Garbage to Urban Garden

Step 4: Plant and Water Seeds

Now you can fill the little cups with dirt, leaving about 1/2 an inch of space from the top edge. How deep you plant the seeds has to do with what kind of plant you are growing, so make sure to follow the instructions on the seed packet as far as depth and watering go. Try to find a place with access to the sun by a window or outside and continue watering the plant as instructed. Usually, whenever the soil around the plant is dry to the touch it is time to water.
