Which Plants Like Potato Water

Potatoes are a staple in many diets around the world, and as a result, their water is sometimes used for irrigation. Potato water is known to have several benefits for plants, including the presence of valuable nutrients and a slight acidity that can aid in their growth. While many plants can benefit from potato water, some are better suited to its specific composition. Let's explore which plants like potato water and how to use it effectively in your garden.

Tomatoes

Tomatoes are the most common plant that benefits greatly from potato water. They prefer a slightly acidic soil with a pH of 6-6.8. Potato water naturally has a pH of around 5.5, making it a great option for maintaining the proper acidity level. The presence of nutrients in potato water, such as potassium, also aid in the growth of tomato plants, leading to larger and healthier crops. Simply use potato water instead of regular water when watering your tomato plants.

Peppers

Peppers are another plant that can benefit from potato water. They are similar to tomatoes in that they prefer a slightly acidic soil, and can especially benefit from the presence of potassium in potato water. As with tomatoes, simply use potato water instead of regular water to give your pepper plants the nutrients and acidity they need to thrive.

Blueberries

Blueberries are a unique plant that require acidic soil to grow properly. They prefer a pH of around 4-5, making potato water an ideal choice for watering them. Additionally, potato water contains magnesium, which can help blueberries produce more flowers and fruit. To give your blueberry bushes the best chance of success, use potato water as a regular part of your watering routine.

Plants to Avoid Using Potato Water On

While potato water can benefit many plants, some are not well-suited to its composition. Plants that prefer alkaline soil, such as herbs like basil, parsley, and cilantro, are not likely to thrive when watered with potato water. Additionally, plants that prefer dry soil, such as succulents and cacti, do not require frequent watering and may be overwatered with potato water.

Ultimately, the plants that will benefit most from potato water are those that prefer slightly acidic soil and require regular watering. By using potato water in your garden, you can give your plants a boost of important nutrients and acidity that can lead to healthier growth and better crops.
