Bluebell flowers tolerate moderate to dry soil. Water the bluebells after planting and every couple of days the first month to stimulate the roots to take hold. Maintaining the bluebells after that involves making sure the plants get around 1 inch of water a week. This can be rain water or water from your garden hose.
Beside above, do Blue Bells spread?
Bluebells can spread rapidly. They seed freely and often hybridize when grown together. The bulbs can also persist in garden compost heaps.
Subsequently, how big do Blue Bells get?
Do bluebells come back every year?
Do bluebells come back every year? As a perennial plant, bluebells flower every year. Bluebell colonies take between 5-7 years so develop and can take some time to recover if damaged.
Bluebells flower for about two months.
The perfect time to plant bluebell bulbs is in the early autumn (September/October time). Plant bulbs at least 10cm deep and 10cm apart, and make sure that the pointed end is facing upwards.
English and Spanish bluebells (and presumably the hybrids) are poisonous. They contain chemicals called glycosides, which are toxic for humans, dogs, horses, and cows. All parts of the plant are toxic. Eating any part of the plant can trigger nausea, vomiting, diarrhea, and a decrease in the heart rate.
Allow the foliage to die down naturally after flowering. It is a good idea to remove the faded flower spikes before they set seed to prevent the plants self-seeding and spreading where they aren’t wanted. Bluebells are rarely troubled by any pests or diseases.
