Weed and Fertilise
September 1, 2021
So Spring has finally arrived, so if you’re sick of being in lockdown and looking for some fun activities outside it’s the perfect time to start working on that lawn.
It’s time to address those weeds and fertilise!
When your soil gets below a certain temperature, usually about 14 degrees, your lawn goes into dormancy and the growing stops or slows down considerably. Most weeds however, have adapted and enjoy the cooler soil conditions so they continue to sprout and grow. Weeds are also much more obvious over the cooler months as you are not having to regularly mow your lawn so they get the chance to stand out from the crowd. Because of these reasons, it is critical to fertilise after your weeds have been treated, and while your lawn is growing. You want the grass to be absorbing the nutrients and not the weeds!
The best way to address those weeds is to first remove them by hand and then apply a selective herbicide to attack any particular problem weed.
The best time to treat your lawn for weeds is towards the end of winter or now at the start of spring, as your lawn is less likely to be affected by the herbicides as it is still dormant and the weeds are more susceptible as they are still growing.
After the weeds have been treated, it is time to fertilise your lawn. To get the most out of the fertiliser, it is best to wait until your lawn is growing again before applying. Waiting until after your first or second spring mow is a good way to ensure your lawn is out of dormancy and growing again. This is the time your lawn is ready for a feed! A high nitrogen NPK fertiliser is recommended, and always be sure to irrigate after application. To keep a healthy looking lawn year round, it is recommended you apply fertiliser every 8-10 weeks from October to April.
