Gardening tips for June
June is a great time to be outside: the weather is warm, but without the prolonged heat and humidity that’s sure to follow. Annuals and perennials are blooming, and if you’re lucky enough to have planted an early edible garden, you can harvest salad greens, spinach, peas and strawberries.
Even if you’re behind schedule with your gardening plans, there’s still time to do what you need to do before the dog days of summer arrive, so take the time to relax in your garden and revel in its beauty.
