Diascia - Sow, plant, cuttings, care

Diascia, beautiful and fragile flower carpets

Diascias are beautiful, hardy perennials native to South Africa, most often grown as annuals. They settle quickly and form beautiful, dense cushions with tubular flowers, most often in shades of more or less bright pink or purples, from June to October, provided the exposure and soil conditions are favorable. . They are easy to grow in the garden and still resist down to -8 ° C. Mixed with fuchsias, pelargoniums or impatiens, diascias will produce a magnificent rock garden or flower border.

What are the advantages of the diascia garden?

• Easy to grow
• Rapid growth
• Very floriferous
• Long flowering (5 months)

What exhibition?

Sun and partial shade

What soil?

• Drained soil, light and always fresh.

Method of multiplication of diascia?

• Division of the stump, seedlings and cuttings

When to sow them?

• Since the March, in a box under warm shelter - 15 to 18 ° C.

How to sow diascia?

• Prepare a box with lid or terrine to make the seedlings.
• Fill it with fine seed compost.
• Water.
• Sow clearly: seeds well spaced, you can sow in furrows spaced.
• Cover with 2 mm of sieved soil.
• Tamp with a small board.
• Replace the cover.
• Keep the substrate moist.
• Emergence appears within 2 weeks.
• When the seedlings start to gain strength,
• Transplant them individually into earthen pots filled with potting soil.
• Keep moist until planting.

When to plant

• In the ground: from March to April, after severe frosts.

How to plant a diascia?

In the ground

• Work the soil to loosen it without turning it over.
• Add potting soil and possibly mature compost.
In very heavy soils, greatly lighten the earth with sand and deeper.
• Make one or more holes to accommodate the clods of the containers.
• Separate the plants about thirty centimeters.
• For use as a ground cover, place 4 to 6 feet per m2.
• Scrape around the root ball to free the roots if necessary.
• Place the diascia plants
• Recap and tamp down with the soil from the garden with your hand without damaging the roots.
• Water generously.
• Keep the soil cool.

Planting in pots:

• The use of a pot is of course possible,
• For the plant to develop perfectly,
• Add a draining material at the bottom of the pot.
• Add a mixture of peat and potting soil.
• For a tighter effect place 2 feet.
• Water to properly install the stump.
• Then water regularly to keep the soil cool.

Interview :

• Fairly little maintenance for diascias, other than keeping the soil light and cool.
• If, over time, you want to refresh the stump to strengthen it, you can practice division in the spring in areas where perennial cultivation is possible.
• The division can also allow multiplication by replacing the separated part in a suitable place in the garden.

When to cut a diascia:

It is possible to make the cutting in 2 periods:

• Fall cutting: Stored under a heated shelter, flowering will appear normally.
• Spring cutting: Flowering occurs later in summer.

How to make a cutting:

• Choose a segment of a rod about ten centimeters in length, taken from the end.
• In a bucket add gravel and then a bed of fine sand to ensure drainage.
• And fill it with planting soil.
• Remove the leaves from the bottom of the stem and cut it just under a knot.
• Keep a few sap-extracting leaves at the end of the stem.
• Remove flower buds to conserve energy for root crop production.
• Push the cutting into the ground up to the first leaf.
• Water.
• Place the cup in a dark place.
• Keep the soil moist until the plant starts again.
• Keep it in a jar for a few weeks then ...
• Then transplant the young plant into a mixture of garden soil and planting soil.

When to divide a strain of diascia?

As the plant is often grown as an annual due to low hardiness, in colder regions allowing perennial cultivation, it is best to practice by repotting the fall divisions to overwinter and transplant them in summer.

• In early spring
• In autumn

How to divide?

• Use a clean, sharp knife.
Divide the tufts neat.
• Each of the divisions must be provided with the roots of course and a few leaves.
• Untangle the roots and crumble the soil.
• Transplant the divided clumps into pots filled with a mixture of potting soil and garden soil
• You can, if the region allows perennial cultivation and rather when division is practiced in the spring, put the divided stumps back in place directly in the garden.
• Store the pots in a warm, bright shelter.
• Keep the soil moist.
• Put back in place after the cold.

