Seasonal Considerations

🌸 Spring Care for Japanese Iris

Spring is the perfect time to rejuvenate your Japanese Iris. Start by fertilizing with a balanced NPK fertilizer to boost growth and vitality.

If your clumps are overcrowded, consider dividing them. This not only promotes healthier plants but also enhances blooming potential.
