  • Description
  • Other Details
  • This bottle of fertilizer is stinky, but that's what makes it the best choice for your plants. Processed in the Pacific Northwest, it is derived from acidulated fish solubles stabilized with phosphoric acid and contains a variety of species of fish for greater mineralization. The organic matter of the decomposed fish feeds mycorrhizae, building healthy bacteria throughout the soil to promote robust plant with no phytotoxic effects or root burn. This enables the plant to readily receive key nutrients. To use as a soil application, mix 4 oz. of fertilizer per gallon of water to create solution. One gallon of solution is enough for 2-3 roses.

    Large sizes ship free. *Product packaging may vary.

Which Soil Looks Most Like Yours?

Sandy soil causes rapid drying and nutrient loss. Our recommendation to amend soil is Heirloom Roses Mint Compost, which holds moisture and nourishes microbes for healthier growth.

Loamy soil can lose fertility and structure over time. Our recommendation to amend soil is Heirloom Roses Living Soil, which restores balance, retains moisture, and sustains long-term fertility.

Clay soil drains poorly and compacts easily, suffocating roots. Our recommendation to amend soil is Heirloom Roses Aged Cow Manure, which improves structure, boosts nutrients, and supports healthier root growth.

Why Enhancing Your Soil Matters

1

Drainage

Healthy soil lets roots breathe. Amending clay loosens compaction, preventing waterlogging and disease — giving plants a stronger start and longer life.

Retention

Amendments enrich sandy soil to hold both moisture and nutrients, reducing stress and fertilizer loss so your plants thrive between waterings.

Nutrition

Loamy soil starts ideal but breaks down without care. Light, regular amendments keep its structure intact, feeding plants and sustaining blooms year after year.

Protection

Silty soils crust, compact, and erode easily. Organic matter and cover reduce runoff, protect topsoil, and anchor nutrients where roots need them.

Absolutely Amazing….

I purchased this along with a couple of new roses and applied it to every rose I have. This magic liquid completely shocked me with the results! I have many old roses that have just limped along and now they are completely stunning with new growth and so many roses. This stuff is magic! And of course… My new roses are growing awesome.

Founders Fsh Oil

I've used Founders Fish oil twice on all my roses since receiving it on May 23rd if this year and it seems to be improving the growth and development of my rose plants. It's probably too early to tell, but Founder's fish oil certainly isn't hurting them. The blight problem I had with my plants seems to have been eradicated. Although not connected either way with Founders Fish Oil, it's important for me to note that there was mention in the news of an "agroterrorist mold" that seems to have originated in Michigan and we should all be aware of it. I don't know if the mold (blight) problem I had was that mold, but it certainly was virulent enough to be. I have been watering my plants with a mixture of water and baking soda as recommended by Heirloom Roses and it seems to have solved the mold problem.

Roses are thriving

My roses absolutely love this fertilizer. I’ve repurchased it a couple times and finally just bought the largest size when it went on sale. Totally worth the investment! A little goes a long way and my roses just keep blooming.
