Your beds just spent a whole season feeding tomatoes, squash, and flowers. Whatever they pulled out is still gone. Here's how to find out exactly what's missing and put it back before the ground freezes.
Plants don't make nutrients. They mine them. A productive bed can strip a season's worth of nitrogen, potassium, and calcium out of the top few inches, and it does it quietly. The plants look fine right up until next year, when they don't.
The only way to know what's left is to measure it. The best time to measure is right now, while there's still time to fix it.
Right now
Late summer through fall is the low point. Everything your plants needed to fruit, flower, and grow came out of the ground, and the season is closing before it gets replaced.
Testing now shows you the true bottom, not a guess based on how things looked in July.
Soil Genie report
Organic amendments don't work overnight. Microbes need weeks to break them down, and winter moisture carries the nutrients into the root zone. Add them in fall and spring soil is ready. Add them in spring and you're feeding seedlings from a bag all summer.
Lab grade
A $34.99 test tells you what to buy. Without it you buy fertilizer, compost, lime, and amendments on instinct, and half of them fix problems you don't have. Over-fertilizing is real: it burns roots, locks up other nutrients, and runs off into places it shouldn't.
One test, and every dollar you spend on your beds afterward has a reason.
12 nutrients + pH
Hardware-store kits give you a pH color and a vague N-P-K range. Soil Genie sends your sample to a lab using the same standards farmers rely on, and comes back with a complete read on 12 vital nutrients and pH.
Results are typically back in 6–8 days, so you're still inside the fall window when they land.
Custom plan
Most soil tests hand you a page of numbers and wish you luck. Soil Genie interprets the lab results for you and turns them into a tailored protocol: what to add, how much, and when, based on your actual sample and not on regional averages.
You don't need to be a soil scientist. That part's done for you.
OMRI Listed
Post-harvest formula
Replenish_03 is a granular post-harvest soil food built for this moment: slow-release organic nutrients including calcium and potassium, humic acid, and beneficial microbes, all in one scatter-and-water application. It puts back what the season took out and rebuilds the biology over winter.
Formulated by a Cornell Ph.D. No synthetics. No plastic-coated pellets. Roughly 2 cups per 8'×4' raised bed; one 2 lb container covers up to 125 sq ft.
Postage prepaid
Scoop a few samples from your beds, mix, fill the bag, seal it, drop it in the mail. Everything is in the box, including the return postage. Your report lands in your inbox and your plan is ready before the first frost.
There's no version of this that's easier than doing it now, while your beds are still open and the ground is still soft.
Test first, replenish second. Or grab both and be done before the frost.
