Sustane 3-5-3 Compost Tea Bag | 12ct - 21gm Packs - OMRI Listed - (Case of 10)

Steep-and-Apply Organic Compost Tea in Biodegradable Bags, 12ct

Brewing compost tea from loose compost usually means straining solids out of a bucket before it can go through a watering can or sprayer, which discourages a lot of growers from trying it. Sustane's 3-5-3 Compost Tea Bags package an organic slow-release fertilizer inside a biodegradable paper filter pack, so the straining step is already built in.

Steep one pack per gallon of water in a watering can for one to two days, then apply the resulting liquid to soil as a drench, with 12 packs per box sold in a case of 10 boxes.

Frequently Asked Questions

How do I brew and apply the compost tea?

Steep one bag per gallon of water in a watering can for one to two days, then apply the liquid directly to soil as a drench around the root zone. No straining is needed since the paper pack contains the solids.

What does the 3-5-3 ratio mean for this product?

3-5-3 refers to the guaranteed nitrogen, phosphorus, and potassium percentages in the fertilizer inside each bag. That's a lighter overall concentration suited to a liquid drench, compared with the heavier granular ratios in Sustane's bagged fertilizers.

Can I reuse a bag for a second batch of tea?

The bag is formulated for a single one-to-two-day steep, so a second steep would deliver meaningfully weaker tea. Using a fresh bag for each batch keeps nutrient delivery consistent.

Is this product OMRI Listed?

Yes, Sustane's 3-5-3 Compost Tea Bags are OMRI Listed, certified for use in organic production. The certification applies to the full case as well as individual boxes.
