Even the hardiest plants need a little help putting down roots in new locations. Sprinkling the foliage doesn’t nourish the roots, the plant’s nerve center. You must deliver water to the root ball below the ground, or your plants will be stunted and short-lived.

Try this instead: Place the hose at the base of new bushes, trees, and plants and let the water trickle out for 20 to 30 minutes, twice a week (more during hot spells), for 4 to 12 weeks. Or snake a soaker hose ($20 for 50 feet) through your beds, which will deliver slow and steady water to roots.
