Customer Questions & Answers
-
Question:
What is Roots Organics Elemental Supplement 20% Calcium 4% Magnesium Fertilizer used for?
Answer: Roots Organics Elemental Supplement is primarily used to boost calcium and magnesium levels in soil, essential for optimal plant health. Calcium promotes cell wall structure, while magnesium is crucial for photosynthesis. This makes it ideal for gardeners seeking to enhance the growth of vegetables and flowering plants. For best results, mix it into your soil or apply it as a side dress during the growing season. -
Question:
How should I apply the Roots Organics Elemental Supplement fertilizer?
Answer: Application of this fertilizer can be done by mixing it into your garden soil before planting or as a top dressing around established plants. It can also be dissolved in water for a liquid feed. It’s particularly effective when used on calcium-deficient crops such as tomatoes, peppers, and leafy greens. Always follow the recommended application rates for best results, ensuring your plants receive the right amount without over-fertilizing. -
Question:
Is this fertilizer organic?
Answer: Yes, Roots Organics products are designed to be organic. This fertilizer contains natural ingredients that help cultivate a healthy soil environment. Being organic means it supports sustainable gardening practices and enhances microbial life in the soil, contributing to long-term plant health. If you prioritize organic gardening, this supplement is a great choice for enriching your soil without synthetic chemicals. -
Question:
Can I use this fertilizer for indoor plants?
Answer: Absolutely! Roots Organics Elemental Supplement is safe for indoor plants as well. Just be mindful of the application rates, as indoor plants often require less fertilizer than outdoor ones due to their limited growing space. Use it when transplanting or as a liquid feed to help indoor flowering and foliage plants thrive. It’s a practical solution to ensure your indoor garden receives the necessary nutrients. -
Question:
What are the signs of calcium or magnesium deficiency in plants?
Answer: Common signs of calcium deficiency include blossom end rot in tomatoes and curled leaves, while magnesium deficiency often presents as yellowing between leaf veins. If you notice these issues, it may indicate a need for an amendment like Roots Organics Elemental Supplement. By applying this fertilizer, you can help rectify these deficiencies and restore the health of your plants, leading to improved yield and vitality. -
Question:
What types of plants benefit most from this fertilizer?
Answer: This fertilizer is particularly beneficial for flowering plants and vegetables that demand higher calcium and magnesium levels. Plants such as tomatoes, peppers, and brassicas flourish with these nutrients, as both minerals play critical roles in plant metabolism and growth. By incorporating it into your gardening routine, you’ll not only improve plant health but also boost flowering and fruiting potential. -
Question:
How often should I use Roots Organics Elemental Supplement?
Answer: It's recommended to apply Roots Organics Elemental Supplement every 4 to 6 weeks during the growing season. This regular feeding helps maintain adequate nutrient levels in the soil, which is essential for continuous plant growth. Adjust frequency based on plant performance and specific needs; more demanding crops might require more frequent applications. Regular monitoring will ensure optimal results throughout the season. -
Question:
Does this fertilizer work with hydroponic systems?
Answer: Roots Organics Elemental Supplement can be used in hydroponic systems with caution, as the concentration of nutrients needs to be carefully monitored. While it provides essential calcium and magnesium, hydroponic setups usually require specific nutrient formulations. However, mixing it in small amounts following guidelines can support nutrient levels in mineral solutions for your plants, enhancing their growth and health. -
Question:
Is it safe for pets and children?
Answer: Roots Organics Elemental Supplement is formulated with organic materials, making it generally safer for the environment compared to synthetic fertilizers. However, as with any fertilizer, it’s best practice to keep it out of reach of pets and children. Advising caution during application will help ensure safety while benefiting your garden. Always adhere to the recommended usage instructions to minimize any risk. -

Hydrofarm Fertilizers & Plant Food ROEL9 Editorial Review
Roots Organics Elemental is an organic calcium magnesium supplement that comes in a 9 lb package. According to customer reviews, the product is easy to use and provides plants with the necessary Ca and Mg. However, some customers have reported that the product has a bad smell and doesn't dissolve well in water. Suggestions have been made to go for liquid supplements instead, even though they may be more expensive. One customer has also reported that the product is locally made. Therefore, unless you are sensitive to smells, the Roots Organics Elemental is a good organic supplement, but some customers may prefer a liquid supplement that dissolves better.
