Gravel: budget friendly good drainage; low-maintenance; won’t disrupt plants’ roots; can stand up to fairly heavy traffic. Cons Inorganic, so it doesn’t improve soil; without the right border, gravel pieces can spill out into garden areas. May need to be weeded occasionally. Tip Use small, angular stones instead of rounded pebbles. They lock together for a more stable walking surface.
