Care notes

• Start heat-loving crops indoors in March and transplant after the last frost.
• Water deeply and consistently — irregular watering causes blossom end rot in tomatoes.
• Mulch heavily to keep roots cool and save water in the summer heat.
• Stake or cage tomatoes and peppers early, before they get tall.
• Harvest often to keep plants producing through the season.
