April is a wonderful time to enjoy gardening. Azaleas are putting on their spring show and many types of citrus trees are blooming. Trees are putting out their new foliage that is such a delicate green. Add the pleasant temperatures and you have a strong invitation to get out in the garden.

Hopefully, you have already planted the trees and shrubs that you want to plant for the year and are ready to concentrate on annuals, perennials, vegetables, and lawns. Here's a checklist for keeping up with the chores while enjoying the pleasures of April.

Here's a checklist for keeping up with the chores while enjoying the pleasures of April:

- The Galveston County Master Gardeners will conduct a "Grafting Fruit & Nut Trees...The How To’s for Homeowners" workshop on Saturday, April 9, from 9:00 a.m. to 12:00 noon at the Galveston County Extension Office, 5115 Highway 3, in Dickinson. The workshop will be presented by Master Gardeners Herman Auer, Terry Cuclis, Bert Janke and Anna Wygrys who hold the title of Master Gardener Propagation Specialists in addition to Texas Master Gardeners.

A variety of grafting techniques for fruit and nut trees will be demonstrated including wedge grafting, T-budding, 4-flap, and inlay bark. Program participants will have the opportunity to practice grafting. There is no registration fee but class size is limited and pre-registration is required (by phone at 281-534-3413, ext. 6 or by e-mail at GALV3@wt.net).

- The Spring Pecan Field Day will be conducted on Monday, April 11, from 4:00 p.m. to 5:30 p.m. Grafting demonstrations will be provided throughout the time period by members of the Extension Fruit and Pecan Committee. Graftwood from several varieties of pecans will be available (a donation of $1.00 per stick is requested). Graftwood of several fruit trees will also be available.

The Field Day will be held in La Marque in the Pecan Orchard at the Carbide Park (which is located on the North side of FM 519 about one mile West of the intersection of FM 519 and the I-45 Gulf Freeway, Exit #10). A printable map can be downloaded from the web site address at the end of this column (click on "Extension Educational Programs" link) or contact the Galveston County Extension Office for additional information (281-534-3413, ext. 6 or GALV3@wt.net).

- One tendency shoppers have is to buy transplants of summer annuals only with open flowers. Young transplants that have few or no flowers may be a smarter purchase since these plants will grow larger before flowering. The result will be a more impressive floral display in your home gardener.

- One warm season annual that many folks set out too early is periwinkle. These are warm weather plants. Periwinkles planted before mid-April are much more susceptible to a fungal blight disease that can wipe out a whole bed of plants. Delay planting periwinkles until the weather is consistently warm.

- Select caladium tubers while there are ample stocks available but do not plant caladiums too early. They typically should be planted from April into early May. Caladiums need warm soil temperatures (at least 70 degrees) for best growth.

- Wait to fertilize azaleas until after the major bloom season is finished. Consider using a fertilizer specially formulated for azaleas which provides plant nutrients in the right ratio and also helps to maintain acid soil conditions needed by azaleas. Because azaleas have a shallow root system, many gardeners have found it to be beneficial to apply several light fertilizer applications over time rather than all at one time.

- Periodically check your lawn mower blade for dullness and examine a few blades of freshly mowed grass. Use of a dull blade will result in the mowed (better descriptions would be torn and "whacked-off") end of leaf blades and stems being stringy and ragged. These tips will also develop a brownish discoloration shortly after being mowed. In addition to looking unsightly and causing the mower engine to labor harder, lawn grass cut with a dull blade is more susceptible to certain diseases.

- Mid-March to the first week of April is the recommended time to fertilize lawns. A good way to determine when to fertilize is to wait until you have mowed the predominant lawn grass twice. If you fertilize too early, you will be fertilizing the winter weeds! This allows time for the grass to green up naturally without pushing it into growth.

This practice results in a turf that is more resistant to summer stress. Use a 3-1-2 ratio fertilizer (such as 15-5-10) and distribute with a broadcast (cyclone) or a drop-type spreader. Uniform distribution is essential to prevent light and dark streaks in the lawn. For better distribution, divide the fertilizer into two equal applications. Spread one application lengthwise and the other crosswise.

- Use caution when applying the popular "weed and feed" type lawn fertilizers. Some weed and feed products can be used near shrubs and inside the drip line area of trees while other types of weed and feed products carry a strict warning to not apply the product near such landscape plants. It depends on the type of weed killer (or combination of weed killers) that is contained in a given product. Be sure to carefully read the label and never exceed the rate stated on the label.

- Pinch back leggy bedding plants to encourage side shoots. Pinching stops the terminal growth, thus resulting in bushier plants and more flower buds.
