Rodney Times - - GARDENING -

All this heat and rain has nur­tured a new gen­er­a­tion of weeds the size of small cats in my peren­nial bor­der. For­tu­nately, be­cause the soil is damp, the weeds have been sat­is­fy­ingly easy to pull out. Not so easy to ex­tri­cate is con­volvu­lus which has snuck through from the neigh­bours’ and is do­ing its best stran­gu­la­tion work. I’m go­ing to take a leaf out of col­league Bar­bara Smith’s book and tack black plas­tic around the bot­tom of the fence line to pro­vide a bar­rier.

Mostly weeds are just

plants grow­ing in the wrong place, but if they’re hog­ging space, stran­gling your plants or just un­sightly, dig, hoe or fork them out, roots and all. Adding a 50mm layer of mulch to the soil will help pre­vent new weeds from emerg­ing.

Com­post any weeds with­out seeds. If you have nox­ious weeds, such as trades­cantia, place the weeds in a plas­tic rub­bish bag with a hand­ful of soil and wa­ter, tie up the top and leave them for sev­eral months un­til they’re dead as door­nails.
