You're fine. Both the 1:3 and 1:4 ratios are within the range of naturally occurring concentrations in flowering plants. Here's some data from the Lousiana Ornithological Society Newsletter, March 2003, written by Dennis Demcheck. The 3rd number is the average percentage. The higher percentage may be preferred by birds but the number of total visits to a feeder may be higher with the lower percentage.

RE: cattleya orchids... (Follow-Up #9)

Some of the growers I've talked to swear by Neem oil spray for scale and lots of other problems. I've used that from time to time. For a severe scale problem like Boisduval scale a systemic like imidacloprid is usually recommended. My problem with this came as a "gift" attached to a plant I bought from a grower. I lost a lot of plants before I learned how to treat it. I hope you never see that problem.

This might help they are made out of 3/8 rebar from Home Depot. They are easy to bend and I first put them togather with electricl ties and later wired them togather. They are about a 1 1/2 feet in the ground work really good even in high winds.
