Foxtails in an ugly mess of laurel, 4th Street between I and J, from the alley
Fox tails are beginning to ripen their seed all over town, mixed with cheat grass and other weeds, and infesting lawns. It is a well-known sticker seed, sticking in pets’ fur and working its barbed seeds into their flesh. Like cheat, it is a major fire hazard. Its name describes the seed heads, looking like a fox’s brushy tail.

Like nearly all annual grasses, it is easiest to see and pull when it has seed stalks. Unlike many of them, it grows full size-heads even after being mowed. It stands out clearly in a lawn as it starts to ripen, yellow-green and ugly against the darker green of lawn grass.

So does annual rye, but it is a lot smaller and nicer annual grass whose seeds don’t stick and can be smothered with an inch of compost because they are small. Fox tail seeds are large and can come up through several inches of compost; heavy leaves are more effective, and a good way to stop them in flower beds. But even light leaves can soften the soil and make it easier to pull weeds.

It is hard to pull mowed foxtails when they are dry in dry ground; water it and pull it before it gets to that point. Gather up the stalks in each clump and give it a good yank; you will clear it out more quickly than you would think.
Wild lettuce on city property
Wild lettuce is also starting to bloom all over. It comes in several varieties, some uglier than others, all looking much like a dandelion with a tall, thick stalk. It is the ugliest of weeds that spread their seeds on the breeze, and can grow head-high, adding to fire hazard. The time to stop it, like all such weeds, is before those seeds ripen and become a nuisance rather than just an eyesore, spreading those seeds to the neighbors.
It sticks hard in dry ground; to get the root, you will usually need to water the ground. If you break or cut the stalk above the crown, it will grow more flowers ASAP.
Canada thistles are also showing up; they are much like wild lettuce except that they have sharp spines and blue flowers. These can be cut below the crown with loppers or even just kicked out of the ground; the spines can make hand-pulling difficult, but by the time it is sending up flowers, it has little food in the root; young plants are easy to pull.
Take all seeding lettuce, dandelion, thistles, and other composites to a commercial composter; the seeds will continue to ripen and fly after they are pulled.
The best prevention for weeds is leaf mulch, which doesn’t make a good weed seed bed until it becomes soil. What weeds do grow in leaves are easily pulled because the soil is fed and loosened. Leaves should be cleaned off lawns, pavements, paths and buildings, and spread on soil, to feed and protect it.
