One of the most frustrating things about starting seeds is waiting for them to emerge from the soil. Pre sprouting seeds germinates seeds before planting. This saves time, eliminates thinning, and conserves space.
Instead of scattering seeds then thinning later, creating seed mats allows you to space out the seeds according to the suggested spacing on the back of the seed package or Square Foot Garden spacing recommendations. Seed mats or seed tapes are helpful for planting tiny seeds, such as lettuce and carrots that are hard to sow one at a time. Also a great project for a rainy day when you can’t get out to the garden.
