What Is The Difference Between A Flowering Quince And A Fruiting Quince?
In this article, we are focusing on Fruiting Quince (Cydonia oblonga), but there is another type of quince shrub commonly known as a Japanese Flowering Quince (Chaenomeles japonica) prized for its vibrant flowers. It’s important not to get the two confused.
These two distinctly different plants have their own unique characteristics. Here are some of the key differences between the two:
Botanical Classification:
- Japanese Flowering Quince (Chaenomeles japonica): Belongs to the genus Chaenomeles and is a deciduous shrub native to Japan and China. The plant is primarily grown for its attractive ornamental flowers.
- Fruiting Quince (Cydonia oblonga): Belongs to the genus Cydonia and is a deciduous tree native to Southwest Asia. Unlike the Japanese flowering quince, it is grown for its fruit, known as quinces.
Growth Habit and Size:
- Japanese Flowering Quince: It is a low-growing, spreading shrub that typically reaches a height of 3 to 5 feet (1 to 1.5 meters) and has a similar spread.
- Fruiting Quince: It is a small to medium-sized tree that can grow to a height of 10 to 20 feet (3 to 6 meters) and has a more upright and tree-like growth habit.
Flowers and Fruits:
- Japanese Flowering Quince: It is prized for its vibrant and showy flowers that bloom in early spring. The flowers can be red, pink, orange, or white, depending on the cultivar.
- Fruiting Quince: While the fruiting quince also produces attractive flowers in spring, they are less showy than the flowering variety.
The true highlight is its pear-shaped, aromatic fruit. Quinces have a golden-yellow color when ripe with a pleasant fragrance and tart flavor.
Fruit Use:
- Japanese Flowering Quince: The fruit of this variety is not typically used for culinary purposes. Instead, it is primarily grown for ornamental purposes and as a pollinator for other fruiting plants.
- Fruiting Quince: The fruit is valued for its culinary applications. Quinces are used to make jams, jellies, preserves, pies, and other delicious desserts. They are prized for their high pectin content, which makes them excellent for preserving.
Cultural Significance:
- Japanese Flowering Quince: In Japanese culture, the flowering quince symbolizes love, affection, and courage. It is often used in floral arrangements and celebrated during spring festivals.
- Fruiting Quince: Fruiting quinces have historical and culinary significance in various cultures. They have been cultivated for thousands of years and are featured in traditional recipes and folk remedies.
What Time Of Year Do You Prune A Quince Tree?
Pruning a quince tree is an essential horticultural practice that helps maintain its health, shape, and productivity. The ideal time for pruning a quince tree depends on its age and growth stage.
General Pruning Principles for Quince Trees
Before delving into the timing, let’s establish some general principles for pruning quince trees:
- Always use sharp, clean tools to make precise cuts, minimizing the risk of damage and disease.
- Remove any dead, diseased, or damaged branches to improve overall tree health.
- Aim to create an open center structure in young quince trees to allow sunlight penetration and air circulation.
- Balance pruning to encourage fruiting wood and stimulate new growth.
- Avoid heavy pruning during winter, as this may lead to excessive vegetative growth at the expense of fruit production.
Quince Tree Age and Pruning
The timing of your pruning can vary based on the age of the quince tree.
Young Quince Trees (1-3 years old): Young trees require formative pruning to establish their shape and structure. The best time to do this is during late winter or early spring, just before the tree breaks dormancy.
This allows the tree to allocate resources efficiently during the growing season and develop a strong framework.
Mature Quince Trees (4+ years old): Once a quince tree reaches maturity, it should be pruned to maintain its shape and encourage fruiting wood.
For mature trees, the best time to prune is during late winter or early spring, before new growth emerges but after the risk of severe frost has passed.
In temperate climates, late February to early March is often the recommended period.
Climate Considerations
The timing of pruning can also be influenced by the climate in which the quince tree is growing:
- Temperate Climates: In regions with temperate climates, such as Northern Europe and North America, spring pruning should be done after the last frost. This allows the tree to heal its wounds quickly once the growing season starts.
- Mediterranean or Warm Climates: In areas with mild winters and hot summers, like Mediterranean regions, it’s better to prune in late winter or early spring.
- Cold Climates: In colder climates, it’s crucial to avoid pruning during the fall or late winter when temperatures can drop significantly. Pruning during these periods can lead to winter injury and frost damage. Wait until the weather warms up both day and night.
Remember that while general principles apply, local factors such as microclimates, soil conditions, and specific quince tree varieties should also be considered.
Always adapt pruning practices to the specific needs of your tree and consult local experts or horticulturalists for tailored advice.
How Do You Prune An Overgrown Quince Tree?
