Make a Spectacular Garden on a Budget

Gardens may require attention and care, but they shouldn’t burden you financially. Choosing where to build a garden, knowing the types of soil to use, and growing the right plants for your climate can help you avoid costly mistakes.

Whether you adore the practicality of fruit and vegetable gardening or the beauty of ornamentals, these tips will help you establish a thriving and budget-friendly garden.

Name That Flower

This native perennial of Texas and Louisiana grows in sunny areas of well-draining sandy loam.

It can grow up to 5 feet tall on wiry, soft, wand-like stems, which end in clusters of white flowers that slowly fade to pink and occasionally maroon.

Although some consider it a weedy plant, others love that it establishes colonies quickly and blooms reliably for three to four months.

Garden Nearly Year-round
In Southeast Texas
By Valerie Depew
Harris County Master Gardener

It's here – fall in Harris County, with the official start of winter just a few weeks away.

For most of the world, fall is a time for gardens to sleep as we plan for spring. But as others put their perennial beds under mulch and protective coverings, gardeners in southeast Texas are dressing up flower beds with colorful winter annuals and planting perennials for spring and summer color. 

Vivid flats of pansies, violas, dianthus, snapdragons, alyssum, cyclamen, and ornamental kale or cabbage look great tucked in masses in the landscape or used in containers to brighten a patio or yard. There is nothing better to enhance your home entrance than a fresh pop of winter color! Look for healthy transplants from your local nursery and plant them with extended-release fertilizer to keep them going strong. 

Late fall is also an excellent time for growing perennials and planting trees in Texas. When planted in fall, woody perennial herbs grow modestly through winter while establishing a healthy root system. 

Let's not forget about the herbs that thrive in colder weather, including parsley, oregano, thyme, lovage, lavender, mint, rosemary, and cilantro. These easy-to-grow plants are practical to have around all year in kitchens and porches!

Keep in mind that a freeze will still be deadly for some of the plants mentioned above, particularly some of the annuals and tender perennials. If the winter remains mild, then a cloth or appropriate cover will allow many plants to survive cold snaps.

They will also help you choose the right tree and decide where to plant it, plus provide tips for keeping it healthy.

When it comes to maintaining an area as vast as Mercer, every volunteer matters. With more than 400 acres, Mercer relies on a team of volunteers to help manage its gardens, the Mercer Botanical Center, the Horticultural Propagation Center, and the Harris County Precinct 4 Prairie Dawn Preserve.

What's most impressive is that these volunteers contribute approximately 14,000 hours annually!
Starting in January 2021, monthly Mercer volunteer orientations will be available to those interested in assisting or learning more about Mercer. 
These orientations will be from 6 p.m. to 7 p.m. on Jan. 7, Feb. 11, March 4, and April 8.
