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.

Hybrid Tea Rose
Roses lose their foliage in winter.
They are tolerant of hot weather, but the soil must be kept moist.
They can be propagated from cuttings taken from the current years growth in spring.
Name: Diana, Princess of Wales.
Garden bed type: 40cm Earthenware Pot.
Recommended soil pH: 5.5 - 7.0.
Plant Spacings (centres): 800mm.
Climate: Warm Temperate.
Geography: Southern Hemisphere.
Minimise soil disturbances to maintain a natural soil structure.
In September, remove old mulch, fallen leaves and other decaying organic material. Dispose of them in the compost heap.
Apply a 60mm thick top dressing of home made compost , and add a 20mm thick layer of aged sheep manure. Cover with fresh straw mulch.
Leave for 4 weeks so worm and microbe activity can build up in the soil. Remove the mulch before planting the new rose.
Propagate Roses by taking cuttings from robust current years growth in spring.
Using sharp disinfected secateurs, take a 100mm cutting from just below a node on a stem with a flower starting to die back. Cut off the flower head.
Remove the leaves from the stem leaving only 2 or 3 at the top to continue to photosynthesise.
Plant the cutting in a medium size pot containing organic seed raising and cutting mix. Soak the pot in 10mm deep dilute seaweed extract for an hour.
just rub them out when I find them, with my fingers, but if there are
lots of them, I remove them with a jet of tap water. They seem unable
to regain their place on the buds and shoots of my Roses and (I guess)
starve to death where they land.
monthly foliar spray of aerated compost tea protects my Roses 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.
monthly foliar spray of aerated compost tea protects my Roses from Black Spot.
Alternatively you can spray withan organic fungicide (Eco-fungicide in Australia)..
soil around the rose and avoid getting water on its foliage. Keep the
plant open so that air can circulate and reduce humidity. Black
Spot flourishes in moist conditions.
foliar sprays of aerated compost tea boost the natural defences of
Roses by colonising the leaf surfaces with beneficial microbes.
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.
