Pest & disease watch
- Overwintering aphids may begin waking up in sheltered areas like under mulch or near south-facing walls as temperatures fluctuate.
- Late-season slugs and snails are often active during brief warm spells before the ground fully thaws.
- Birds will be aggressively feeding on any late-fruiting weeds or stored birdseed left out this week.
Watering this week

Clean up dead leaves from last season now to reduce overwintering disease spores.
Fargo gardening questions
3Can I plant tomatoes or peppers outside right now in Fargo?
No, you must wait until after May 12 when the risk of frost passes and soil warms up sufficiently for warm-weather crops.
What should I do about my garden soil until spring planting season arrives?
Start cool-season vegetables like lettuce or kale indoors now in late winter to give them a head start, but keep lights on 14-16 hours daily.
Should I cover my vegetable beds with plastic now to warm the ground?
It is too early for black plastic mulch; instead, use row covers later in May once seedlings emerge to protect against the late frost date.
