Garden centers sell plants. They rarely sell the thing that makes those plants take.

If you have ever put good compost on a bed and watched it sit there like cake frosting, that is compacted soil. Water runs off. Roots stall. You blame the seed packet.

You do not need a tractor. You need one shallow pass, then a second a little deeper, when the soil is damp not wet. That is the whole job. Do it once at the start of the season and most backyard plots jump a full month ahead.

I built Growrig for that job. Compact, ships to your door, meant for people who shop the garden center on a Saturday and still want a real harvest.
