How do I grow princess beans or green beans?
Princess beans are annual plants that are best sown or planted when the risk of night frost has passed. After the Ice Saints is also sometimes said. This is after May 15. Logical, the origin of the plant is warm Mexico and South America. To get a quick start, you can pre-sow the beans indoors, 3 to 4 weeks before the last frost date, so now approximately. To pre-sow beans, you can use deeproot trays . These are specially made for pre-sowing legumes. If you always want fresh beans until autumn, sow them every two weeks spread over the season. The harvest from your last sowings in September/October will give you beans throughout the winter if you freeze them. You can continue to harvest beans until the first night frost. Keep in mind that the plant does not produce beans above 26°C.

How to grow pole or princess beans - Description
Princess beans , also sometimes called runner beans , are as mentioned before annual plants and are grown in our vegetable garden to eat the green, immature fruits of the plant. A mature bean is tough and has large seeds in the pod that are not so tasty. That is why we harvest them on time. The color and size of the beans varies according to type. You can find princess beans in green, yellow, speckled and purple. The pods can be 7 to 10 cm long, but beans of 15 to 20 cm also exist. Leaves usually come in threes. The flowers are yellow, purple or white. Pole or pole beans can grow up to 2 meters in 60 to 85 days. As the name suggests, the latter need the support of a stick or stake. Of course, pole beans produce more than bush beans .
How to grow pole or princess beans - Yield
Grow 4 to 8 plants per family member
How to grow pole or princess beans - Place
Give beans a sunny spot in your vegetable garden, they come from warm places. They also grow in the vegetable garden in partial shade, but in that spot the harvest will not give the maximum yield. The plants grow best in loose, well-drained soil rich in organic material. Incorporating tarred
compost into your vegetable garden soil is ideal for this. Beans like a pH neutral soil (Ph 6.0 to 6.8). So definitely work with tarred
compost or manure, this is better balanced in terms of acidity than fresh. Avoid soil with a high nitrogen content. Soil where green manure was is also not suitable. Your plants would produce a lot of leaves but few beans.
How to grow pole or princess beans - Plants
Beans are tender annuals and grow best in temperatures between 15° and 30°C. Sow the beans after 15 May when the soil has warmed up a bit. If you have a cold spring, you can easily wait a few more weeks. Indoors, you can start three to four weeks earlier (mid to late April), but it is best to plant your beans at the end of May. Provide pots that are deep enough to store the plants indoors for 6 weeks.
Beans develop a deep root system very quickly. Once the roots become entangled, the plant suffocates and declines.
Deeproot trays are ideal for pre-sowing
beans . There is enough space to develop a good root system. With the
professional push-out plate, you do not disturb the roots. For a continuous harvest, you can sow beans in a staggered
manner . Or you can sow bush
beans with a shorter growing time at the same time as
pole beans that have a longer growing time (see above).
How to grow pole or princess beans - Distances
Sow beans 2 to 4 cm deep. In sandy soil you can plant a little deeper, in clay soil a little less deep. Sow or plant bush
beans 8 cm apart and the rows 40 cm between the rows. For
pole beans, place a stick every 50 cm that you place diagonally opposite another stick. The sticks are about 70 cm opposite each other. Around each stick you place 5 to 6
seeds at a distance of 5 cm around each stick. You can also place two
seeds in each planting hole, that way you play it safe. In that case, after germination, remove the weakest plant in places where both
seeds have germinated. Cut the young seedling just above the soil, make sure you do not damage the other one.
How to Grow Pole or Princess Beans - Water and Food
Grow
beans in a garden soil that is evenly moist.
Bean seeds can crack, rot and germinate poorly or not at all in soil that is too moist. Pre-soaked
seeds are very vulnerable in the open ground and can easily rot away. Indoors, you have control over the moisture of your potting soil or sowing and cutting soil and pre-soaking is a good option. Keep your soil evenly moist during the growing season as well. An even moisture during the flowering phase and the moment the plants form pods is very crucial for a good harvest. After the soil has reached a temperature of 15°C, a layer of mulch can do wonders here. Mulch ensures that the water evaporates less quickly. Straw or wood chips are a good option as a mulch material here. I prefer straw because I can remove it more easily than wood chips.

Beans are best fed with tarred
compost , they do not need extra nitrogen and live on the sun, water and the nutrients present in the soil. In addition,
beans get the growth substance nitrogen from a very nice phenomenon. The root system of
beans sets up a kind of nitrogen exchange system with micro-organisms that are present in a healthy vegetable garden soil. The
bean plant feeds those micro-organisms (bacteria) and gets nitrogen in return. So avoid nitrogen or green manure for growing your
beans in the vegetable garden.

How to grow pole or princess beans - Care
Work the soil around the plants lightly, avoiding contact with the superficial root system. Leave the
bean plants alone when they are moist, this can prevent the fresh
spreading of fungal spores. Set your stakes first, then your plants, also choosing stakes that are high enough for the variety you are planting.

How to grow pole or princess beans - harmful insects Diseases
Princess or French
beans can be attacked by aphids, leafhoppers,
bean beetles, flea beetles and mites. Aphids, leafhoppers and mites can be sprayed away with a jet of water. However, catching them early is even better. Watch out for eggs and crush them between your thumb and index finger. If there is a large concentration of insects, prune away the heavily infested parts of the plant. Keep your garden clean at all times, this makes it harder for harmful insects to find a home in your vegetable garden and to overwinter.
Beans are susceptible to mildew, mosaic and anthracnose. Keep your garden clean and avoid collecting waste. Avoid contact with your plants when they are damp, so that you do not
spread mould. Throw away diseased plants, do not throw them on the
compost heap. If you were to grow
beans in the same place in your vegetable garden every year, you increase the chance of soil diseases. So rotate your pod bed every year and grow
beans in the same bed every 3 years at most.
How to grow pole or princess beans - Harvest
Bush beans are ready for harvest 50 to 60 days after sowing.
Pole beans take a little longer, 60 to 90 days. Harvest the beans on time, before you see the
seeds getting fat inside. Continue harvesting throughout the season, this will encourage the plant to produce more flowers and therefore more fruit. When the
seeds mature, the plant considers its task as done and the plant will die. Do not harvest when it is extremely hot or cold. Harvest the beans with scissors, pulling on the beans can damage the plant.
The most well-known varieties are:
- Shrub: Maxi BIO , Ferrari BIO , Miracle Chinese , Argus Extra Long , Butter Queen (yellow), Delinel , Larma, Prelude , Purple Queen (purple), Saxa or Limburgse Vroege ;
- Pole: Neckargold (yellow), Abundance – Rent Giver ; dried beans (pole): Borlotto Firetongue, White Egg Bean ; dried beans (bush): White Egg Bean , Lapwing ;
