How many times have you or someone you know planted a fruit tree with very high hopes of harvesting fresh, juicy tree-ripe fruit? It is almost more times than you care to count. Growing fruits in your farm or garden can be both rewarding and troublesome. A common question that comes up is why trees fail to bear fruit or only have fruit every other year.

No farmer or gardener wants to only to be met with trees that grow and bloom but fail to produce fruit, you’re not alone. This frustrating issue has many potential causes, but the good news is that most of them are easy to fix.
How to Manage Soil to Maximize Your Harvest
1. Pollination Problems
You see, improper pollination is one of the most common reasons fruit trees fail to bear fruit. Many fruit trees are self-fruitful, meaning they can produce fruit by self-pollination. Others, however, are self-unfruitful and require cross-pollination with a different variety of the same species.
Correct it:
To prevent poor pollination, plant at least two compatible varieties of the same species within 50 feet of each other. Also, encourage the presence of pollinators, like bees, by planting pollinator-friendly flowers and avoiding pesticides that harm these vital insects. The more bees you have in your garden, the more likely your trees will successfully pollinate.
2. Inadequate Sunlight
Fruit trees are full-sun plants that need at least six to eight hours of direct sunlight per day to thrive. Insufficient sunlight can result in poor fruit production, even if the tree appears healthy.
Correct it:
Plant your fruit trees in locations where they will receive full sunlight throughout the day. Make sure to remove any nearby trees, plants, or structures that may block sunlight, especially as they mature. If your trees are planted in a shaded area, consider trimming or removing any obstacles that could hinder sunlight exposure.

3. Pruning Errors
We all know pruning is an important aspect for the good health of your fruit trees, but improper pruning can be the cause of no fruit production. Pruning too much or at the wrong time can remove flower buds that would eventually become fruit. Conversely, insufficient pruning can lead to poor fruiting and overcrowded branches.
Correct it
Prune your trees at the right time—late winter or early spring, before new growth begins. Only remove dead or diseased wood, and be careful not to over-prune. Ensure that you’re using the correct pruning method for your tree species. For example, apple and pear trees require different pruning techniques than peach trees, as they bloom on different types of wood.
4. Diseases
Bacterial and fungal diseases that take hold of your fruit tree can prevent you from harvesting the produce you're expecting. Fruit trees are also very susceptible to fire blight, powdery mildew and root rot, which can very badly affect the fruit productivity of a fruit tree. These diseases weaken the tree, preventing it from forming healthy fruit buds.
Correct it
Choose disease-resistant varieties of fruit trees and practice good garden hygiene. Remove fallen leaves and fruit from around the base of your trees, and ensure proper spacing between plants for adequate airflow. Apply fungicides or bactericides as needed, and destroy any infected plant parts to prevent the spread of disease.

5. Pests
While some insects, like borers, mites, and aphids, are beneficial to fruit trees, others, like aphids, can damage fruit, leaves, and flowers, which reduces the tree's ability to produce a crop.
Correct it
Employ integrated pest management (IPM) techniques, such as monitoring for pests, encouraging beneficial insects, and using physical barriers or traps to keep pests away. Determine the type of pests present and use neem oil, insecticidal soap, or other appropriate insecticides as necessary. Regularly trim affected branches and dispose of them properly to reduce pest populations.
6. Environmental Stress
Extreme temperatures, heavy rains, and prolonged droughts can all stress fruit trees, making it more difficult for them to thrive. Environmental stress can affect everything from flower formation to fruit development.
Correct it
Select fruit tree cultivars that are suited to your climate and growing zone. You live an area with some extreme weather patters? Use some mulch to protect the roots from temperature fluctuations and to keep them moist. To shield your trees from inclement weather, use covers or windbreaks. To encourage strong root growth, water your trees sparingly and deeply.
7. Over or Under-Fertilizing
Fertilization is vital to fruit production, but using the wrong type or too much fertilizer can stunt growth or encourage excessive vegetative growth at the expense of fruit production. On the other hand, under-fertilization can lead to nutrient deficiencies and poor fruit development.
Correct it
Your fruit tree has specific needs and these are best determined by carrying out soil tests, and you should therefore use a balanced fertilizer that helps fix the exact nutrients your soil is lacking. Be cautious of applying too much nitrogen, which promotes leaf growth but can inhibit fruit production. Use fertilizers higher in phosphorus and potassium to encourage better fruiting.
8. Watering Issues
Root rot can result from excessive watering, and drought stress can result from insufficient watering. The capacity of your fruit tree to bear fruit may be adversely affected by either of these circumstances. Watering must be done consistently.
Correct it
To keep the soil damp but not soggy, establish a regular watering schedule. Soaker hoses or drip irrigation systems are excellent choices for getting water straight to the roots. Mulch the tree's base to help retain moisture, control soil temperature, and lessen competition from weeds. To avoid waterlogging, make sure the tree is planted in soil that drains properly.

9. Excessive Tree Vigor
Overfertilization or over-pruning may be the cause of your tree's excessive growth and excessive wood production at the expense of fruit. If you fertilize your trees with too much nitrogen, they will grow too much and have less energy to produce fruit.
Correct it
Avoid overfertilizing the area surrounding the tree's root zone, especially if the nearby lawn is fertilized. Test the soil to determine the optimal fertilization rate. If your tree has been over-pruned, make more thinning cuts and fewer heading cuts to promote flower production.
10. Frost Damage
Fruit blossoms may be killed by late spring frosts, which would stop fruit from developing. Even if the frost happens after the flowers open, they are especially susceptible to freezing temperatures once they start to bloom.
Correct it
Fruit trees should be planted in parts of your garden that don't get frost, like next to a building or on a slightly raised spot. Steer clear of planting in low-lying locations where cold air pockets are likely to form. When a frost is expected, you can also cover flowering trees with garden fleece or cloth to protect them from the cold. During the day, you can remove the covers to let pollinators in.

11. Biennial Bearing
Some fruit trees can produce a large crop one year, but then produce little to nothing the following year. This is known as "biennial bearing." Excessive fruit production can drain a tree's energy reserves and reduce flower production the next year.
And this is how to correct it:
Early in the season, thin the tree's fruit to prevent overcrowding the branches. This process, which is sometimes called "fruit thinning," reduces the tree's stress and encourages consistent fruit production each year.
In Summary
You might have difficulty in identifying the major causes of low production of your fruit trees but armed with the proper information, giving attention to your fruit tree or orchard goes a long way in resolving the problem and reaping the benefits of a bountiful crop. Keep in mind that fruit trees require time to reach maturity, so exercise patience and continue to improve your strategy. If you persevere, you will soon be able to actually enjoy the results of your labor!
