Planting phlox

Phlox is a perennial flower that is quite hardy. It appreciates rather rich and humus-containing soil, but will still grow fine in ordinary earth.

There are also annual phlox species, one of which is called Drummond’s phlox, which only bloom in summer.

In a pot or nursery container

  • In spring or fall, in a rather sunny spot.

Sowing annual phlox

Sowing annual phlox is easy and quick, and is best done directly in the garden.

  • Try to perform direct sowing in the plot in spring, using a blend of soil mix and garden soil.
  • Keep the substrate a little moist by watering it regularly.
  • When the phlox seeds have sprouted and grown a few leaves, thin them down to about 8 inches (20 cm) distance right from the first leaves, to give the plant a lot of space to grow well.
  • Annual phlox is particularly well suited to garden boxes, pots and pot arrangements.

Planting perennial phlox

Just as for annual phlox, it appreciates rather rich soil.

  • The phlox is planted preferably in fall for species that bloom in spring and in spring for those that bloom in summer.
  • Prefer sunbathed locations.
  • Mix your garden soil with proper flower plant soil mix.
  • Place plants at least 8 to 12 inches (20 to 30 cm) apart.
  • Water regularly.

Multiplying perennial phlox

Perennial phlox is easily propagated through crown division.

Pruning and caring for phlox

Whether you’re dealing with annual or perennial phlox, care is quite easy and usually boils down to watering when the soil is dry.

More regular watering is required for phlox growing in pots, garden boxes or container.

Annual phlox

The most famous annual Phlox is Phlox drummondii.

  • It revels in the sun and prefers rather rich and well drained soil.
  • Regular watering is needed, especially in times of drought.

Perennial phlox

There are a great many phlox varieties and species, but they all have one thing in common: they love sun!

  • Always try to find sunbathed locations or places that only have shade for couple hours.
  • Double-check that your soil is rich enough so you’ll have beautiful blooming.
  • At the beginning of spring, add flower plant fertilizer to the soil.
  • Remove wilted flowers regularly (deadheading).

Phlox in winter

Perennial phlox will grow back year after year but it is best, right after the first frost spells, to cut the foliage short. It would quickly turn black if left on the plant. Protect with a fair layer of dead leaf mulch.

You can pull out annual phlox because they don’t grow back from one year to the next.
