Small leafy greens need a draining container and regular moisture checks. Use identified seed and plan the pot around how the crop will be harvested.
Name the crop before sowing
Small leafy greens include crops with different seasons and mature sizes. Choose labeled seed suited to the balcony's light and expected temperatures. An enclosed balcony may become much hotter than the outdoor forecast suggests.
Prepare a container for roots and drainage
Use a clean suitable pot and growing medium, leaving room for watering without washing seed out. Follow the packet for sowing depth and spacing. Thin young plants when needed instead of letting a crowded seedling mat compete indefinitely.
Keep moisture steady during growth
Check shallow containers frequently, especially in wind. Water the root zone when needed and let surplus escape. Persistent wetness, poor air movement and crowding can damage seedlings; repeatedly adding fertilizer will not correct those conditions.
Harvest at an appropriate stage
Some greens suit repeated outer-leaf harvests, while others are cut whole. Use the method for that crop and leave enough growth where regrowth is expected. Sow small successive batches if a continuing supply is wanted rather than one oversized sowing.
