10 minute job. Just take it out and go to your nearest sprinkler supply house. They will give you the exact replacement and the correct nozzle. Probably even adjust it for you. Might cost 5 dollars more than HOMERDEPOT, but well worth the difference in expertise. The highschool kids that work in the big boxes won't know a thing.

I agree with others here who have suggested mosquito dunks. There are also smaller pellets that you can sprinkle in the water called mosquito bits that contain the same active ingredient, Bacillus thuringiensis israelensis (Bti) bacteria. This bacteria is lethal to mosquito larvae, but is harmless to humans and animals. If you use mosquito bits, simply sprinkle some on the surface of the water until the surface is covered. Getting a water pump for your bird bath is another way to discourage mosquitoes from breeding in the water. The added bonus with that solution is that you'll attract even more birds, because birds love the sight and sound of moving water. Best of luck!

Can't say enough about the benefits of predatory "bugs", our true bugs. Nothing makes me happier than to see a cog wheel bug or an assassain bug perched quietly among my plants, waiting patiently for an unsuspecting catepillar to come strolling past. And the next time you start to swat a fly, you might want to see what kind it is...some of our most common flies also parasitise caterpillars. We are so caught up in our need for immediate gratification...we really want to see results NOW. It is tough to reassuringly tell yourself about balance and long-term fluctuations when you can see the damage being done to a prized planting on a daily basis. And there isn't always a handbook to tell you what the threshold is-the point at which you either take evasive action or suffer a complete loss. I am reminded of the cicada hatching we had here several years back. All you could do was clap your hands over your ears when you went out and stare in disbelief at the branches completely covered with those shiny black insects. How could the trees possibly survive that sucking screaming carpet? But then things quiet down eventually and the scavengers clean up the last of the carcasses and you see that aside from a few dead branches and weakened individual trees, they came out of it ok. Unless the invader is a foreign one and the ecosystem has no defenses for the newcomer, there is always a check and balance.

I'm growing multiple types of viburnums, but the V. trilobum bushes are the largest and oldest. Supposedly humans can eat them, prepared like cranberries. I guess it is just a disappointment when nothing seems to want to eat them "as advertised". I guess the one good thing is that they can be enjoyed as decoration for the entire time since the berries hang on until they fall off in spring. Flocks of robins came in early January, but did not return again in numbers to our area in PA, while they came back several times by the hundreds to our suburban lot in Maryland (on a hill). Why do I never see any cedar waxwings in N. Central MD? My inlaws said they had them in Alexandria, VA (at least once on their holly)
