Q: How should I choose a water bottle for my Petomato™?

A: Any moderately sized, plastic bottle will work for your Petomato™. Remember to make a sunshade for the roots, no mater which bottle you decide to use.

Q: Should I use fertilizer when planting my Petomato™?

A: No, only add fertilizer to the water after your plant has germinated and you can see growth.

Q: What is the purpose of the sand?

A: The sand protects the seeds when they are first planted and it anchors the sprouts as they begin to grow.

Q: Can the seeds get wet when planting my Petomato™?

A: After you put the sand on top of the seeds, carefully add three drops of water to the top of your Petomato™ to activate the filter that will draw up water from the bottle.

Q: Is Petomato eco-friendly?

A: Yes, Petomato™ grows in a recycled water bottle, which reduces waste.


Q: How much water should I put in my Petomato™ bottle?

A: The bottle should be filled to the top.

Q: As my Petomato is growing, how often should I refill the water?

A: Refill the water bottle as often as necessary. When your Petomato™ begins to grow, it will drink a lot of water and may need to be refilled daily.


Q: What is germination?

A: Germination is the process by which plants emerge from seeds and begin to grow.

Q: How long does it take for tomatoes to germinate?

A: Seeds usually germinate in 7-10 days after planting. See “Care & Growth Instructions” here.


Q: What is culling?

A: Culling is the process of removing the offshoots or undesirable sprouts of an established plant.

Q: If more than one sprout begins to grow, can I keep all of them?

A: The Petomato™ is best when only the one best sprout is allowed to grow. Multiple sprouts take up too much room and the plant that grows is smaller and yields less fruit.

Q: When I was changing the water, I removed my Petomato™ tube and some of the roots ripped off. What should I do?

A: If there are any roots remaining, carefully put the tube back into the water bottle and continue growing. If no roots remain, your Petomato™ may not survive.


Q: What is fertilizer?

A: Fertilizer is included with your Petomato™ and it provides nutrients that would normally be present if your plant was growing in soil.

Q: How much fertilizer should I use when I refill my water bottle?

A: Add one spoonful of fertilizer to the water bottle for every four ounces of water when changing the water weekly. If your bottle is 16 ounces, add four level spoonfuls of fertilizer. The spoon is provided with Petomato™. Please refer to the “Healthy & Happy” page here to trouble-shooting problems.


Q: How should I choose where to grow my Petomato™?

A: You should grow you Petomato™ in any location that receives adequate sunlight throughout the day.

Q: Why do I need to wrap the bottle with paper?

A: Roots normally grow underground, so they thrive in an environment with little or no sunlight. This paper is called a sunshade.

Q: How to I make a sunshade?

A: Measure the height of your water bottle. Cut a piece of paper to that measurement. Wrap the paper around the bottle and secure with two rubber bands or a piece of tape. See how to make one here!


Q: What is pollination?

A: Pollination is the process by which pollen is transferred in the reproduction of plants, enabling fertilization.

Q: How do I pollinate the flower buds?

A: Using the tip of one finger, in a random order, touch each of the buds at least three times. This cross-pollinates the flowers, doing the job that bees would do if the plants were growing outside.

Q: What will happen to to my Petomato™ if I do not pollinate?

A: Your Petomato™ plant will not produce tomatoes or habañero peppers.


Please refer to the “Healthy & Happy” page for more information and trouble-shooting help.

Q: Why are my basil leaves turning yellow?

A: If the leaves are turning yellow, your Petomato™ is either receiving too much fertilizer or not enough water. Be sure to keep the water filled and limit the addition of the fertilizer until the leaves become green again.

Q: What should I do if algae grows in my water bottle?

A: If algea begins to grow in your water bottle, discard the bottle and plant your Petomato™ in a different recycled bottle.

Q: What should I do if I see what scales in the water?

A: This is a plant disease and you should change the water Petomato™ immediately if you see this occur.


Q: What elements of Petomato™ are edible?

A: The fruit of the tomato plant, basil leaves and habañero peppers are edible and very enjoyable to eat.

Please use caution when eating and handling habañero peppers. Do not touch your eyes before washing your hands thoroughly after handling them. Parents should supervise children’s consumption and handling of habañero peppers.

Q: What elements of Petomato™ are edible?

A: Do not eat seeds, sand, fertilizer. These elements of Petomato™ are NOT edible for human consumption.

Q: Can you guarantee that Petomato™ will grow food?

A: Unfortunately, we cannot guarantee that Petomato™ will grow food. Nature doesn’t always cooperate, but if you follow the instructions, your Petomato™ will have the best chances of producing fruit.

Purchase & Shipping

Q: Is your product available outside of the Unites States?

A: The regulation of seeds and plants is under the USDA, United States Department of Agriculture. Transportation of seeds and plants outside of the USA is not allowed without an inspection by the USDA.  Please do not send Petomato as a gift to anyone living outside of the USA.  Non-native plants can be disruptive to ecosystems.
