Frequently Asked Questions
How is Bloomin' Soil different from Ancient Soil?
While both products contain beneficial ingredients for plant health, they serve different purposes. Ancient Soil is our all-purpose soil amendment for general plant health and growth. Bloomin' Soil is specifically formulated with ingredients that target the flowering and fruiting phases of plants, with higher levels of phosphorus, calcium, and other nutrients that promote blooming.
Can I use Bloomin' Soil on non-flowering plants?
Bloomin' Soil is specially formulated for flowering and fruiting plants, so while it won't harm non-flowering plants, it's not the most efficient use of the product. For foliage plants, herbs, or other non-flowering plants, we recommend using Ancient Soil instead, which is formulated to support overall plant health and growth.
How often should I apply Bloomin' Soil?
For most flowering plants, apply Bloomin' Soil every 4-6 weeks during the active blooming season. For perennials, apply at the beginning of the growing season just before bud formation, and reapply mid-season if the blooming period is extended. Always apply a fresh layer when repotting or planting new flowering plants.
Can I use Bloomin' Soil in combination with other fertilizers?
Yes! Bloomin' Soil works well with other organic fertilizers, especially our Bloom Juice. The combination of slow-release nutrients from Bloomin' Soil and the immediately available nutrients in Bloom Juice creates an ideal feeding system for flowering plants. However, avoid using with fungicides, as they may disrupt the beneficial microbes in Bloomin' Soil.
Is Bloomin' Soil safe for edible plants?
Absolutely! Bloomin' Soil contains only natural, organic ingredients with no synthetic chemicals or additives or peat. It's perfect for edible flowering plants like tomatoes, strawberries, and other fruiting vegetables. It's completely safe for use around children, pets, and wildlife.
What's the difference between using Bloomin' Soil and just using a phosphorus fertilizer?
While phosphorus is important for flowering, Bloomin' Soil provides a complete, balanced approach. It contains not just phosphorus but also calcium, beneficial microbes, and a range of micronutrients that work synergistically to support all aspects of the flowering process. The organic, slow-release nature of Bloomin' Soil also prevents nutrient runoff and provides sustained nutrition throughout the blooming period.