Pruning an overgrown quince requires careful planning and execution to rejuvenate the plant while maintaining its health and productivity.
Assessment and Preparation
Begin by assessing the quince to understand its overall health, structure, and the extent of overgrowth. Identify dead, diseased, and crossing branches that need to be removed.
Equip yourself with the right pruning tools, such as sharp pruning shears, loppers, and a pruning saw, to make clean cuts.
Always disinfect your cutting implements with a sterilizing product such as rubbing alcohol between cuts or at least between trees to reduce the chance of disease spread.
Timing
The best time to prune an overgrown quince tree is before the tree breaks dormancy in spring but after nighttime frosts have finished. This allows the tree to recover and direct energy towards new growth once the growing season starts.
Renewal Pruning
Overgrown quince trees often benefit from renewal pruning, a technique that involves removing old, unproductive wood to stimulate new growth and increase fruit production.
Identify and remove one-third of the oldest branches at the base of the tree. These branches are usually thicker and less productive.
Aim to maintain a balanced structure, keeping the main scaffold branches spaced evenly around the tree to allow sunlight penetration.
Thinning
Overcrowded branches can inhibit sunlight and air circulation, leading to reduced fruiting and increased disease susceptibility.
Selectively thin out branches that are crossing, rubbing, or growing towards the tree’s center. Aim to retain strong, outward-growing branches and remove weak or inward-growing ones.
Heading Back
To reduce the height and overall size of an overgrown quince tree or bush, use the heading back technique.
Identify branches that have grown too long or tall or that have become unmanageable and make pruning cuts just above outward-facing buds or lateral branches.
Try to avoid cutting into old wood as it may lead to slow or no regrowth.
Pruning Cuts
Make clean cuts at the appropriate locations to minimize damage and encourage healing.
For smaller branches, use sharp pruning shears, cutting just above a bud or lateral branch at a 45-degree angle.
For larger branches, use loppers or a pruning saw. Begin with an undercut to prevent bark from tearing, then make a final cut just outside the branch collar (swollen area where the branch meets the trunk).
Post-Pruning Care
After pruning, apply a balanced fertilizer to provide essential nutrients for new growth and recovery.
Mulch around the base of the tree to conserve moisture and suppress weed growth.
Regularly water the tree to support its recovery and growth.
The process of pruning an overgrown quince tree requires patience and expertise. If you’re uncertain or the tree is severely overgrown, consider consulting a certified arborist or horticultural expert for professional guidance.

Can You Cut Quince To The Ground?
Cutting a quince tree to the ground, also known as “renewal pruning,” is an extreme measure that involves cutting the tree back to its base.
While this approach can be risky, quince trees are resilient and can often tolerate renewal pruning if done under specific circumstances and with proper care.
By cutting the tree down to the ground, you remove all the old and unproductive wood, encouraging vigorous regrowth from the base.
The best time to perform renewal pruning on a quince tree is during late winter or early spring, just before the tree breaks dormancy, allowing the tree to utilize the energy stored in the roots to support new growth once the growing season begins.
While renewal pruning can be a drastic measure, there are specific circumstances under which it might be considered:
- Overgrowth – If a quince tree has become severely overgrown, with many old and unproductive branches, renewal pruning can help revitalize the tree and restore its productivity.
- Disease or Infestation – If the tree has suffered from recurring diseases or pest infestations that have damaged a significant portion of the branches, renewal pruning can remove the affected wood and potentially help the tree recover.
- Winter Damage or Dieback – In regions with harsh winters, quince trees can experience winter damage or dieback. In such cases, cutting the tree to the ground can remove the damaged parts and encourage fresh growth.
- Reviving Neglected Trees – For quince trees that have been neglected for an extended period, with poor pruning or no pruning at all, renewal pruning can provide a fresh start and encourage healthier growth.
Procedure for Renewal Pruning
Begin by assessing the tree’s overall health and structure to determine if renewal pruning is the best option.
- Use clean, sharp, sterile tools, such as a pruning saw or loppers, to make clean cuts.
- Cut all the main branches back to the base of the tree, leaving only a few inches above the ground.
- Remove any diseased, dead, or damaged wood completely.
- Apply a balanced fertilizer to the base of the tree after pruning to support new growth.
- Regularly water the tree to help it recover and promote new shoots.
Post-Pruning Care
After renewal pruning, the quince tree will undergo a period of vigorous regrowth. Provide adequate water and nutrients to support this process.
Consider applying a layer of mulch around the base of the tree to conserve moisture and control weeds.
Monitor the tree’s progress and remove any unwanted or weak shoots to encourage strong and well-spaced new branches.
Renewal pruning is a drastic measure and should only be considered when other pruning methods are not sufficient. There is always the risk that the tree might not survive.
