Green beans are a popular vegetable to grow in home gardens across Pennsylvania With the right timing on planting, you can enjoy a bountiful harvest of crisp, fresh green beans throughout the summer. This guide will outline the optimal planting window for green beans in Pennsylvania’s growing zones
Overview of Planting Green Beans in Pennsylvania
-
Green beans require warm soil temperatures, usually around 50-80°F to germinate and grow properly. They are susceptible to frost damage.
-
In most regions of Pennsylvania, the last spring frost occurs between mid-April and mid-May. The first fall frost arrives between late September and late October.
-
To maximize growth and production, green beans should be planted after the final frost but with enough warm growing season left for the plants to mature fully.
When to Plant Green Beans
-
South and Southeast PA (Zone 6b): Plant beans in mid to late May after the soil has warmed thoroughly. This allows time to harvest before first fall frost.
-
Central and Northeast PA (Zone 5b): Wait to plant beans in early to mid June once the danger of frost has passed.
-
Western and North Central PA (Zone 5a): Delay planting beans until early to mid June. The shorter growing season means quick-maturing bush bean varieties are best.
-
Higher elevations and valleys: Hold off planting beans until early June or even early July due to colder microclimates. Focus on fast-maturing bush beans.
Tips for Planting Green Beans
-
Check local frost dates and soil temperatures before planting. When overnight lows stay above 50°F, it’s safe to plant.
-
Sow seeds 1-2 inches deep and 2-4 inches apart in rows 18-36 inches apart. Beans need full sun (at least 6 hours).
-
For continuous harvests, make small, weekly successional plantings every 1-2 weeks from late spring through midsummer.
With the right timing, you can enjoy a plentiful green bean crop in your Pennsylvania garden. Pay close attention to planting dates for your specific region and garden conditions for the best results.
Planting seeds at the ideal time boosts the success of your garden and lets you enjoy the fruits of your labor as early as possible.
In Glenside, planting season is coming up quickly. But if you want a healthy garden this year, you need to do some planning before you can start digging in the dirt again. How to Plant Spring Seeds: This guide will show you which seeds to plant and when to plant them, whether you start them indoors or in your garden!
Part 1: Cool Season Vegetables to Seed Outside
Cool-season crops thrive in the milder temperatures of spring and fall. They can handle different levels of frost and can be planted before Glenside’s last frost date, which is usually between April 15 and 30. Here’s a list of some of Pennsylvania’s most popular cool-season veggies and the best times to seed them:
If you can work the soil, which should be around the middle of March, you can plant arugula outside as soon as it’s ready for salad. With its peppery flavor and tender leaves, arugula is a favorite for fresh salads and sandwiches.
Broccoli is a hardy cool-season vegetable that can be planted outside as soon as the ground is workable. However, some gardeners like to start their plants indoors and move them outside when the risk of frost has passed. When you start seedlings outside in the early spring, they grow more slowly at first, but this way, they grow faster faster.
Beets can be planted outdoors in March as soon as the soil is adequately thawed. Their sweet, earthy flavor makes them perfect for roasting, pickling, and adding to salads.
Bok choy is a fast-growing Asian green that can be planted outdoors once the soil is workable. With its mild flavor and crunchy texture, bok choy is perfect for stir-fries and salads.
Brussels sprouts are absolutely packed with vitamins and minerals. They grow best when planted in early spring, typically early to mid-April.
Since cabbage grows best in cool weather, you can plant it outside as soon as the ground can be worked, which is usually around the middle of March. Featuring a crisp texture and mild flavor, cabbage is perfect for coleslaw, sauerkraut, and cooked dishes.
Carrots are root vegetables that can be planted as soon as the ground is workable. But for their roots to grow, the soil can’t be too wet or packed down, so make sure you wait until it’s dry and loose.
People love cauliflower, which is a cabbage family plant that can handle light frost. However, make sure there is no chance of deep frost before planting. Mid- to late-April is usually the best time for seeding this cool-season crop.
Celery can be seeded outside in mid to late April. With its crisp texture and mild flavor, it’s perfect for salads, soups, and snacks.
Collards are ready to be directly sown in your garden around mid-March to early April. They’re renowned for their rich flavor, tender texture, and high levels of vitamins and minerals.
Kale is a cold-hardy vegetable that can be planted outdoors as soon as the soil is ready. Packed with essential nutrients and offering great flexibility in recipes, kale is an indispensable asset to any garden.
Lettuce thrives in cooler temperatures and can be planted outdoors in mid-March. With its rapid growth and variety of leaf shapes and colors, lettuce is a versatile addition!.
Mustard greens are a spicy green that can be planted outdoors as soon as the soil allows. Mustard greens, with their peppery flavor and easy-growing nature, add an early-season kick to salads and cooked dishes.
Onions are a cool-season crop that can be seeded outside as soon as the ground is workable. Prized for their intense flavor and culinary versatility, onions are a staple in many savory dishes.
Peas are a cool-season crop that can handle frost. They should be planted as soon as the ground can be worked, which is usually in mid-March to early April. People love these sweet and tender beans as a fresh snack and to add a fresh pop to salads and stir-fries.
Potatoes are another cool-season crop that can be planted as early as mid-March. They are perfect for roasting, mashing, and frying. Like carrots, they need loose soil for rooting, so make sure the ground has dried before planting.
Radishes are one of the first vegetables you can sow directly in the ground. These root vegetables grow quickly and add a zesty crunch to salads. They also get ready quickly, which is great for gardeners who don’t like to wait.
If the ground has thawed and is dry enough to work, you can plant spinach outside after the frost has passed. Packed with vitamins and minerals, spinach is a nutritious addition to salads, smoothies, and cooked dishes.
Swiss chard is a bright and healthy green that can be planted outside as soon as the ground can be worked, which is usually around the middle of March.
Turnips are a valuable cool-season crop that doesn’t get as much attention. They can be planted outside as soon as the ground is ready. With their sweet and earthy flavor, turnips are perfect for roasting, steaming, and mashing.

How warm to plant green beans?
Can you plant green bean seeds indoors?
Don’t plant too early, as cold, moist soil will delay germination and could cause the seeds to rot. Tip: To get a head start on planting, place black plastic or landscaping fabric over your garden beds to warm the soil prior to sowing seeds. Do not start green bean seeds indoors. Due to their fragile roots, they may not survive transplanting.
How do you pick green beans?
Pick green beans every day; the more you pick, the more beans grow. Green beans are picked young and tender before the seeds inside have fully developed. Look for firm, sizable pods that are firm and can be snapped—generally as thick as a pencil. Snap or cut the beans off the plant, being careful not to tear the plant.
When should you pick Bush Beans?
Pick the beans when they are young and tender. This is when the pods contain immature seeds and are still succulent. Bush beans will produce most of their crop over a two-week period. Pole beans will keep producing until the fall frost, as long as the vine keeps growing and you keep harvesting the beans.
How do you grow green beans in a container?
Put two beans into each hole between 1 and 11⁄2 inches deep. Eliminate the weaker one after germination by cutting the stem. (Do not allow two plants to coexist in one hole; neither will thrive.) To care for your container of green beans, provide 6 to 8 hours of sun per day. Whenever the soil is dry, water to a depth of 1 to 2 inches.
