Creeping thistle

Time to act:

Jun, Jul, Aug, Sep, Oct, Nov

Creeping thistle, Cirsium arvense, is a pernicious weed that will quickly take over your garden unless kept in check. Winter is the only time of year that offers a reprieve, but for the rest of the year the best way to tackle it is to dig it out as soon as it appears. It's armed with extremely sharp stems from tip to ground, so don't tackle it without a sturdy pair of gloves.

Symptoms

Creeping thistle is a rampant weed that's spread via wind-blown seeds, as well as roots that can grow 6-12m per year. If left unchecked, it can rapidly dominate areas of your garden.

Organic

The best way to deal with thistles is to get a fork under the plant and gently tease out as many of its spreading white roots as possible. Although a new plant will generate from any pieces of root left behind, these will become weaker and easier to remove each time you dig them out.

Chemical

Use a total weedkiller, such as glyphosate, on this weed, as it'll kill the plant without leaving a residue in the soil. Avoid spraying on a windy day and near other desirable plants.
