First of all, you need an adequate self-watering bucket. Not all self-watering containers are suitable for growing tomato. It is widely known that tomato is a highly delicate fruit, thus, an appropriate self-watering container is compulsory for growing tomato successfully.

Here you will find the best self-watering containers for growing tomatoes.

You could either purchase or make your self-watering bucket. If you want to create your own,  the first step requires that you make a wick out of a used bottle, and cut it to about a quarter of the height of the pot you are using. Using a sharp object, poke holes in the sides of the bottom of your wick.

Afterward, make a pipe out of any PVC pipes, hoses, or copper pipes you have around the house. If you don’t have any, just purchase a PVC pipe. Then, right below your wick, drill a hole in your bucket to prevent flooding and make a barrier by pressing it into the inner center and sides of your wick using window screen or recyclable shopping bags.

Now, take the pipe and place it on the side of the wick. To keep your pipe and wick in place, place rocks all over your wick. Once the rocks are at level with the top of the wick, press the barrier all over them to keep the rocks from mixing with soil

Pack your soil tightly inside the wick and then place your tomato plant inside your self-watering pot. Fill the pot with soil making sure that your tomato plant is buried deep inside your self-watering pot.

2. Add support

For growing tomato in self-watering buckets, it is better to support your plants with tomato cage rather than sticks. An ideal tomato cage measures 14-1/2″ wide by 21-1/2″ deep by 30″ high with 8″ legs. A cage of this size will definitely provide sufficient support for average-size plants.

However, tomato plants may grow to reach a 4 feet height.  It’s a good idea to add a center stake at planting time for extra support. If your tomato starts falling on the ground, you could order a cage extension over here.

3. Sunlight exposure

For growing tomato in self-watering buckets successfully, you need to expose your plant to a lot of sunlight. Place your self-watering container in a place where it can get healthy doses of sunlight every day. Balconies and windows are ideal locations for full sun exposure.

However, if you live in an area where it is cloudy and rains most days,  you can grow your tomato in partial shade. Just don’t let the rain gets to your pot to prevent mold.

4.  Watering

While you are at home and you have a free time, you should do the watering yourself. Assign the watering task to your self-watering container when you are gone for work or when you are busy.

Tomato needs regular doses of water.  It is best to give them these doses in moderation every morning. However, be careful of overwatering.  Although the drain hole on the bottom of your pot can help prevent the accumulation of excess water, overwatering can lead to root rot.

5. Feeding you plant
