Got irises? 8 fertilizing mistakes everyone makes in April that destroy summer flowers

6. Watering Incorrectly After Fertilizing in April

Proper watering is essential after applying fertilizer to ensure that nutrients are absorbed efficiently by the plants. However, over-watering can lead to nutrient runoff, while under-watering can prevent nutrients from reaching the roots.
Aim to water deeply but infrequently, allowing the soil to dry out slightly between waterings. This encourages deep root growth and ensures that the fertilizer is properly integrated into the soil without being washed away.
7. Ignoring Old Foliage and Weeds Before You Feed
Old foliage and weeds can compete with your irises for nutrients and space. Before fertilizing, it’s crucial to clean up the garden bed by removing any dead leaves, debris, and weeds.
This cleanup not only reduces competition but also helps prevent disease and pest issues, providing a healthier environment for your irises to grow. Once the area is clear, your fertilizer application will be more effective, reaching the intended plants without obstruction.
8. Fertilizing Stressed or Crowded Clumps Instead of Dividing
Irises that are crowded together may struggle to thrive, competing for nutrients and space. Fertilizing stressed or crowded clumps won’t solve the underlying problem and can even exacerbate stress by promoting excessive competition.
Instead, consider dividing your irises every three to five years. This process invigorates the plants, reduces competition, and provides more space for each plant to access nutrients. After dividing, a light application of a balanced fertilizer can help them establish strong roots and prepare for a robust blooming season.
