When to plant pear
- Transplant out: ~-6 weeks after last frost.
Companion plants for pear
Plant with: Chives, Garlic, Nasturtium.
Common pests & problems
Codling moth, pear psylla, fire blight: plant resistant varieties.
Feeding & fertilizer
N-P-K ratio: Balanced 5-5-5, avoid fresh manure
Organic options: Compost mulch every spring · Blood meal + bone meal before flowering · Kelp meal after harvest
When to feed: Once in spring, once after fruiting. Renovate strawberry beds every 3 yrs.
Watch for: Runner overload but few berries = too much N.
N = nitrogen (leaves), P = phosphorus (roots and flowers), K = potassium (fruit and disease resistance). How to read a fertilizer label →
Grower's tip
Pick pears firm and ripen in the fruit bowl: tree-ripened pears turn gritty.

Soil & water for pear
Soil & pH
5.8-6.5 (berries lower; apples/pears 6.0-7.0)
Deep loam with sharp drainage. Berries dislike heavy clay and wet feet.
Compost mulch each spring. For strawberries, renovate the bed every 3 years to keep yields up.
Watering
1-1.5 in / week; 2 in during fruit swell
Drip. Overhead watering causes berry rot and apple scab.
Small, seedy fruit = drought during ripening. Steady water two weeks before harvest fixes it.
Knowing when to harvest
- Pick FIRM. Tree-ripened pears turn gritty (stone cells develop).
- Fruit turns from lifting horizontally to lifting easily.
- Ripen indoors at 60-70°F for 5-10 days.
Storing & keeping
Cool (30-32°F), high humidity. 2-3 months for storage varieties. Ripen batches as needed.
What to expect
Per plant: 60-200 lb mature standard tree
Troubleshooting pear
Whole branch turns black, curled tip (shepherd's crook)
Likely cause: Fire blight
What to do: Cut 12 in below infection; sterilize pruners between cuts; plant resistant varieties.
Shoot tips blacken and curl into a hook shape
Likely cause: Fire blight, a bacterial infection entering through blossoms
What to do: Prune 8-12 in below the visible damage in dry dormant weather, disinfecting tools between cuts. Choose resistant cultivars where the disease is established.
Tree flowers well but sets almost no fruit
Likely cause: Most pears need a second compatible cultivar blooming at the same time
What to do: Plant a compatible pollinizer within about 50 ft, and note that Bartlett and Seckel will not pollinate each other.
Varieties worth growing
Bartlett
The classic; needs a pollinator.
Kieffer
Fire-blight-resistant heirloom for humid climates.
Harrow Sweet
Fire-blight-resistant modern variety.
Growing pear in containers
Genetic dwarf varieties only; usually poor.
Nutrition
Vitamin C, anthocyanins, ellagic acid (berries); pectin and quercetin (pome fruit).
Common questions
Why did my pear split without ripening?
Left on the tree too long. Pick firm; ripen at room temperature.
