Ideal Time to Sow French Beans

Wondering when to sow French beans in the UK? French bean seeds should ideally be sown indoors in April on an open window sill where they may receive lots of sunlight. In late May, take them outside and place them in a warm, sunny area. Even a mild cold spell might be fatal. Before planting or direct-sowing outdoors, wait until all potential for a late frost has passed. The best time to seed French beans is between April and July if you want to grow them successfully.

We can do preliminary sowings in pots under cover, and when the weather warms up, you can plant outside (or slide seedlings outside in grow bags). It’s a good idea to warm the soil with a cloche beforehand if you decide to direct-sow outside. Temperatures of the soil and compost must be at least 10°C (50°F). The best results often come from May seeding. You can seed beneath stiff cloches a little earlier if your soil is light and well-draining and you reside in a little warmer region, such as the southern UK.

Choosing the Type

Common beans include green beans and French beans. They are called snap beans, snaps, string beans, and haricot vert. Their scientific name is Phaseolus vulgaris. There are two types of French beans: Dwarf beans and climbing beans. Beans that are dwarf are ideal for confined settings because they thrive in the ground and containers. Although they grow best in the ground and require tall supports, climbing beans can also be grown in substantial pots. Climbers produce a significant yield in a relatively small amount of ground as they develop vertically. Since dwarf beans only produce for a few weeks, you must repeat sowings to ensure a summer-long supply. Despite taking longer to reach the cropping stage, climbing beans will produce beans over an extended period of time.

Some popular varieties of dwarf beans include ‘Borlotto’, which boasts colourful mature pods that are ideal for drying and have a pleasant texture and flavour. ‘Purple Teepee‘ is another popular choice, producing abundant harvests of eye-catching purple pods up to 15cm long. In the case of climbing beans, there is an Italian variety named ‘Borlotto Lingua di Fuoco Nano‘, which has spectacular pods splashed with red. ‘Hunter’ is a variety that produces large crops of stringless, flat pods up to 20cm long and has good disease resistance. ‘Sansoucy’ is another climbing bean that produces beans high above the foliage and can grow up to 45cm tall and 30cm long. Whatever variety of beans you choose to grow, they are sure to add colour, flavour, and nutrition to your garden and your meals.

How to Grow French Beans

French beans must first be sown inside starting in April before they get transplanted outdoors after the final frost, which is often in late May or early June. Continue to sow beans every three weeks until the beginning of summer for a yield that will last until the following fall.

One can do later sowings outside, but seedlings need to get protected from the elements with a cloche. Planting dwarf French beans 15 cm apart eliminates the need for staking. Growing climbing French beans alongside sweet peas on a wigwam-like structure of canes in the flower border looks particularly lovely.

Opt for a warm, sunny growing location. Thoroughly weed the area, then add a lot of well-rotted manure or garden compost (at least two bucketfuls per square meter/yard) to the soil to help it retain moisture. To give the ground time to settle, this should preferably get done a few weeks prior to sowing or planting or even the previous autumn if you have enough time to design your growing location.

Once the weather (and ground) are warm enough, you can direct-sow French bean seeds outside in the ground or in containers if you intend to grow them there. Emerging seedlings require cover at night, such as a cloche. You can sow them in modules or 3.5″ (9 cm) pots under cover if you wish to grow them indoors.

This enables plants to produce fruit two or three weeks earlier than with straight outdoor seeding. Use potting compost and make sure the pots you use have drainage holes. Give the compost plenty of water and let it drain.

Water plants frequently, especially while they are blossoming, to ensure a good yield of beans. Applying a garden compost mulch will keep the soil around the roots moist. Depending on the variety and season, beans grown from seeds straight in the garden are generally expected to be ready for harvest in 45 to 72 days. French beans are prolific producers once they get going.

To keep the crop producing and for softer, better-tasting pods, harvest frequently—every day or two. Picking beans while they are wet increases the danger of disease spread since pods are readily bruised. Beans can be frozen after being blanched in boiling water for a couple of minutes if you don’t want to consume the entire harvest right away.

Points To Remember

• Keep in mind to water thoroughly and frequently when you first begin to cultivate French beans. Particularly when the plants are flowering and podding, these plants will require a lot of hydration.
• Don’t hesitate to soak them thoroughly using a watering can, especially during dry seasons.
• These plants work hard to reach deep into the soil with their roots in order to take up as much nutrition as they can. However, you can also assist French beans in this situation. Every two weeks, you should feed these plants a high-potash meal like liquid tomato feed. This will increase the likelihood of your beans producing more.
• Keep weeds out of the growing area. Consider planting through weed-suppressing membrane slits to lessen weeding requirements and avoid damaging dwarf bean pods from soil contact.
• Because French bean blossoms self-pollinate, plants cultivated from saved seeds are probably true to type.
• Leave a few pods to fully mature at the end of the cropping season, then harvest once they have dried.

How To Deal With French Bean Problems?

A condition known as bean mosaic virus is contagious in some varieties of French beans. Yellow spots on foliage and reduced development are telltale symptoms. There isn’t much you can do to salvage infected plants, but you can choose French bean types like ‘Golden Gate‘ and ‘Monte Gusto’ that naturally resist the disease. Black bean aphid assaults can also harm French bean plants. If the plant is impacted, black clusters will be visible around the leaves tips. Use a powerful water jet to regulate populations or crush them. Silvery trails left by slugs and snails are frequently seen on the leaves of newly planted young plants. Wrap plants using big plastic bottles that have been “topped and tailed” to combat this. The presence of white spots on leaves indicates a fungus infestation. If the weather is consistently very moist, this may occur. Although there is no cure for this, the plant can still get saved, and the beans will still be palatable.
