Beets do not like to be transplanted so pick the desired pot and sow seeds 1-4 inches deep and 2-3 inches apart. But you can sow more seeds than the container size because when they germinate and reach a significant height, thin the seedlings. 

Seeds will germinate between 7 and 15 days depending on the conditions and your selected type. Maintain moisture content in the soil, water your soil regularly or add mulch it also helps in the retention of moisture.

Carrots:

Water when soil seems to dry. To promote growth fertilize the pot after two or three weeks but avoid high nitrogen fertilizers, as they encourage only aerial parts, vegetables look healthy in appearance but when you harvest the result is the opposite. 

If you notice that carrots push out of the ground add a bit more potting mix to cover them. Most varieties of carrots get mature within two to three months of the seedling and some may take more. 

Eggplant:

If you grow tomatoes in pots it’s not tough for you to have eggplant. Select a three-gallon pot and place one plant per pot.

Feed your plants properly and avoid the use of fertilizers that contain an excess of nitrogen. Keep eye on the soil temperature, and provide mulch to your plants as it helps in temperature regulation as well as retaining soil moisture.

Tips for Containers:

  • Containers come in variant shapes and sizes. You can use anything from your home as a container unless it has a proper drainage system or you can make holes by yourself. Following things like toys, plastic bottles, bathtubs, furniture, and many more can be used as containers.
  • Try to avoid wooden containers as they are subjected to rot. But if you want to use them, paint them from the inside or apply sealing wax as it may add to the life of the container. Avoid treated wooden containers. They can add toxic chemicals into the soil that can damage plant roots or you may get even worse results.
  • Leached water from containers leaves marks on the floor or wood, so it’s a good idea to place something below the containers for the collection of excess water.
  • Large containers when fill with soil and plants they become heavy and difficult to move around. So first keep your container in a spot where there is no need for displacement means plants get every required thing. Or if there is a need for movement using a plant caddy.
  • If you have no idea about the size of the container, select bigger than the one with the bigger size. Because small-sized containers hold less soil and need to be watered and fertilized more frequently than larger ones, moreover by using a large containers you also have no need to transplant your plants.
