How to help annual plants to go through the winter (Part 2)
Rosemary
Water the plant the day before you plan to transplant it. This flower need good drainage and does not like to have its roots sit in water. You can avoid standing water by adding small rocks or haydite to the bottom of the container you are going to be using, then add potting soil that has been previously mixed with vermiculite. Put the plant to the container and water it well. Make certain that the superfluous water drains out. Place the plant in a sunny area and water once a week.
Bougainvillea
Bring in your hanging basket from the garden, but first check it for any signs of insects in the soil and on the leaves. Prune the plant back in the autumn and put in a cool place during the winter. The plant will now enter a dormant period where it should be kept dry. In March, move the plant to a warm place and start watering. This flower is hard to get to re-bloom, but it worth the effort.
There are some other plants that can be easily brought to spend the winter inside: coleus, geraniums, basil and begonias.
