Dracaena Marginata Tricolor pests — FAQ
What is eating my dracaena marginata tricolor?
Dracaena Marginata Tricolor is moderately susceptible to indoor pests. Scale insects and mealybugs are the most common problems, colonising the cane stems and leaf bases. Spider mites thrive in the dry air of heated rooms. Thrips can damage the striped foliage. Healthy plants in bright indirect light resist pests far better than stressed ones.
