Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Please forgive us, but Mr. Smarty Plants has been overwhelmed by a flood of mail and must take a break for awhile to catch up. We hope to be accepting new questions again soon. Thank you!

Title: Potting soil used in Wildflower Center nursery
Answered by: Barbara Medford and Sean Watson

QUESTION:

I recently purchased several beautiful little plants at your Fall plant sale and notice how very happy and healthy they all are! Please tell me if you mix your own potting soil and what your potting mixture consists of. Also, do you use different mixtures for the different types of plants you grow? Thanks for this wonderful resource!

ANSWER:

We e-mailed the nursery manager at the Lady Bird Johnson Wildflower Center, Sean Watson, and got this immediate response:

We use the Gardenville "Container Mix" right now (Texas Disposal Systems produces the stuff). It is good compost pure and simple. It also has composted pecan hulls that help it to drain better, not become too compact (adds texture), and adds nutrients over time. We used to use Nature's Way Resources out of Conroe, TX, which I thought was a better compost, especially for containers (50% composted leaf mold, 50% composted hardwood mulch), but we decided to try this mix because it costs half as much and is local versus the gas we purchased for the trip from Conroe for the other. Just tryin' to lower our carbon footprint. We use it for all species, but sometimes cut it with sand for more xeric plants. Using compost also means less watering than with our previous mix (holds water more effectively).

Sean and his crew of staff and volunteers is an outstanding reason why our Plant Sales are so successful, and we thank you very much for your kind words.
