We have planted one artichoke plant this year. The leaves are quite large but there is no fruit. Why?
The part we eat is from the immature flower bud. If the buds or "globes" are not harvested, then the 6-inch bluish thistle-like flower heads develop. The edible portion of the "globe" is composed of the fleshy bases of the flower bracts and the receptacle to which the bracts are attached, known as the "heart". When harvesting, you should choose one that is dark green and it should be tight and compact. Avoid those that are beginning to open.
I planted artichoke by seed and repotted them. I want to know if I should plant them into the garden now or wait until spring. Also, do they need to be protected from cold? I live in zone 7b. There are 4 plants in 2 of the pots and 2 in another. Are in 5 gallon pots.
You may have difficulty growing Artichoke in your garden, due to the temperatures and the length on growing time needed for plant production.
You can try keeping them outdoors while the temps are warm during the day, then moving indoors for the evening.
If the them temps become to cold, you also can try adding a grow light indoors.

I planted some good artichokes this year and most of them did well during a very hot summer. Now with autumn already kicking and a good portion of grass around I'm wondering what should I do to properly keep them till next year. It's the first time I planted then so unsure how to best treat them during autumn and winter in my mountain area. It's a valley but still rough. Love artichokes, so I wanna keep them well. Kind regards miguek Veiga

How can I eliminate earwigs quickly on my artichoke plants? What can I spray on the plants using natural ingrediants
My secret recipe for earwigs is to make earwig traps. Take a basic plastic container with a lid, I usually use a container from sour cream or dip. Wash out the container and using a hole punch, punch 4-6 holes just under the container lip. Pour a little vegetable oil & soy sauce in the bottom of the container, this should shallow, about 2-3cm deep. Place the lid back on and stick this trap under or next to the plants being attacked. The soy sauce lures the earwigs in but the oil makes it so they can't get back out.
What causes the bracts to start opening on a small artichoke? I would like the artichoke to grow to a larger size before having to harvest.
Artichokes are heavy feeders, and too little fertility or too little water can cause smaller heads. Also, reducing the number of shoots growing from each plant is supposed to increase the head size produced on the remaining shoots. Artichoke plants grown from seed are genetically variable, and this can affect the size of the artichokes.
