When is the best time to plant annual flowers outside?
Rate This FAQ
There are cold hardy annuals – they could have been planted out as early as mid-March, so long as they were acclimated and protected from a possible hard freeze.
Half-hardy annuals may be planted out one or two weeks before the average last frost (May 19 at the Salt Lake City airport) but must be protected from frost (cover with a frost cloth on cold, clear nights). Some of these can tolerate light frost if they are acclimated – when recent temperatures have been chilly.
Tender annuals are very susceptible to frost damage and should not be planted out until after all chance of frost is past. Watch the weather forecasts during late May – if a cold front may move in you should wait until it passes.
