May

  • It’s time for some color….plant your annuals & tropicals now!
  • Plant your container gardens now, just remember to water more frequently (especially in warm, dry weather) since roots are above ground & can dry out quicker than if planted in beds.
  • Start fertilizing annuals every 10 days to 2 weeks, especially heavy bloomers.
  • Should be able to transplant any annuals started indoors, just pay attention to cold nighttime temperatures.
  • Prune spring shrubs that have finished blooming.
  • As spring bulbs die out, fertilize once more with bone meal & let green foliage die back naturally, as it supplies nutrients back to the bulb.
  • Can still apply weed control to lawns while days are still cooler. Do not apply once warm weather stays.
  • Start Rose maintenance routine of spraying, watering, feeding & deadheading.
  • Dig & divide early spring perennials, only if they have finished flowering.
  • Can start ‘pinching back’ Chrysanthemum blooms now (through the first of July) to encourage fall blooms.
  • Continue to monitor plant material for insects & disease damage. Treat as needed, following label instructions.
  • Continue to water plant material, especially newly installed landscapes (if no significant rainfall).
  • Plant summer blooming bulbs.
  • Replenish or replace mulch around trees, shrubs & in bed areas to a depth of 3” to 4”. This helps the soil retain moisture during dry weather.
  • Okay to put out tropical water plants this month.
  • Train & trim espaliers & topiaries. Check ties that may be strangling branches & loosen.
  • Continue to edge bed & turf areas.
  • Continue to spot spray lawn for weeds with appropriate herbicide. Follow label instructions.
  • Set stakes for tall perennials.
  • Continue to provide food & water for the birds.
  • Hummingbirds should be back now. Keep them happy with a simple sugar solution (1 part dissolved sugar to 4 parts water). Change the solution frequently if the hummingbirds aren’t draining the feeder, especially if it’s in direct sun. The solution can spoil & become toxic to these amazing little creatures.
  • Can sow warm season vegetables & herbs.
  • When applying fertilizer to trees & shrubs, be careful to place around the perimeter of plant, not near the base or trunk.
  • Now that the landscape has flushed out, this is a great time to consider any areas in your landscape that aren’t performing like they should or trouble spots.
