Getting your Maryland feeder right
The recipe is the same everywhere: four parts water to one part plain white sugar. No red dye, no honey, no brown sugar. In Maryland's warm months you will need to change the nectar every two to three days, and daily once daytime highs pass 88°F — fermented nectar and black mould make hummingbirds ill.
