We can only observe the health of our plants above the soil. However, so much goes on just beneath the surface. Factors such as pH and microbial warfare can take a toll on the root system.
Watching your flowering buds start to put out foxtailing flowers often brings disappointment. After all, these buds are less dense, and therefore likely offer less of a yield.
Root zone health
Lights aren’t the only heat source in a growing room. Heatwaves can cause large spikes indoors and increase the temperature of the air, which can also have a detrimental and stressful effect on your plants. Greenhouses are also designed to trap heat. You’ll find out how to disperse all of this hot air in the solutions section below.
Cannabis breeders have created thousands of different cultivars. Through the process of selective breeding, they’ve created plants with hundreds of different tastes, shapes, sizes, smells, and effects.
Some creatures, such as parasitic nematodes, love to chew through roots and devour their contents. Their unrestrained grazing can cause leaves to become yellow and rot. This level of stress may also cause weed flowers to foxtail. You’ll discover key ways to keep your soil microbially healthy later on in this article.
Bloom times for these species are:
The ligule of yellow foxtail consists of a fringe of short hairs. Auricles are lacking. There are no hairs on the leaf sheath margin below the collar as in green foxtail. If the leaf sheath of green foxtail is pulled away from the stem, you can see fine hairs on the leaf sheath below the collar region and the leaf blades are flat and lack hairs. Giant foxtail sheaths are cylindrical or slightly flattened, with hairs at the margins.
First leaves are usually parallel to the ground.
Foxtails of the genus Setaria are summer annual grasses. Yellow, Setaria pumila, and green, S. viridis, foxtails consist of a complex of many biotypes. Yellow foxtail is found in the central-western region, Central Valley, South Coast, Mojave Desert, southwestern Great Basin east of the Sierra Nevada, and low elevations of the eastern Klamath Ranges, Cascade Range, and Sierra Nevada, up to about 3900 feet (1200 m). Green foxtail is found throughout low-lying and foothill areas of California, except in the Mojave Desert and Great Basin, to about 1000 feet (300 m). Giant foxtail, S. faberi, a species uncommon in California, is sometimes found in southeastern Sacramento Valley and the adjacent Sierra Nevada foothills, up to an elevation of 328 feet (100 m). Foxtails inhabit agricultural land and other disturbed areas. Yellow foxtail also inhabits turf. All grow in moist or dry soil and tolerate a broad range of environmental conditions.
Foxtails grow in loose clumps or sometimes singly. Stems are erect or bent at the base, but overall ascend upward. Mature foxtails range in height from 1 to 3 feet (30–90 cm) and branch at the base. Leaf blades are 4 to 15 inches (10–37.5 cm) long, and most have a spiral twist.
Roadsides, ditch banks, fields, pastures, cropland, orchards, vineyards, gardens, and other disturbed sites.
Flower heads are spikelike, bristly, and densely packed with flowers (florets). Giant foxtail flower heads range from about 3 to 7 inches (7–18 cm) long; yellow foxtail flower heads 7/10 to 3 inches (2–8 cm) long; and green foxtail flowerheads 7/10 to 6 inches (2–15 cm) long.
For ouch value, add to the list puncturevine, or Tribulus terrestris, right, DiTomaso said.
Also add hedgeparsley, or Torilis arvensis. According to a scary-funny UC Davis extension sheet, hedgeparsley is also called “the Velcro plant” because “it produces small, about 1⁄4 inch, burrs with little barbs that can seemingly stick to anything.” The hooked spines on bur chervil, or Anthriscus caucalis, also deserve a name from the sewing box.
To protect the rest of the body, Kay recommends taking your dog to the vet or groomer and asking for a “foxtail cut” that trims fur away from paws, making them easy to inspect. Inspect, we should, she stressed, after every trip to afflicted areas. Check paws, armpits, tail, eyes, nose, eyes.

The Dry Garden: Worst weeds for dogs
Second on my list of plants to yank on sight, and also singled out by DiTomaso, is the common lawn weed California burclover, above. This masquerades as clover but is a multi-limbed weed that can evade the mower by lying flat in grass, eventually studding it with small, stinging burs. So much for the picnic, never mind the puppy.
At the top of my list and also the lists of veterinarian Nancy Kay and UC Davis weed scientist Joseph DiTomaso are foxtails. Depending on where you live, foxtails might be any number of grasses with needle-like seed heads. After a spectacularly wet winter and a mild, unusually long growing season this year, foxtails are still standing — and at their most deadly: dry and brittle. The seeds are primed to embed themselves in your dog. In Southern California, DiTomaso said common foxtail-type grasses are wild barley, Hordeum murinum, and ripgut brome.
The problem with foxtails is that once they become embedded in your dog and begin traveling through it, they don’t break down, Kay said. Rather, the hooking design that enables foxtails to burrow in soil keeps them moving forward in animals. Some foxtails might enter the paw and eventually pop out the elbow. Foxtails that go up the nose might be swallowed and safely pooped out, but awns sucked in by a panting dog running full tilt with nose to the ground can end up in the lungs.
