How Can You Get Rid of Poison Ivy?

Poison ivy is among the toughest weeds to remove from your property since it easily spreads. To completely kill it, you'll need to take strategic approaches like organic or chemical treatments.

1. Organic Treatment

When dealing with problematic plants and weeds, you can try organic methods of control. You'll need to tackle this plant from the root to ensure there isn't any chance for regrowth. Unfortunately, pulling it out isn't an easy task since it causes discomfort and allergic reactions that can leave you in pain.

As such, you'll want to wear protective gear if you are bent on uprooting this plant. You'll need to ensure each part of your body is well covered to prevent any direct contact with poison ivy. Even after removal, you should ensure you avoid touching the gear you've used since some of the ivies can be transferred to your skin.

2. Chemical Treatment

Chemical methods of removing ivy are more effective compared to organic methods. If you want to ensure that this weed won't regrow, using chemicals is the safest bet. Nevertheless, you might have to apply the concentrate several times to completely kill the plant from the root. You'll need to apply the solution on the leaves from where they will permeate the entire plant to kill it and prevent it from growing back.

What's the Best Time to Treat Poison Ivy?

If you are uprooting this plant, the best time to do so is after it rains when the ground is moist or wet. This is because the soil will be easy to dig around, making it easier to remove them. This weed starts to sprout around May, and removing it after it fully develops is the most effective way to ensure it doesn't regrow.

When the Ivy is mature, the leaves will transport the chemicals much faster to ensure the plant dies from within. Keep in mind killing poison ivy is mostly a long-term process since it is resilient and can keep coming back. Plus, you wouldn't want to apply the chemical during a rainy day since the water will wash it off from the leaves.

Factors to Consider When Choosing the Best Brush Killers

1. Types of Brush Killers

Your brush killers will come in one of two forms; herbicide concentrates or ready-to-use sprays. As the name suggests, ready-to-use sprays are formulated to the ideal potency, meaning you only need to apply them to kill the weeds.

On the other hand, herbicide concentrates are formulated with a lot of strength and require you to dilute them before using them. Therefore, they are more suitable for large areas since a small amount can go a long way.

2. Systemic vs. Contact

Systemic herbicides are the ones designed to kill the weeds from the leaves to the roots. They do this by penetrating the leaves and destroying the plant from within, making them the ideal solution if you are battling weeds that keep regrowing. However, it'll take several applications before the plants are completely dead.

Contact chemicals only kill the part of the plant where you spray them. This means that they won't reach the roots, which allows the weeds to regrow even after the leaves and stem die.

3. Waterproofing

Since you'll be applying the brush killers to plants situated outdoors, you should know that water can wash the chemicals off the plants rendering the treatment ineffective. That's why one of the things to look for in a brush killer is quick-drying capabilities.

Your chemical could take anything from 30 minutes to four hours to dry. Once dry, the chemical should be rainproof to ensure it'll continue working even when the rain beats against the plant's leaves. The faster the chemical dries, the more effective it'll be against the brush and weeds in your area.

4. Potency

Weed killers vary in chemical potency, which means that they take different periods to completely eradicate the weeds. Some are so effective that you can start seeing results in as little as a day, while others will require you to wait for weeks.

The types of weeds on your property can also affect how quickly the weed killer works. There are plants that you'll have to treat for longer to ensure they won't regrow, while others could quickly die from the first application. If you want fast results, you'll want a solution that is potent enough to work within the first try. Unfortunately, if the chemical is too potent, it can prevent any plants from growing on your land in the future.

5. Safety

The last factor for your consideration is the level of safety the product provides. Unfortunately, the chemical nature of weed killers makes them dangerous for direct contact or ingestion. This means that you'll need to equip yourself with protective gear like gloves and long-sleeved clothing.

You'll also want to avoid storing the chemicals where children or pets can easily access them since there could be severe consequences.
