Need some help please! Have 2 spots where I've planted brown top millet for dove season. It is now 6 weeks old. We've had unusual rain in that for the last month is goes for a week or more w/out rain and then 2-3 days of thuderstorms. The millet is very light green but is coming in very well. It just looks like it should be a little farther along than it is. It is now about 4-5 inches high. My question is: Should I fetilize? If so, when? Any suggestions on what to use to fertilize?
