Seasonal Suggestions

You can get an early start on vegetable and flower gardening by planting seeds indoors. March is a great time to add color and interest by planting summer-flowering shrubs and vines. Flowering vines are a great way to dress up an entryway or to add color. Try growing these pink-blooming vines: Queen's Wreath (Antigonon leptopus), shown here; pink bower vine (Pandorea jasminoides) or pink trumpet vine (Podranea ricasoliana). Red bird-of-paradise (Caesalpinia pulcherrima), Baja fairy duster (Calliandra californica), Texas sage (Leucophyllum frutescens), chaparral sage (Salvia clevelandii) and Arizona yellow bells (Tecoma stans stans) are large summer-flowering shrubs that add great color to the landscape. Large shrubs, 5 feet and higher, should be planted toward the back of the landscape. Shrubs are a great way to hide a wall, fence and pool equipment from view. Plant lower-growing shrubs and perennials in front of taller shrubs. Prune frost-damaged growth. Make sure to wait to prune until the danger of frost has passed. Not sure when your last frost date is? Check out your city's average frost dates. For most fruit trees (apples, apricots and plums), you will get the best fruit production if you buy at least two different varieties of each type of tree. This is because many fruit trees cannot pollinate themselves; they rely on pollen from the same type of tree but a different variety.

Happy Gardening!

Summer…the hardest season on the garden & the gardener…Re-mulch beds to conserve moisture.

  • ​ Water and feed regularly. It is best to water plants & lawns in the early morning or late evening.
  • ​ Water plants with a thorough soaking rather than frequent light sprinklings.
  • ​ For repeat bloom, shear back annuals & perennials that have finished their bloom.
  • ​ Keep annuals dead-headed & continue pinching mums.
  • ​ Prune climbing roses after first bloom & summer prune all roses to remove 1/3 of each cane that produced spring bloom.
  • ​ Plant caladiums when night temperature is above 65 degrees.
  • ​ Late July & August: plant or divide bearded iris & day lilies.
  • ​ Don’t mow bermuda grass too short.
  • ​ Tan speckles on lower leaves indicates spider mites. Hose plants with a strong jet of water for several days.
  • First frost: November 13 (earliest on record October 6)
  • ​ Fall is for lawns. Cool air & warm soil is ideal to seed bald patches & feed the entire lawn.
  • ​ Plant shrubs, trees, & other perennials.
  • ​ Plant spring flower bulbs (refrigerate tulip & hyacinth bulbs for 6 weeks after purchase… make up for our shorter winter).
  • ​ Late September: divide day lilies & spuria iris.
  • ​ October, November, & early December: plant daffodils, Dutch iris, jonquils, oxalis, & ranunculus.
  • ​ Set out snapdragon, stock, daisy & pansy plants.
  • ​ Plant sweet pea, poppy, & larkspur seeds.
  • ​ Protect all potted plants or bring indoors before night temperature falls below 45 degrees.
  • ​ Improve your planting beds’ soil with compost & mulch over with organic material such as shredded leaves, pecan shells, or composted bark bits.
  • ​ Fall is also for starting seeds for spring veggies like peas, spinach, lettuce, Swiss chard, broccoli, etc.
  • Irrigate deeply all plants every 2-3 weeks to prevent winter damage.
  • ​ January: prune trees & non spring-flowering plants. Plant new roses & new trees/shrubs. Save fireplace ashes as fertilizer for your iris & other alkaline soil plants.
  • ​ February: prune roses (except climbing) & spray fruit trees, roses, and all deciduous plants.
  • ​ Plant summer blooming bulbs (i.e., gladiolas, amaryllis, lycoris, nerine).
  • ​ Separate & transplant most perennials.
  • ​ March: plant/divide summer bulbs & tuberous roots like gladiolas, cannas, & day lilies. Also, perennials like phlox, gallardias, gazanias, carnations, & salvia. Begin pinching mums.

LAST FROST: March 21 (latest on record May 2)

  • ​ Prune Spring-blooming shrubs after they bloom.
  • ​ Check for and combat pests like red spider mites and aphids.
  • ​ Increase watering schedule & plant tender annuals after last frost.
  • ​ Begin routine feeding for all plants.
  • ​ Plant a summer vegetable garden.
  • ​ Plant dahlias in May.
