I would love for Busch Gardens to come out and landscape my yard- who wouldn't. Like you, I would prefer the prize to go to someone who wouldn't normally have the money or ability to do it themselves.
However, that is not how our world works. To quote Princess Bride: "Life is pain, Highness. Anyone who says differently is selling something."
I am sure the family who is in second is a good family and applied because they really wanted the yard to be beautiful. If you watch any of those House Crasher shows... no one is in any real money problems... they just don't have the time or knowledge on how to do it.
Landscaping seems easy enough- but you have to know soil- what plants handle what light- soil- drought-how big they get- etc. Then there is color composition and so forth. We built a retaining wall in our back yard. One block was about $2.00 at home depot. We are doing OK financially, but build three tiers of a 15 foot long wall at 2 ft high with stone bricks.. yeah it adds up.
We saved money by hauling it all- digging the ground by hand and placing the stonework ourselves... but man- since we couldn't afford the labor- it would have been nice.
Plants are expensive too. One red Japanese maple could run you $120 or more (a small one) Most small potted perennials can run from 4.99 to 14.99 per plant. Say you need 5 small boxwoods at 9.99 each, potting soil, mulch, and then some flowers to make a second row- that would be about 10 of them at 4.99 each...
Hope that puts your mind at ease PR- home ownership is extremely hard work. Unless they have the money to hire an architect, landscaper, gardener, maid, etc... well - the make over seems fine to whoever wins it.
