Could you let me know names of early flowering shrubs that attract bees?
This article lists some early flowering shrubs:
I have found when I have purple flowers lots of bees are around, like mexican heather.
My husband says plant pollen that bees collect is red, blue, or yellow. I say it is all yellow, and it is the flower color that varies not the pollen color. Can you help us out?
Pollen color can vary and occasionally (rarely and only in a handful of plants) it can be red or blue. Normally, however, it does not stray from the yellow/brown/green spectrum.
I was wondering if you use the solution suggested on your site to treat aphids, can you also add ladybirds to the plant or does the solution (oil, water, detergent) damage or interfere with the ladybirds as well?
I would do one or the other. Doing both can hurt the ladybirds if they are on the plant.
I have an infestation of bagworms (about 3/4 inches long now) throughout my shrubs. I also have a huge hatching of praying mantis in the same shrubs. How can I kill off the worms without harming the mantis?

Will dusting for bugs on flowering vegetables keep bees from pollinating them?
Yes, it will. We have found neem to be a good insecticide. It will kill the bad bugs but is not harmful to bees, people or animals. Here is more information:
Can the oil/water/soap solution (recommended in your page on aphid control) be used concurrently with ladybugs (i. e. is the solution toxic to ladybugs)?
You have to spray the soap solution directly on the aphids to eliminate them and be sure to check the underside of leaves too. Using soap-like solutions on aphids allows predator insects (such as ladybugs, which have harder bodies) to survive and naturally control aphids. In other words, the ladybugs should be just fine.
I was told that praying mantis bugs are good for the garden because they eat all the bad insects. Is this true, and can you explain what they do and are they good in a vegetable garden?
Yes, the praying mantis is a popular garden friend. This insect will feed on virtually any type of bug including crickets, beetles, caterpillars, aphids, and leafhoppers. It's a great asset in the garden, both flower and veggie gardens.
