Now that you have picked your tomato plant type and gathered your supplies, it’s time to start planting. Follow these easy steps, and you’ll have a lush tomato plant in no time.

Pick your container or pot first and make sure it is a good size for your plant. Most packages will recommend how many seeds should go in any given space.

Step 2:

Next, position your tomato cage or trellis in your container/pot. You want to do this before you add your soil to not damage any of the seeds, or the plant if you’re using a seedling from a nursery.

Step 3:

Now you can add your soil into your container/pot. When choosing your soil you want to pick one that is organically rich, with well-draining and a slightly acidic pH. You will want to choose an all-purpose organic potting mix for your tomatoes. Remember, do not overfill your container/pot. You should fill it about 3/4 the way full, giving your tomatoes room to grow.

Step 4:

Time to add your seeds or plant. Both are very simple to do. To plant seeds, dig out a small hole and pour in the seeds, remembering to follow the instruction on the pack. Then, water thoroughly.

To plant a living plant/seedling, dig a small hole deep enough for the plant’s root system. Cover the roots completely with your soil.

Step 5:

Add fertilizer for a nutritional boost and the best results. Your tomato plant will love to eat as it grows, so give it a fertilizer with lots of phosphorus.

Step 6:

Water your plant thoroughly when it is first growing, it needs a lot of water to thrive; about two inches per week.
