Complete Growing Guide
Start preparing your planting site in late winter by working compost or well-aged manure into the soil. Laxton's Progress No. 1 thrives in soil with a pH between 6.0-7.0, so test and amend accordingly. This variety's compact 18-24 inch height makes it perfect for smaller gardens, but don't skip soil preparation — rich, loose soil directly translates to better pod production.
Direct sow seeds 2-4 weeks before your last frost date when soil temperature reaches 45°F. In zones 3-5, this typically means mid to late March; zones 6-8 can plant as early as February. Plant seeds 1-2 inches deep and 2-3 inches apart in rows spaced 12-18 inches apart. Unlike taller pea varieties, you can plant Laxton's Progress closer together for maximum yields in limited space.
While this dwarf variety doesn't require tall supports, provide low trellises or pea netting 2-3 feet high. The plants will lean and climb slightly, and support prevents pods from touching soil where they're prone to rot. Install supports at planting time to avoid disturbing roots later.
Fertilize lightly at planting with a balanced 10-10-10 fertilizer, then side-dress with compost when plants begin flowering. Avoid high-nitrogen fertilizers once established — peas fix their own nitrogen, and excess feeding promotes leafy growth at the expense of pod development. A common mistake is over-fertilizing these productive plants.
Maintain consistent soil moisture, especially during flowering and pod development. Water deeply once or twice weekly rather than frequent shallow watering. Mulch around plants with straw or shredded leaves to retain moisture and suppress weeds, keeping mulch 2 inches from plant stems.
In hot climates (zones 8-9), plant extra early and consider succession planting every 2 weeks through late winter. Laxton's Progress performs poorly in temperatures above 75°F, so timing is crucial for southern gardens. Northern gardeners can make succession plantings through early May for extended harvests.
Harvesting
Begin checking pods 60-65 days from planting when they reach 3-4 inches long and appear plump but still bright green. The pods should feel firm but yield slightly to gentle pressure — overly hard pods indicate the peas inside are past prime. Test a few pods by opening them; properly timed peas will be round, bright green, and sweet when eaten raw.
Harvest in early morning when pods are crisp and full of moisture. Use both hands when picking: hold the vine with one hand while gently pulling pods with the other to avoid damaging the plant. Laxton's Progress pods should snap off easily when ready. Check plants daily once harvesting begins, as pods can go from perfect to starchy within 2-3 days in warm weather.
Pick all ready pods even if you can't use them immediately — leaving mature pods on the plant signals it to stop producing new flowers. This variety will continue producing for 2-3 weeks with regular harvesting. The lower pods typically mature first, so work your way up the plant systematically.
Storage & Preservation
Fresh pods keep best unwashed in perforated plastic bags in the refrigerator for up to one week. For optimal sweetness, shell and use peas within 24 hours of harvesting, as their sugars convert to starch quickly even when refrigerated.
For freezing, shell peas and blanch in boiling water for 2 minutes, then immediately plunge into ice water. Drain thoroughly and freeze in portions suitable for your family size. Properly blanched and frozen Laxton's Progress peas maintain their sweet flavor for up to 8 months.
This variety also excels for drying into split peas. Allow pods to mature fully on the plant until they turn brown and rattle, then harvest and shell. Dry shelled peas on screens in a well-ventilated area for 2-3 weeks before storing in airtight containers. The sweet flavor of fresh Laxton's Progress translates beautifully into rich, flavorful split pea soup.
History & Origin
Laxton's Progress No. 1 was developed in the 1920s by Laxton Brothers, a renowned British seed company founded by Thomas Laxton in Stamford, Lincolnshire in 1877. The Laxton family revolutionized pea breeding during the early 20th century, creating numerous varieties that became garden staples on both sides of the Atlantic.
This particular variety was bred to combine the productivity of tall climbing peas with the convenience of compact growth, making it ideal for smaller British cottage gardens and the growing suburban American market. The 'Progress' name reflected the company's goal of advancing pea breeding technology while maintaining the classic English pea flavor.
During World War II, Laxton's Progress No. 1 gained popularity in victory gardens due to its reliable yields and compact size that maximized food production in limited space. The variety crossed the Atlantic and became established in American gardens by the 1930s, where it earned recognition for thriving in diverse climates while maintaining its distinctive sweet flavor and productivity that made it famous in English gardens.
Advantages
- +Exceptional productivity for such a compact plant, often yielding 6-8 pods per plant
- +No tall staking required — simple low supports or even growing unsupported works
- +Outstanding fresh eating quality with notably sweet, tender peas
- +Reliable germination and growth even in cool, wet spring conditions
- +Extended harvest period of 2-3 weeks with proper picking
- +Excellent for succession planting due to compact size and quick maturity
- +Superior freezing quality that retains sweetness better than many modern varieties
Considerations
- -Heat sensitive — struggles in temperatures above 75°F, limiting growing season
- -Shorter productive period compared to indeterminate climbing varieties
- -Pods must be harvested frequently or they become tough and starchy quickly
- -Lower total yield per square foot compared to tall climbing pea varieties
- -Susceptible to powdery mildew in humid conditions without good air circulation
