Soil pH Secrets for Happy Edibles


Are you dreaming of a garden paradise but unsure about your soil's pH? No worries! At Ironstone, we're here to help your favourite fruit trees and plants thrive, no matter their pH preferences. Let's explore some tips for a healthy, happy garden.
Soil pH measures how acidic or alkaline your soil is, ranging from 0 (very acidic) to 14 (very alkaline), with 7 being neutral. Most plants, including fruit trees, prefer slightly acidic to neutral soils, around pH 6.0 to 7.0.
Fruit Tree pH Preferences
Figs: Thrive in pH 6.0 to 6.5, preferring slightly acidic to neutral soils.
Citrus Trees: Prefer pH 6.0 to 7.0, ideal for good growth and fruit production.
Pomegranates: Also do well in pH 6.0 to 7.0.
Kumquats: Thrive in pH 6.0 to 7.0, similar to citrus trees.
Berries: Need more acidic soils, around pH 4.5 to 5.5.
Jaboticaba, Davidson Plum, and Finger Lime: Prefer slightly acidic to neutral soils.
Add compost, peat moss, or well-rotted manure to improve soil structure and balance pH.
Use sulphur or aluminium sulphate to lower pH levels. Follow the instructions on the packaging carefully.
Add pine needles or Casuarina needle-fall (like River Sheoak, Swamp Sheoak, Black Sheoak, and Forest Sheoak from our collection). These materials help maintain soil acidity over time and conserve water.
Regularly test your soil to monitor pH levels and make adjustments as needed.
Bore water irrigation can significantly affect your soil's pH. Bore water often has high levels of dissolved minerals and can be alkaline. Over time, using bore water for irrigation can raise your soil's pH, making it more alkaline. This can lead to nutrient deficiencies and affect plant growth.
Plants often give off clues if the soil pH is not suitable for them. Here are some signs to watch for:
Yellowing Leaves: If the leaves are yellowing but the veins remain green, it could indicate iron chlorosis, often caused by too high a pH.
Stunted Growth: Plants growing slowly or not reaching their usual size may be struggling with the wrong pH.
Poor Fruit Production: If your fruit trees are not producing as much fruit as expected, the soil pH could be off.
Leaf Drop: If your plants are dropping leaves out of season, it could be a sign of pH imbalance.
Wilting: Wilting leaves, even when the soil is moist, might suggest a pH issue.
Balancing your soil pH is key to a successful garden. We're here to help you create a garden full of healthy, productive plants. Visit us at Ironstone to check out our plants and get more gardening tips.
