Growing Cactus Dahlia from your Own Seed

Cactus Dahlia

Tips on Saving Seed

  • Choose your parent plant and label the stem with variety and type.
  • Take off the last of the petals or wait for them to fall.
  • Leave the seed head on until it is dry and ready to take off the plant.This can be helped by squeezing excess moisture from the head.
  • Cut the stem about 16inch long with the label and leave to dry for a further couple of weeks.
  • When dry and loose you are ready to take the seed from the dry head .

Seeds Ready to Sow

  • The black seed can be packed in to packets with the name and type of one Dahlia parent.
  • By saving seed this way you do not know the cross pollinator or what you will get. Be selective when you have many plants to choose from next year.
  • For fun you can name the new variety but commercially cultivated varieties must follow naming protocols.
  • With luck you will be happy with the result and encouraged to try again next season.

Plan Autumn Flower Colours

Harrogate-penhill-autumn-shades

Decorative Dahlias provide colour through to the first frost. This dahlia was snapped in the rain at Harrogate Valley Gardens which has a great show of Dahlias in their own raised bed. That may account for the six foot specimens that were on display.

I was taken with the two tone effect of this flower. Many of the other flowers at this time of year are the brash purples, striking pinks or strong yellows. Check now in parks and public place to see what colour schemes work. Then plan your own scheme for next year.

Compost Tea – Tea’s Up

Compost Tea

If you click on the above link Doug will show you on a video how he makes a liquid compost. I use Comfrey leaves in my water barrel when I want an element of organic fertilizer from the compost.

To fertilise blogs we rely on links to other sites. Below are some other gardening related blogs that I read from time to time. We are happy to be linked to other sites.

    Garden Compost and Bokashi

    Bokashi, Japanese composting, is really a fermenting system. It converts your household food waste into a liquid and food remnants that are ripe for final composting. Ripe isn’t a fair word as it smells only of sweet pickle.

    An additive of a lactic acid based micro organisms in a bran carrier is mixed with the food waste in an airtight bin and a culture like a ginger beer plant is created. These microbes include lactobacillus bacteria, phototrophic bacteria and yeast. The fermenting process takes a couple of weeks then the residue can be added to a compost heap or buried even though it can still retain some food colour and shape for a further 4-6 weeks. The liquid can be diluted  with water 1:100 as a fertiliser.

     

    Gardeners Tips

    • Adding bran inoculated with organisms can be an extra expense and it seems hard to find a supplier
    • Adding soil and worms to a normal compost heap achieves similar results.
    • The ability to ‘compost’ meat and other food waste is the main plus
    • The two stage process is a bit of a minus
    • A two bin system makes it easier to switch from food collection to maturation
    • Whilst this may be a bid of a fad it encourages a ‘good green routine‘ and is worth a try.

    Growing Osteospermum – A Great Summer Performer

    My Osteospermum was donated by cutting from a neighbour about 10 years ago. The large daisy shaped flowers appear all summer long in a light purple shade. It would be hard to count the number of flowers each year and I am guilty of not feeding the plant.

    • The plant seems hardy and is evergreen with greyish leaves.
    • I have placed it in the sun to droop over a wall where the soil is well drained.
    • There is a new range of colours and many hybrids including yellows and variegated plants
    • Other common names include African Daisy or Blue-eyed Daisy so you could guess it is a member of the Compsitae family.
    • If you want to see other Osteospermum try the Osteospermum.com web site
    • The lax and blousy habit make them an attraction in seaside locations where they thrive. They can be pruned or trimmed back in September.
    • Dimorphotheca are annuals that look very similar to Osteospurmum but they are South African calendula and part of the Asteraceae family

    Growing Rudbeckia Autumn

    These Rudbeckia are grown as annuals or biennials but great perennial varieties exist. Some grow as low as 12 inches whilst Rudbeckia triloba Brown Eyed Susan is 5 foot tall and Rudbeckia maxima can be up to 10 feet tall.

