About Groundsel

Common groundsel is a winter annual weed in the Asteraceae (daisy) family. It's native to Europe, North Africa and temperate Asia and came to North America mixed with grain brought by settlers. Common groundsel can be controlled by pre-emergence broadleaf herbicides labeled for use. Tilling the soil in the fall and early spring and covering the area with a thick layer of coarse mulch will prevent the plant from growing.

How to fertilize Groundsel

Nutrient, fertilizer, and repotting needs for Groundsel: repot after 2X growth

Most potting soils come with ample nutrients which plants use to produce new growth.

By the time your plant has depleted the nutrients in its soil it’s likely grown enough to need a larger pot anyway.

To replenish this plant's nutrients, repot your Groundsel after it doubles in size or once a year—whichever comes first.

Groundsel is extremely dangerous if consumed. If you, a family member, or a pet has ingested any amount of plant material contact Poison Control, US (800) 222-1222, or your veterinarian immediately. Groundsel is not recommended for homes with children, cats, or dogs.


💨 Humidity

Groundsel prefers dry environments. Providing extra humidity or misting your plant allows water to linger on leaves, which can create the perfect environment for harmful types of fungi.

🪴 Soil

Groundsel is very sensitive to wet soil, so choose a potting soil that drains very well and doesn’t retain too much moisture. A good soil will have lots of perlite or vermiculite for drainage and some organic matter for nutrition. A few handfuls of perlite added to regular store-bought cactus soil will do the trick!

🍂 Yellow Leaves

Yellow leaves aren’t always a reason to panic, and can be a normal part of a plant’s life cycle. Unless brand new leaves are turning yellow or all the leaves change color at once, it’s likely just your plant shedding old leaves.

Overwatering and root rot are the most likely cause of problems in Groundsel, since they are very sensitive to wet soil. The leaves may also appear to be curling or drooping. Less often, yellow leaves are caused by underwatering, nutrient deficiencies, or pests.

Replace soggy soil with fresh, dry soil and download Greg to make sure your plant never gets overwatered again!


🧐 Troubleshooting

When troubleshooting a sad-looking houseplant, start by checking for signs of distress in its leaves, such as yellowing, browning, or drooping, which can indicate overwatering or nutrient deficiencies.

Inspect the soil moisture; too dry or too wet soil can cause problems.

Ensure the plant is getting the right amount of light, as too much or too little can stress it.

Finally, consider environmental factors like temperature and humidity, and adjust care routines accordingly to revive your plant.
