Tricky here Plant seeds or young plants

Why these dates

Burns's typical last spring frost is June 11. Frost kills melons, so planting starts once frost risk drops, around June 11. Keep row cover or a frost blanket handy for the first couple of weeks, since a late frost is still possible. The season is a little tight here, so an early variety is the safer choice.

High desert and mountains. Central and high eastern Oregon. Frost is possible almost any month. Use row covers, wall-o-water or cloches for warm crops, and choose short-season varieties.

Step by step

  1. Start seeds indoors May 14–21 in trays or small pots under a grow light or in your sunniest window. Or skip this step and buy young plants (starts) at a garden center.
  2. Harden off the young plants: about a week before planting, set them outside for a few hours a day, a little longer each day.
  3. Plant them in the garden Jun 11 – Jul 2, 24 to 36 inches apart. If you plant seeds instead, sow them 1 inch deep.
  4. Water deeply once or twice a week rather than a little every day, and mulch once the soil is warm.
  5. Harvest: Cantaloupes are ripe when the stem slips off with a gentle push. Watermelons are ready when the curly tendril nearest the fruit turns brown and dry.

Varieties that do well here

  • Sugar Baby (watermelon)
  • Minnesota Midget (cantaloupe)
  • Halona (cantaloupe)

Watch out for

Cool soil and cool nights are the main obstacle west of the Cascades. Black plastic mulch and row cover until flowering make the difference.

The toughest heat lover for west-side gardens: choose short-season varieties and use black plastic and row cover. Eastern valleys grow them easily.
