FYI, When to plant flowers :)
When should you plant flowers? The short answer is this:
š±Start seeds indoors weeks before your last frost date
š»Transplant hardy flowers before or at last frost
šøPlant tender annuals after frost danger passes
š·Plant spring bulbs in fall, summer bulbs in spring
However. . .
Different plants need differing amounts of lead time before they are ready to be transplanted into the garden. Starting too soon can result in a weak, lanky plant, while starting too late can give you one that is just not ready for the outside worldāboth will struggle to survive!
