First, let’s learn a little more about Mexican Heather

What is Mexican Heather?

Mexican Heather is a shrub-like groundcover with bright green leaves and small flowers, normally pink, white or lavender colors.

Mexican Heather originated from warmer, Central American climates, so it grows great in warmer weather! For areas that have cold winters like Pennsylvania, Mexican Heather can be planted as an annual.

Mexican Heather goes by a bunch of names, including:

  • False Heather
  • Hawaiian Heather
  • Elfin Herb
  • Cuphea hyssopifolia

Caring for your Mexican Heather

Whether you are growing Mexican Heather as a perennial or an annual, the plant is accustomed to certain growing conditions that should be considered.

Sunlight requirement

Given their warmer weather climate background, Mexican Heather are going to grow the best with part to full sun. Generally, this means that the Mexican Heather will grow best with 4 to 8 hours of direct sunlight.

Mexican Heather temperature needs

Mexican Heather can be grown all over the United States, but since it can’t survive freezing temperatures, it is mostly grown as an annual in most states.

For southern states in growing zones 8 through 11, Mexican Heather may be able to grow all through the winter.

Mexican Heather care: height and spread of plants

In landscape planting, Mexican Heather can grow as wide and high as 2 feet.

For smaller areas, such as container gardening or a window box, Mexican Heather will normally fill in the area you provide it with. Because of this, Mexican Heather acts great as a filler for pots.

Soil type for the best Mexican Heather care

Mexican Heather grows the best in well drained soil, especially if it has a sandy texture. Like most plants, its best if the soil is nutrient-rich, preferably with a mixture of sand, clay and humus.

Mexican Heather fertilizer needs

Feed your plant by building up your soil and/or planting your Mexican Heather with slow release fertilizer — these mini pebbles will slowly release some nutrients for the plant throughout the growing season.

Water soluble plant food can also be used to feed Mexican Heather its nutrients.

How often you fertilize your Mexican Heather, depends on how often you are watering it — for the hot months when you are watering your Mexican Heather almost every day, its important to fertilize the plant multiple times a week (once every third watering).

Disease and pest control

Mexican Heather typically don’t have problems with serious pests, but some more common pests that may feast on your plant are:

  • Spider mites
  • Aphids
  • Thrips
  • Scales
  • Mealybugs

Most of these can be controlled with a soapy or oily spray or even spraying them off with your hose.

Mexican Heather care: pruning Mexican Heather

For Mexican Heather that is being grown as an annual, pruning is much of a factor. Of course, if the plant is getting strangely, it may be healthy for it to be cut back.
