What kind of vegetables do you like?
I grow tomatoes, peppers, kale, cucumber, eggplant, ginger, mint, basil, thyme , sage, rosemary, marjoram, strawberries, green onions, beans, peas, and citrus trees all in pots.
Many of the herbs like basil, coriander (anything in the parsley family)lavender, borage attract beneficial insects
basil and tomato go well together in the garden and on the table but dill and tomato and beans and onions do not.
If you want tea plants, lemon verbena, lemon balm, chammomile, lemon grass and any of the mints make great teas.
Containers need more watering and you need to pay attention to nutrients.
The larger containers are best since they dry out slower and have much more root space.
I use 18 gallon containers for indeterminate tomatoes, beans peas, cucumbers, citrus trees ginger, bay leaf, and cardomom.
Peppers would rather be in the ground but do ok in 1-2 gallon pots
Mints are in 6-14 inch pots, hanging baskets or bowls. They need to be controlled
Lemon grass needs to be potted up frequently
I have grown green onions, stevia, cilantro, basil, sage,thyme, parsley, strawberries in in window boxes. Styrofoam boxes from the fish dealers or restaurants make good deep containers. Choose a deep window box or construct one for yourself. Rain gutters actually made good hanging gardens on walls and fences but they are shallow and need frequent watering.
If you want to companion plant in a pot it can be done
I put herbs that like the same conditions and don't take over in the same pot
Thyme, marjoram, lavender, sage can stay together for a while. Eventually the bigger plants will either need to be pruned or transplanted out. Lavender tall, thyme creeps, marjoram is bushy and can be pruned to stay short. Broadleaf sage is shorter than garden sage.
Plants that need to be alone mints very invasive they take over and have to be divided frequently
Strawberries better in their own space.
Together Basil and tomato in 18 gallon pot with trellis
Cucumber on a trellis with cilantro or parsley 18 gallon pot. Need a lot of water, and the larger pot will dry out slower
Peppers in 1-2 gallon pots. Need to be spaced out more as they grow.
Ginger 5 gallon pot, needs the space for the roots to grow
green onions, cilantro, stevia, basil in a styrofoam fish box ( a deep window box.)
Rosemary, bay leaf, lemon grass, citrus trees each in their own pots. They need to be potted up as they grow.
Lettuce different kinds in a rain gutter or deep window box.
Add some flowers to attract beneficials and a lot of flowers are edible too.
Dwarf French Marigold the gem series attract beneficials and deter nematodes. Flowers are edible but are bitter.
Nasturtiums, pansies,violas, borage, pineapple sage, calendula, scented geraniums, pineapple sage, borage, roselle, daylily, violet, anise hyssop, squash blossoms, Cooking banana hearts, chives flowers,
pea shoots, sweet potato leaves, begonia, and sunflower seeds (mammoth has the largest seeds)
