Which Plants Can Be Grown in Bottles?
To start with, all plastic bottles are not good for growing plants. Similarly, not all plants are grown in plastic bottles. To help you on which plants you can grow in plastic bottles, we will highlight the plants below and how you can grow them.
Basils can be grown indoors and outdoors. If you decide to grow basils indoors in a plastic bottle, put the basil cuttings in water for a few days until roots start to appear.
Transfer the cuttings to the well-prepared plastic bottle, which must be filled with the best potting soil. Place the plant in a sunny spot in your home.
Parsley is best grown in small spaces with partial sunlight. These features make parsley perfect to be planted in a plastic container. The soil in the plastic container should be moist and wet. Remember not to over-water your parsley plant.
Parsley is quite useful as herbs and can be added to our dishes and known for its refreshing taste. Parsleys are best planted as seeds and thrive better in winter.
Strawberries can be planted during any season, and most importantly, they can be grown in a plastic container. If you can’t find a sunny spot in your home to place your strawberry plant, you can set it under artificial light.
When your strawberry plants start to produce fruits, make sure to harvest them immediately to make space for new fruits.
If you are a fan of Oregano plants, well, here is some good news, they can be grown in a plastic container. You can start by growing Oregano seeds or store-bought Oregano cuttings.
Like basil, the Oregon plant should be placed in water for a few days before being transferred to a plastic bottle.
Just like Oregon and basil. Rosemary can be planted in a plastic bottle. The only difference is that rosemary thrives in an acidic environment; thus, it is advised that some sand be added at the bottom of the bottle.
Remember to water the plant regularly, as dry soil might impede the growth of the plant.
Only small peppers are suitable to be planted in a plastic bottle as big peppers require more space or, at the very least, a big container of a plastic bottle.
Pepper is a sun-loving plant; this follows that your peppers require at the very least 8 hours of sunlight per day. Gardeners recommend that you start with pepper cuttings instead of the seeds; this will save you a lot of time.
Spinach can also be planted in plastic bottles. Just make sure that the bottle is at least 8+ inches of height. Spinach doesn’t necessarily need sunlight; you can place it in a shady part of the house.
Spinach is both an indoor and outdoor plant. Fill the container with good potting soil, sow a few spinach seeds, and regularly remember water.
