### Clue: Plant a piece of land (4,6)
### Answer: HERB GARDEN 
 ### Explanation: Definition: a piece of land
 I'm not sure about this clue. If the definition is as underlined, HERB(a plant) + GARDEN(to plant), requires "plant" to be implicitly used twice. Alternatively, it is HERB(a plant) + GARDEN(a piece of land), with a missing definition.
