How to Grow Boston Pickling Cucumbers From Seed

Updated July 2026

Boston Pickling is the classic heirloom cucumber for crisp homemade pickles. The vines are heavy producers of small, blocky, medium-green fruit with lightly warted skin, ready in about 55 days. Pick the cucumbers young for jars of dill and bread-and-butter pickles, or eat a few fresh straight off the vine. It is a dependable, easy variety that keeps the canning pot busy all summer.

Quick start

Direct-sow seeds half an inch to one inch deep once the soil is warm, at least 65 to 70F, in full sun. Give the vines a trellis or open ground and thin plants to about 12 inches apart. Water steadily, one to two inches a week, to keep the fruit crisp and avoid bitterness. Start picking small, firm cucumbers at 2 to 4 inches from about 55 days, and harvest every day or two to keep the vines producing.

Best tip

Pick early and pick often for pickles. Boston Pickling fruit is best small, so harvest at 2 to 4 inches every day or two and never let a cucumber fatten and yellow, which signals the vine to quit. In hot, humid regions like the Southeast, water at the base and space plants for airflow to keep powdery mildew off, and in short-season areas like the northern Midwest start seeds indoors to get a head start on the 55-day crop.

Uses

Boston Pickling is bred for the pickle jar. Harvest the small, blocky fruit young for crisp dill pickles, bread-and-butter slices, and cornichons, or pack them whole into brine. The crunchy flesh also holds up in refrigerator pickles and quick vinegar salads, and the smallest cucumbers are good eaten fresh off the vine. One short row gives a family both fresh cucumbers and plenty of jars for the pantry.

Frequently asked questions

How many days does Boston Pickling cucumber take to grow?

Boston Pickling is a fast, early variety that reaches picking size in about 55 days from sowing. Because it is grown for small fruit, you start harvesting as soon as the cucumbers are 2 to 4 inches long, which comes even sooner than the full days-to-maturity figure suggests.

What size should I pick Boston Pickling cucumbers?

Pick them small and firm for the crispest pickles. Harvest at about 2 inches for cornichons and 3 to 5 inches for standard dill pickles. Check the vines every day or two at peak season, since the small blocky fruit sizes up quickly and picking often keeps the plant productive.

Is Boston Pickling only good for pickles?

No. While it is bred as a classic pickling cucumber, the crisp, blocky fruit is also good eaten fresh when picked young. Left a little longer it works in salads and refrigerator pickles, so a single planting gives you both fresh cucumbers and jars for the pantry.

How many Boston Pickling plants do I need for canning?

For a family that wants several jars of pickles, 3 to 6 healthy plants usually keep the canning pot busy through the summer. Boston Pickling is a heavy yielder, so even a short row produces plenty of small fruit if you keep it well watered and pick every couple of days.
