When it comes to storing iris bulbs, proper care is essential to ensure their survival during the offseason and promote healthy growth when they are replanted. This comprehensive guide will walk you through the process of storing iris bulbs, ensuring your beautiful flowers return year after year.
1. Time it right
The first step in storing iris bulbs is determining the right time to remove them from the ground. This typically occurs after the plants have fully bloomed and their foliage starts to yellow, which usually happens in late summer or early fall.
2. Dig carefully
To avoid damaging the bulbs, carefully dig around the irises using a gardening fork or a small spade. Try to dig at least four inches away from the plant’s base to ensure you don’t accidentally cut any bulbs.
3. Clean and dry
Once you’ve removed the bulbs from the ground, gently brush off any loose soil and debris. Be cautious not to damage the roots or bulb itself during this process. Next, allow the bulbs to air-dry for about a week in a cool, dry place with good air circulation.
4. Inspect and divide
Before storage, you should inspect each bulb for signs of disease or damage such as rotting or mold. Discard any unhealthy bulbs to prevent potential problems from spreading during storage. Healthy iris bulbs can be divided at this point if necessary by gently separating them at their natural divide points.
5. Prepare for storage
Place each cleaned and dried bulb in a paper bag, mesh bag, or wrap them loosely in newspaper. Label each bag or bundle with the variety name or color so you’ll know which irises you’re working with come planting time.
6. Store properly
Proper storage conditions are crucial to keeping your iris bulbs healthy during their dormant period. Store them in a cool (approximately 40-50°F), dark, and well-ventilated area. A basement, garage, or even a cool closet can work well for this purpose.
7. Check on them periodically
It’s important to check your stored iris bulbs periodically throughout the offseason to ensure they remain healthy. Look for signs of mold or rot and remove any affected bulbs immediately to prevent the spread of disease.
8. Replanting
When spring arrives and the ground has thawed, it’s time to replant your iris bulbs. Choose a well-draining garden bed with plenty of sunlight, and plant the bulbs approximately three inches deep and spaced about 12-18 inches apart.
By following these simple steps for storing iris bulbs, you can look forward to beautiful blooms gracing your garden each year. With proper care and attention, your irises will continue to thrive and brighten up your outdoor space season after season.
