Welcome to my website about growing ornamental plants organically. Few gardens work well without flowering plants, and in an organic garden where insect activity is encouraged, they are vital. My flowering plants bring pleasure by filling the air with wonderful fragrances and stimulate the senses with their beauty............................................John Ashworth 26th December 2015.
Growing Purple Coneflowers
Latest Update 11th May 2016.
Binomial Name: Echinacea purpurea.
Classification: Herbaceous perennial.
Garden bed type: Drip line irrigated.
Recommended soil pH: 5.5 - 6.5.
Plant Spacings (centres): 600mm.
Climate: Warm Temperate.
Geography: Southern Hemisphere.
The photo shows 2 purple coneflower plants grown from seed earlier this year in a propagator and planted out as seedlings in an Ecobed. They have grown well in their first season, and I will cut them back in spring before replanting them in one of my drip line irrigated garden beds.
They are a handsome plant and drought tolerant.
Pollinating insects such as honey and native bees love them, and they will be useful additions to my herb and fruit beds.
They should be cut to the ground if they wilt badly in excessively dry conditions.
Regular deadheading will promote growth of new flowers.
I spray all my plants regularly with aerated compost tea to protect them from airborne pests and feed them through their foliage.
Prefers rich organic soil.
Minimise soil disturbances to maintain a natural soil structure.
Feed the Soil.
In September, remove old mulch, fallen leaves and other decaying organic material from around the plants. Dispose of it all in the compost heap.
They can be propagated from cuttings taken from a mature plant's root system.
Make sure these root cuttings have plenty of fine roots attached.
Plant them in the Eco propagator and water them in well.
Once the cuttings have started to grow foliage, move some of
the mulch in a prepared bed to one side and dig holes twice as big as each plant's
Place a plant in each hole,back fill with compost and water them in well.
They must be kept well watered as they mature during the first summer, but the drip irrigation will take over after that.
As soon as flowers die back, deadhead them to promote growth of more flowers.
If a plant becomes severely distressed or damaged due to drought or extremely hot, windy weather, cut the plant's foliage down to the ground. It will recover and renew its foliage when milder conditions return.
Spray the foliage every month with aerated compost tea to help feed the plant and help resist pests and diseases.
Organic Pest Control.
Purple coneflowers are usually pest and disease resistant, but if they are effected, these measures may help :-
mixed with water, Bacillus thuringiensis becomes a potent (organically
certified) killer of butterfly caterpillars. It is sprayed onto the
plants leaves, and when ingested, kills them by
releasing toxins into their gut. They stop feeding and die within a few
monthly foliar spray of aerated compost tea protects my plants from Powdery Mildew.
solution of 1 part cows milk to 9 parts water makes a reasonably
effective organic pesticide against powdery mildew. However, it needs
to be applied early before this fungi gets well established, and
frequently to keep it in check.
foliar sprays of aerated compost tea boost the natural defences of my plants by colonising the leaf surfaces with beneficial
These microbes defend the plant against airborne pests and diseases.
proper soil preparation including regular applications of home made
compost boosts the community of beneficial
microbes, which defend the plants roots against plant pathogens.
