Pineappleweed occurs in cereals and broad-leaved arable crops and has become a frequent weed of intensive vegetable crops. It is also a common garden weed.

In sandy loam soil, seedlings emerge from the top 0-10 mm of soil with the majority emerging from the surface 5 mm.

Based on seed characters, pineappleweed seed should persist for longer than 5 years in soil. Seed mixed with soil and left undisturbed declined by 83% after 6 years but in cultivated soil the decline was 91%. Seed buried in sub-arctic conditions had 20% viability after 6.7 years.

An introduced annual weed of wasteland and bare places by paths. Pineappleweed was introduced into the UK just prior to 1900 and within 25 years it had spread along roadsides throughout most of England. Pineappleweed is now common throughout the UK, and is still increasing, especially on tracks and paths and on cultivated land. It prefers an open loamy or sandy loam soil.

Seedlings and larger plants should be controlled by cultivation and hand weeding to prevent seeding. Pineappleweed seedlings are more numerous on tine-cultivated or no-till land than ploughed land.
