Alternatively, you can grow sweet almond bush in pots that can be moved indoors as needed and returned outside after last frost.<\/p>\n

\n
\n

How to Grow<\/h2>\n

When you replicate its natural habitat, A. virgata<\/em> rewards you with an abundance of flowers and an outdoor living space infused with perfume.<\/p>\n

\n
\"A\"A<\/figure>\n<\/div>\n

Sweet almond bush grows rapidly and reaches mature dimensions in three to five years when its cultural requirements are met.<\/p>\n

Let\u2019s discuss how to accommodate its needs.<\/p>\n

Climate<\/h3>\n

In its native range of northern Argentina, sweet almond bush grows in tropical to subtropical conditions.<\/p>\n

Summers are hot and humid, with temperatures between 86 and 104\u00b0F, and seasonal rainfall.<\/p>\n<\/div>\n<\/div>\n

Winters are mild, with average temperatures between 50 and 68\u00b0F and only occasional light frosts.<\/p>\n

In cultivation, this species performs best in similar conditions.<\/p>\n

\n
\n

Light<\/h3>\n

Sweet almond bush prefers a location with full sun<\/a><\/strong> to support optimal growth and flowering.<\/p>\n

\n
\"A\"A<\/figure>\n<\/div>\n

Aim for at least six hours of direct sunlight per day. Adequate light also helps to dry the soil surface between waterings, reducing the risk of root rot.<\/p>\n

Soil<\/h3>\n

The ideal soil is organically-rich loam with a pH of 5.6 to 7.8. It should be loose, airy, and well-draining.<\/p>\n

If you\u2019re cultivating in containers, select a potting mix that is loose, moisture retentive, and drains well.<\/p>\n

Water<\/h3>\n<\/div>\n<\/div>\n

Provide consistent moisture during the first two to three years after planting. Water when the top two to three inches of soil are dry, especially during hot weather.<\/p>\n

Once established, A. virgata<\/em> has above-average drought tolerance. Avoid overwatering as this can lead to root rot. Mature plants generally need irrigation only during a protracted dry spell.<\/p>\n

\n
\n

Fertilizing<\/h3>\n

While this shrub is not a heavy feeder, it benefits from a yearly application of an all-purpose, slow-release, granular fertilizer with a balanced N-P-K ratio, such as 10-10-10, to support overall health and blooming.<\/p>\n

Where to Buy<\/h2>\n

Sweet almond bush isn\u2019t commonly found at big-box garden centers, but you may be able to source it through specialty nurseries in Zones 8 to 11 or from individual growers via plant exchanges.<\/p>\n

Maintenance<\/h2>\n

With regular pruning, sweet almond bush can be shaped into a multi-stemmed shrub or trained as a small tree. In containers, trimming helps control size and maintain a tidy form.<\/p>\n

The best time to prune is in midsummer, after the first flush of flowers fades.<\/p>\n

\n
\"A\"A<\/figure>\n<\/div>\n

Because this plant blooms on new growth, cutting branches post-bloom often encourages a second round of flowering.<\/p>\n

Deadheading spent flower stems<\/a><\/strong> throughout the growing season also supports prolific reblooming.<\/p>\n

Remove any damaged, dead, or pest- or disease-affected branches as needed.<\/p>\n

In cooler regions, where the shrub dies with the first frost, cut it back to the ground and dispose of the debris to avoid harboring garden pests and pathogens over the winter.<\/p>\n

Apply a loose, airy two- to three-inch layer of straw mulch<\/a><\/strong> over the root zone for winter insulation.<\/p>\n

For potted specimens in areas that freeze, you can take them indoors before the first frost to enjoy as a houseplant, returning it outdoors the following spring.<\/p>\n

Choose a location in bright, indirect light, and water when the top few inches of soil dry out.<\/p>\n<\/div>\n<\/div>\n

For container-grown plants in freezing climates, bring them indoors before the first frost. They can be kept as houseplants in a bright location, watered when the top few inches of soil are dry.<\/p>\n

Alternatively, allow frost to trigger leaf drop and store the pot in a dark room at around 60\u00b0F where it will remain dormant until you put it outside in the spring.<\/p>\n

\n
\n

Water infrequently, just before the pot completely dries out.<\/p>\n

Propagation<\/h2>\n

The best ways to propagate sweet almond bush is by taking cutting or by air-layering.<\/p>\n

