Buying Guide: Red Flowering Summer Bulbs
What should I consider before buying?
- Sun exposure: Most red bulbs perform best in full sun to partial shade. Match a bulb’s tolerance to your garden’s light profile.
- Soil drainage: Proper drainage prevents rot. Amend heavy soils or choose bulbs known to tolerate moisture if your bed stays damp.
- Bloom window coordination: Stagger planting times to extend the color season. Combine spring-blooming with summer-blooming varieties for continuous color.
- Planting depth and spacing: Follow seed or bulb packaging guidance. Correct depth supports bulb development and root growth.
- Container considerations: When planting in pots, use well-draining potting mix and ensure adequate space for growth and airflow.
How to plant red flowering bulbs for best results?
- Prepare beds by loosening soil to encourage root formation and mix in compost for nutrients.
- Plant bulbs pointy end up, at the depth recommended on the product label, and space according to mature size.
- Water thoroughly after planting and maintain consistent moisture until shoots appear.
- Mulch to conserve moisture and suppress weeds, but ensure mulch does not cover the bulb’s growing point.
Watering, feeding, and care tips
- Water deeply rather than frequently to encourage deep root systems; reduce watering after blooms fade.
- Feed with a balanced, slow-release fertilizer in early spring or per label directions for best growth.
- Deadhead spent blooms where possible to encourage flowering and maintain garden aesthetics.
Selecting the right mix for your space
- Bed or border: Choose tall varieties like gladiolus or crocosmia for backdrops and color contrast.
- Containers: Pick compact or medium-height varieties such as ranunculus or tulips for dramatic color in pots.
- Pollinator-friendly choices: Gladiolus and crocosmia attract butterflies and hummingbirds, boosting garden biodiversity.
