Kohlrabi germinates in three to five days even in a cool room, tastes mildly sweet, and has more crunch than most brassicas. There is one deadline you should not miss.

Bronze fennel is slow — around three weeks — and it is the only microgreen that tastes of anise. It is also the prettiest thing you can put on a plate of fish.

Rainbow chard gives you red, yellow, orange, pink and white stems under dark green leaves, with a sweet beet-and-spinach flavour. Ready in about 12 days — and the seed has one requirement you cannot skip.

Cutting celery takes about four weeks — four times longer than radish. It is the only microgreen that tastes like celery, and for anyone who cooks soup that turns out to be worth the wait.

Amaranth, sorrel, basil and watercress seed is close to dust. Scattering it by hand gives you clumps and bald patches. Four techniques that fix it, none of which need equipment.

Sorrel is the only common microgreen that is genuinely sour. It is slow, the seed is expensive, and a small amount of it will do more for a dish than a whole tray of something else.

Most microgreen mixes taste like a vague green blur. A blend that actually works has three jobs in it — a base, an accent and an edge — and knowing which crop does which is the whole trick.

Bacteria get inside the plant during germination, where rinsing cannot reach them. That single fact rearranges every piece of microgreen safety advice you have read.

Microgreens have been recalled for Salmonella — most often broccoli microgreens. Here is the contamination record, why it happens, and what genuinely changes the risk.

Researchers digested Brassica microgreens in a lab and fed them to human gut bacteria. Different crops fed different microbes — and produced different short-chain fatty acids. Here is what that does and does not tell us.

A 2026 study found sunflower microgreen extracts inhibit alpha-amylase — the enzyme that turns starch into sugar. Here is what that result means, and the four steps between it and your dinner.

Broccoli, radish, sunflower or pea — which microgreens actually have evidence behind them for blood sugar? A crop-by-crop look at what has been measured, and what has not.

Freeze-drying preserved the most pigment and phenolics. Microwave and air-fryer drying changed which compounds survived rather than how many. Across both studies, fresh scored highest on activity.

Pathogens introduced through irrigation water did not just reach the plants — they persisted on them and in the growing medium. Water is not the neutral thing that carries everything else.

Contaminated seed is a primary route by which pathogens enter microgreens — and seed is the single ingredient a home grower inherits from the supply chain. Here is what has been tested, and why we are not publishing a recipe.

Microgreens grow in warmth and humidity — conditions that suit bacteria as much as plants. One study found that how much contamination got in barely mattered. That result is worth understanding before you decide how to grow.

Zinc enrichment raised bioaccessible zinc seventeen-fold in radish. It also lowered iron. The antagonism between these two minerals — and the discovery that light is a separate lever entirely — is what makes this worth understanding.

Four species grown with iodine in the water raised tissue iodine by an average 227%. The more valuable result is what stayed the same — dry matter, colour, and critically, nitrate.

Kale microgreens grown with selenate in the nutrient solution accumulated 893 µg/kg. Sprayed on the leaves, the same element reached 24. The gap is the most useful thing in the study.

Put a mineral in the water and the plant takes it up. That is a real, measured technique with published numbers behind it — and three trade-offs that rarely get mentioned alongside them.
