We purchased “Sir Walter” about eight months ago, we spread two large truck loads of soil before laying, it looked great at first then some areas starting going backwards, now we have bare patches in our lawn, I have fertilized awhile ago, it is very yellow looking, what should I do?
I have had a look today, and your lawn just needs a bit of extra TLC, the roots of the ‘Sir Walter’ has reached the poor parts of your soil, the lawn will be able to cope with this with help. As I told your wife, I will drop off some gypsum and some maintenance fertilizer for you to apply at the weekend. What needs to be done is to topdress all the weak areas with Mary River sand ( available from Tenkate landscape supplies on caloundra road), but firstly spread gypsum out & the maintenance fertilizer then apply the sand, being careful not to completely smother all the leaves, then water in. Some areas will need another topdressing in september, and fertilizer, this will set your lawn up for summer months.
I know you have been fertilizing in the past but with the amount of recent rain this year and your lawn being only 8-12 old it needs more help, your last block of land had much better soil. I will have the gypsum and fertilizer dropped in before the weekend, at a guess you may need about 1 cubic metre of sand.
