How long after first planting can you harvest?

Please provide me with more information about what you are planting! I need to know the type of plant or crop before I can tell you how long it takes to harvest.

For example, you could tell me:

* The specific plant name: "How long after planting can I harvest tomatoes?"

* The plant type: "How long after planting can I harvest a leafy green?"

* The crop category: "How long after planting can I harvest a root vegetable?"

Once you give me more context, I can provide you with an accurate answer.
