I asked staff members what they would do to make their landscapes beneficial on a limited budget. Here’s what they said:
Budget Kendall Bob Christina JustinDead Broke
I’d start a compost pile. You can build a bin with basic home-owner tools &salvaged materials.
I’d build up the soil and make landscape beds. It’s sweaty, but mostly free. I would gather leaves from my own yard and others nearby and ask around for old manure and straw that I could add.
I’d look at simple maintenance changes like managing my grass differently and redirecting my downspouts. I’d also mooch off my neighbors for plant material!
It’s not what you do but what you don’t do. Relax on mow-ing, let mother nature take its course. If I could get free mulch, I’d mulch around my trees and shrubs. Beg plants from other people. Plant an acorn! I have eight shade trees in my yard I started from acorns.
$100 Plant a vegetable garden! The supplies to create one are cheap, it will feed my family and I can put the compost to use!
I would spend some money on tree seedlings (they will grow!) and a few small container shrubs that would eventually grow to larger specimens.
I would add compost to existing landscape beds and purchase some high-impact shrubs (those with great habitat value).
Buy a shovel and wheel-barrow to build soil &move plants.
$500 Buy a reel lawn mower, which runs from $100-$500. I would also buy a few fruit trees.
Install a perennial garden. I would also add some more shrubs to my landscape.
I would spend some money on a small grow-bag shade tree. I would also buy more shrubs and perhaps a small-growing native tree, like serviceberry or pawpaw.
Holy cow, we could really change the landscape! For under $500, I built a shade frame, compost bin and work-ing area where I’ve started tons of new plants.
$1,000 I would tear out the existing privet, Alberta spruce and hy-drangea shrubs in my front yard and replace them with more beneficial plant material.
I’d buy bigger-sized plants!
I would install a rain garden! It’s a great way to capture rainwater, they’re beautiful and insects love the native grasses and peren-nials used in them. Most large municipalities have cost-share programs for homeowners (free money!)
I’d do all of the above and re-place a third of my lawn with beneficial plants for insects and birds. With the $500 left over, I’d go to the Smoky Mountains and hug some of the ancient trees there.
