How to Manage Pests

Pests in Gardens and Landscapes

What to look for in a plant:

  • Plants well adapted to your environmental conditions
  • A plant that when full grown will fit into the space provided
  • Pest-resistant species
  • Roots and crown free of rot, galls, wounds
  • Roots not kinked or circling the main roots
  • Roots that aren't compacted or too small
  • Good overall plant appearance
  • A tree trunk that has not been headed back or topped
  • A trunk without wounds that can stand without being staked

Choosing plants

Choose plants that will be well suited to local conditions.  Determine the physical properties of the soil where you plan to plant.  Learn which plants tolerate local soil conditions and choose from among those species and varieties.  If necessary, aerate and amend the soil and provide adequate drainage.

Landscape plant species vary in their climatic adaptation.  Choose plants that thrive within the water limitations and overall climate in your area.  Choose plants that can tolerate the coldest and hottest conditions expected in your area.  Too much or too little sunlight causes the foliage of susceptible species to discolor, die, and drop.  Excess heat, or light that converts to heat when it contacts surfaces, causes cracked and sunken bark, which can promote wood-boring insects, bark cankers, and decay fungi. 

Choose good-quality stock and avoid planting species or varieties known to be prone to serious problems in your area.  Group together plants having compatible growth characteristics and similar needs for irrigation and other cultural care.
