One of the ways to classify cucumbers is on the basis of how they grow. In this case, two of the most common options are vining and bush. Vining cucumber is the more common choice if you want a plant to grow outdoors. Because it crawls, you need to provide trellis to support its extensive growth. If you intend to grow the plant indoors and in containers, opt for the bush cucumber. It is more compact, and hence, making it perfect if you have space limitations. Even if they are small, they can have abundant yield, especially if you pay attention to proper care and maintenance.

Planting and Growing Conditions

To start growing cucumbers, the first thing that you need to do is to purchase healthy seeds. As much as possible, opt for hybrid seeds that will not need pollination. This is important because the plant will be staying indoors, and hence, pollination can be a bit of a challenge. See to it as well that it is a dwarf variety, which will allow you to save space.

Next, choose your container. Even if you are planting a bush or dwarf variety of cucumber, it is still best to use a large pot. This will eliminate the need to transplant once the plant grows larger. A hanging pot will also be a good choice. The pot can be made from any material. The important thing is for it to have drainage holes at the bottom, which will prevent the water from being stuck.

At the bottom of the pot, place a thin layer or pebbles or clay shards. This will help to improve the drainage, and hence, will make the roots less prone to diseases. Fill the container with your choice of potting soil. As much as possible, use equal parts of compost and soil. The addition of organic matter will improve the nutrients in the soil, which can help speed up the germination of the seeds.

Create holes using your finger. Fill each hole with four to five cucumber seeds. See to it that the hole has a depth of at least half an inch. To add, make sure as well to maintain the right space in between the holes so that that they will not end up crowding the pot. After sowing the seeds, water it, but make sure that it will not be soggy.
