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: Base feeding on a soil test and on how much new growth the plant made last year.
Watch for: Lots of leafy growth but little fruit = too much nitrogen.
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
6.0-7.0 for most; confirm with a soil test
Deep, well-drained soil. Standing water around the roots causes root and crown rot.
Test soil before planting and correct pH then. Mulch with compost each spring, kept a few inches off the stem or trunk.
Watering
1-1.5 in / week; 2 in during fruit swell
Drip or soaker at the root zone. Keeping leaves and fruit dry lowers fungal disease.
Check soil 6 in down; water when it is dry there. Drought while fruit is sizing gives small fruit.
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 the space
Not every name in a seed catalog. These are the ones growers order again, with what each one is actually good at and what it asks of you.
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.

Common questions
Why did my pear split without ripening?
Left on the tree too long. Pick firm; ripen at room temperature.
