When it comes to Oregon gardening, determining what to plant in April depends on your region. Spring has arrived in the milder climates of Portland, the Willamette Valley, and Coastal regions, but gardeners in eastern and central Oregon are still facing frosty nights that may last until the end of April, or even later where elevations are higher.
The following seasonal garden calendar should provide basic guidelines but always be aware of your particular growing zone before planting. Your local garden center or OSU Extension Office can provide specifics.

Oregon Gardening Tips for April
Gardeners in most areas can prepare garden soil by digging in compost, manure, or other organic materials. However, don’t work the soil if it’s wet, as you may do long term damage to soil quality. April is a good time to fertilize berries including blueberries, gooseberries, and currants.
Gardeners in mild, rainy western Oregon should be working on slug control in April. Clean up leaves, wood, and other debris that serve as handy hiding places for slugs. Set out bait (use non-toxic slug bait if you have kids or pets).
Pull weeds while they’re still young and easy to manage. Be ready to protect newly planted vegetables with row covers or hot caps if frosty nights are predicted.
