When a plant is covered and tied over a plastic bag, the plant eventually dies due to depletion of starch. The plant needs carbon dioxide and water to produce food in the sunlight through the process of photosynthesis with the help of chlorophyll. In the absence of water, starch is lost to the atmosphere.
In the case of plants that are covered with plastic bags, it is not the plastic that is the problem, but rather the lack of oxygen. Oxygen is necessary for the photosynthetic process to take place. Without oxygen, there is no way to convert starch to sugar, which is what plants need in order to grow and reproduce.
This is why plants are often covered in plastic to protect them from the harsh environment of the soil.

How do you plant in a Ziplock bag?
The beans should be visible on the side of the window where your child will be watching them grow. After 24 hours, remove the bags and place them in the refrigerator for at least 4 hours to allow the moisture to evaporate. The seeds should be soft and pliable, but not mushy.
If they are too dry, add a little water to moisten them. You may need to add more than one bag at a time, depending on how much moisture is left in your seeds. After 4-6 hours of refrigeration, you can harvest your beans.
Can you grow vegetables in plastic bags?
Plastic grow bags are best-suited to growing single plants of larger vegetable varieties such as tomatoes and peppers. When there is 2 feet of soil in the bag, fill a plastic bag with it. The bag should be placed on the ground with the top of the bag level with plants in mind. Place the pot in a warm, dark place and allow it to grow for a few weeks.
When the plants are ready to harvest, remove the plant from its bag and place it on a cutting board or other flat surface. Place the cuttings into a large pot and cover them with a thin layer of compost. Allow the compost to soak in for at least a week, or until the roots have fully developed. The roots will then be ready for transplanting into the new pot.
How long can a plant survive in a plastic bag?
Inside a plastic bag, your plant will be able to survive for months without any water at all. This is because most of the water you normally apply to your plants is lost to transpiration and evaporation: inside a sealed bag, the humidity inside the bag is much higher than the outside air.
Can plants get sunlight through plastic?
Do not return your plant to full sunlight. It’s best to find a temporary location with indirect or artificial light because sunlight hitting the plastic may cause high temperatures in the bag and hurt your plant. The plastic bag doesn’t penetrate the plant tissue because air goes through it.
Can plants be covered with plastic?
During a short cold snap, the warmth may be enough to keep a plant from freezing. When protecting plants in a freeze, you can place plastic over the sheets or blankets to keep the warmth in. Never cover a plant with just plastic, however, as the heat from the plastic can cause the plant to overheat and die.
Will a seed begin to grow in a plastic bag with or without water?
It can be difficult for small seedlings to grow in the garden bed since they may be washed away by the rain. Growing the seeds in advance inside a plastic bag prevents this from happening. If you want to grow your seeds indoors, you’ll need a container with a drainage hole. You’ll also need an air-tight container, such as a glass jar, to keep the soil moist.
If you don’t have one of these containers handy, use a large pot with holes drilled in it. The holes should be at least 1/2-inch in diameter and 3 inches deep. Fill the jar with soil and place it on top of the container. Cover the hole with plastic wrap and let it sit for a few days. After a week or so, remove the plastic and check to make sure that the holes are still in good shape.
They should still be large enough to allow air to pass through them, but not so large that they block the air flow. When you’re ready to plant, place the pot in a sunny spot and cover it with more plastic. Let it grow until it reaches a height of about 3 feet, then remove it from the sun and allow it to dry out for several days before transplanting it into a new pot.
