🧠 Container Gardening Tips for Maximum Success

• Use high-quality potting mix, not garden soil (too dense).
• Add drainage holes to any container you use.
• Water consistently—containers dry out faster than ground soil.
• Rotate crops between seasons to avoid pests and soil fatigue.
• Feed plants with organic fertilizer every 2–4 weeks.
