Arber Organic Soil & Root Food 4oz

Grow stronger roots, naturally organic.

Organic. Plant-Based. Arber Organic Soil & Root Food 4oz is a concentrated, soil-first tonic crafted to fortify roots, energize microbial life, and improve nutrient availability across containers, raised beds, and in-ground plantings. This gentle, low-odor formula feeds your soil so plants can build stronger, denser root systems, bounce back from stress, and deliver vigorous top growth and harvests. Ideal for vegetables, herbs, flowers, houseplants, and grain crops, helping plants establish quickly and support abundant production of seeds when grown to maturity. Use as part of your regular watering routine or during key moments like transplanting, pruning, or after heat/cold spells. Safe for home use and designed to complement organic gardening practices, Arber’s soil & root food helps loosen compacted soils, improves water and nutrient uptake, and encourages resilient, high-performing plants without harsh synthetics—perfect for gardeners seeking dependable results in a simple, ready-to-dilute format.
