-WATERING!!!! - most likely your main task right now. Water deeply, less frequently. You
want the soil moist about 3-4" down. Morning is the best time, but evening may have to do. Water your containers until liquid runs out the bottom.
-It's best to water most plants from the bottom - especially such things as hydrangeas where the large flowers will get too heavy if watered from the top.
-Keep seed pods removed from repeat blooming daylilies.
-Deadhead perennials - you may get a second flowering.
-One last chance to pinch back your mums. Don't do so after the second week of July.
-There seems to be an abundance of poison ivy this summer. I'm finding little seedlings everywhere and was getting tired of washing my gardening gloves every day. Keep a box of disposable rubber gloves handy. Make note of where the poison is, then wearing the rubber gloves, go out and pull it all at one time.
