Being disabled, there are some obsticals.
I farm in buckets. Peppers mainly. I use those big drywall buckets. They are called 5 gallon buckets but that is a misnomer as they hold more than that. once planted there is lottle to NO weeding whatsoever if you keep them up on a deck elevated from ground. Just water when they get wilty.
I have had peppers live 8 to 10 years by bringing them inside when it gets cold in the fall and then again back out in the spring when it warms up. The pepper plants take on an appearance of small trees after the first few years.
Just put a few holes around the bottom of the bucket with a large (ten penny) nail and use gravel in the bottom 3 inches for drainage. That may be a remedy for your drainage problem. Works very well with peppers of all kinds, onions, carrots, herbs, spices.
On the other hand, tomatoes, corn, watermellon, cantelope do NOT work at all in buckets.
