Oppressive heat and humidity are a part of the late summer here in south Louisiana-- as much as good food and music are a part of our local culture. Despite the heat, gardening continues for those who can stand it.

Flower beds may not be looking their best right now. Our long growing season and abundance of insect and disease problems generally makes it unreasonable to expect all bedding plants to hold up from May through October.

As we move into August, gardeners need to focus on two important aspects of landscape maintenance. That's fertilizing and pruning.

August is the latest that we fertilize lawns, hearty shrubs, and ground covers. Now is the time to think about what you might want to fertilize and when you want to get it done as we get into August.

I don't know about you, but when it's this hot, I'm much less likely to spend a lot of time outside. Perfect time to focus on the plants growing indoors.

Indoor plants have requirements that must be met, and the most important one here is light. If you can't grow a plant where there isn't enough light, just don't grow it there.

The high temps with us from May through October their toll on the vegetable garden. Tomatoes, for instance, will set fewer fruit once it gets hot. Snap beans will produce poor quality beans.

On the other hand, for some vegetables, the hotter the weather, the more they like it! These hot season vegetables are ideal to plant in May and June.

Grown and used in cuisines around the world, basil is indispensable to Louisiana cooks as well.

Besides making food taste great, basil is really easy to grow and happens to be an attractive plant. Not only is basil a great addition to the herb garden, but with the numerous shapes, leaf colors, and attractive flowers, it makes a welcome addition to any garden.

Mulching is an easy-to-do, labor-saving gardening technique that all gardeners should take advantage of.

A mulch is a material, usually organic, that we use to cover the soil surface around plants. Mulching beds is an important part of sustainable landscaping.

Organic mulches, such as leaves, pine straw, ground pine bark, dried grass clippings, cypress mulch, and newspaper, are all derived from once-living materials. They also add beneficial organic matter to the soil as they decompose.

The Evolution Salvia is a cultivar of Mealycup Sage and it's been named a Louisiana Super Plant selection for spring of 2016.

It comes in two colors. Mealycup Sage is a native wildflower of Texas and it's well adapted to long hot summer weather. Evolution Salvia was chosen as a Super Plant selection because of the intense color of its flower spikes as well as excellent performance in trials at the Hammond research station.

Some of the most popular vegetables planted in home vegetable gardens belong to the cucumber family. Members of this family are called cucurbits. Many from this family can be planted this month, including summer squash, winter squash, mirliton, pumpkin, gourd, gugutka, watermelon, cantaloupe, cushaw, luffa, and, of course, cucumber.

All of these vegetables produce vines that crawl along the ground or climb. Summer squash is the exception as the vines are more bush-like.

One thing to remember is that both sexes of flowers grow on the same plant, so you don't need multiple plants.

Avoid using insecticides on your flowers in the morning, which is when your pollinators will be most active.

  The Easter Lily is a plant popularly used to decorate for Easter. Many of these plants are simply discarded after the holiday has passed and they finish blooming.

But Easter Lilies may be planted in your landscapes, where they will bloom year after year for many years to come. Once the flowers have all faded, you can plant your Easter Lily outside in a garden bed. Leftover Easter Lilies in stores and nurseries at reduce prices are an excellent bargain to obtain plants for your gardens.

Easter Lilies go dormant in mid-summer.

If you're planning to add some trees or shrubs to your landscape, it's a good idea to get this done as soon as possible.

The ideal planting season for hearty trees and shrubs here in the Baton Rouge runs from the fall into the spring and finishes around the end of March.

The reason we want to get these plants in the ground now, is the weather is cool, and we can expect another month or so of mild weather.

The transition from pot to ground is very stressful for the plants. Planting in hot weather increases the stress.
