Key points
- This is because the pollen grains from a Bartlett pear tree are not compatible with the stigma (the female part of the flower) on the same tree.
- To produce fruit, you need a different pear variety that blooms at the same time and whose pollen is compatible with the Bartlett pear tree.
- It’s important to choose a pollinator that blooms at the same time as your Bartlett pear tree to ensure that the pollen is available for cross-pollination.
The Bartlett pear, with its juicy, sweet flesh and iconic shape, is a beloved fruit enjoyed by many. But did you know that a single Bartlett pear tree won’t produce fruit on its own? That’s right, these pear trees are self-incompatible, meaning they need a different variety of pear tree to cross-pollinate and produce fruit. If you’re wondering how to pollinate Bartlett pear trees, you’ve come to the right place. This guide will walk you through the process, from choosing the right pollinator to understanding the mechanics of pollination.
Understanding the Process: Why Cross-Pollination is Essential
Bartlett pear trees are self-incompatible, meaning that they cannot pollinate themselves. This is because the pollen grains from a Bartlett pear tree are not compatible with the stigma (the female part of the flower) on the same tree. To produce fruit, you need a different pear variety that blooms at the same time and whose pollen is compatible with the Bartlett pear tree.
Choosing the Right Pollinator: Finding the Perfect Match
The key to successful pollination is selecting the right pollinator for your Bartlett pear tree. Here are some popular and compatible options:
- Anjou: Anjou pears are known for their distinctive shape and crisp texture. They bloom around the same time as Bartlett pears, making them ideal pollinators.
- Bosc: Bosc pears have a distinctive brown, russeted skin and a sweet, spicy flavor. They also bloom in the same timeframe as Bartlett pears.
- Comice: Comice pears are known for their juicy, buttery texture and sweet flavor. They are a good choice for pollinators, although their bloom time may be slightly later than Bartlett pears.
Timing is Everything: Blooming Season Matters
The timing of the bloom period is crucial for successful pollination. Bartlett pear trees typically bloom in late spring, around the same time as other pear varieties. It’s important to choose a pollinator that blooms at the same time as your Bartlett pear tree to ensure that the pollen is available for cross-pollination.
The Role of Bees and Other Pollinators
Bees are the primary pollinators of pear trees. They are attracted to the flowers’ nectar and pollen, and as they move from flower to flower, they transfer pollen, facilitating cross-pollination. Other pollinators, such as butterflies and moths, can also contribute to the process.
Planting Your Pollinator: Distance is Key
When planting your pollinator tree, it’s important to consider the distance between the two trees. Ideally, the pollinator should be planted within 50 feet of the Bartlett pear tree. This proximity ensures that the bees and other pollinators can easily move between the trees, facilitating cross-pollination.
Hand Pollination: A Manual Approach
In situations where natural pollination is limited, you can manually pollinate your Bartlett pear tree. This involves collecting pollen from the pollinator tree and transferring it to the stigma of the Bartlett pear flowers. This method is most effective when done during the early morning hours, as the pollen is freshest at this time.
Observing Your Tree: Signs of Successful Pollination
After pollination, you will start to see signs of fruit development on your Bartlett pear tree. The tiny, green fruit will gradually grow in size and shape as they mature. If you see fruit developing, it’s a good indication that pollination was successful.
Harvest Time: Enjoying the Fruits of Your Labor
The time it takes for Bartlett pears to ripen depends on the climate and growing conditions. Typically, they are ready to harvest in late summer or early fall. When the pears are ripe, they will have a soft texture and a sweet, juicy flavor.
Beyond Pollination: Caring for Your Pear Tree
Pollination is just one part of the process of growing healthy and productive pear trees. Here are some other important care tips:
- Pruning: Regular pruning helps to maintain the shape of your pear tree and promote healthy fruit production.
- Watering: Pear trees need consistent watering, especially during dry periods.
- Fertilizing: Fertilizing your pear tree with a balanced fertilizer will provide the nutrients it needs for healthy growth and fruit production.
- Pest and Disease Control: Be vigilant about monitoring your pear tree for pests and diseases. Early detection and treatment are crucial for preventing serious problems.
The Sweet Reward: Enjoying Your Homegrown Pears
By following these steps, you can successfully pollinate your Bartlett pear tree and enjoy the sweet reward of homegrown pears. Remember, patience is key; it takes time for the fruit to develop and ripen. But with a little effort and care, you’ll be able to savor the delicious fruits of your labor.
What You Need to Know
Q: What if I only have one Bartlett pear tree?
A: If you only have one Bartlett pear tree, you won’t be able to produce fruit. You’ll need to plant a compatible pollinator variety to ensure successful pollination.
Q: Can I use a different pear variety as a pollinator?
A: While many pear varieties are compatible with Bartlett pears, it’s important to choose a variety that blooms at the same time. You can check with your local nursery or extension office for recommendations.
Q: How do I know if my pear tree is being pollinated?
A: You can tell if your pear tree is being pollinated by observing the flowers. After pollination, the flowers will start to wilt and fall off, and you will see tiny, green fruit developing.
Q: What if my pear tree isn‘t producing fruit?
A: There are several reasons why a pear tree might not be producing fruit. These include insufficient pollination, poor growing conditions, or pest and disease problems. Contact your local extension office for help diagnosing the problem.
Q: How long does it take for a pear tree to start producing fruit?
A: Pear trees typically start producing fruit 3-5 years after planting. However, some varieties may take longer to produce fruit.
