Is Something in My Garden Soil Killing My Tulip Bulbs?
I planted about 100 bulbs 6 years ago in my front garden. They had been coming up strongly for 4 years. Last year there were a number of empty spots where there should have been bulbs. I planted some more there. But this year, only about 5% of the bulbs came up. Other things in garden did fine: azalea bushes, primrose, petunias and vinca. The last three are located right around or over the bulbs. I am thinking of planting some more tulip bulbs there, but I am concerned there is some disease or chemical problem in the soil that may kill off the new bulbs. Any thoughts? Thanks
Since other plants are growing well in the area, it's unlikely that there is a chemical problem.
We had record-breaking rains over the past two years and many plant drown. It the soil in that area tends to be soggy for a long time after rains, they may have rotted.
A more likely culprit is voles. These rodents love to eat bulbs (Moles, on the contrary, do not eat bulbs.) Here is info about voles: https://extension.umd.edu/hgic/topics/voles Dig in the area where you planted the bulbs and, if you find no bulbs, that points to voles.
