When the weather is hot and dry and there is no measurable rain, even rookie gardeners are aware that most plants will not survive without regular watering. Unfortunately, just giving them a squirt with the water hose isn't going to do much to relieve their stress. Wise gardeners give their plants the amount of water each one needs in ways that save time, effort and water.

It is important to use the right equipment. Much water can be saved in the summer by watering each part of the garden by a method appropriately suited for it. Briefly, hand sprinkling is fine for sprouting seeds, but all other watering should be done with conventional irrigation systems or drip systems. Reserve watering by hose for filling furrows and basins around trees and bushes, when these are not equipped with bubblers. (When you water this way, put the hose right down on the ground, and let the water sink in slowly.)

In the summer (or anytime for that matter), it is best to irrigate deeply but less frequently to encourage plants to send down deeper roots that are protected from the summer heat. Vegetables and annual flowers, though, will have to be watered more frequently since they don't produce deep root systems. For most grass lawns, since the roots are very short due to compact soil, water daily but just enough to keep the roots moist. See article “Lawn Water In Hot Weather”. Always water your garden in the early morning hours between 4:00 a.m. and 8:00 a.m. to reduce water evaporation.

One note: try not to water if it is raining. More plants die from over-watering than from under-watering. Plus, even if it doesn't harm your plants, you are simply wasting the water.

Be sure to give special care to plants in containers. Plants in containers often suffer at this time of the year. Water them frequently, especially plants in terra cotta pots. These porous containers “breathe” allowing water to evaporate faster than plastic or glazed ceramic pots. If you take good care of your plants in summer, you will be rewarded throughout the rest of the year.

The pesky little insect has ruined countless hikes, BBQ's and campouts. This vector has literally killed millions of people throughout history, and still affects millions around the world today. As daunting as this sounds, there are steps you can take to co-exist and stay healthy.

What attracts the mosquito? After 30 million years of evolution, the mosquito has perfected its hunting skills. The mosquito uses three sensors to attract its prey:

• Chemical sensors: Mosquitoes sense carbon dioxide and lactic acid up to 100 feet away. Unfortunately, we give off these gases as part of our normal breathing.
• Visual sensors: Clothing that contrasts with the background enables the mosquito to "zero in" on you.
• Heat sensors: Mosquitoes detect heat, so they can find warm-blooded mammals very easily.

The best thing you can do to control mosquitoes is to use a mosquito repellant with DEET and eliminate standing water around your home. A mosquito can lay up to 250 eggs at one time in still water, and they can hatch as fast as 7 days. Check your gutters frequently for collected water (especially if they sag and aren't level), along with birdbaths, buckets or boggy areas of the garden.

Burning citronella candles, using an electronic bug zapper, or spraying surfaces near entertainment areas with a mosquito barrier spray like Green Light Spinosad will also help kill, or at least repel, mosquitoes. We also highly recommend using Mosquito Dunks if you have areas of standing water that you can't drain.

Diligence is your best protection. Stay indoors at dawn and dusk hours, wear pants and long-sleeved shirts if possible, avoid any standing water, and repair broken screens.

Although it can be a constant battle, by incorporating the use of insect repellents and breeding prevention (eliminating standing water), mosquitoes and the diseases they carry can be reduced, making the outdoors more accessible and enjoyable for everyone.

Grasshoppers are among the most difficult insect pests to manage in the garden. When numbers are low, they can be hand-picked and squashed. Floating row covers and other protective covers provide some protection if their numbers are not high. However, grasshoppers will eat through cloth or plastic row covers if they are hungry enough.

Most grasshoppers are general feeders, but they prefer young, green plants, especially lettuce, beans, corn, carrots, onions, and some annual flowers. Grasshoppers do their damage by chewing and can remove large sections of leaves and flowers in one sitting, sometimes devouring an entire plant. An odd grasshopper here and there is nothing to be alarmed about, but should you face a full invasion, there are some steps you can take to combat this destructive pest.

The best way to control grasshoppers is to apply a bait containing carbaryl around the borders of your garden. Make sure to re-apply baits after any period of rain. For non-edible plants, you can also use a spray directly on the plants. It usually helps to do a repeat spray every couple of weeks until they leave your garden. Make sure to spray late in the evening or early morning when bee activity is lower; you don't want to kill our important pollinators.

The leaves on some of my plants are starting to turn brown. How can I tell if the cause is lack of water, or salt or chemical damage?

Answer:

That's fairly simple.

• If a plant is too dry, the tips of the leaves will turn brown. The longer without water, the farther down the leaf the burn will extend.
• If a plant is suffering from salt damage, the entire leaf edge will appear brown or dry.
• If it's chemical damage, the foliage will generally have burn spots all over the leaf surface.

And here are the usual causes:

• If a plant is too dry, it needs deeper or more frequent watering.
• Salt burn is most often caused by excessive fertilization.
• Chemical damage results from weed killer drifting onto a plant, a chemical solution being mixed stronger than label recommendations, or a spray being applied to (or too near to) a plant that is sensitive to that spray.

Please note that all three scenarios have man-made causes.

No doubt you're seeing these riotous shrubs and small trees in bloom right now! Sunny and hot will continue to be the forecast over the next couple months.

Some plants (and people!) grow weary and stressed when high temperatures persist day after day. Crape myrtles, on the other hand, thrive under these conditions, making them valuable flowering shrubs or small trees in the landscape. Whether trained as standard or multi-trunk trees, Crape myrtles make beautiful specimen or accent plants. Showy crinkled flowers are abundant throughout summer, with colors ranging from the reds to pinks, purples, and white. These gorgeous shrubs are wonderful in any sunny spot where summer color is needed.

For desired size and shape, prune in early spring. Don't worry too much about your pruning skills, as crape myrtles bloom on new wood. However, it is important to deadhead as blossoms fade in order to encourage continuous bloom. Crape myrtles are long-lived, drought tolerant and relatively pest free, although sometimes aphids and powdery mildew can be a problem. The handsome bark and fall leaf color just add to an already stunning plant!

Enjoy the show!
