For those of you who walk the Winterthur Garden regularly, you will notice some work taking place on our lawns. In September we will be renovating the turf in the areas around Sycamore Hill and the Sundial Garden because of the presence of an invasive grass. During renovation there will be an extended brown period followed by seeding, aeration, and irrigation. We may set up stanchions or ‘Garden Restoration’ signs so that guests and members don’t walk over the newly seeded areas.
- The invasive grass, known as wiregrass, can be identified by its light green color and long wiry stems.
- We are spraying the wiregrass with an herbicide in this key, late-summer time frame, because that is when it is most susceptible.
- We may have to bring in topsoil, re-grade, and re-spray to achieve the effect we are after.
- Grass seed should begin germinating in September and be established by next spring; there may be follow-up reseeding in the spring.
- Some of you may recall when we did this in the Sundial garden several years ago. It was a lot of work but ultimately effective at replacing the invasive turf with the more desirable cool season turf.
- This won’t be a permanent solution to the wiregrass, which is very aggressive, but it will substantially improve the situation.
We appreciate your patience as we undertake this renovation!
