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.

- How do I store my summer bulbs?
- I have 4 lovely crenshaw melons on my home garden vines -- 1 large, 2 medium, and 1 small. None of them have gone yellow/white yet! We survived the snow flakes last weekend (I covered everything), but I see we are about to get another "hit" this weekend! Is there ANYthing I can do to speed up their ripening?? I have cut back my watering of the vines, but sprinklers still go on automatically in the morning. Would any of the "usual" things people do to ripen melons indoors (paper bags, put them with a banana, etc.) do any good while they are still on the vine?? From everything I have read, if they are picked while they are still green, they will never ripen -- is this true? If I keep them well covered during our few nights of 32-33 due this weekend, will they survive on the vine to ripen?
