Growing Beans: How and When to Plant Pole and Green Beans

By: Angela Judd | January 29, 2025

Beans are a warm-season legume grown for their tender, tasty pods. They are prolific, easy to grow, and come in many varieties—from bush beans to pole beans, string beans, and yardlong beans. If you’ve ever wondered when to plant beans or how to get the best results from your green bean planting, you’re in the right place! This post will cover everything you need to know about bean planting. We’ll also touch on pole bean planting techniques, container growing, and troubleshooting common problems.

1. Types of Beans

Thinking about the right type of beans for planting? One of the most fun steps in beans planting is choosing a variety that fits your space and flavor preferences. Whether you want a quick harvest from bush beans or a taller pole bean plant that grows over a trellis, understanding these types will help you grow beans that suit your garden perfectly.

Bush Beans

Growth Habit: Compact plants growing close to the ground.
Harvest Window: Typically ready in about 50–60 days. They produce one large flush, then a smaller crop.
Tips: Succession plant every two weeks for a continuous supply. Try ‘Dragon Tongue’ or ‘Gold Rush’ for unique flavors and colors. ‘Contender‘ and ‘Jade‘ are reliable varieties.

Pole Beans

Growth Habit: Climb a trellis or support, often reaching 6–8 feet (1.8–2.4 m).
Harvest Window: Usually 60–70 days. A single planting can yield beans all season.
Tips: For pole bean planting, look for stringless (when young) varieties like ‘Kentucky Wonder’ or ‘Blue Lake.’ Provide a sturdy structure for them to climb.

String (Snap) Beans

Not sure if string beans and green beans are the same? Traditionally, string beans had a tough fibrous string running down the pod seam, which had to be removed before eating. However, most green beans for planting today are stringless, making them easier to prepare.

What Are String Beans? These are the classic “green beans” you snap. If you want green beans for planting, you can’t go wrong with snap beans. All string beans are green beans, but not all green beans are string beans anymore!

Yardlong (Asparagus) Beans

Heat Tolerance: Ideal for hot, humid conditions. Known as snake beans or Chinese long beans.
Fun Factor: Pods can reach 18 inches (45 cm) or more, fascinating kids and adults alike.
When to Plant: They require warmer soil than green or pole beans, so plant them later in spring or summer.

2. How to Plant Beans

Planting beans is pretty straightforward, but a few tips will make sure your string beans growing experience goes smoothly.

Direct Seeding: Beans usually do best when sown directly into the garden. Transplanting can disturb their roots, so grow beans directly in their final location if possible.
Depth & Spacing: Plant seeds 1 inch (2.5 cm) deep and 2 inches (5 cm) apart.
Germination: Look for sprouts in 5–10 days. Ideal soil temps range from 60–95°F (15–35°C), with around 80°F (27°C) being optimal. When the soil is warm, I’ve had beans pop up in 2 days!
Sun & Water: Full sun (6–8 hours daily) and consistently moist, well-drained soil are key to green bean growing.

Seed Starting Note: If you do start seeds indoors, they’re typically ready to plant out in 2–3 weeks. But direct seeding is often best to avoid transplant shock.

3. When to Plant Beans

Wondering when to plant green beans so you can get the biggest harvest? Timing your bean planting is crucial for healthy growth and maximum yield, especially if you live in a region with specific temperature or frost constraints.

General Guidelines

First Outdoor Planting: 2–8 weeks after your last frost date (or right on the last frost date in milder climates).
Last Planting Date: Aim for about 10 weeks before your first fall frost.
Succession Planting: Sow new beans every two weeks for a continuous supply throughout the season.

Specific Recommendations for the Low Desert of Arizona

Snap Beans (Bush & Pole): Plant from March 15–April and again from August–September.
Lima Beans: Plant from March 15–April and July–August.
Yardlong Beans: Plant from March 15–July.
Pinto & Tepary Beans: Plant in March and again with monsoon rains (July–August).

Tip: Warmer soil (70–90°F / 21–32°C) leads to faster germination. If you’re still unsure when to plant beans, err on the side of waiting until the soil warms up in spring.

4. Companion Plants for Beans

Looking to make every square foot count when you grow beans? Companion planting can help maximize yields and even reduce pests naturally.

Good companion plants include:

Corn – Tall stalks support climbing beans.
Carrots – Different rooting depths help use soil efficiently.
Marigolds – Natural pest deterrent, plus a pop of color.

5. Harvesting Beans

Excited to see your string beans growing in abundance? Knowing when to pick them ensures top flavor and encourages the plants to keep producing.

When to Pick: Harvest when pods are firm and about the thickness of a pencil.
Pick Often: Frequent picking signals the plant to produce more pods. If pods mature too much (seeds bulging), the plant may slow down or stop producing.
Storage: Fresh is best! If you can’t eat them right away, store them in the fridge in a breathable bag or my favorite produce storage containers.

Nutritional Bonus: Beans are packed with vitamins A, B, and C, plus calcium and iron.

6. Bean Troubleshooting & FAQs

Why Did My Seedlings Disappear?

Possible Culprit: Pill bugs or slugs often munch on tender seedlings.
Solution: Use an organic slug/pill bug bait and read this guide for prevention tips.

Can I Grow Beans with Corn & Tomatoes?

Yes! Beans fix nitrogen, helping heavy feeders like corn and tomatoes. Just make sure everyone has enough space and light.

Growing Beans in Containers

Container Size: Aim for at least 12 inches (30 cm) deep. If you’re planting pole beans, provide a sturdy trellis or stake.
Soil Mix: Use quality potting mix with compost. Ensure good drainage.
Watering: Containers dry out faster, so water as needed to keep soil consistently moist.

Bush Beans vs. Pole Beans: Which Is Better?

Bush Beans:
- Harvest in ~50–60 days.
- Compact, minimal support needed.
- One large flush, then a smaller second harvest.
Pole Beans:
- Harvest in ~60–70 days.
- Require a trellis or pole, but produce continuously.
- Great for vertical gardening in smaller spaces. Get ideas for trellises in this guide.
