Known as the father of modern skepticism, Michel de Montaigne (1532-1592) was one of the most influential writers of the French Renaissance.His talent for probing intellectual topics through personal storytelling helped to popularize the essay as a literary genre.Seemingly overnight, a thick stem appeared in the center of each plant, topped with a deceptively cheerful yellow flower.The plant senses its life is coming to an end, so it refocuses its last bit of energy on producing seeds in order to perpetuate the species.Hot weather is usually the cabbage’s trigger for bolting, but sudden exposure to low temperatures at night may also cause plants to go to seed.If Chinese cabbages are detected in early stages of bolting, the flower and stalk may be snipped off to buy a few extra days of harvesting.Plant spring crops earlier by starting indoors and using row tunnels outdoors so cabbage is well established before hot weather arrives.Territorial Seeds offers China Express, a Napa cabbage type that has shown resistance to bolting.Practice “cut and come again.” This means picking off outer leaves of the cabbage as you need them, similar to harvesting loose-leaf lettuce. .

You can learn more on the How to Grow Cabbage page of the Bonnie Plants website.Scout often and diligently for insect pests or cabbage worms around the plant and on the underside of the big leaves, where they like to hide.Yellow leaves could mean many things, from overwatering to Clubroot, a common disease that affects cabbage.Avoid this problem by keeping your plant healthy and your garden free of insect pests, weeds and debris.If your cabbage sends up a flower stalk instead of forming a head, it’s called bolting. .

How to Prevent Cool Season Crops from Bolting

Also known as ‘running to seed’ this is where a plant suddenly, often in a matter of a few days, starts to grow flower stems, simultaneously stopping all useful growth of the vegetable itself.Once the flower shoots form not only is growth slowed as the plants put all their energy into reproducing but they can rapidly become unusable in the kitchen as well.The gardeners job, therefore, is to persuade the plant to put off flowering for as long as possible so that a good leafy crop can be obtained.However, early bolting can be triggered by abnormal weather conditions or by leaving them in the ground over winter followed by a mild spring.Many salad brassicas fall into this category: Chinese cabbage (pak choi), mizuna and arugula are good examples which are all best sown in mid to late summer.Weather is by very nature always unpredictable, so sowing a few plants every two weeks or so will guarantee that some of them should do well, whilst still giving you some early harvests before they bolt.Meanwhile, I am busy making regular sowings of other spring plants under cover which should start to fill the gap in a month or two.Bolting may be an inevitable outcome of longer spring days but I am determined to use every bit of ingenuity to minimize its effect and get a great range of early salads. .

Bolting – The Bad Kind of Flowers: What Is It, Why It Happens, and

This occurs as a natural attempt to produce seeds – a means of survival when a plant is put under stress and feels that it is in danger.Because once flowering is triggered, nutrients are diverted away from the stems and other vital parts of the plant that can be consumed and sold.Disease problems, insect infestations, and insufficient water or minerals are also likely culprits.Plants that are highly susceptible to bolting are lettuce, assorted herbs, beetroot, brassicas, spinach, celery and onion.It’s no surprise that temperatures that border on freezing will endanger the plant, but this works just as much on the opposite end of the spectrum.As spinach and cabbage are both extremely sensitive to over-exposure and excessive sunlight, one way to avoid bolting is to wait longer into the season to put down seeds.Direct sun during long summer days will wreak havoc on your plants.Row covers are frequently used to keep cold weather crops producing longer.When plants are crowded together you get competition effects either for light or for nutrients and yields are reduced.A dense layer of mulch will help keep the roots cool and prevent the broccoli from bolting. .

Bolting in vegetables / RHS Gardening

In annual crops, bolting occurs before they are ready to gather and, in biennials, when an over-wintering organ (carrot roots for example) flowers before the winter.This is due to unsettled weather conditions early in the season and usually occurs after a prolonged cold spell, often during the propagation phase. .

How to Stop Lettuce From Bolting

Many of these seeds will have names that hint at their bolt resistance, like "Slobolt" and "Summer Bibb.".It's a good idea to test with a soil thermometer to be sure you've achieved the correct temperature for your seeds to sprout.Row covers also protect greens and cold-season crops from pests such as cabbage loopers and rabbits.You will need to provide supports along with the cover to keep the cloth elevated above the plants and giving them room to grow. .