    • Rudbeckia are easy to raise from seed. Resulting plants are well behaved, easy to care for and flower from August until late Autumn.
    • There are many varieties of Rudbeckia and I recommend hirta and fulgida types.
    • Rudbeckia are used as cut flowers and for growing in pots
    • Also known as Cone flowers most varieties do not need stalking
    • Rudbeckia sullivantii ‘Goldsturm’ and ‘speciosa’ both around 2 foot tall have the RHS Award of Garden Merit. The ‘Green Wizard’ below is under test.

    Plum Picks are Victoria and Czar

    My Victoria plums have just been picked and the majority converted into jam. The wasps had not got at the sweetest fruit so I had a treat for dessert. The tree is now 10 foot tall and I will prune it back next May or June when the danger of fungal infection is reduced.

    Last years Victoria plum crop was so good I decided to try another variety and a Czar tree was planted last Autumn. Czar is a culinary plum with a distinctive blue skin and a sharper taste. This year there was no fruit but next year I hope to do better. Both varieties are self fertile but if you have difficulty there is a great web site for pollination information.

    Companion Plants for Clematis

    Some plants work well together for shape, texture or location and with others it is the colour combination that stands out. This Pholx and Clematis both look exceptional in the late afternoon light. The Phlox adds scent and this vibrant coloured clematis has been in flower since late July.

    Focus on Clematis partnerships

    • Climbing Roses and Clematis make  classic partnerships. Try the dark Clematis jackmanii ‘Superba’ with a light pink Rose ‘New Dawn’.
    • Consider the environment for climbing and parner the clematis accordingly. Warm stone will look  different to a rustic pergola so try Commtess de Bouchaud or Miss Bateman
    • Clematis ‘Nelly Moser’ can look good with Nicotianas
    • I have seen Clematis montana ‘Rubens’ intertwine with a Golden Ivy and hold its own.
    • Careful mixing of Clematis varieties can produce good companions. Clematis tangutica’s yellow lantern flowers and seedheads look fine with large hybrids Clematis Mrs N Thompson has a yellow centre to pick-out the yellow lanterns.

    Tips for Tomatoes in September

    I am picking more and more Cherry Tomatoes as the days get longer. I still have a lot of other vines in the greenhouse with fruit to pick and if they won’t ripen I will try some of these tips. Let me know if you have other methods.

    Encourage late ripening

    • If you haven’t taken the greenhouse shading off, do so and clean all the glass.
    • Bunny Guinness suggests you cover plants with horticultural fleece or perforated plastic.
    • Stop pinching out as it is too late and excess water can be transpired through the new leaves to help avoid splitting.
    • Reduce the plants work load by selecting the fruit you want to ripen and take the rest off.
    • If you pick green tomatoes hang vines in a dark dry place to ripen.
    • Wrap a tomato in newspaper and put in a drawer  or cardboard box. Tomatoes ripen best in the dark and sunlight will make the skins get tough.
    • Put a banana in with green tomatoes will speed up the ripening/decay process
    • Pick green tomatoes as they start to change colour. Hard, dark green tomatoes get to a point where they won’t ripen and are only good for Chutney.

    The Empty Vegetable Plot

    Garden Lime

    Autumn is a good time to plant a green manure crop in your empty vegetable plot. Green manures are sown deliberately to be dug back into the soil before they flower. This helps improve fertility, suppress weeds, stop leaching and soil errosion and helps condition the soil.

    Empty Plot Tips

    • Clear up debris and weeds and make the plot tidy.
    • Test soil and add lime to prevent it becoming too acid and reducing future crops.
    • Leave pea and bean roots to rot down.
    • If soil is heavy dig and leave large clumps for the frost to break down
    • Replan paths and cropp rotation for next year. Do not walk on wet ground.
    • Incorporate rotted compost.
    • Mulch the asparagus bed.
