Regan's Nursery in Fremont California is an amazing resource for the home gardener. Besides having a vast array of plants, they also offer garden decor, furniture, and landscaping advice. But best of all, when you walk in with your pest infested plant, they are more than happy to take the time to evaluate the sad item and give advice as to what would be best for treating the problem. They offer many options for planting your garden also. Everything from seeds to 50 gallon trees. My husband and I have been buying from them for over 25 years now and always feel confident in our purchases. We have an amazing orange tree that suddenly was covered with black tarry stuff. Friends offered many reasons for this - my favorite was air pollution. In taking a leaf to Regan's they were able to tell us it was a bug sucking the life out of our orange and essentially leaving his offering for us on our oranges. We sprayed with the recommended spray and are enjoying wonderful, juicy oranges!
