fertilizing the pansies - Your pansies are probably still blooming and will benefit from a biweekly application of liquid fertilizer. And, if you have the time, deadhead the faded blossoms as well.
pruning - Mid-late February is usually the best time to prune hybrid tea roses and summer flowering shrubs such as crape myrtle, chaste tree, rose of sharon, hibiscus, etc. Trees and evergreens can also be pruned now.
start keeping records - If you don't already do so, start a gardening journal or blog to keep a record of your garden. Keep track of when plants were planted, things that were successful and those that were not. Record where you purchased plants and tools. Make notes about the weather. Take photos of everything. In years to come, you will look at your older photos and be amazed at how things have changed!
