The first day of spring arrived yesterday, Saturday, March 20th. The day was sunny with temperatures in mid 70s. The daffodils, crocuses, and forsythia blooms are prettier than ever thanks to the snow’s moisture and minerals.
The average date for the last frost for Richmond is April 27th. About 4 weeks before the last frost, which would be around March 27th, is the time to plant dormant roses and bare-root shrubs. Dogwoods and magnolias should only be planted in the spring.
Perennials such as hostas, liriope, Shasta daisies, and daylilies can be divided before new growth starts. Separate the plants and place back into the soil at the original depth. Water well and mulch. Plant the extras in containers for gifts.
Even with the cool days you can plant petunias, snapdragons, marigolds, nasturtiums, and dianthus.
Fertilize lilies, clematis, lilacs and bearded iris with bone meal or 5-10-5 plus lime. Also fertilize pansies and houseplants. Do not begin fertilizing peonies until after they have been planted for 2 to 3 years. A great all around fertilizer is liquid seaweed.
Vegetables that can be planted before the last frost are lettuce, kale, spinach, cabbage, broccoli and Brussels sprouts. Plant onions, potatoes, peas, radishes, asparagus, and turnips near the end of the month. Seedlings started inside will appreciate fertilizing at half strength every two weeks.
Add mulch to asparagus, artichokes, bramble fruits and fruit trees. March is too early to remove mulch from your other plants. The ides of March can bring surprises such as last year when we had an 80 degrees week followed by two frosts.
March is a good time to repot houseplants into larger containers. Leggy plants should be cut back. Root your cuttings for our plant exchange in May. The secret to rooting coleus and wax begonias is to cut the top 6 inches of a leafy stem below a leaf node. Then remove the leaves from the bottom 3 inches and place the cutting in water adding a few drops of bleach. Place in a partially sunny window. Place in soil after roots have developed.
One way to celebrate spring is to attend the free Arbor Day Workshops and Exhibits on April 3rd at Byrd Park.