Flowering period of diascia:

Flowering occurs from the month of June and until the first cold: October or November depending on the region.

Flowering of diascias:

• The flowers appear, numerous, in terminal racemes at the top of the stems.
• They are of flared tubular shape sometimes with a tongue, a more imposing petal.
• Most often in shades of white, pink or purple, but not only


Diascia Regescens: height 0.40 m, pale pink flowers, upright habit
Dias. Fetcaniensis: height 0.30 m, bright pink flowers, upright habit

What to plant with diascias?

• Plant with pelargoniums, impatiens and fuchsias

Diascia, garden use:

ATa garden: in rockery, in border, in solid mass. And again on an embankment the plant allows many uses.
• Without garden:
in medium pot of 30 to 40 cm.

Anthems belong to the Asteroid family and are sometimes called В "В daisy or chamomileВ В". The most common species is Anthemis tinctoria or anthem of dyers. But you can also find theATntheput frutescens With white flowers (and other colors) and gray foliage native to the Canary Islands, allowing summer balconies to bloom.

Chamomile is also of the kind Anthemis, with a very creeping habit.

A common feature of anthem is that aromatic, finely cut foliage and its flowers in heads.

  1. Soak your root ball or bare roots in a basin of water.
  2. Dig a hole slightly wider and deeper than the root ball.
  3. If your soil is poor, add some compost.
  4. Praline the roots if they are bare.
  5. Arrange the tree so that the collar is level with the ground.
  6. Recap, tamp and form a bowl.
  7. Water abundantly.

Thealbizia requires little maintenance if it is in the ground. Water young albizia regularly during their first three years. Then water only if the leaves turn yellow during a drought. No need to add fertilizer either, except for potted plants.

In winter, if the temperatures are too low, cover the base of the tree with a layer of mulch and wrap it with a wintering veil.

It is possible to harvest the leaves, but also the flowers! We harvest during the growing season, that is to say between June and September. You can consume it fresh within 24 hours, in a salad, to flavor a dish or as an infusion. To keep the verbena longer, consider drying it. To do this, collect verbena stems that you hang in bunches, upside down, in a dark, dry room. After 15 days, you can put it in an airtight jar.

Scented verbena, officinal, lemon: its health benefits

Lemony, fragrant, officinal. There are several kinds of verbena. What are their health benefits? How and when to use them? We tell you everything.


How to cook verbena, how to store it, when to taste it for optimal flavor. discover all the secrets of verbena.

The cistus cuttings in summer, preferably in August.

  1. Select branches of about 15cm.
  2. Remove the leaves and leave only 2 or 3 at the end of the stem.
  3. Dip them in a cutting hormone.
  4. Plant them in a mixture of cutting soil and sand.
  5. Place the cuttings warm, sheltered from full sun.

Repot and cut the geranium


Repotting takes place every two years in a slightly larger pot. Remove the root ball, untangle it and remove some of the old potting soil that has no nutritional value for the plant. Remove the flowers already open and most of the foliage to lighten the plant, then replace the root ball in the new pot, not forgetting to put a layer of clay balls in the bottom. Fill the holes with fresh potting soil. Tamp the soil a little with your fingers then water generously. The water will finish settling the earth properly.


The best time for cuttings is summer. Indeed, during this season, it is almost impossible to miss the multiplication by cuttings.

Select long, vigorous stems of about 6 inches (15 cm). Cut cleanly with a craft knife at the end and remove the leaves cleanly to avoid injuring the plant. Do not remove all of the leaves, leave the ones on the top of the stem. Remove stipules and buds forming, but leave future buds and young leaves.

Then place your cutting in a pot filled with universal potting soil, making a hole in the middle with a wooden stick. For better drainage, you can add a little sand and mix it with the soil. Water in rain and keep the pot in a room heated to 20 ° C and bright. You will soon see your new geranium take root!

Good to know : for beautiful flowers, remember to add fertilizer in the spring.
