There are many ways to answer this question. You can look at the calendar, or just wait for the frost to soften up the soil before you plant them out. Beans don’t need very much warmth in order to germinate and grow well, so if there is no danger of frost, then it is a good idea to go ahead and plant your beans now. If you have been waiting for a certain date that has passed by without any frost threat, then it may be better not to bother planting your beans until they have time to harden off from freezing temperatures before going outside into direct sunlight. In this case it would be best not to feed or fertilize them as well – allowing them plenty of space between each other – because once again we want our plants healthy and strong enough so they don’t succumb after their first freeze!
