Notes: It is difficult to grow cilantro profitably in a greenhouse as it is relatively low priced and plentiful in the markets year round. Cilantro requires cool temperatures or it will bolt. Cilantro grows best in full sun. Only the immature leaves are sold. (The mature ‘feathery” leaves that precedes bolting are not desirable.) To grow in slab: upon final harvest, pull out plants by the roots and re-seed directly into slab or transplant. Harvest by cutting tops to crown and allowing to re-grow – or pull up by the roots and bunch. Consider selling bunches with stone wool left on.
