Good to know

Fertilizer finder questions.

How does the fertilizer finder pick a match?
It scores every Old Cobblers Farm fertilizer against your answers — what you’re growing, your nutrient goal, organic preference, and soil notes — using the real N-P-K and best-for data behind each product. The closest fits rise to the top, and each card explains why it matched.
What’s the difference between Wicked Growth and Wicked Organics?
Wicked Growth is our conventional line — concentrated, fast-acting blends. Wicked Organics is OMRI-minded, slow-release, and soil-building. The finder lets you filter to either, or see both if you have no preference.
How much fertilizer do I actually need?
On your results, enter your area in the coverage calculator and we’ll estimate how many 5 lb bags your top match needs, based on its real application rate. Always confirm exact rates on the product page before applying.
When should I fertilize in New Hampshire?
Timing depends on the crop — lawns green up best with spring and fall feedings, gardens at planting and mid-season, fruit trees before bud break. Each product’s guide page has NH-specific seasonal notes.
I’m still not sure — can someone help?
Absolutely. Email info@theoldcobblersfarm.com with what you’re growing and we’ll point you to the right feed.
