Why Is My Yoshino Cherry Tree Not Blooming

Possible Causes

When a Yoshino cherry tree fails to bloom, it can be a sign of a variety of underlying issues. Many things can cause it, such as poor soil, erratic winter temperatures or inadequate moisture. It is also possible that the tree simply needs more time to reach maturity. Before assuming the worst, it’s important to conduct some basic troubleshooting.

First, check the age of the tree. If it’s less than three years old, it may be too young to bloom. It typically takes at least four to five years for a Yoshino cherry to generate blooms. Also, make sure you recently pruned away any dead wood growth.

Next, examine the soil where the tree is planted. As the University of Maryland Extension points out, cherry trees tend to do well in soil that is slightly acidic and has good drainage. Use a soil test strip to measure the pH levels and determine if your soil is properly balanced. If it doesn’t measure 6 to 6.5, you should consider Amending the soil or adding a layer of mulch.

It’s also possible that the tree isn’t getting enough water. Yoshino cherry trees prefer a consistently moist soil and often require supplemental watering. This can be especially necessary during dry or cold periods.

Finally, erratic winter temperatures can have a major impact. If a Yoshino cherry experiences a period of alternating freezing and thawing weather, it can disrupt the blooming cycle. This can cause the buds to die off and can result in a missing bloom the next spring.

Avoiding Winter Injury

To avoid winter damage, the University of Minnesota Extension recommends protecting the tree in the early stages. This involves carefully covering it during severe cold spells and surrounding it with plenty of insulation. For example, a thick layer of leaves, burlap or plastic sheeting can provide the insulation your tree needs.

It can also be helpful to conduct regular maintenance throughout the winter. Monitor the bark and look for potential signs of injury from cold or pests. If you notice any damage, you should prune it away immediately. In addition, cover the tree with a layer of mulch to help maintain water levels and prevent stress.

Finally, a good pruning job in December or January can make all the difference. Prune away any dead or damaged branches and shape the remaining ones as desired. To ensure maximum blooms, prune close to the trunk and ensure that the tree is short and bushy.

Fertilization and Pruning

Fertilization is key in fostering blooms on a yoshino cherry. Excess fertilizer can become acidic, resulting in nitrogen burn. Consider applying a slow-release fertilizer in the spring to avoid over-fertilizing. Apply 1.5 to 2 pounds (around 0.7 to 0.9 kg) of fertilizer around the tree and spread it evenly.

In addition to fertilizing, prune the tree for optimal growth during the dormant season. Start by removing any dead or diseased branches and cutting back the canopy of the tree to a more natural shape, if desired. Prune each branch where it meets the trunk without cutting into the living bark. Avoid cutting away too much foliage, as flowers tend to form on the current year’s shoots.

Regular pruning also helps to reduce competition and allow more light to reach the branches and buds. However, pruning must be handled carefully. Eager pruning can reduce the amount of buds and sap flow, resulting in fewer big blooms come springtime.

Adequate Nutrients and Sun Exposure

Your tree may also be missing out on necessary nutrients. Nitrogen, potassium, phosphorus, sulfur and magnesium are all important for healthy blooms. If you suspect your tree is missing out on one or more of these, you should consider adding a supplement. Likewise, inadequate sun exposure can prevent your tree from blooming. Yoshino cherry trees need at least six hours of direct sunlight per day to thrive and bloom come springtime.

Stake the tree if it is surrounded by turf or has weak root structure. This can provide the necessary additional support and help it get the most out of its available nutrients. Water the tree regularly and during extended periods of drought. Prune the tree to remove any branches competing for sunlight and consider using shade cloth or netting to block direct sunlight and dehydration.

Finally, a soil test can detect any mineral deficiencies and help you choose an appropriate fertilizer. Adding soil amendments and organic material such as compost can also help supply the necessary nutrients and improve drainage.

Environmental Factors

Environmental factors can also play a role. Yoshino cherries are more prone to disease if exposed to extreme temperatures, strong winds, intense sun and drought. If any of these conditions are present, consider using a fungicide to prevent infection and replace the soil with a nutrient-rich mix.

Another environmental factor to consider is frost. If your tree experiences a late frost, it can cause the blooms to die off before they have a chance to open. Use a frost blanket over the tree if temperatures drop below freezing. If the weather turns cold and rainy, consider installing a heating unit near the tree.

It also helps to provide your tree with adequate shelter. Wind can dry out the soil and cause stress, resulting in a lack of blooms. Installing a windbreak such as a fence or hedgerow can be helpful in this situation.

Pest and Animal Control

Pests and animals can also be a problem when it comes to Yoshino cherry trees. Even if you’re providing all the necessary nutrients and maintaining ideal growing conditions, pests can wreak havoc on the tree’s ability to bloom. Common issues include aphids, mites, scale insects and borers. Use organic pest control if possible to eliminate these threats and protect your tree from future infestations.

Likewise, animals can pose problems as well. Deer, rabbits and other animals can munch away at the foliage, resulting in stunted growth and poor blooms. To protect against trespassers, consider surrounding the tree with a fence or installing motion-activated sprinklers to scare away any potential threats.


As you can see, there are many things to consider when troubleshooting why a Yoshino cherry tree isn’t blooming. After conducting a thorough examination, you should be able to identify the cause and take the necessary actions to get your tree back on track. With proper care and attention, you should be able to enjoy a beautiful display of blooms come springtime.
