Stuffed, baked, fried and even raw, zucchini is delicious and healthy to eat. Eating zucchini that you grew is even more enjoyable. Zucchini is one of many vegetables that will grow in containers. You can grow zucchini without having a yard or a garden plot to enjoy during the summer. A container with proper drainage and soil will have you growing the perfect zucchini plants.
Choosing Container Size
Zucchini forms a vine with male and female flowers. The females produce the actual zucchini that you eat. They have a deep root system. It's important to have plenty of container space to grow the vines and to support the roots. Start a seedling in a 5-gallon bucket. As the plant grows, transplant to an 18-gallon bucket. Usually, you can expect to transplant around the time you see the buds for the first flowers. You can start a seedling in an 18-gallon bucket if you're not comfortable transplanting for container gardening.
Drill several small holes 1/2 inch from the base of the zucchini-growing container. Do this all the way around the container. Drill three large holes in the bottom of the container. Zucchini requires a great deal of water. It is possible to overwater with improper drainage. The additional drainage holes will prevent root rot and allow the lower soil areas of the container to receive proper amounts of oxygen.
Rocks or Pebbles
Fill the bottom 1/4 of the container with medium-sized rocks or pebbles. Place the rocks or pebbles loosely to allow plenty of room around them. This area will serve as additional drainage for the zucchini roots.
The second layer to getting your zucchini growing containers ready for planting is mulch. Use large mulch pieces, such as pine bark, above the rocks or pebbles you added to the first layer. Only a thin layer is needed. Just cover the first layer of the zucchini growing container's rocks.
Mix pumice and vegetable starter food in with the soil. You can also add Styrofoam crumbles to the soil. Stir the mixture well. Follow the directions on the vegetable starter food to mix it in the right proportions. Large containers are at risk for improper oxygen levels to the roots and soil fungi growth. Mixing the pumice or crumbles in the soil will keep it from becoming compact and tight around the zucchini roots to assure healthier plants.
Fill the zucchini growing container 3/4 full with the potting soil mixture. Use a garden trowel to dig a hole 1 inch deeper than the seedling's height. Your zucchini growing container is now ready to plant your zucchini seedling.
