Giroud Treats Destructive Pests With Horticultural Oil

Scale, Mites and Adelgid damage trees and shrubs. Horticultural oils are a Green approach to treating these destructive pests. Drew Slousky, ISA Certified Arborist, and Ken Watson, PA Certified Applicator, explain how Giroud uses Horticultural Oils and show treatment being applied on Pines, Azaleas and Arborvitaes.

Check your trees for the following warning signs: white cottony spots, rust colored needles, major needle loss or excessive thinning. Ask your Giroud Arborist to inspect your trees to determine if treatment is needed.

Tree Spotlight: Syringa Reticula

With a profusion of perfect, creamy, fragrant flowers and cherry-brown bark, the Syringa Reticula (aka Japanese Tree Lilac) is possibly the most trouble-free lilac you can grow. Hardy and tough, the Tree Lilac is resistant to mildew, borers and scale. It grows 20-30 feet tall and blooms in early to mid-June.

Follow these steps to maintain a healthy and beautiful plant:

• Provide water during bloom and heavy growth periods.
• Prune to ensure good air circulation and to maintain shape.
• Prune immediately after flowering to avoid removing flower buds.