How Do You Stop Quince From Spreading?
Controlling the spread of a quince tree helps to prevent it from encroaching on neighboring areas, such as other plants, structures, or property boundaries.
There are several methods to stop a quince from spreading:
Root Pruning
This involves cutting the lateral roots around the tree’s perimeter to limit its ability to send out new shoots and spread further.
Use a sharp spade or root pruning tool to sever the lateral roots at a distance of 3 to 4 feet from the trunk, creating a root barrier. Ensure that the barrier extends at least 18 inches deep to prevent regrowth from the cut roots.
The main risk when root pruning is that disease can enter the cut roots.
Regular Pruning and Maintenance
Proper pruning and maintenance play a crucial role in managing the spread of a quince tree.
Regularly prune the branches that extend beyond the desired boundaries, cutting them back to the main trunk or a lateral branch.
Remove any suckers (vigorous shoots arising from the tree’s base or roots) as soon as they appear to prevent further spread.
Installation of Physical Barriers
Physical barriers can help prevent quince trees from spreading into unwanted areas. Install materials like metal or plastic root barriers around the perimeter of the tree, going at least 18 inches deep to prevent root extension.
Consider using landscape edging, concrete curbs, or other non-porous barriers to limit the above-ground spread of the tree.
Chemical Methods
While chemical methods are generally not recommended due to their potential environmental impact, herbicides containing glyphosate or triclopyr can be applied to the foliage of suckers or unwanted shoots.
However, exercise extreme caution when using herbicides, as they may affect other plants and wildlife and if used incorrectly can also kill the entire tree.
If you opt for chemical control, carefully follow the manufacturer’s instructions and consider consulting with a professional to minimize negative consequences.
Mulching
Applying a thick layer of organic mulch (e.g., wood chips) around the base of the quince tree can suppress the growth of suckers and prevent spreading.
Make sure the mulch does not touch the trunk directly to avoid moisture buildup and potential bark rot.
Vigilance and Persistence
Regularly inspect the tree’s surroundings for new growth and take prompt action to control it.
How Tall Does A Quince Get?
Determining the exact height of a fruiting quince tree can be challenging, as it varies based on multiple factors, including the specific cultivar, growing conditions, and pruning practices.
Average Height
Quince trees are typically small to medium-sized fruit trees. On average, they can reach a height of 10 to 20 feet (3 to 6 meters) at maturity. However, the actual height may differ between individual trees and can be influenced by various factors.
Cultivar Variability
Different quince cultivars may have slightly different growth habits and mature at varying heights.
Some dwarf or semi-dwarf quince cultivars have been developed for smaller spaces and can be maintained at a lower height through proper pruning and training techniques.
Growing Conditions
The height of a quince tree is influenced by the specific growing conditions in which it is planted. Factors such as soil fertility, moisture availability, and sunlight exposure all impact the tree’s growth rate and overall size.
Quince trees planted in fertile, well-draining soil and provided with adequate water and sunlight are likely to grow taller compared to those in less optimal conditions.
Pruning Practices
Pruning plays a crucial role in shaping the size and structure of a quince tree.
Regular and appropriate pruning helps control the height and spread of the tree, especially if you wish to maintain it at a small size.
If left unpruned, quince trees may grow taller, but they can also become more open and sprawling.
The height of a quince tree is just one aspect of its growth habit. Besides height, factors like canopy shape, spread, and overall health contribute to the tree’s appearance and productivity.
Conclusion
Pruning a quince tree promotes tree health, shape, appearance, and fruit production. The timing and methods of pruning are essential considerations in ensuring the tree’s overall growth and productivity.
Formative pruning of young trees, 1-3 years old, is crucial to establish a strong framework. This involves shaping the tree by removing competing branches and creating an open center structure to allow sunlight penetration and air circulation.
Formative pruning is best performed during late winter or early spring, just before the tree breaks dormancy.
Maintenance pruning of mature trees, 4+ years old, is required for maintenance to maintain their shape and encourage fruiting wood. This includes removing dead, diseased, or damaged branches and thinning out overcrowded branches to enhance sunlight exposure and airflow.
Maintenance pruning is typically done during late winter or early spring before new growth emerges, but after the risk of severe frost has passed.
Renewal pruning of overgrown trees. This can be used to rejuvenate the tree and involves cutting the tree back to its base, and removing all old and unproductive wood to stimulate new growth and increase fruit production.
Renewal pruning should be undertaken during late winter or early spring, the same as maintenance pruning.
Following the appropriate pruning techniques at the right time can lead to a healthy, well-structured, and productive quince tree, providing bountiful harvests and enhancing the beauty of any garden or orchard.
