Hardest Herbs to Grow Indoors
Basil: It’s a favorite to cook with, but it’s a tough one to grow. Your best shot is to grow it during the warm, bright summer months. Connie Campbell suggests the Spicy Globe or African Blue variety, the latter of which is more like Thai basil and does well indoors.
Cilantro: Cilantro is the name for the stems and leaves of the coriander plant. It often bolts, meaning it starts growing flowers and seeds instead of leaves. Leslie Land, gardening columnist and blogger, sows coriander seeds in a shallow flat (a plastic tray), then eats them as sprouts, root and all. “Sow the coriander seeds quite thickly, like almost paving but not quite. Only let seedlings get about four to five inches tall, then pull them up, roots and all, and wash them.” To make this economical, she says, just pick up coriander seeds in bulk at a health food store.
Sage: Rose Marie Nichols McGee says that sage is more susceptible to mildew and is very sensitive to overwatering. If you want to try it, though, Connie Campbell says to go for the dwarf sage, which is more compact than regular sage.
