After discussing general tips on growing plants in containers and location of plants in containers, it's time to discuss watering and fertilizing of plants in containers.
growing in containers is a completely different culture than growing in
the ground, do not use garden soil nor potting soil in a container.
These heavy soils will not allow enough air to the roots of the plants
in containers and may ultimately kill the plants. Instead, buy a soil
less mix or make your own with wood chips, perlite, and peat moss. If
planning to use organic fertilizer, it's fine to also add a bit of
compost to the mix- no more than a sixth of the total mix, as compost
can become quite heavy and thick.
Be sure to check every day for dryness within the container. Do not allow soil to dry out during the growing season, especially during critical times for the plant (the seedling stage, the setting of fruit) as lack of water during these times can cause permanent damage to the plant. Check for dryness by inserting your pointer-finger into the soil less mix at the edge of the container. If dryness is found, water. If the mix is still damp, don't water. Typically during the months of July and August, vegetables grown in containers need to be watered every day.
