Although this title seems like a song lyric, for the warmest of the warm season vegetables it's true. Tomatoes, peppers, eggplant, winter squash, pumpkins, watermelon and cantaloupe have more requirements to think about than not being able to take frost.
For what seems to be everybodys' favorite vegetable, tomatoes, it may be tempting to plant outdoors in a year like this when the apparent last frost was April 16. Stunted growth and susceptibility to pests such as flea beetle results. Plants can normally outgrow this pest when they are established quickly and get up and growing but are severely set back when stunted by cold nights and eaten by pests.
Waiting to transplant can often result in better growth and a harvest that arrives just as early as plants transplanted before the arrival of warm nights.
