Rhubarb Seed Starter Grow Kit

Rhubarb is the tart 'pie plant,' a hardy perennial whose ruby stalks shine in pies, jams, and crumbles. How to grow Rhubarb from seed Sow your seeds at the depth listed on the included instruction card and cover lightly. Then set the clear humidity lid on top to hold warmth and moisture. Keep the planter warm and in bright light, and mist the surface whenever it begins to dry. When your Rhubarb sprouts appear, remove the lid and move it to your brightest window or under a grow light.
