Yes. It will , but it can only extended to about 12” tall.
These plastic self-watering inserts will fit planters up to 18" in width.
I am not sure. But I can say that this did not work well at all. Save your money and come up with a different solution.
The adjustable spout when fully extended is about 10"; there is a water level indicator that I found difficult to see based on the angle of where it is located when installed in a plant container. So I relied on looking into the water refill tube itself to see if I could see the top of the water level there. I ended up refilling the reservoir every 2-3 days in mid-summer anyway. Bottom line: this product did not work well for the multiple plants I tried in the various containers I used but, with a northern exposure in a high-rise building, I can't blame the product for failing to meet my needs. With a kinder location including some direct sun and without exposure to harsh winds, this product may be the ideal solution for your container gardening.
To be honest. I sent mine back. It didn't perform like it was suposed too.
Yes, this did not work as I thought it should have.
It may break by inserting. I planted it in the soil. I was disappointed in the performance. I sent back.
Just regular old plastic. I would ask manufacturer about the specifications of the plastic. Online!
It doesn't say but I'd estimate the reservoir holds at least 12-16 oz of water
My containers are 24" and 31" in diameter -- I'd say plan to use two inserts for any container larger than 30"
