What is the rule of thumb for container gardening?
Container size should be in proportion to plant size. One rule of thumb is the container should be one third as tall as the plant. This is measured from the soil it is growing in to the plant’s tallest leaf. Although you can grow plants in any container, plastic containers are recommended. Even with limited space, you can grow all kinds of amazing vegetables in containers — from greens to tomatoes, peppers to cucumbers, even eggplants, squash and beans.Almost any vegetable that will grow in a typical backyard garden will also do well as a container-grown plant. Vegetables that are ideally suited for growing in containers include tomatoes, peppers, eggplant, green onions, beans, lettuce, squash, radishes and parsley.
How to arrange plants in a container?
One of the best container planting tips is to leave an inch or two between the edge of the pot and the edge of the soil from the plants. This will give the plant room to root-out in all directions. From there you simply want to arrange the plants so each plant has some room and the whole planter will be filled. Whatever type of container you use, be sure that there are holes in the bottom for drainage so plant roots do not stand in water. Most plants need containers at least 6 to 8 inches deep for adequate root growth.
How many plants should you put in a container?
I definitely would NOT put more than one in a 1′ diameter container. I would not put more unless their the kind that stays small.
