Description: Organic seeds for growing baby greens indoors through winter. These organic nasturtiums are compact and particularly well suited for indoor growing. They flower in red yellow and orange - and all parts are edible including the pepper leaves and lovely blooms!  Nasturtiums are spicy and light-up winter salads with bold flavour and dazzle as a garnish on winter soups. 

Easy steps for growing nasturtium as baby greens indoors through winter:

  • Nasturtiums grows most productively under full spectrum (6400K) grow lights. We recommend Sunblaster T5 lighting. Grow lights should be maintained 6 - 12” above plant tops and should be on 16 - 18 hours per day.
  • During the months where daylight-hours are low, nasturtiums are not able to grow productively without support from full spectrum grow lights (even on the sunniest windowsill or greenhouse). 
  • Nasturtiums grow very well in 5" tall x 6" wide pots with drainage. Compared to other indoor greens nasturtiums benefit from a deeper pot and some space to spill out of their pots.
  • For completely easy baby greens use a composty soil. We use an organic potting mix  blended with Sea Soil compost at a 60 / 40 ratio. By building in high quality compost you can avoid any need for additional fertilizing.
  • Nasturtiums take 10 - 14 days to germinate but come up faster if seed is pre-soaked for 12 - 24 hours (but not longer). The ideal temperature for germination is 18 - 21º C; bottom heat will speed up germination and encourage faster seedling development.
  • Wet your soil medium before sowing then press seeds into soil surface at approximately 15 - 18 seeds per 6” pot. Press seeds into soil to a depth of 1/4" and spritz (or carefully water) to fully moisten. Nasturtiums require darkness to germinate; keep them away from the grow lights until seeds start to emerge. 
  • Check on seeds every few days to notice when they are starting to germinate. Maintain soil moisture without allowing the mix to be soggy.
  • Nasturtiums will grow as a baby green for approximately ten to twelve weeks before a new crop needs to take over. Sow new trays every month to keep a constant supply.

    Additional Tips:

    • Great air circulation around your indoor garden makes everything better! If you are growing lots of plants indoors consider adding a small fan to your set-up.
    • If using humidity domes over your trays: be sure to leave these off for at least one hour per day to allow for air circulation.
    • Pests rarely occur on baby greens but it is a good idea to clean pots/trays with warm soapy water (or 10% bleach solution) between crops and generally keep your growing area tidy.
    • Crops that are grown to larger than baby green size will likely require fertilizing for best productivity; we recommend Evolve Organic All Purpose Fertilizer for our indoor gardens.

    Harvesting Tips:

    • Harvest leafy greens by up to 50% with each cut.
    • Remove flowers (and eat them!) regularly to encourage more blooms.
    • Use sharp scissors to cut your greens - this helps plants regrow more quickly after harvest.
    • The beauty of growing your own baby greens is that you can harvest just what you need when you need it!
