🌿 Clive’s Tips for Getting Rid of Purple Weeds
These purple - blossom weed might be pretty , but they can quickly take over if left to their own devices . Here ’s how I tackle them in my own garden :
1.Pull Them Early (and Often)
The earlier you remove weeds , the easier your problem will be . Get them before they flower and overspread seed . Do n’t just grab the elevation — strain to remove as much of the root system as potential to check them from bouncing back .
2.Use a Weeding Tool
For anything with deep or spreading roots — like Creeping Thistle or Ground Ivy — a right weeding tool or fork makes a world of difference . It helps you lift the whole works without breaking the rootage and leave behind bits behind .
3.Smother Them With Mulch
If purple weeds keep pop up in the same daub , smother the field with a thick bed of mulch . I wish barque chips , compost , or even cardboard with soil on top . This block light and stops germ from sprout .
4.Improve Your Lawn Health
A dull , sound lawn leaves no room for weeds to sneak in . I feed my lawn in spring and declination , cut down on a regular basis ( but not too curt ) , and manage marginal patches . Weeds hate competition .
5.Don’t Let Them Go to Seed
Many weed — like Dove ’s Foot Cranesbill or Viper ’s Bugloss — diffuse like wildfire once they set about seeding . Deadhead or remove flower heads before they have a chance to set come and scatter .
6.Consider Natural Weedkillers
simmering water works wonders on driveway weeds . Vinegar solutions can scorch parting but wo n’t normally kill the beginning , so they ’re well used alongside other methods . I lay aside chemical substance weedkillers as a last resort — and always spot - delicacy carefully .
7.Be Patient and Persistent
