Islamic Interpretation of Dreams (Ibn-i Sirin):

(Greenhouse; Hotbed) In a dream, a nursery represents profits, annual return or a fertile woman. Owning or attending a nursery in a dream means victory, prosperity, marriage, acquiring knowledge, training in arts, or repenting from sin and harvesting the fruits of one’s repentance.

If the fruits of one’s plants turn into gold or silver in one’s dream, it means either benefits, profits, or that a disease will impair the growth of one’s plants, or it could mean unsalability of one’s crop.
