How to Identify Common Garden Weeds


Groundsel grows up to 5cm – 22cm high, it’s leaves are lobed and its flowers are yellow. Its seeds set within 4 – 6 weeks, meaning they grow fast and may cover a wider area due to the wind. They germinate all throughout the year except during mid-winter. 

They commonly grow on dry soil or along with the plants that grow under shade. Make sure to check plants you grow under shade, and remove any flower heads after hoeing the ground to get rid of them.


ChickweedChickweeds are about 5cm to 7cm high, they have small white flowers and have extensive root system, making their growth vigorous. Its seeds germinate well in damp soil during Spring and Autumn, or a wet year’s Summer. 

Any seedlings you can spot that are chickweeds should be hoed in dry weather or pulled by hand if the soil is damp. They can survive mild winters, so make sure to act fast before they set seed in Spring.


Charlock grows up to 60cm high, they have yellow flowers, and are often seen in large patches. Its seeds germinate in all seasons, more commonly in Spring. It’s part of the brassica family, meaning they can harbor pests and disease.

Fat Hen

Fat Hen are about 27cm high garden weeds, they have broad leaves and small green or white flowers. In neolithic times, they were eaten as a vegetable due to their richness in vitamin C. 

They may seem harmless, however, they may take over your vegetable garden because they commonly grow on rich soil.

Common Fumitory

They have delicate and attractive flowers, and despite the fact that their seeds remain viable for a long time, they’re not considered as an invasive weed.

Hairy Bittercress

Hairy Bittercress grows 3cm – 5cm high and grows with tiny white flowers. Its seeds set in 4 – 6 weeks and may spread around 3ft away. They love growing in cool moist conditions, so it’s best to improve drainage. The weed commonly grows on the surface of compost in nursery plants.

The Prickly Milk (Sow) thistle grows up to 90cm high, however, they are often smaller and grow pale yellow flowers. The seeds set best in a dry and shaded position, it takes 4 weeks for it to set. Therefore, they should be spotted and removed as early as you can. They have a strong tap root, and will make it difficult for you to remove.  They grow any time they want, even in winter.  


Oxalis grows about 5cm high. Its seeds are dropped from barely visible pods. They often invade nursery plant pots, so make sure to keep an eye out for it because they multiply fast.

I personally started gardening around 6 years ago and initially, I started out by growing my favorite fruits and berries, such as strawberries, Raspberries & Gooseberries. Since then I’ve added a lot of vegetables and working closely with my neighbor, it’s been a lot of fun.
