Roots Healthy Start Advanced 3-4-3 Natural Granular Fertilizer — 25 lb Bag, Organic NPK & Beneficial Microbes

Roots Healthy Start Advanced 3-4-3 is a natural granular fertilizer with beneficial rhizosphere bacteria that slowly releases nutrients and builds organic matter for gardens, beds, containers and new turf.

Designed as a versatile soil amendment, this 25 lb bag supplies an NPK ratio of 3-4-3 derived from organic sources and includes potassium sulfate for immediately available potassium plus a small sulfur boost. The formula blends kelp meal, humic acids and microbial inoculants so the product functions both as a nutrient source and as a biological soil enhancer. Manufactured as an insoluble granule, it biodegrades in the soil to feed plants over time while contributing organic content to depleted planting sites.

How should I use it when planting new shrubs, trees or bulbs?

Apply the granules at planting to improve root-zone nutrient availability and to seed beneficial microbes into the root environment. Mix into backfill or place in the planting hole following package rate guidance to avoid over-concentration near roots. For bulbs, work it into the soil surface above the bulb or mix lightly with the potting medium.

• Mix into backfill or potting mix at recommended rates
• Broadcast and rake into beds before planting for even distribution
• Avoid placing dense clumps directly against delicate roots

Can I use this product for lawn establishment or sod?

Yes — the product is suitable for grass seedings and sod installation because it supplies slow-release nitrogen and immediate potassium while improving soil organic matter. Apply prior to seeding or under sod to give young grass balanced nutrition and beneficial microbes for root development. For established turf, use as a top-dressing according to the dosage instructions.

• Spread evenly before seeding or under sod to prime the soil
• Top-dress established lawns at lower rates to boost soil health
• Supports root systems with organic nitrogen and potassium sulfate

What makes this fertilizer different from simple synthetic feeds?

Instead of only supplying soluble salts, Roots Healthy Start Advanced is formulated from organic nutrient sources and contains rhizosphere bacteria that help recreate a living soil environment. The granules are insoluble and release nutrients as they biodegrade, adding organic matter as well as fertility. Potassium sulfate provides a portion of immediately available potassium, while kelp meal and humic acids supply micronutrients and biological stimulants.

• Organic NPK sources for gradual nutrient release
• Beneficial microbes to enhance soil biology and nutrient cycling
• Humic acids and kelp meal for improved soil structure and micronutrients

How do I apply it to containers, potted plants, and established beds?

For containers, blend into the potting mix before planting or apply as a top dressing and water in lightly. In established beds, broadcast and rake the granules into the soil surface or use a light top-dress, then water to move nutrients into the root zone. Follow product label rates for specific application volumes based on plant size and soil condition.

• Mix into potting medium for new container plantings
• Top-dress containers and beds and water to activate
• Adjust rate for plant size and existing soil fertility

Who is this for: Home gardeners, landscapers and hobby growers who want a natural, slow-release granular fertilizer that also improves soil biology. It fits users preparing garden beds, planting bulbs, establishing turf, filling containers, or refreshing established planting areas and who prefer organic-based nutrient sources with added beneficial microbes.
