How to grow French Beans
About
French Beans are ideal to grow in the garden and in the allotment. The French Bean plant will only grow around 60cm in height so not as tall as the runner beans which can grow to 10ft. One of the other differences with French Beans and Runner beans is that the French Beans will not produce as many pods. French Beans should not have any issues with the flowers setting and producing pods. A lot of the varieties of runner beans have been cross bred from french bean genes to help them produce beans.

Where to grow French Beans
When choosing an area to grow French Beans they need to be planted in soil that is in a sunny warm spot that holds water and moisture well but it can be too wet and soggy. Choose the area in autumn and winter. Once you have chosen the area add some well rotted manure or compost to the area to improve the soil.
How to sow French Beans
If you are sowing French beans straight outdoors you need to be careful as they do not like frost at all. Wait until the chance of frost has passed then plant the seeds outdoors. If you do want to plant them outdoors earlier put a plastic cloche over the top to protect the young vulnerable plants from getting frost damage.
The best time to plant french beans outdoors is the end of spring or mid summer so you miss the chance of the frost and them getting killed or damaged from it. You can plant both varieties of French Beans – Climbing beans and dwarf beans outdoors from mid summer and they will last until mid autumn till they die off from the cold, they will not survive the winter.
To sow the French beans outdoors dig two trenches around 6cm deep and 12cm apart. Plant the beans in the trenches to the recommended spaces as per the seed packet. Cover with soil or compost. If you are starting your French Beans indoors plant them in seed trays or ideally plant pots. Put a couple of beans per plant pot. Let them grow to around 8cm before planting outdoors. Before you plant them outdoors make sure you harden the plants off for around 12 days though so they get used to the drop in temperature.
How to plant French Beans
When you are ready to plant your French Beans outdoors you need to make sure that the soil has been prepared in advance by adding well rotted manure to it and that it is weed free. Make sure that the area is in a sunny position and the ground is well draining.
You need to work out what you need to support your beans. Dwarf French beans do not need supports but the climbing French beans will need supports as they grow quite tall. You can grow the climbing beans up netting, chicken wire or up garden canes like you would runner beans. The reason for growing them upwards and not trailing along the floor is that the slugs and other animals will eat them and destroy the crops.
Caring for the crop
French Bean’s don’t take much care and attention. If you are growing the climbing french bean make sure that you pinch out the top of the climbing bean plants once they reach the top of the canes. This is so that they can bush out. You can grow them to around 6ft.
Keep the plants well watered especially in dry periods. You can keep the plants moist by adding mulch round the bottom of the stems.
How to harvest
This is the best time picking the produce. You know the beans are ready to be picked when the pods just snap off the plant. Make sure you pick the french beans off when the beans just start showing through the pods. Don’t let them swell too much. French beans will start producing around 12 weeks after sowing.
Like runner beans the more you pick the French beans the more they will produce. You could be picking French beans for a few week. Your friends will love you as you will probably have to many to eat yourself.
One handy hint is that once you have picked them all you should keep watering them as you might get a second crop on your French bean plants. The French Beans won’t essentially be big but they will still taste delicious.
Pests
There are a few pests which can affect French Beans. Here we will try and help you prevent them.
Slugs:- When young plants are popping through the ground they will be more attractive to slugs, especially in damp weather. One tip is to plant them in pots first and wait until they are big before planting out. You can always protect them by putting plastic bottles round them until they are bigger and can survive
Pigeons:- They will love to see new shoots popping through the ground like the slugs. You can again put bottles round them or protect them with netting so nothing can get to the plants.
Aphids:- Greenfly and black fly like French Beans. You can spray plants with soapy water which will hopefully kill the aphids and the eggs off.
Facts
Did you know the French Bean was originally brought from South and Central America by Christopher Columbus and was very popular in France. The green French Beans are the ones you will see most commonly but you can get them in purple, cream and yellow.
Freezing French Beans
When freezing French Beans they are best frozen when the French Bean pods are still young and small. They will taste best when they are that size. If you want you can dry French beans as well. Wait until the pods on the plant start to die off, then pick the pods and lay them some where dry so that the pods dry out. Then you can store the beans in a airtight jar. Before cooking the dried beans though you will need to soak them.
Cooking French Beans
The best way to cook French Beans is to boil them for around 5 minutes in a pan. Make sure you have trimmed away the stems before cooking though.
