4 of the most common weeds you should be watching out for in your garden

No matter how hard we try, weeds will always come back. They’re part of the cycle of nature, growing throughout your lawn and even into the raised garden beds you worked so hard to build. And it doesn’t help that there are so many different types of weeds. The good news is: They can almost always be removed! Depending on the amount, it may take a little more work. But an invasive plant isn’t the end-all-be-all of the gardening season. Here are some of the most common types of weeds you’ll find around your yard, how you can identify them, and how you can remove them.

Thistle weeds

Thistles are an invasive weed most known for their bright purple heads and prickly greens. At any given point in your life, chances are you’ve stepped on one of them running through the yard — and it’s not a fun experience. There are about 200 species of thistle around the world, ranging from moderate to heavy in invasiveness, and some are even edible! In most circumstances, though, you don’t want them taking over your yard. If you notice a thistle infestation, here’s what you can do.

How to remove them from your garden

As far as removing thistles goes, you may not want to — at least not fully. Although there are some invasive species that can take over, there may be thistles that are native to your area and serve as an important part of the habitat. The nectar of native thistles is often used as a food source for the local bee and butterfly populations, as well as other pollinators. With this weed, it’s important to research the variety to make sure that you aren’t fully wiping out something that may be necessary to your area’s environment.

That said, it’s possible to relocate some of the native thistles to a dedicated “thistle garden,” if you want to avoid fully eradicating them. They do still grow fast and plentiful and are often inconvenient to have in an active area of the yard.

For thistles that you want to remove entirely, you should look for a weed or grass killer that’s safe for your lawn (and any surrounding plants). The spray should help kill the thistle quickly and kill it down to the roots.

Sticker weeds

Commonly known by their burs, sticker weeds are annuals that grow in cool weather before the temperatures warm up for the season. There are a variety of different sticker weeds you can find in your yard and garden, including:

  • Burweed
  • Bur clover plants
  • Field sandbur sticker plants
  • Grass stickers
  • Lawn burs

These plants are often hard to spot before you get snagged on them, and you may have even seen your indoor/outdoor pets come in with some stuck in their fur. Many sticker plants can be identified by their bright green hairy leaves and low-growing nature.

How to remove them from your garden

Because they’re low-growing, removing sticker weeds from your garden is a bit of a chore. They grow fast across an area, getting out of control rather quickly. It is possible to remove these by hand, either by pulling them up or digging them out with a shovel. This is, however, the hardest way to get the infestation under control.

Your best bet will either be to use herbicides or natural weed killers. You want to make sure that whatever you use, it’s as safe as possible for your lawn and the surrounding garden beds. No matter which option you go with, you should follow the directions as best as possible to effectively get these plants out of your yard.

Grass weeds

Grass weeds are another blanket category that include a wide variety of invasive plants, including:

  • Common ragweed
  • Crabgrass
  • Creeping Charlie (or ground ivy)
  • Foxtail
  • Red-root pigweed
  • Stinging nettle

And these are just a handful. Grass weeds encompass a lot of the common weeds you’ll find growing in your yard, and the way you handle them might differ depending on the kind you’re dealing with.

How to remove them from your garden

To figure out how to eradicate a weed from your garden, you need to first identify the weed. For example, crabgrass is known for its pencil-thick leaves that grow straight and outward from the middle. The best way to get crabgrass under control is with a mixture of lawn fertilizer and pre-emergence herbicides. On the other hand, stinging nettle (identified by green sawtooth leaves and the welts they leave behind) should be pulled up and bagged by hand while wearing protective gloves.

Each weed should be handled differently, but in general, it never hurts to have a spray weed killer on hand that’s safe to use on your lawn.


Dandelions are one of the most well-known weeds you can find, popping up everywhere from homes to parks to schoolyards. And although they’ve got beautiful yellow blooms, they’re a fairly invasive plant that can take over quite quickly when left to its own devices — especially because of their puffy seedheads, which spread easily around the yard when blown or moved around.

That said, dandelions are edible and have a variety of purposes, including tea made from the roots and salads made from the greens and the blooms. The only part of the plant that isn’t edible is the stem, so if you’re tempted to pick some for a fresh spring treat before removing them, make sure you don’t put the stems in your meals!

