Im completely new to this we moved into new house recently and let back garden get overrun with weeds…they were about 2 foot high..i have strimmed the whole thing and then rotavated it twice…what do i do next should i spray with weedkiller…a friend of mine told me i should lay grass seed and then lay weed and feed?? To kill the weeds and feed the grass??
Then mark out beds and lawn area.
in the lawn area, let the soil settle or trample it firm to avoid uneven subsidence later. Then sow grass seed and plant up the borders.
