"Spring makes its own statement, so loud and clear that the gardener seems to be only one of his instruments, not the composer." Geoffrey Charlesworth

March in the low desert Arizona garden is one of the most beautiful times of year. Take time to enjoy your garden this month. Many gardens offer tours during the month of March. Enjoy the beautiful weather at the tour and take note of plants, flowers, trees and vegetables you see growing and would like to add to your landscape. 

There are important garden tasks to do in March, such as pruning frost-damaged plants and thinning fruit trees (see a list of garden tasks for March below). Harvests from fall plantings are ending as planting continues for the spring and summer gardens

Because of the heat of Arizona summers, we have a short growing season. Look for tomatoes with a short (60-90) days to maturity. These are often types with small to medium fruit or Roma or paste varieties. Varieties highly recommended for Arizona include Punta BandaCelebrityPearson and Cherokee Purple.

Pepper plants require a long warm growing season. In the low desert of Arizona, start seeds indoors in late December or early January. Begin hardening off transplants about 10 days before planting in late February and early March.

Growing Cucumbers in Arizona

Cucumbers grow best with a long warm (but not hot) growing season. To overcome the challenges of growing cucumbers in Arizona, the key is to plant cucumbers early in the season and plant short-season varieties that will ripen before the hottest days of summer.

Asparagus harvests begin in late February and continue throughout the month of March. Harvest stalks that are at least ¼ inch in diameter. Let smaller stalks grow through the summer to give energy to the roots.

If you aren’t growing asparagus, consider dedicating a 4 foot by 4 foot raised bed for growing it. Plant asparagus November through February in the low desert of Arizona.

Plant fruit trees this month. Look for trees that have low chill hours (less than 400), mature early, and self-pollinate. This publication from the University of Arizona Extension Office has a list of deciduous fruit and nut trees that do well in the low desert of Arizona.

As blossoms become fruit on your fruit trees, fruit should be thinned before it is an inch in diameter. Thin fruit within about a month after full bloom. Fruit thinned later than this lessens the chance that fruit size will increase. For more information, read this article.

Herbs in the low desert Arizona garden in March

Harvest chamomile when the petals are flat or beginning to fall back from bud. Harvest flowers on a sunny day after dew has dried. Flowers can be air-dried or dried in a dehydrator – they are dry when flower crumbles easily. Use 1 teaspoon of dried petals in diffuser per cup of water for tea. If using fresh flowers for tea, double amounts – drying flowers concentrates the flavor and oils.

Consider planting borage next to each tomato plant. The bees and your tomatoes will thank you.

Low desert Arizona garden in March to-do list:

Arizona Garden in March#gardening #garden #arizonagarden #marchgarden #gardeninginarizona #desertgarden

Planting:

  • March is a great time to plant citrus trees.
  • Plant fruit trees early in the month so they have time to settle in before the heat of the summer. Look for varieties which require less than 400 chill hours, have early maturing fruit, and are self-pollinating.
  • Plant heirloom roses and container-grown roses this month on the north or east sides of yard that receive afternoon shade in the summer.  
  • Plant cold-tolerant trees, bushes, and perennials as well as frost-sensitive plants such as lantana and hibiscus. Plant summer flowering shrubs. Do not over plant, be aware of mature size of plant, and space accordingly.
  • Although the weather is still cool, think twice before planting cool-season annuals this month. It will be heating up soon and their time in the ground will be short. Better to plant warm-season annuals when they are available. 

     

Watering:

  • Check irrigation system and timer. Run system, and inspect all drips and sprinklers for leaks and proper watering. 
  • As temperatures heat up, annual plants will need more frequent watering. Water to a depth of about 6 inches, and allow top of soil to dry out before watering again. 
  • Check containers with a moisture meter or make sure top inch or so of soil has dried out before watering. 
  • Water established citrus trees once every 2-3 weeks. 
  • Water established fruit trees once every 7-10 days.
  • Wateruseitwisely.com is a helpful resource for landscape watering guidelines.

Pruning:

  • Prune frost damage from frost-tender plants such as hibiscus and lantana this month. 
  • If you haven’t already, prune established roses and deciduous fruit trees. Clean up all fallen leaves and debris to discourage disease and insects.  
  • Prune dead branches out of cold-hardy trees and shrubs.  
  • March is the perfect month to prune evergreen trees and shrubs. 
  • Clean up and remove dead or damaged wood and crossing branches on citrus. 
  • Do not prune newly-planted trees or shrubs. 

Fertilizing:

  • Fertilize deciduous fruit trees and citrus if you didn’t do it in February
  • Prepare soil for planting by adding compost.
  • Do not fertilize newly-planted trees or shrubs. 
  • Fertilize trees and shrubs in your yard as needed. Native trees and shrubs do not require extra fertilization. 

Yard to do and clean-up:

  • Thin fruit on deciduous fruit trees. This article will help explain the process. 
  • Remove spent winter-growing annuals. Stressed plants attract pests.   
  • Thin warm-season annuals to keep plants from overcrowding each other. 
  • Clean up and remove dead or damaged wood and crossing branches on citrus. 
  • Remove dead plants in yard. Look at landscape and make note of how plants look and their performance. March is a good time to transplant and move plants within your yard to areas where they get more or less sun depending on the needs of the plants. 
  • Apply a 2-3 inch layer of mulch around base of shrubs and trees. Mulching reduces soil temperatures and adds organic matter to the soil.
