6 OR­GANIC WAYS TO CRUSH YOUR CALI THIS­TLE PROB­LEM

NZ Lifestyle Block - - Feature Country Calendar: Winter - You need to be per­sis­tent to get rid of this per­sis­tent weed. It typ­i­cally takes three years to achieve a sig­nif­i­cant (eg, 90%) re­duc­tion of this­tle biomass us­ing any tech­nique.

1 DEEP RIP­PING/SUBSOILING TO CRUSH THE UN­DER­GROUND RHI­ZOME

This re­quires the use of spe­cial­ist equip­ment but it ba­si­cally crushes the root sys­tem.

2

THE USE OF GOATS

Goats are more par­tial to this­tle than cat­tle and sheep.

3

MOW IN THE RAIN

This has been val­i­dated by Agre­search - mow this­tles off in wet con­di­tions which al­lows for greater trans­fer and in­fec­tion of a range of fun­gal dis­eases into the cut stems.

4 US­ING NOVEL MA­CHINES SUCH AS THE COMBCUT

This is a spe­cial­ist cut­ting sys­tem that is con­sid­er­ably faster than top­pers or mulchers.

5 PAS­TURE AND CROP COM­PE­TI­TION

Re­search shows Cali this­tles strug­gle when un­der heavy com­pe­ti­tion from plants like chicory and lucerne, or mixes of green ma­nure cover crops like trit­i­cale, rye and vetch.

REGULAR MOW­ING

Mow­ing reg­u­larly cuts back the leaves, mean­ing the root sys­tem runs out of the en­ergy it needs to keep grow­ing.
