Planting two seeds will increase your chances of success, because there’s always the possibility that one won’t germinate.
Smaller tomato varieties, such as cherry or grape, are better for upside-down growing. Tomatoes are categorized as indeterminate and determinate. Indeterminate tomatoes are better for upside-down planters because they’re more flexible and won’t produce all their fruit at once, which can weigh down the planter. [4] X Research source
Keep the soil moist, but not soggy, as the sprouts grow. When the top of the soil becomes dry, add more water. [5] X Research source
If you do not have enough light in your home, then use artificial lighting.
Removing the weaker sprout will ensure the healthier plant doesn’t have to compete for nutrients and light.
Don’t let the tomato grow any bigger, otherwise the roots may get damaged when it’s transplanted.
Instead of landscaping material, you can also cover the bottom of the bucket with shredded newspaper, window screen, or disposable coffee filters.
The potting soil will provide a rich and nutrient-dense medium for the tomato, and the vermiculite will help the soil to retain moisture. [12] X Research source
As you plant the tomato into the bucket, be careful not to damage the roots or the stem.
Depending on how high up the top of the bucket is, you may need a chair or step ladder to check the soil and water the plant. If water is dripping through the hole in the bottom of the bucket, you can catch the excess with a pan or drip tray. You can also place another plant underneath the tomato to catch the water.
