Growing Yellow Wax Beans: The Secret Is Patience
Every spring, I get the same question: "Why won't my wax beans grow?"
The good news is that yellow wax beans are one of the easiest vegetables to grow. But they do have one requirement that catches many gardeners off guard. They hate cold soil.
Many seeds rot before they ever sprout because they're planted too early. If the soil is still cool and wet, the seed can sit there for weeks without germinating.
So if you want to give your wax beans the best possible start. Wait for Warm Soil. Don't plant by the calendar.
To plant correctly , you need to wait until the danger of frost has passed and the soil has warmed to at least 15°C. Even better is 18–21°C. To get a quick, even germination. In much of Nova Scotia, that usually means late May to early June.
Other tips? Sow seeds 1 inch deep. Planting much deeper can delay or reduce germination.
When planting, space the seeds 2 to 4 inches apart, in rows 18 to 24 inches apart. Good airflow helps reduce disease later in the season.
Plant them in full sun, they thrive only if they get 6 to 8 hours of direct sunlight every day. The more sun the more beans.
Keep the soil evenly moist while the seeds are germinating, but once they reach about six inches tall, you only need to add about one inch of water per week, and that would include rainfall. You need to avoid constantly soaking the soil.
Remember that beans make their own nitrogen, so don't add a high nitrogen fertilizer to the soil. Fertilizer can produce lots of leaves, but very few beans.The simplest thing to do, and what I like to do, is to just add a little compost into the soil before planting. .
The last tip is just to pick often. The more you harvest, the more the plants produce beans. Never wait until the beans become large and tough. Pick them when they're young, smooth and tender, usually every couple of days during the peak season.
Common Reasons Wax Beans Fail? That's simple. They're planted into cold wet soil, they're planted too deep.They're planted in heavy clay soil that stays waterlogged, you use too much nitrogen fertilizer, and rabbits, slugs or beetles are eating the young seedlings before you notice.
Look, growing wax beans isn't difficult. They simply reward good timing more than almost any other garden vegetable. Wait for warm soil, give them plenty of sunshine, and they'll usually reward you with weeks of fresh, buttery-yellow beans.
