Microgreens Fertilizer

It depends on the crop and the medium. A short crop like radish, cut at a week, can grow on the reserves in the seed alone. Anything grown past seven to ten days has used those reserves up, and a tray on a soilless mat has nothing else to draw from, so growth pales and slows. Microgreens Fertilizer is a liquid feed for exactly that point: added to the water, it gives sunflower, pea and broccoli shoots the nutrients to green up and bulk up before harvest.

With every watering. Microgreens Fertilizer is made to go into the water rather than be applied as a separate dose, so mix it at the recommended dilution each time you water the tray, from germination until a day before you cut. That steady, light supply suits a crop that grows for only a couple of weeks: there’s no time for a slow-release product to break down, and a liquid is available to the roots immediately. Water with plain water on the final day before harvest.

Yes. Microgreens Fertilizer supplies mineral nutrients that the shoots take up through their roots, the same way any plant does, so the fertilizer isn’t sitting on the part you eat. Feed at the recommended dilution with each watering, switch to plain water for the last day before harvest, and rinse the cut greens as you normally would. Grown that way, a fed tray is handled exactly like an unfed one once it reaches the kitchen counter.

Any tray. Microgreens Fertilizer is formulated for microgreens and shoots as a group, and sunflower shoots, pea shoots, radish, broccoli, arugula, kale and mustard microgreens, and wheatgrass all need the same thing at that stage: an immediately available feed to carry them past what the seed provides. Whether you grow on soil or on a soilless mat, the mix and the every-watering routine are the same, which makes it simple to run several varieties side by side on one schedule.

Quickly, because microgreens grow quickly. Shoots fed with Microgreens Fertilizer typically come in greener and taller within two to three days of the first feeding, since a liquid in the water is available to the roots immediately and nitrogen drives leaf growth on a crop this young. The clearer measure is at harvest: a tray fed with every watering carries noticeably more weight than one grown on the seed’s reserves alone, especially for longer crops and anything grown on a mat.