How to remove them from your garden

Dandelions have taproots that can be up to 15 feet long, which can make them particularly difficult to remove. It unfortunately isn’t as simple as yanking on the stem and hoping for the best, or letting the lawnmower run them down.

The best way to remove dandelions from your garden will either be spraying them or digging them up with a shovel. You want to make sure you use a spray that’s safe for your lawn and any surrounding plants since you don’t want to harm your gardens in the process. When spraying, make sure to rough up the dandelions in some way first (kicking works well!) to open wounds that will allow the spray to work more effectively. Alternatively, if you’d rather dig them up to avoid any risk to your other plants, you should make sure to get at least two inches of the taproot, otherwise, two dandelions will return in their place.

Keep in mind, too, that this list isn’t exhaustive. The types of weeds you deal with will depend largely on the area you live in, what’s native, and what’s non-native and invasive. The best way to handle weeds is to prevent them from growing in the first place by taking care of your lawn, mowing regularly, and keeping things healthy.

Blazing stars will fill your summer garden with color: A liatris care guide
Growing and caring for liatris
Tall purple liatris (blazing star) with butterflies

There are many wonderful plants you can add to your summer flower garden for stunning color, from tall and bright sunflowers to short and sweet zinnia. If you’re planning your garden now, you should definitely consider adding liatris, also called blazing star, to the mix! This tall, drought-tolerant, native perennial has stunning purple flowers. It’ll even attract butterflies. Here’s everything you need to know about planting and caring for liatris.
Planting liatris
You can plant liatris bulbs in the spring or fall, but you can transplant mature plants during any season. Choose a location with full sun and well-draining soil to plant your liatris in. Blazing stars can tolerate some light shade, but they won’t thrive unless they get at least 6 hours of sun each day. Spacing is important when planting liatris, as they can grow to 2 feet high and 1.5 feet wide. Plant your liatris bulbs 12 to 15 inches apart so they have plenty of space to grow.

In addition to having well-draining soil, it should also be average or poor. Many plants prefer soil that's rich with organic matter, but liatris has an unusual quirk! The flower stalks will sometimes bend or flop over if the soil is too rich.

Take advantage of hydrangeas’ color-changing quirk – how to get beautiful blue hydrangeas
Make your soil acidic to turn your hydrangeas a beautiful blue color
Hydrangeas with blue flowers

Hydrangeas are known for two things -- impressive, showy flowers and their tendency to change color based on the pH of the soil. This makes them highly appealing, but also unpredictable. If you don’t take the soil into account, your bright blue hydrangeas could turn out to be pink or purple instead. With careful planning, you can take advantage of this quirk to ensure your hydrangeas are the striking shade of blue you want them to be.
Getting started
First, check what variety of hydrangeas you have. Not all hydrangeas change color! Bigleaf hydrangeas, especially the mophead and lanceleaf cultivars, are the ones that change color. However, white hydrangeas of any variety will not change color.

Test the soil’s pH before you get started. This lets you know how much you’ll need to change it, or if you need to change it at all. If your soil pH is already between 5.5 and 4.5, it’s acidic enough to turn your hydrangeas blue.

Texas sage: This colorful shrub can withstand almost anything
Here are tips on caring for Texas sage

If you’re in need of a beautiful, hardy shrub that can withstand almost anything, then Texas sage is a great place to start. With silvery leaves and purple flowers that resemble true sage, this robust shrub looks amazing on its own or as part of a larger garden. If you want to add this lovely flowering shrub to your garden, then you’re in the right place. Here’s a simple care guide to help get you started.
Planting Texas sage
Texas sage is tolerant of poor soil, heat, and cold, so it’s typically not an issue to grow it outdoors. However, if you’re lacking in space or want to liven up your home, it can also grow in a container. In fact, its tolerance of poor soil makes it easier to grow in a container than many plants, as it doesn’t need fresh soil as often. A container that's around 12 inches in diameter is typically big enough for a Texas sage plant.

Whether indoors or out, you’ll need to make sure it has proper drainage. The most common problems with Texas sage come from overwatering or poor drainage, but you can avoid this by testing your soil’s drainage or choosing a container with drainage holes.
