Nasturtium microgreens seeds should be soaked for a few hours before planting. It helps water penetrate the large, hard seed husk.
You can grow these with the weighted and buried blackout method. We prefer the buried method as it keeps the larger seeds moist and is less prone to disease.
Nasturtium microgreen seeds germinate slowly but grow quite quickly after they germinate.
The stems of Empress of India Nasturtiums are a rosy pink and very attractive.
Nasturtium microgreens are ready to harvest in 10 to 14 days. You want two sets of leaves to form before harvest.
The flavor is unique as it changes from a sweet, salty, fruity flavor finishing with a very sharp bite. It surprised me the first time I ate nasturtium microgreens.
Although I call these nasturtium microgreens, they grow to what I like to call baby leaf size before harvest.
