Types of Pots for Growing Lettuce

When you want to grow lettuce, it is essential that you select the best container. Lettuce can grow next to other plants, but it does need soil that is at least six inches in depth. This ensures that your lettuce will grow the best possible. 

Most varieties of lettuce have shallow roots. This means they grow best in shallow and long containers. A perfect pot is one that is a minimum of 10 to 12 inches in diameter. The larger the variety of lettuce means that you need a large container. 

When looking for a pot for your lettuce, the material does not matter too much. You can select clay, terracotta, or plastic. Plastic is a lightweight material that makes it easy to move wherever you want it, even when it is full of soil. 

What is important when looking for a container for your lettuce is that it has drainage holes at the bottom of it. If your pot does not have drainage holes, your lettuce plants may become unhealthy and full of water. If the pot you want does not have drainage holes, you can drill holes in it. 

In addition, you want to ensure that the soul is moist consistently. You do not want the soil to be wet. When the roots of your lettuce are wet, it may cause your plants not to grow. On the other hand, you want your lettuce to be loose, and you want to be able to work it. You can mix the soil with sand to help lighten the soil.

If you want a container that is permeable, you should consider one that is made from clay. When you grow lettuce in a clay pot, it allows the water to evaporate. This evaporator process helps to prevent the lettuce roots from being soggy. 

When you plant your lettuce, you want to ensure that the container is big enough to hold whichever lettuce variety you want to grow. If you select a pot that is too small, the place may become pot-bound. You also want to ensure that your lettuce receives sun. It would be best if you placed your lettuce pot so that it receives the midday sun because it is most intense.
