How to Identify Pokeweed
How do you identify a pokeweed? If you can’t identify the plant, you definitely wouldn’t be able to get rid of it. Various names like Pokeroot, Pigeon Berry, Cancer Root, Inkberry Coakun, American Nightshade, Pokan Bush, etc., are identified as pokeweed.
The plant has a Southeastern United States origin but has expanded into other countries due to its invasive nature; for instance, a pokeweed plant can produce as many as 50,000 seeds. Birds and other animals distribute these seeds.
Pokeweeds have long oval leaves and red woody stem. From July to September, the plant grows greenish flowers and grape-like clusters of berries.
The berries or fruits pokeweed have traditional, medicinal purposes, but they can be toxic to humans and animals in the same vein.
How Poisonous Is Pokeweed?
Pokeweed is very poisonous. Every part of the plant is dangerous and should not be ingested. The toxins found in pokeweed are oxalates and saponins. The part of the plant that is most toxic is the root, and the least toxic is the berries.
Kids are more susceptible to being poisoned by pokeweed, which is because they are attracted to pokeweed berries. A small amount can be fatal in kids.
It is not only kids that are at risk here. Livestock is too. But most livestock smells their food before eating it. Naturally, they know that it is not suitable for them, and they do not taste it.
How to Get Rid of Pokeweed
Though pokeweed is a tough plant to get rid of, there are still methods by which you can remove them.
But before you get right into it, you have to get your protective gear-pants, long sleeves, gloves, and goggles for the eyes. These protective gears will protect you from the toxic sap of the pokeweed.
If you have a pokeweed in your garden, remove it as quickly as possible. Why? Because the larger it grows, the stronger the roots become. This will make it too hard to get rid of.
Some of the tools you may be needing are a soil screen, rototiller, rake, shovel, wheelbarrow, and a garbage bag. Here are the next steps if you have the tools above:
1. Pull Out the Roots
Take hold of the shoot near the plant base and then pull it up. Be careful as you uproot them, so they don’t break and remain in the ground.
Even the smallest of roots let underground can grow into new plants. The best time to try pulling out the root of the pokeweed is just after rainfall. The rain helps to soften the earth and make your work way more comfortable.
2. Removing the Plant
For you to get rid of the plant, dig around the pokeweed plant, 12 inches across. Dig deep and remove the taproot. Dig until you can no longer see any root.
Leaving a root inside the soil will cause the plant to grow back up again. And if this happens, you have to do all these over again.
3. Dispose of the Plant
When you get out of the plant, place it on cellophane so it will dry out. As soon as it dies, set it inside the garbage, and throw it away.
Uprooting it and then dumping it on a garbage pile may result in the plant growing again. Hence it must remain in the cellophane.
4. Recheck for Hidden Roots
Get a rototiller to dig around the soil to check if there are still roots remaining that need to be removed and gotten rid of.
5. Get Rid of Berries and Fruits
Check thoroughly and make sure nothing toxic is still hiding in the soil. There is an emphasis on this because the berries and fruits are poisonous to man and animals.
Check also for another growth in the ground and uproot it. If there is new growth, you will have to redo the process. When you have gotten rid of the pokeweed, plant something beneficial there.
