What grass is better to sow on a lawn instead of timothy?

Actually, weeds and lawn grass aren't really the same thing, and you can't just swap one for the other. If weeds show up on your lawn (usually it's chickweed, clover, or plantain), it means there's either too much moisture, poor soil nutrition, or the lawn's been trampled. Just throwing new grass seed on top of this mess is pointless - it won't take.

First, figure out what's causing it. If the lawn is wet and sticky, you need a drainage system or at least aeration. If the soil's depleted, add fertilizer. If it's clogged with debris and moss, do some scarification - rake the lawn with special rakes. Then you can reseed. For lawns, you want grass mixes with perennial ryegrass, red fescue, and timothy - they depend on your specific climate and how much sun your plot gets.

After seeding, keep the lawn moist (but not wet) for a month or two, mow the young grass regularly, and honestly it's better not to walk on it for the first month at all. And next season, keep an eye on how it's doing: mow at 5-7 centimeters, fertilize in spring and fall, fill in any bare spots. A lawn isn't something you seed once and forget about - it's constant maintenance.
