Emma Erler, host of Homegrown NH and lead horticulturist at Kirkwood Gardens at Squam Lakes Natural Science Center, has also been busy with the hoses, and she has some suggestions for keeping your garden hydrated. She says the first step is to keep track of how much water the garden is receiving naturally. “I think everyone should have a rain gauge in their garden,” she says.
