If you love outdoor topiaries, did you know that it is actually easy to grow certain topiaries indoors. The key is plenty of light and the right variety of plant to tolerate the dry conditions inside. Most of us are familiar with the English Ivy topiary. Lush and green English ivy will grow successfully indoors with a least 4 hours of very bright light. But the real problem is usually insects, especially spider mites. Spider mites will kill ivy in a matter of just a few weeks. What to do? Spray your topiary every 4 weeks with a insecticide and miticide. I use a great product called Triple Action Plus by Fertiliome. You can find this spray at my shop, Botanica Gardens in Little Rock, or other garden centers.
Other varieties of topiaries include rosemary and the olive tree. Both should be cared for just like you would the English ivy. Keep moist and do preventive maintenance. Rosemary will require about 6 hours or more of bright light.
