If you are planning to go away for any period of time this summer, remember new trees, shrubs and perennials will need regular, deep watering throughout the summer and fall months to establish good root systems. Consider setting up drip hoses on timers or use ‘tree gators’ to ensuring the water continues to get where it is needed. Use rain gauges attached to the system to prevent wasting water (and overwatering plants) if we continue to get regular rains.
If you're going away on vacation this month, be certain your new plantings will get adequate water.
