Dandelions are a nuisance growing in, and if we are not careful, taking over our lawns. In this article, I'm going to explain two main ways of getting rid of them. The Organic or weedkiller methods to clear and control dandelions growing in a lawn.
I was going to say eradicate them, but because they spread easily by seed and grow back if even the tiniest bit of taproot is left in the ground, eradication is almost impossible.
On poor acidic soil you could leave them to grow and "slowly" help improve the soil.
Dandelions love acidic, low nutrient soil. They will continue to grow in this type of soil, slowly helping improve it until it is no longer acidic and is full of nutrients and then, job done they will be crowded out by healthy lawn grass. This Organic method of clearing dandelions from your lawn, could depending on the size of the area, take a long time, but can be sped up by addressing the pH and shortage of nutrients by adding material from your organic compost heap.
An important step if you use this organic method is to behead all dandelion flowers before they go to seed to minimise the volume of seeds. This will speed-up the process, but it is still going to be a slow way of getting rid of dandelions and does take a lot of work initially, but once under control, the removal of the odd dandelion isn't a major time issue and there is a certain amount of satisfaction to be gained from knowing you have done it mother nature's way
Even after you have cleared your lawn, you will get seeds from neighbours lawns who don't bother to keep them under control and the important thing is to keep on top of it.
Another method of removing Dandelions from lawns without damaging the grass or using herbicides, is to dig out the whole plant and root.
Dandelions root deep into the ground making it almost impossible to pull the weed and root out by hand without leaving part of the root in the soil. It's very important to remove the green and root, as even the tiniest bit will grow back into a full size dandelion plant.
These tools make digging out dandelion roots easy the first one is a great invention for removing dandelions, from lawns.
The second one is a specially shaped trowel to get in deep to remove the root.
When I'm clearing dandelions and other broad leafed weeds from lawns, even small areas, I avoid using the expensive glyphosate based weed-killers like roundup and instead dilute the concentrated (360g/l glyphosate available here.
Always check Strength actually is 360g/l when buying concentrated Glyphosate weed-killer from other sources.
Whichever method you use to clear dandelions from a lawn, good maintenance will be essential to keep it dandelion free.
Since dandelions thrive on thin weak turf, a good preventative measure will include the following;
