I grew up in that time when you kept the cemetery plot clean, checked on the plantings in August, and planted fresh plants on November 1.
I was able to learn which plants could survive a summer drought – and in doing so transferred some of that knowledge to gardening.
Here are some cemetery planting ideas though this cemetery has watering devices. Most woody shrubs will survive at a two to three year establishment period as will crape myrtles. Cedar Elms are the most hardy of the cemetery plants in Texas.
