Lambert Shrimp and Peat Moss Compost is a pH adjusted soil amendment designed to condition garden soil for flower beds and vegetable gardens. This versatile soil conditioner brings marine and peat-based inputs together to support better soil structure in common outdoor planting areas.
This blend is built from Canadian sphagnum peat moss, compost, and shrimp meal, then balanced with dolomitic limestone and calcitic limestone. Those core components create a pH adjusted foundation while delivering a source of organic matter that helps improve the overall feel and workability of garden soil. With compost and shrimp meal included, it’s also described as rich in nutrients that promote plant growth, making it a practical choice when you want more than a basic soil builder.
Lambert Shrimp and Peat Moss Compost is also valued for moisture performance. As a soil amendment that improves water retention, it supports more even moisture conditions in beds and garden spaces where soil can dry out quickly in warm or windy weather. Better water retention can help reduce plant stress and support steadier early development, especially when you’re establishing new plantings and want a more consistent root-zone environment.
For outdoor versatility, this pH adjusted soil amendment is recommended across several common yard and garden projects. It’s suited to gardens and flowers when building or refreshing planting spaces, and it’s also positioned for lawn maintenance where soil quality and moisture handling matter. If you’re working around trees and shrubs, it’s a straightforward soil conditioner option for improving the soil environment in landscape areas that benefit from added organic matter and better moisture management.
This product fits well into a complete fertilization program for gardeners who want a simple, ingredient-forward amendment that supports plant growth without complicating the rest of their routine. It’s a good fit for growers looking for a soil amendment and soil conditioner made with Canadian sphagnum peat moss, compost, and shrimp meal for flower beds, vegetable gardens, lawn maintenance, and planting areas around trees and shrubs.
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.
Compost supports plant growth by building a healthier root zone, improving water retention and drainage at the same time, and helping nutrients stay available in a steadier, more buffered way. It’s unique because it’s a finished, stabilized organic material that works mainly by improving soil structure and biology, not by delivering a fast “spike” like many other organic inputs.
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.
Yes, shrimp meal can be good for plants because it slowly releases nitrogen while feeding beneficial root-zone microbes through its shell material, which can support steadier growth and resilience. It’s unique because it influences soil biology as much as nutrition, but it works best when used moderately so you don’t trigger excess nitrogen or low-oxygen root stress.
