I planted bluebonnets last fall. When should I expect to see them?
Despite this cold winter, bluebonnets have germinated. They are now about 4 inches in diameter and an inch or two high. They can be recognized by the flat appearance at this stage and oval leaves.
They should start to grow once the weather begins to warm up, and you should have blooms by mid-April. However, do not be discouraged if yours do not sprout this year. It can take up to five years for the seed to germinate.
I have this weed that puts out runners that grab on to my clothes when they touch it. What is it, and how do I get rid of it?
This sounds like sticktight (gallium aparine), also called sticky Willy, or the velcro plant. It creeps along the ground and over the tops of other plants, attaching to them with small hooked hairs growing out of the stems and leaves.
The stems can reach up to 3 feet in length. The best way to control it is simply to remove the plants before they flower and produce viable seed. It can be removed by hand hoeing or weed pulling. This is best done in the early spring when the soil is moist. Installing and maintaining mulch also helps and eases the removal of plants that do become established.
Cutting it back to 2-3 inches is generally not effective and will actually cause increased growth. It will die out once the hot summer arrives. While chemical controls are generally not recommended, it can be controlled with post-emergent herbicides such as oxyfluorfen, glyphosate, quinclorac or diclobenil.
