This week’s heavy rains in Tucson created the perfect storm for winter weeds. For homeowners associations, these early showers are both a blessing and a challenge. While the rainfall nourishes trees, shrubs, and turf, it also awakens dormant weed seeds lying in wait. Wild mustard  and stinknet are among the most common culprits, and if left unchecked, they can spread quickly across common areas, walkways, and landscaped beds.
