We have had a cool wet spring punctuated by 85-degree (F.) days here and there. This is the perfect opportunity for development of cedar apple rust – which looks like an alien from "The Invasion of the Body Snatchers."
The native Eastern red cedar – actually a juniper (Juniperus virginiana) – is particularly susceptible to rust, and these gelatinous galls form, swell, and release spores that affect apples and crab apples in my yard.
Pondering the choices
I could cut the cedar tree down. That’s what happened in the history of Winchester, an apple-growing town in Virginia. At a time when acres and acres of apples were grown commerically in the area, residents of the town culled all the Eastern red cedars to protect the apples. The soils in the area were shallow and not suited for other agricultural pursuits before the development of the chemical-supported agriculture we have today. Now they spray the few orchards left, and junipers can grow again.
I could cut down the apple tree. After all, it is near the Eastern red cedar and always gets a bad case of cedar apple rust and therefore no apples worth anything are harvested. And then I could plant the heirloom ‘Arkansas Black,’ a wonderful cedar apple rust-resistant variety with delicious apples that store well.
Or I could finish pruning the roses and grapes, which is what usually resolves this mental dilemma and takes my mind off the problem until next spring when the galls will reappear and I will ponder again. Ah, spring.
If you also have cedar apple rust, here are some good sources of infomration:
