Yes, the choice is really huge, especially if you want to get a quality lawn. I usually buy everything through the marketplace - there are verified sellers, and you can compare different types of seeds according to conditions: sun, shade, soil type, etc. It is also convenient that you can immediately choose fertilizers and care tools. I advise you to choose the grass that suits your climate and lighting. If the plot is sunny, take a heat-resistant one. And for shady places there are special mixtures with softer varieties.
