How to Balance pH for Meadowsweet Plants

Balancing the pH for Meadowsweet (Filipendula ulmaria) is crucial for optimal plant growth and health. This guide will provide you with a comprehensive understanding of the key factors to consider, including soil pH, compost, temperature, harvesting, and feeding, to help you achieve the perfect pH balance for your Meadowsweet plants.

Soil pH for Meadowsweet

Meadowsweet thrives in a neutral to alkaline soil pH, typically ranging from 6.0 to 8.0. If your soil is too acidic, you can add lime to raise the pH. The amount of lime needed will depend on your soil type and current pH level. A soil test can help determine if lime is needed and how much to add. Generally, it’s recommended to add about 5-10 pounds of lime per 100 square feet of garden area, but this can vary.

Compost for Meadowsweet

Adding compost can increase the nutrient content of Meadowsweet, but it may not significantly lower the pH. Compost is beneficial for overall plant health, providing slow-release nutrients and improving soil structure.

Temperature and Meadowsweet

Extracting phenols from Meadowsweet at temperatures above 90 °C yields extracts rich in phenols, quercetin, and salicylic acid, with good color and a relatively low proportion of tannins in the extracts. This suggests that higher temperatures may be beneficial for extracting and utilizing these compounds, which could potentially influence pH balance.

Harvesting Meadowsweet

Meadowsweet has a long history as a folk remedy for digestive problems, including dyspepsia, colic, and diarrhea. Harvesting Meadowsweet at the right time can help ensure optimal pH balance and medicinal properties. Generally, it’s best to harvest Meadowsweet in the summer and autumn, just before or as the flowers begin to open.

Feeding Meadowsweet

For horses, it’s suggested to use between 20 – 30 grams of Meadowsweet daily, ideally splitting the daily amount between two feeds. This can help maintain normal pH balance and support gut health.

Home Remedies for Balancing pH

In addition to the above methods, there are several home remedies you can try to balance the pH for your Meadowsweet plants:

  1. Baking Soda: Mix 1 tablespoon of baking soda per 1 gallon of water and apply it to the soil around your Meadowsweet plants. This can help raise the pH.

  2. Vinegar: Mix 1 part vinegar with 10 parts water and apply it to the soil around your Meadowsweet plants. This can help lower the pH.

  3. Coffee Grounds: Sprinkle used coffee grounds around the base of your Meadowsweet plants. The acidity in the coffee grounds can help lower the soil pH.

  4. Eggshells: Crush eggshells and mix them into the soil around your Meadowsweet plants. The calcium in the eggshells can help raise the pH.

  5. Peat Moss: Add peat moss to your soil to help lower the pH. Use about 2-4 inches of peat moss per square foot of garden area.

Remember to monitor the pH regularly and adjust your home remedies accordingly. It may take several applications over the course of a few weeks to achieve the desired pH balance for your Meadowsweet plants.

Temperature and Watering Requirements

Meadowsweet prefers a temperature range of 60-75°F (15-24°C) and moist, well-drained soil. Water your Meadowsweet plants regularly, keeping the soil consistently moist but not waterlogged.


Balancing the pH for Meadowsweet is essential for the plant’s overall health and growth. By understanding the ideal soil pH, incorporating compost, considering temperature, timing harvests, and utilizing home remedies, you can create the perfect growing conditions for your Meadowsweet plants. Remember to monitor the pH regularly and adjust your approach as needed to maintain the optimal pH balance.
