As I looked further into companion planting I also found some good information on the use of containers to increase production on a smaller footprint. Even though we have plenty of land in which to expand, some types of container planting seemed more efficient. The most appealing to us was the idea of growing potatoes in barrels.
Potatoes work well here, but take up a lot of space. We decided we would try one barrel so we could compare the results with our field grown potatoes. We got a new large container (yes, it is a trash can) and put some seed potatoes in it.
As they grew we added more mulch to cover them up. They grew fast. We were adding more mulch almost weekly. Much easier to do than hoeing in the rows of potatoes,
We were given a large quantity of left over seeds potatoes by the local hardware store, over 50 pounds. Even though we have yet to harvest the first batch of barrel potatoes, the new fields are not ready, so barrels are the only option. We estimate we will need around 10 barrels. Using trash cans is pricey, so after a little research we found some inexpensive food grade barrels. They are perfect.
We have a couple of other containers going as well. There are some plants that have not done well in the field garden, or that we only grow small quantities for personal use and therefore prefer closer to the house for easy access.
A couple varieties of squash interspersed with corn and radishes. Corn does not do well in the big garden because it attracts a variety of wildlife that like to eat it. Radishes are just there for the beneficial effect. We put these containers in the patio area off the basement which has 4-5 foot retaining walls on all sides. This area is not visited by deer, bunnies, racoons or other creatures because our dogs like to hang out there.
Some tomatoes, peppers and basil.
Newly added. Cucumbers and dill in the red container, companions in life and in death!