If you don\u2019t have a shrub to work with, you can purchase a nursery start from a reputable grower.<\/p>\n

From Cuttings<\/h3>\n

To propagate sweet almond bush by cuttings:<\/p>\n

    \n
  1. Use clean shears to cut a six-inch length from healthy tip growth.<\/li>\n
  2. Remove the leaves from the bottom three inches of the stem.<\/li>\n
  3. Fill a well-draining six-inch container three-quarters full of loose, well-draining potting medium.<\/li>\n
  4. Use a pencil to make a three-inch-deep hole in the center of the potting soil.<\/li>\n
  5. Dip the cut end into rooting hormone powder if you have some, and place the stem into the hole, three inches deep.<\/li>\n
  6. Tamp the soil to hold it firmly in place.<\/li>\n
  7. Water until it runs from the drainage hole.<\/li>\n
  8. Place the pot in bright, indirect sunlight indoors or direct sunlight outdoors.<\/li>\n<\/ol>\n

    When new foliage sprouts, the cutting is ready to transplant out into the garden or into a permanent container.<\/p>\n

    By Air Layering<\/h3>\n

    Air layering is a propagation method that encourages roots to form on a wounded section of a branch while still attached to the parent plant.<\/p>\n

      \n
    1. In midsummer, select a mature, pencil-thick branch with new growth.<\/li>\n
    2. Choose a one- to two-inch section with one or more leaf nodes, and snip off any leaves.<\/li>\n
    3. Make two shallow circular cuts, just penetrating the outer bark, around the stem, one to two inches apart, and connect them with a vertical cut.<\/li>\n
    4. Gently lift and remove the outer layer of bark from the one- to two-inch \u201cwound.\u201d<\/li>\n
    5. Wrap a generous handful or two of wet sphagnum moss all the way around the wound and press it in place.<\/li>\n
    6. Cover the moss with plastic and secure both ends with twist ties.<\/li>\n
    7. Check moisture weekly, rewetting the moss with a spray bottle as needed to keep it consistently moist.<\/li>\n
    8. When white roots appear, remove the plastic but keep the moss in place.<\/li>\n
    9. Sever the rooted section just below the new root mass using clean pruners.<\/li>\n<\/ol>\n

      You should now have a leafy stem with a root mass at the bottom ready to transplant.<\/p>\n

      Transplanting<\/h3>\n

      To transplant sweet almond bush into the landscape, work the soil to a depth of eight to 12 inches until it is loose and crumbly.<\/p>\n

      Set the crown, where the roots and stem(s) meet, slightly above the soil surface, backfill with soil, and water in well.<\/p>\n<\/div>\n<\/div>\n

      After transplant, maintain even moisture, watering when the top few inches of soil feel dry and rain is not in the forecast.<\/p>\n

      Pamper your sweet almond bush for the first couple of years. After that, it is drought tolerant and shouldn\u2019t need supplemental water unless there is a drought.<\/p>\n

      \n
      \n

      Pests and Disease<\/h2>\n

      A. virgata<\/em> is not prone to pests or pathogens in the landscape.<\/p>\n

      \n
      \"A\"A<\/figure>\n<\/div>\n

      However, the plants may be visited by aphids<\/a><\/strong> in overly humid conditions, and spider mites<\/a><\/strong>, and\/or\u00a0whiteflies<\/a><\/strong> in hot, dry environments.<\/p>\n

      Damage from these sapsucking insects includes leaf yellowing, wilting, and stunted growth.<\/p>\n

      Address infestations with a strong spray of water from the hose and applications of neem oil as needed.<\/p>\n<\/div>\n<\/div>\n

      Sweet almond bush may be vulnerable to root rot in wet soil. Signs of rotting include the softening of foliage and roots, wilting, and a foul odor.<\/p>\n

      If caught early, healthy portions may be salvageable. Grow in well-draining pots or ground soil and avoid overwatering.<\/p>\n

      \n
      \n

      Lovely and Long-Blooming<\/h2>\n

      When a shrub repeat-blooms throughout the growing season, it is a valuable asset in the midsummer-to-fall landscape, well worth the minimal maintenance required.<\/p>\n

      \n
      \"A\"A<\/figure>\n<\/div>\n

      With its substantial size, gracefully arching branches, lovely blossom spikes, and heady fragrance, the long-blooming sweet almond bush is destined to play a starring role in Zone 8 to 11 landscapes.<\/p>\n
