“Spring is nature’s way of saying, ‘let’s party!’” – Robin Williams
1. As the weather warms, you can put seedlings outside during the day to harden them for their eventual relocation into the garden. Don’t leave them out overnight at this time.
2. There can still be a late frost, but normally you can start planting most vegetables into the ground (except for cold-sensitive plants such as tomatoes and peppers).
3. This is the time to plant potatoes. There is an old saying: Potatoes planted on Saint Patrick’s Day will mature by the Fourth of July – just in time for potato salad.
4. There is still time to get in a crop from cool-season seedlings of cabbage, cauliflower, celery and green onions. From seed, plant arugula, escarole, frisee lettuce, radishes and lettuce. Also set out artichoke plants and asparagus roots now.
5. Now is the time to plant summer bulbs such as amaryllis, callas, gladiolus, lilies and tuberous begonias.
6. If you haven’t started feeding your roses, start feeding them now with your favorite rose food once a month. For more information, visit http://ipm.ucanr.edu/PMG/PESTNOTES/pn7465.html.
7. Fertilize citrus and all flowering plants that are about to bloom. Trees, shrubs and cool-season lawns could use a high-nitrogen fertilizer.
8. Fertilize azaleas, camellias and rhododendrons when they finish blooming.
9. Start cleaning up old blooms from your spring-blooming bulbs. Removing seed pods from daffodils will increase their energy for next year’s blooming cycle.
10. Prune spring-blooming plants as they finish blooming. Toward the end of the month (but before new growth begins), prune back both oleanders and crape myrtles to produce new flowering wood.
11. Remove only damaged branches when planting new trees or shrubs, and leave the plant to settle in for at least one year before you begin any formative pruning. Plants need all the branches and leaves they have when they are trying to get established. For more information, visit http://homeorchard.ucanr.edu/The_Big_Picture/Pruning_&amp;_Training/.
