Why these dates

Winthrop and Twisp's typical last spring frost is May 15. As a hardy perennial, this crop can go in about 6 weeks before that.

Inland Northwest. Higher, colder interior valleys. Cold springs and an earlier fall mean a shorter season; quick-maturing varieties pay off.

How to grow serviceberry in Winthrop and Twisp

  1. Pick a sunny spot with soil that drains well, and mix in an inch or two of compost.
  2. Plant serviceberry shrubs Apr 3 – May 29, 6 to 10 feet apart. Same depth as in the pot or nursery.
  3. Water through the first two summers. Prune out a few old stems in late winter to keep it productive, or train it to a single trunk as a small tree.
  4. Harvest: Pick in June or July when berries turn dark purple-blue and taste sweet. Net the shrub if you want to beat the birds.

Growing notes

What makes the difference in Northwest gardens, in plain language.

Where it grows wild

Western serviceberry, also called Saskatoon, grows on both sides of the Cascades, from dry eastern slopes and canyons to open woods and forest edges in the west. It's a shrub or small tree with clouds of white flowers in spring, sweet purple-blue fruit in early summer, and orange to red fall color.

Because it handles cold winters and dry summers, it's one of the few fruiting natives that does well almost anywhere in the region. Regent is a compact selection, and Smoky is known for sweet fruit.

Planting, pruning and pests

Serviceberry adapts to most well-drained soils in full sun to part shade, with more fruit in sun. Water through the first two summers. In late winter, remove a few of the oldest stems and any suckers you don't want, or train one strong stem as a small tree.

Rust, leaf spot and pear slug (small, slimy larvae that skeletonize leaves) show up in some years. Most are minor, and good airflow helps.

Harvest and wildlife value

Berries ripen in June or July and taste like a cross between a blueberry and an almond-scented cherry. Pick when they're dark purple-blue and sweet. They're delicious fresh, in pies or frozen.

Birds love them, which makes serviceberry a great wildlife plant and a frustrating fruit plant. Net the shrub just before the berries color if you want a full harvest. The spring flowers feed native bees early in the season.

Common questions

When is the last frost in Winthrop and Twisp, WA?

Typically May 15. In 9 years out of 10, frost is over by June 1. These are 1991–2020 NOAA climate normals for Winthrop.

Is it too late to plant serviceberry in Winthrop and Twisp?

The spring planting window runs through May 29. Potted plants can still go in later if you water them faithfully through their first summer.

How long until I can pick serviceberry?

First berries in two to four years. Pick in June or July when berries turn dark purple-blue and taste sweet. Net the shrub if you want to beat the birds.

What does serviceberry fruit taste like?

Sweet and mild, like a blueberry with a hint of almond from the small soft seeds. They're good fresh, baked into pies or made into jam.

Is serviceberry the same as Saskatoon?

Yes. Saskatoon is another common name for western serviceberry, Amelanchier alnifolia, the species native to the Northwest.

How do I keep birds from eating my serviceberries?

Cover the shrub with bird netting before the berries start to color. Smaller, compact varieties like Regent are easier to net.
