Why You Should Never Let a Weed Go to Seed
Prevent weeds from growing in your garden and give them a boost of plant food with Preen Garden Weed Preventer Plus Plant Food.
A big reason that weeds are such effective invaders is that most of them are very prolific seeders. It’s not unusual for a single weed plant to throw off hundreds of viable seeds. If weeds are left to grow and produce new seeds, any that fall to the ground can live for years in the soil. Some can live for decades. That’s why the number one rule in winning the long-term battle against weeds is to stop them from growing at all.
Dealing with weeds you already have
If common spring-time sprouters like chickweed, purple deadnettle, dandelions, garlic mustard, and creeping speedwell have already flowered, a steady supply of summer weeds will be attempting to flower and set seed. Some of the worst summer seeding weeds include pigweed, purslane, thistle, lamb’s quarter, black medic, spurge, bindweed, Japanese knotweed, and assorted grassy weeds.
Pulling and/or digging is the most immediate, effective control. Just be sure to get roots and all or else many weeds will simply sprout new leaves from the roots left behind.
Be persistent, and you’ll eventually win – or at least gradually reduce the outbreaks by denying weeds from reproducing via seeds. Even if you can’t pull or kill all existing weeds, at least patrol enough to cut, hoe, or weed-whack any that are forming flowers or flower stalks.
Preventing future trouble
Bare soil only invites weeds, so it is best to add plants to bare spaces and add a few inches of mulch to your landscape beds to fill the space, leaving no room left for weeds.
Granular weed preventers such as Preen can go on top of mulched, planted beds to further stop new weeds before they have a chance to sprout and grow. Two to three applications per year can give season-long protection, depending on your climate and which type of Preen you use.

Controlling weeds that have gone to seed
Weed woes can get really ugly when those weeds have gone to seed. On the latest episode of You Bet Your Garden, host Mike McGrath gives the details on how to get rid of those weeds without planting next year’s crop of crab grass. Plus, your fabulous phone calls!
Question of the Week:
“I’m looking for advice on how to get an area of my garden back under control without using chemicals. I failed to keep up with the weeding in a section of my vegetable garden that is about fifteen by 30 feet. It had crabgrass, clover and a few other weeds that went to seed. I ripped them all out as best I could, but can’t get all the roots out—and I can see that a lot of seed has scattered on the surface of the soil. I wonder if covering the area with impermeable black plastic until next May would kill everything? Or maybe it makes things worse by keeping the area warm enough for the weeds to survive the winter?”

How to Cut Weeds After Seed Heads Appear
Weeds reproduce rapidly when they grow seed heads, and they can become an eyesore quickly as well as rob your garden and lawn of vital nutrients. Seed heads contain mature seeds that typically are spread by wind and insects. Ideally, weeds are removed before the appearance of their flowers that eventually release seeds. If some of them escape removal before they produce seed heads, they can be cut down. When you remove weeds with seed heads, you eliminate one of the biggest sources of weeds on your property.
Cut off weed flowers and seed heads using pruning shears, and dispose of them immediately. Cutting the flowers and seed heads rather than removing entire weed plants is ideal if you find weeds in your vegetable garden and don’t want to disturb your crops by yanking out whole weed plants. If the weeds contain large leaves that cover your plants, clip off all the weeds’ foliage so your crops receive more sunlight.
Cut weed plants to ground level with pruning shears or a lawnmower that has a mower bag. If you use a lawnmower, empty its mower bag into the trash immediately so that you do not inadvertently spread the weed seeds the next time you use the lawnmower.
Collect all of the cut weeds and seed heads with a rake, and dispose of them. Repeat the cutting process when the weeds grow and especially before they produce seed heads again.
