Pear Leaf Blister Mites (Leaf Spot)

A common problem with pears is the presence of small black spots on the leaves. These are called “pear leaf blisters” or simply “leaf spots”. They usually appear on one side of the tree only, but they may spread from branch to branch. Sometimes these spots are not very noticeable at all, while other times they can be quite severe and cause death within days if left untreated.

The reason why these spots appear is because some type of insect feeds on the pears and then excretes a substance which causes the spots. There are several types of insects that feed on pears, including aphids, mealybugs, scale insects and whiteflies. Some species are better at feeding than others so it’s best to get rid of them before they start spreading.

There are many different treatments available for treating leaf spot, but there is no single cure. You need to try out various methods until you find something that works well enough for your situation. Some of the most effective ways include:

1) Insecticidal Soap – Use a product like Miracle Gro® Fruit & Vegetable Spray to kill off any pests that might be causing the spots.

This will prevent future outbreaks and keep the tree healthy long term!

2) Biological Fungicides – Fungi can be used to stop infection from spreading.

Serenade® is a popular option because it has been proven to be very effective on fungal diseases like leaf spot.

3) Azalea Leaf Drop Treatment – This is more of a preventative treatment that helps to keep leaf spot from forming in the first place.

Use a product like Peters 20-20-20 Water Soluble Fertilizer to help strengthen the plant.

4) Antibiotic Treatment – If you want to play it safe, a good antibiotic can take care of the problem completely.

Use something like Spectrovert®.

5) Organic Treatments – There are many different “organic” methods that can be used against leaf spot.

Some of the most popular are milk, Epsom salt, baking soda and more.

Pear Tree Blossoms

When people think about pears they usually only think about the fruit. While the fruit is certainly the most popular part, the pear tree also has beautiful blossoms that are worth mentioning. The tree tends to bloom early in the year around March through May with white and green petals. The flowers only last one day before falling off the tree, but during that day they are able to attract bees and other insects that help with cross-pollination.

The blossoms tend to be small and not very flashy, but they’re very pretty. It’s this trait that makes them popular in flower arrangements for weddings and other formal events. The pear tree is known by several other names such as “bride’s pear”, “flowering pear”, “summer pear” and “wedding pear”.

How To Grow Pears

So now that you know everything there is to know about pears, you’re probably wondering what you need in order to grow them yourself. The answer is pretty simple actually as pears are one of the easier trees to grow. Most people have no problems at all growing them in their backyards. If you live in an apartment or somewhere without a yard you can grow them in large containers as well.

The first thing you need is the plant. You can either buy them at your local nursery or get them from a friend who has a tree. The goal is to get a one year old graft or a bench graft. These are the types of grafts that grow the fastest and produce fruit quicker than their non-grafted counterparts. It helps if you can identify the graft so whenever you’re buying a tree make sure you ask the clerk if it’s a grafted plant or not.

The next thing you need is a sunny location. Pears need at least 6 hours of direct sunlight in order to grow properly. If you don’t have an area that gets that much sun, you can use tree tents or large containers to help magnify the sun’s rays on the tree.

Fertilize the tree at least once a year using something like Miracle-Gro. You can also add bone meal and/or blood meal to the soil in order to provide even more nutrients.

Water the tree regularly making sure that the soil is always moist, but never wet. Overwatering is just as bad as Underwatering. The best way to know if you’re doing it right is by using a moisture meter which you can get at any garden center.

Pears can grow anywhere from 10 to 20 feet tall, but most home gardeners grow them vertically to save space. Use a strong trellis or pole to train the tree to grow upward.

Lastly you need to harvest your pears properly. Wait until the pear is ripe before picking it otherwise it won’t taste very good. To check if a pear is ripe simply pick it and give it a gentle squeeze. It should give slightly, but not be mushy. Another way to tell is by it’s color.

Ripe pears naturally begin to turn a yellowish-brown color.

After you’ve picked all the ripe pears you can start to wait for the next year’s crop. The rest is up to Mother Nature.

Final Note

And there you have it, everything you need to know about pears in easy to understand language with no legal mumbo jumbo included. Not only will you save yourself from potential lawsuits, you’ll also gain a new found respect for these delicious fruits and the wondrous things they can do for you.
