Growing your own salad greens in urban planter boxes is both rewarding and practical. For two people to enjoy fresh salads regularly, you'll need approximately 2-3 medium-sized planter boxes. Each box should be at least 12 inches deep and 24 inches long to accommodate proper root growth.
The exact number depends on your salad consumption and growing methods. If you eat salads daily, aim for three boxes using succession planting - sowing new seeds every 2-3 weeks for continuous harvest. For occasional salads, two boxes may suffice.
Popular salad greens like lettuce, spinach, and arugula grow well in containers. Plant seeds about 4 inches apart, and you can expect to harvest outer leaves within 4-6 weeks. With proper care including regular watering and partial sunlight, your urban planter boxes can provide fresh greens throughout the growing season, reducing your grocery bills while ensuring pesticide-free, hyper-fresh salads right from your balcony or patio.
