Calcitic limestone raises overly acidic soil toward a healthier pH range while adding slow, steady calcium for stronger roots and sturdier new growth. It’s important because pH controls nutrient uptake, and it’s unique because it buffers the root zone gradually instead of acting like a fast, temporary calcium boost.

Canadian sphagnum peat moss is important because it holds moisture evenly while still supporting air spaces that roots need for oxygen, which makes watering and nutrient uptake more consistent. It is unique because it naturally trends acidic and acts more like a moisture-and-structure foundation than a nutrient source, so it changes root-zone balance in ways other base ingredients do not.

Dolomitic limestone is both a gentle pH buffer and a slow source of calcium and magnesium, which is important because pH stability controls how reliably roots can access nutrients. It’s unique because it supports magnesium at the same time it neutralizes excess acidity, helping you avoid the common situation where pH improves but growth still struggles due to a weak calcium-magnesium foundation.

Perlite is important because it increases root-zone oxygen and improves drainage, helping roots stay healthy and active; it’s unique because its main benefit is physical structure and airflow—not nutrients or moisture storage—so it fixes “too wet and compact” root problems in a simple, predictable way.

A starter charge usually lasts until the plant’s roots and growth rate outpace the small pre-mixed nutrient supply, which is why it’s ideal for early establishment but not long-term feeding. It’s unique because it’s intentionally mild and temporary, acting as a gentle bridge for seedlings and transplants before a regular nutrition routine begins.
