How to Balance pH for Gazania (Treasure Flower): A Comprehensive Guide

Gazania, also known as Treasure Flower, is a beautiful and vibrant flowering plant that adds a burst of color to any garden. However, to ensure healthy growth and optimal blooming, it is crucial to maintain the proper soil pH balance. In this comprehensive guide, we will walk you through the steps to test, adjust, and maintain the ideal pH range for your Gazania plants.

What Is the Ideal pH Range for Gazania (Treasure Flower)?

Gazania plants thrive in slightly acidic to neutral soil, with an ideal pH range between 6.0 and 7.5. When the soil pH falls outside this range, it can affect nutrient availability and lead to various growth issues.

How to Test Soil pH for Gazania (Treasure Flower)

To determine the current pH level of your soil, you can use a home testing kit or send a sample to your local extension service. Home testing kits are readily available at garden centers and online retailers. Follow the instructions provided with the kit to obtain accurate results.

How to Adjust Soil pH for Gazania (Treasure Flower)

If your soil pH is too low (acidic) or too high (alkaline), you can take the following steps to adjust it:

Raising Soil pH (Acidic Soil)

To raise the pH of acidic soil, add dolomitic lime. The general rule of thumb is to add 5 pounds of dolomitic lime per 100 square feet of garden area to raise the pH by one unit. Incorporate the lime into the top 6 inches of soil and water thoroughly.

Lowering Soil pH (Alkaline Soil)

To lower the pH of alkaline soil, add elemental sulfur or a sulfur-containing product. The general guideline is to add 1 pound of elemental sulfur per 100 square feet of garden area to lower the pH by one unit. Mix the sulfur into the top 6 inches of soil and water well.

In addition to adjusting soil pH, you can improve soil structure and nutrient availability by incorporating organic matter, such as compost, peat moss, or well-rotted manure. Mix these amendments into the top 6-8 inches of soil before planting or as a top dressing around established plants.

What Fertilizer to Use for Gazania (Treasure Flower)

Use a balanced, slow-release fertilizer with an NPK ratio of approximately 10-10-10 (nitrogen-phosphorus-potassium). Follow the manufacturer’s recommendations for application rates and timing to avoid over-fertilizing, which can lead to excessive foliage growth and fewer flowers.

How to Water Gazania (Treasure Flower) for Optimal pH Balance

Water your Gazania plants thoroughly, allowing the soil to dry between waterings. Overwatering can lead to root rot and other fungal diseases, which can affect pH levels. If your tap water has a high mineral content, consider using filtered or distilled water to prevent any adverse effects on pH levels.

What Temperature and Sunlight Conditions Are Best for Gazania (Treasure Flower)?

Gazania plants prefer full sun and a moderate temperature range of 60-80°F (15-27°C). Protect your plants from extreme temperatures, as these can stress the plants and potentially affect pH levels.

How Long Does It Take to Balance pH for Gazania (Treasure Flower)?

The time required to balance soil pH for Gazania plants depends on the initial pH level and the chosen amendment. Lime and sulfur can take several weeks to months to fully react with the soil and stabilize the pH. Monitor the soil pH every 4-6 weeks and make adjustments as needed.
