Preemergent can thwart weeds before they get growing
Q: I can鈥檛 believe the number of baby weeds that are already growing in two of my rocked beds. It鈥檚 still so cold out and I have a hard time working in the cold outdoors. I鈥檓 wondering if there is some sort of weed preventative that I can apply to help combat these pesky weeds. Help! 鈥� D.W., sa国际传媒官网网页入口
A: You are correct that if you look, you can find lots of baby weeds already growing.
In fact, I just pulled a crop of what I know as flixweed out of my back yard last weekend. The most mature were at least a foot and a half tall already. They are showing up in a spot that is warmed by a wall and some of the recent light rains we had were just the ticket to make them want to grow so rapidly.
There are products available that you can apply to prevent weeds and some of the weedy grasses we鈥檙e known for from germinating and in turn growing to maturity. They are called preemergents. Using the internet, search for preemergents and you鈥檒l unearth a whole host of products.
You could also reach out to local nurseries to see what products they鈥檇 offer to combat the weeds. Most big-box stores carry a product named Preen and it鈥檚 simple to use.
Just be aware preemergents do nothing to kill or maim an already growing weed or weedy grass. Preemergents work by either creating a crust at soil level that keeps a seed from being able to complete germination or once the product is applied and watered in, it wraps around any seed it finds, again keeping that seed from germinating.
Don鈥檛 apply a preemergent anywhere you are going to want to plant anything by seed later this year. You would not be very successful.
Fewer seeds germinating and sinking roots, that is what you鈥檙e aiming for. You will need to pull all weeds you have growing before you apply any preemergent products. If the weed is actively growing happy and green, the preemergent will not harm it in any way.
If you leave the already growing weeds and consider hunting them with a weed killer, the weed killer could hang around in the soil or move through the soil and harm any treasured plants you might have growing nearby.
I really suggest biting the bullet and plucking the young weeds rather than applying a weed killer.
So during the day when the high temperature reaches its peak, get out there and pluck away. Get in the habit of having a watering can nearby so you can water the weeds first and that will make them easier to pull. Make sure that you tidy up completely. Don鈥檛 leave any weed carcasses lying around. They have to go in the trash.
Like you, I don鈥檛 like to have to work outdoors in the cold, but if you don鈥檛 get this young crop of weeds now, you鈥檒l have more to deal with as the season progresses.
Happy hunting and preventing, and Happy Diggin鈥� In!
