Stop Overplanting: How to Give Shrubs Room to Shine

We've all seen it: flowering shrubs crammed so tight they're sheared into green meatballs. Overplanting strips natural beauty, increases maintenance, wastes water, and shortens plant lives. The fix is simple — read the label before you buy.

Why It Happens

• No research: Buyers see a small nursery pot, ignore the mature-size label.
• Instant gratification: Properly spaced new plantings look sparse; pros and homeowners add extra plants for "full" look.

The Damage

• Natural form/flowers lost to constant shearing.
• Wasted money on extra plants + maintenance.
• Water wasted on unneeded plants; more green waste to landfill.
• Plant stress: competition for water/nutrients; excessive pruning creates dead zones, shortens lifespan.

Spot an Overplanted Area

18 Texas rangers (6+ ft each) in a space that fits 6. Not obvious at planting — do the math.

Fix an Existing Mess

• Research mature sizes; remove excess (often every other plant).
• Or let them grow together as an informal hedge — less pruning.

Prevent It: Simple Math

5-ft-wide shrub = ~25 sq ft. 10×20 ft bed = 200 sq ft → max 8 shrubs. Space row shrubs at least their width apart (center-to-center).
