply based on the tree's age and size (see Cherry Tree Fertilizer Calculator below).
3. Broadcast the Fertilizer: Spread the calculated amount of fertilizer evenly around the drip line of the tree (the area where the outer foliage reaches).
4. Water Thoroughly: Irrigate the tree deeply after fertilizing to dissolve the nutrients and carry them to the roots.

Common Mistakes in Cherry Tree Fertilization

• Overfertilizing: Too much fertilizer can burn the roots or damage the tree.
• Using the Wrong Fertilizer: Selecting a fertilizer with an improper NPK ratio can lead to nutrient deficiencies or imbalances.
• Fertilizing at the Wrong Time: Fertilizing too late in the season can encourage soft, late-season growth that is susceptible to frost damage.
• Ignoring Organic Matter: Amending the soil with organic matter is crucial for maintaining soil health and promoting nutrient availability.

Frequently Asked Questions

Q: How often should I fertilize my cherry tree?
A: Fertilize twice a year, once in early spring and again in mid-summer.

Q: What are the signs of overfertilization?
A: Scorched leaves, stunted growth, and root damage.

Q: Can I use manure to fertilize my cherry tree?
A: Yes, manure is an excellent organic fertilizer, but it should be composted first to reduce the risk of disease.

Q: How do I choose a balanced fertilizer for my cherry tree?
A: Look for a fertilizer with an NPK ratio of 10-10-10 or similar.

Q: Is it okay to fertilize my cherry tree in the fall?
A: Yes, fall fertilization can help prepare the tree for winter and promote root growth.

Q: What are some common fertilizer mistakes to avoid?
A: Overfertilizing, using the wrong fertilizer, fertilizing at the wrong time, and ignoring organic matter.

Q: How can I tell if my cherry tree is deficient in a particular nutrient?
A: Yellowed leaves indicate nitrogen deficiency, purple leaves indicate phosphorus deficiency, and brown leaves indicate potassium deficiency.

Q: Is foliar feeding an effective way to fertilize cherry trees?
A: Yes, foliar feeding can be used as a supplemental method of fertilization, but it is not a substitute for soil fertilization.
