Bells of Ireland Care
Bells of Ireland grow well in cooler climates, so if you live in a moderate and lesser humid region, it’s an ideal plant for your summer flower garden.
Light & Temperature
It prefers full sun if possible, but only if that means it’s not exposed to too much heat and humidity. If you’re growing this in a warmer climate, I recommend planting in in an area of your garden that gets some shade cover from the hottest parts of the day.
Water
Moluccella laevis enjoys a moderate amount of water, but be sure to avoid overwatering. During the growing season, give it around 1″ of water per week. If you’re not sure when to water, poke a finger into the soil and see if it’s dry to 1-2″ inches. If so, you’re clear to give it another drink.
To make your life easier, put it on automated drip irrigation so it’s evenly moist all of the time.
Soil
Choose a planting site with good drainage and at least average soil. It doesn’t need extremely rich soil to do well. If you’re planting into native soil, work compost into the first 6-8″ of soil to improve it a bit before planting in.
Fertilizer
You can always mix in some organic fertilizer into your planting site before transplanting, but if you want to fertilize your plants throughout their growth, make sure to give them a drench throughout the summer.
I recommend an organic liquid plant feed to support their growth during their most prolific blooming phase.
Propagation
Growing Bells of Ireland from seed is the easiest way to propagate this gorgeous flower. Here’s a simple process:
- Chill your seeds in the freezer before sowing to improve germination.
- Start seeds indoors 8-10 weeks before the last frost in your region.
- Transplant after your last frost when the ground is workable.
If you want a more hands-off approach, just let some of your flowers go to seed and they’ll naturally self-sow next season.
Pruning
There are no particular pruning needs for bells of Ireland plant as it is not an aggressive grower. However, if you don’t want the plant to exceed a certain height, or find the plant getting bushier than you like, you can always use gardening scissors to trim it down.
Harvesting
Once the green bells start showing up on the stems, you know it’s time to harvest for cut flowers. Remove all of the leaves from the lower part of the stem, as they’re older and likely to yellow quickly after harvesting. They’ll last up to two weeks in a vase in good conditions, so enjoy your bells!
Problems
Bells of Ireland plant is resistant to most diseases and pests. You may face some common problems that are discussed underneath.
Diseases and Growing Problems
If you see a yellowish halo appearing on the leaves, making them turn brown, it means your plant has developed leaf blight. The only way to get rid of this is to remove the affected part before the rest of the plant and garden gets infected.
Crown rot is when the plants wilt and die back at the soil line. Remove the affected plant and avoid growing it in the same place. Have the soil inspected before you start growing bells of Ireland in that area.
Pests
Aphids are most likely to start feeding on the undersides of the leaves. This makes them quite difficult to notice and you only locate them when they have damaged enough of your plant to hamper its growth. You need to remain vigilant, scanning the undersides every so often to keep a watchful eye.
If it is, wash the leaves by insecticidal soap or use a strong spray.
Little spider mites can suck your plant’s juices and replace chlorophyll with toxins. This will cause your plant to have a lacy, webbed appearance and yellow leaves. Use a hot pepper wax or high-quality insecticidal soap to deal with mites.
