Whats the best to repair dry spots and grow grass in shaded areas
top soil, sod& fertilizer , very inexpensive, don't forget water
What I did. I take fertilizer and add to soil only where it's dead not putting any on the grass growing. Water in well and the growing grass will creep over to the bare spot. This works well even with a very shaded area Works for me.
sprinkle some grass seed on it.
You probably need grass seeds that do well in shade, there are different types. Talk to someone at your local nursery, or plant some shade plants there instead (hostas do well in shade).
I have lived in two houses where there were shady spots. In the first house, the spot was along the back wall, right outside the back door. My incredibly handy dad designed a redwood desk to fill up the space, and I got tons of enjoyment from it. Looking at your photos, there seems to be one spot next to your patio. I would just take flat concrete paving bricks and fill in the spot even with the patio. Or hire a contractor to extend your patio to the end of your house. You can put large potted plants around for "landscaping" there. My present house has gigantic oak trees in front, grass won't grow well under their limbs, so I just planted lots and lots of English ivy -- which loves shade. I started my ivy "patch" 9 years ago, by taking small cuttings and small rooted plants from nurseries and putting them in the soil Now, it has grown into an incredibly thick solid planting that covers about half of my front yard on one side. It needs next to zero care (Just occasional weeding, and some watering during droughts) and looks great. Bonus: ivy does not have to be mowed! That's why I've decided to expand the perimeters of the ivy patch so it'll go all the way to the public sidewalk.
