For the life of me I can not grow my favorite herb. What’s the secret?
I struggle to grow it too, so no real help there - it's hit or miss for me. This rainy extra cool summer yielded very little so maybe it does need more sun for me.
If you get it to grow and it 'bolts', know that the green seeds are amazing! As Samin Nosrat taught me:
Here's a small excerpt (article is probably behind a paywall)
Green coriander seed — the fresh seed of the cilantro plant — is the most special thing I grow and something many others view as a mistake. “Cilantro can be hard to grow,” says Leslie Wiser, founder of Radical Family Farms in Sebastopol, Calif., “because it bolts easily.” When a plant bolts, or prematurely goes to seed, its flavor changes. Gardeners dread bolting, but when it comes to cilantro, I actively pray for it, because nothing is as welcome in my kitchen as the intensely aromatic, slightly citrusy, mildly cilantro-ish flavor of the plant’s fresh green seeds.
