Gardening is not rocket science: If you can dig a hole, turn on a spigot, and snip a dead flower off a vine, you can tend a garden. 

Still, gardeners need  to make judgment calls. How much water does this shrub need? Will that tree get enough sun? Is this hole deep enough? It’s easy to misjudge and make a mess out of the landscaping. Here are common garden blunders.

1. Too many changes too soon. The excitement of warm spring weather often creates a passion for yard work. But what looks like a spring weed might be a fall-blooming vine. Encourage buyers to: Live with their land for a year and observe how many hours of sunlight each part of the garden gets. Test the pH of the soil to determine if acid- or alkaline-loving plants will be happy in that particular patch of heaven.

2. Too much togetherness. Trees and shrubs that look properly spaced when you plant them will crowd each other and compete for water, sun, and nutrients in a few years. Encourage buyers to: Read spacing instructions. Give trees plenty of space—they can always fill in later. Stagger bushes and plants and create two rows, which will create more breathing room. The results will look absurdly sparse at first. But live with it. In a few years, shrubs will fill empty spaces without suffocating each other.

3. Planting without a plan. Planting new garden beds without a long-term landscape plan is like pouring a house foundation without blueprints. Encourage buyers to: Draw a simple sketch of their yard—what’s there now and what they might add later, including patios and pools. Learn about the trees and shrubs that grow best in their soil and climate. A professional landscape designer can create a starter plan for as little as $250 to $500.
