Gladiola Secrets You Never Knew Could Change Your Garden Forever Gladiolas—those bold, architectural blooms with dramatic spikes of color—have long been the star of bouquets and formal gardens. But beyond their striking visual appeal, these perennial corms hold hidden secrets that can transform your garden into a thriving oasis with minimal effort. If you’re ready to unlock the full potential of gladiolas and elevate your green space, here are the surprising truths every gardener should know. ### 1. Gladiolas Are Disease-Resistant Powerhouses
Unlike many flowering bulbs, gladiolas naturally resist common fungal and bacterial diseases, especially in well-drained soil. This natural resilience means fewer chemical treatments and healthier plants. However, to maintain this advantage, always plant corms in fresh, well-aerated soil and avoid overcrowding. Rotate your planting site every 2–3 years to prevent soil-borne pathogens from establishing. ### 2. Strategic Planting = Year-Round Blooms
Most gardeners plant gladiolas in spring, but did you know they’re heat-tolerant when planted at the right time? For spring flowers, plant corms 6–8 weeks before last frost. For summer-flourishing displays, start them indoors 6–8 weeks earlier and transplant after the threat of frost. By staggering planting times, you can enjoy gladiolas blooming from late spring through fall—transforming your garden into a pulsing canvas of color.
