Sow Thistle & Hemp Cultivation

 Pest plant (weed) alert! 

Sow Thistle, Sonchus sp., an invasive weed in the hemp cultivation area

Sow thistle, Sonchus sp., is native to Eurasia and Africa but can be found across Florida in yards, farms and in the woods. 

Each plant can produce up to 10,000 seeds and each seed can last many years, laying dormant until the right conditions come along. The young leaves can also be cooked as potherb greens. 

The problem with sow thistle is that the plant is so prolific and hardy with it's fat tap root that sow thistle takes away habitat from native flora (botanical adverse possession) and can crowd out hemp plants in the cultivation area.

I just mow or weed eat sow thistle down before flowers form, preventing the plants from reproducing, keeping them out of the garden. 

Often mistaken for dandelion, sow thistle is in the aster family. Both have basal rosettes yet the leaves are considerably different. Aphids are often attracted to sow thistle.
