Beans in pots – Many types of beans thrive not only in beds but also in buckets on the balcony, whether they are ole beans, fire beans, or bush beans. Sowing and planting techniques are discussed.
The time has come to “plant” the beans, as professional gardeners call it, at the very least after the ice saints from mid-May. You must first decide which type of plant you want in the ground before you begin. Planting bush beans is simple and quick. Climbing aids aren’t required because the plants remain low and bushy. They rarely exceed 30 to 50 centimeters in height.

Climbing aids for runner beans can be created from bamboo sticks or wooden planks.
Pole and decorative fire beans, on the other hand, always need a climbing aid, such as special trellises that are available in garden centers. Bamboo poles are also acceptable. It is ideal to tie three or four poles together at the top like a tent. Alternatively, you can put a big post in the bed and string cords from it to the ground.
If possible, bury the climbing aids around 60 cm deep so that they are stable. In addition, the sticks should be high enough: Pole and fire beans can grow up to three meters high.
Plant beans properly
Bean seeds lie in milk.
To soften the skin of the bean seeds, you can soak them in milk overnight.
For pole and fire beans, place around five to six seeds about three to four centimeters deep in the soil surrounding the climbing aid. Bush beans can be seeded in rows, inserting a seed every five to ten centimeters in the seed furrow about three centimeters deep. So that the beans germinate faster, you can soak the seeds in water, chamomile tea or milk overnight before sowing. This saves roughly seven to ten days of germination.
The right location and soil

Fire beans are very decorative. They are therefore also suitable as ornamental plants.
Beans like deep, loose soil. While runner beans also prefer humus-rich soil, bush and fire beans are quite undemanding. In general, beans like locations that are as sheltered from the wind as possible, sunny and warm. But they also thrive in semi-shade. Beans grow particularly well in a mixed culture with corn and pumpkin .
Growing beans in a pot on the balcony
You can also plant beans on the balcony instead of in the garden. Both bush and pole beans thrive well in tubs. However, they do require large, deep planters so that they have adequate room to root. It is also advisable to choose a variety of runner beans that does not grow too high. It is important to keep the soil in the tubs evenly moist.
Beautiful privacy screen made of bean plants
Since climbing beans grow tall quickly, they are also well suited as a natural privacy screen . Fire beans with their bright orange-red flowers are particularly decorative. However, these plants are cross-pollinators and therefore need a second variety in the vicinity so that they not only set flowers but also pods later.

When the beans are ripe, they should be harvested quickly.
The beans can be harvested about two to three months after sowing. The fruit should not ripen for too long, as this will affect the taste. To check if the beans are ripe, simply break open a bean. The vegetables are ripe when the crack is smooth and the inside is green and juicy. The seeds in the beans should be no larger than an inch. Important: Raw beans are poisonous, so never eat them uncooked.
