Why are the leaves on my hibiscus turning yellow?
My research says artichokes in cold climates are often treated as annuals - meaning, they are replaced each year. However, Cornell University in NY offered this info:
Shorter season varieties that are more likely to flower and winter over in New York include:
Imperial Star - grows just 3 feet tall
Violetto - purplish buds
Grande Buerre - spineless heads, grows up to 9 feet tall
If you want to try overwintering artichokes, dig up the root crown and put it in a plastic bucket with some kind of insulating material, like leaves, newspaper or other mulching material. Thenn wrap the container in burlap or a frost blanket and try to keep it from freezing. They should withstand a light freeze.
You should be able to get them through the winter if they don't freeze too hard. They can withstand cold temps, but not for long and not too cold.

For your hibiscus, this could be a few different deficiencies, but most usually nitrogen. These plants are very hungry and need feeding every few weeks for the best results. This is especially true for container plants.
This article will help you to understand some of the most common reasons for yellowing leaves:
I am not sure if the plants that are growing wild in my backyard are an old artichoke plant or wild cardoons. The leaves have a silvery appearance. I want to make cardoons, and I was wondering if I could cook the artichoke the same way.
I don't advise this, since it has been known to cause an extreme choking hazard. They need to be cut, peeled, and prepared correctly.
It is best to wait for the flower. This article will help: https://www.gardeningknowhow.com/edible/vegetables/artichoke/how-to-harvest-artichokes.htm
The plants are growing well and look healthy.
Typically, this is a sign of nutrient deficiency. If you do not feed your soil, heavily, or add compost frequently, then this is the issue.
They are VERY heavy feeders and will require constant feeding, as they will leach nutrients out of the soil quickly.
Here is an article that will help you to care for the plant:

Hi, Please can you help. I am growing some globe artichokes and I am getting a continual build up of earth on the stems, which I think is being put there by ants. Every time I water the plant I wash it off but it will be back on within one or two days. Please can you tell me (a) if this will harm the plant and (b)what if anything do I need to do or can be done. I enclose pics.
Is it dirt or is it aphids? During my research I noticed the pictures of aphid infestatons looked like dirt.
Try spraying the leaves with Neem oil and see if that stops it.

Hi, I live in Sonoma, Ca, and had to downsize and move my raised garden bed to a different area 1 week ago so I had to move my artichoke to a large planter. We tried hard to dig wide around it and as low under the roots as possible but it is not doing well. I used Liquinox Start vitamin B-1 solution couple days ago but it still appears withered and dying. Is there anything I should do? How often should I water it? Any advice would be greatly helpful. Please see the very sad before and after photos!
Hopefully you got all the rootball. It may take a few more days but they should perk up. Here is some information about transplant shock.

Hello. I live in Northeast Ohio. My husband and I do have a green house that has a heat source in the winter. I cannot find any artichokes to purchase online but I was wondering if you could possibly grow an artichoke plant from a store bought artichoke.
Technically, you could do a tissue culture, but unless you have a flowhood and some hormones on hand it is probably not going to work for you.

The stems range from 10 to a little over 15 feet tall and are very robust. A plant died and after removal and digging underneath it, there are no rhizomes or signs there ever were any.
It is possible a rodent of some kind beat you to it. Make sure the sunchokes get plenty of water as that will promote good tubers. Here is more on their care:
