May 2022 Gardener’s Almanac Checklist

May 2022 Garden Tips and Checklist

  • Plant warm season vegetables and annual flowers once the threat of the last frost has passed. Click here for a listing of the average last and first frost dates.
  • By planting tomatoes deeper, they are able to form more roots along the stem creating a more vigorous plant.
  • Consider planting sweet corn in the garden every other week (until early July) to extend the harvest.
  • Consider the various types of fertilizers. Click here for more information on traditional fertilizer options. Click here for more information on organic fertilizers.
  • Thin out overcrowded seedlings using a pair of scissors, trying to avoid disturbing the young roots.
  • Protect fruit blossoms and tender garden plants from late freezing temperatures. Click here for critical temperatures in fruit.
  • Plant summer blooming bulbs including gladiola, begonia, dahlia and canna.
  • Divide warm season ornamental grasses when new growth begins to emerge.
  • Click here for more information about landscape weeds.
  • Allow the foliage of spring blooming bulbs (tulips, daffodils and crocus) to die down before cutting the leaves off.
  • Click here for information on planting a lawn.
  • Turfgrass needs minimal irrigation each week. Click here for irrigation needs in your area.
  • In compacted sites, aerate with hollow core aerator when turfgrass is actively growing (April – June).
  • Control broadleaf weeds in the lawn when temperatures are between 60-80°F. Follow the label and stop use of broadleaf herbicides once the temperature is above 85°F.
  • Apply a slow-release lawn fertilizer to provide a long lasting affect throughout the summer months.

Pests and Problems:

  • Monitor newly planted vegetables for Cutworm and flea beetle damage.
  • Monitor for Cankerworm damage on scrub oak and Box elder trees along the foothills.
  • Monitor for aphids on lush new spring growth on a variety of plants. Treat for aphids by using “softer” solutions such as spraying them with a hard stream of water or by using an insecticidal soap.
  • Monitor for slugs and snails. These pests thrive in moist, cool areas of the garden and landscape feeding on a variety of plant hosts.
  • Protect Ash trees from the Lilac / ash borer around the first of May.
  • Control Codling moth in apples and pears to reduce wormy fruit. For specific timing see our Utah Pests Advisories.
  • Treat for powdery mildew on apples beginning when leaves are emerging (at 1/2 inch green) until June.
  • Watch for insect pests in raspberries from mid-May thru early June.
  • Watch for Cutworm damage in turfgrass and new vegetable starts.
  • Monitor for damaging turfgrass insects. In areas previously damaged, consider a preventative (systemic) insecticide.
