Two light bulbs need replacing on the same day, and we say it's just a 'coincidence'.
The soil may be too wet; most bulbs need good drainage.
The bulbs are still alive and need to be kept strong.
But many gardeners forget that the bulbs need some light to form flowers for the following year.
Most bulbs need a place between full sun and part shade.
To turn into beautiful flowers, bulbs need some love, too.
That reminds me, the light bulb in the bedroom needs to be changed.
Is there a simple way to determine which bulb needs to be replaced?
And the bulbs almost never need changing - one thing less for this couple to have to think about.
Then in the summer, the covers provide dry, warm conditions which many such bulbs need.
