Green beans are a warm-season vegetable that do best when planted in late spring or early summer But what if you didn’t get your seeds in the ground during the ideal window? Is it too late to plant green beans if you missed the early summer planting time? The short answer is it depends. With careful planning, you can still get a good late crop of green beans.
Factors That Determine If It’s Too Late to Plant
Several factors play into whether it’s too late in the season to plant green beans
-
The weather in your area and when the first frost will happen—the farther north you live, the shorter your warm growing season. Plant beans 50 to 70 days before the first frost in your area. Gardeners in the south have more time.
-
Green bean variety – Pole beans and other long-season types need more time to mature. Opt for fast-maturing bush bean varieties if planting late.
-
Not adding beans now because other plants have already taken up too much space in your garden. Prioritize fall crops like lettuce and brassicas instead.
-
Motivation level – Be honest about whether you have the energy for a late crop. It takes effort to keep beans watered and producing through summer heat.
How Late Can You Plant Green Beans?
Guidelines on last planting dates for green beans:
- Northern states: Between June 15-July 1
- Middle states: July 1-July 15
- Southern states: July 15-August 1
These dates are general guidelines. Check with local experts to dial in your optimal late planting window.
When planting for a fall harvest, get beans in the ground 8-10 weeks before your first expected fall frost. Fast-maturing bush beans planted in late summer can produce until cold weather sets in.
Tips for Successful Late Plantings
If your analysis suggests you can still get a late green bean crop, use these tips to boost success:
-
Choose short-season bush bean varieties that mature quickly. Good options include Provider, Contender, and Derby.
-
Use row covers to help moderate soil temperature. Prevent soil from overheating or getting too cool.
-
Provide trellises and supports. Sturdy tepees or cages prevent sprawling plants.
-
Prioritize consistent soil moisture with drip irrigation or diligent watering. Beans need steady water.
-
Scout for pests like bean beetles that thrive in mid-summer. Be prepared to manage them organically.
-
Harvest frequently to encourage more pod production. Don’t let beans over-mature.
If you plant green beans late, they can still produce if you do it right and take good care of them. Before you plant, take an honest look at your climate and why you want to grow plants. You can pick beans well into summer or early fall if you use varieties that do well in heat, protect them from temperature changes, and give them lots of care.
A late planting of beans
When putting in a late planting of beans you need to keep a couple of things in mind.
1. The days to maturity of the variety you have chosen. 2. The declining amount of sun as you move towards fall.
What varieties to choose for a late planting of beans
In order to be successful with a late planting you really need to have at least 75 days until your first real threat of frost.
This also means you need to choose varieties that have a pretty short maturity date. Green beans will really be your only choice for a late planting of beans. And I would recommend that you choose bush varieties, not pole beans.
Bush beans spend a lot less time growing plant material and seem to just get into the business of growing beans a lot quicker. There are a lot of tasty varieties of bush beans that have maturity dates right around 60 days. I would suggest choosing one of these varieties.
