| >...is there a way I can ensure that they will survive and bloom next Spring? Your best chance is to plant them right now. And the odds are very good that they will take well. For these, the fall planting is best, and will then produce flowers in the spring. But your concern is to keep them living and get them growing in your garden over time. Plant them now, and if necessary do some watering to keep the soil moist but not wet over the next few weeks. If they sprout out and put up foliage, you are doing fine. They probably won't flower, but that doesn't matter. I go back and forth as to whether to plant them together or split them. Since this particular set matters to you, I would probably leave two together and then split off the other two into individuals. Plant them in different areas. Increases your chances of having at least some of them thrive. |
