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.

The next several months are a popular time for adding new beds of shrubs, ground covers, and flowers to the landscape. It's also a popular time for reworking and replanting existing beds you may have.

When you're dealing with beds right next to your house, this work can affect your home's termite protection.

Houses are typically protected from subterranean termite damage with chemical barriers in the soil. To protect the structure, the soil immediately next to the slab or piers is treated with a long-lasting liquid termiticide. The presence of this chemical in the soil provides a protective seal that prevents termites from tunneling through the soil and entering your home.

This protective treated soil should never be disturbed or altered. Also be careful with mulch, as mulch can provide a bridge past the treated soil which termites can use to enter your home.

February, March, and April are popular months to fertilize. There's some real confusion about what fertilizers are and why we use them. That confusion comes about because of the terms we use, such as "plant food" and we're "feeding" them.

Instead, fertilizer contains the elements the plants need to make food. Scientists have found there are 13 elements in the soil needed by plants to grown healthy. The elements used in the greatest quantities are nitrogen, phosphorous, and potassium.

As a gardener, you must understand a fundamental principle of how plants grow. Plants consume light to provide the energy they need to power and build their bodies.

Plants are solar powered organisms. They use light energy to build sugar out of carbon dioxide and water. This sugar, along with tiny amounts of minerals absorbed from the soil, is used to build the body of the plant and run its biological processes.

You must learn the light preferences of a plant and provide that light as closely as possible. Nothing matters if you don't get the light right.

Pansies blooming in Shreveport, La.

Every year, Louisiana gardeners see amazingly beautiful beds of pansies, violas, dianthus, snapdragons, and many others, whose peak blooming season is around April. Wanting to create the same beauty in their gardens, they go out to the nurseries in April and purchase these plants and plant them in their gardens.

Invariably, they're disappointed when their plants never achieve the spectacular results they saw in others people's gardens.

There's a reason for this. The most spectacular mid-to-late season displays of cool season bedding plants were planted in the fall. Cool season bedding plants planted in April can not and never will achieve the beauty of those planted earlier.

They key to outstanding beds of these plants is early planting. And know what? It's not too late!

Early February is an excellent time to prune repeat flowering roses. And now is the time to get this done if you haven't pruned them already.

Repeat flowering roses are those that bloom heavily in the spring and early summer, then intermittently through the summer, and heavy blooming again in October through early to mid December.

Roses are pruned for a variety of reasons. One of them is to stimulate new growth. Another reason is to control the size of the bush.

Virtually all trees in our landscapes will need to be pruned during their lives, particularly in the first two decades after planting.

Sometimes a tree may be pruned in some way to help it, such as in dealing with storm damage, reducing limb weight, removing dead limbs, and stopping the spread of diseases. More often trees are pruned to adapt them to our urban environments, including keeping limbs from coming into contact with power lines, rubbing against the home, hanging too low, or obstructing views.

Home gardeners can carry out minor pruning, especially to train younger trees before they get large. Ask yourself why you think the tree needs to be pruned.
