SPOKANE, Wash. (AP) — It may be called weed, but marijuana is legendarily hard to grow.

Now that the drug has been made legal in Washington and Colorado, growers face a dilemma. State-sanctioned gardening coaches can help folks cultivate tomatoes or zucchini, but both states have instructed them not to show people the best way to grow marijuana. The situation is similar in more than a dozen additional states that allow people to grow the drug with medical permission.

That's leaving some would-be marijuana gardeners looking to the private sector for help raising the temperamental plant.
