Seedlings can be started in plastic containers of any type, but they are not natural or biodegradable. Many people suggest saving yogurt cups and other small containers, but natural items that can be planted directly into the ground are a much better choice. They will gradually decompose, and the growing plants will feed off of the decomposing material. Use these natural starter containers for seedlings, and save money over larger plants from your local garden center. Seeds are considerably cheaper, and you will have many more choices for growing fruits, veggies, flowers and more.
Use Eggshells as Planters
Eggshells are some of the best natural starter containers for seedlings. When preparing eggs, use a butter knife to gently tap and crack open the tops. Pour out the contents, and carefully wash the shells using hot soapy water. Gently fill the eggshells with planting medium that has been infused with seeds. Keep the natural starter containers in a warm location until the seeds develop into seedlings. After outdoor temperatures are ideal, take the seedlings outside for about 30 minutes at a time to strengthen the stems. Egg cartons are fantastic carriers for natural eggshell containers. After the stems are strong, plant the seedlings and the natural containers directly into well worked soil. You will save money over peat pots and other planters, and the plants will grow and thrive.
Citrus Halves are Excellent Starters for Seedlings
If you enjoy oranges, lemons and other citrus fruits, do not throw away the peels. Do not destroy them either. When kept intact they make fantastic natural containers for seedlings. Slice all of the way through the fruit, and use a grapefruit fork or a spoon to remove the wedges. Fill the empty halves with rich organic soil, and sew seeds in the natural containers according to packet directions. After they have developed into strong seedlings, plant the natural containers in the ground. They will nourish the plants, and nothing will go to waste.
Use Avocado Skins as Natural Planters
Avocado skins are quite tough, and when removed without a tear, they make fantastic natural planters for seedlings. Simply cut off the smaller end of the avocado, and carefully scoop out the fruit along with the pit. Fill them with rich organic soil, and plant seeds of your choice according to packet directions. After the seedlings sprout and become hardened after placing them outside each day, the natural planters can be placed directly in the ground. The developing plants will gain sustenance from the remains of the avocados, and with continual watering and care, they will beautifully grow and thrive.
