DENDRANTHEMA ‘Pumpkin Igloo ’

Perennial Mum

Truly hardy garden mums, flowers for over a month, flowering in the UK normally begins around September and continues into November the flowers only being spoiled by the Autumn frosts and rain.

Low growing mounded habit ideal for front of border, ground cover near pathways and border edging, ideal also in containers and patio planters and the other good thing is that you do not need to throw these out, tidy up and they will come back for next year.

Available in a range of colours, from Aris Horticulture USA. Distributed by Must Have Perennials.

So when selecting subjects  for plant breeding you can see it’s important to select for colour and height and also take into account today’s market trends in plants.

Having a series that has variations in colour, flowering either singles and doubles is good and makes it easier to get a take up commercially if there are more to follow.

So if you have different selections of  Dendranthema / Chrysanthemum growing in your garden its worth taking some seed from each, germinating these and growing on to see if you get anything different, imagine a shorter whole new range with different colours, flower size etc.

As you can see from the picture above new cultivars can be created be from plant breeding and crossing. It’s a long process, its good to look at plants in your own garden, looking for improvements that may be possible.

You see with the Dendranthema by getting a shorter flowering plant it makes the plant more fitting for todays market and also for growers more plants can be transported on a lorry in flower as its shorter so it’s a good growers plant.

You must keep records of any crossings you make. Be critical when making a selection, be prepared to be strict when discarding plants.

Pictures are important so get the camera ready to take photos to record your work.

For developing your new plant breeding selection or new plant discovery I can offer full trialling and new plant development service more details available on my website.

Also pictures can be taken, recorded and stored if needed.



Now the weather has now changed to cooler conditions the clocks have changed we had the first frosts of the season, November has started quite bright, but with clear skies comes the likelihood of frosts at night.

The monthly forecast is looking still quite mild with a chance of high pressure at towards the end of the month which will lead to cooler temperatures and frosts at night.

There is still work to be carried out in the garden.

Plants to look for in November




Geranium Rozanne®  – will continue flowering until frosts.

Hedera – variegated forms



Ophiopogon planiscapus

Saxifraga fortunei

If you have planted autumn bedding you will still need to keep all baskets and tubs watered and checked each day but reduce amount of watering keeping them moist and not wet.

Planting tulip bulbs, Daffodils, try some in tubs and patio plants mixed in with bedding to give early colour.

Look out  daily for slugs and snails check your local garden centre for best controls, an idea I have seen is to place an old roof tile on ground, snails go under here during daytime just turn over and pick them off each day.

During this month as the Dahlia finish it will be time to lift and store, lift, and put in a tray to dry out somewhere cool and dry but frost free, when dry plunge in sand or compost and store for winter in frost free shed or garage, keep cool not warm or the tubers will start to shoot.

Begonias should also be brought in, dried out and stored in similar way as Dahlia.

Good time to plant new perennials they will establish before the winter and get a good start in the spring and be ready to have some resistance to drier conditions as they will be more established.

Divide perennials and alpines looking tired and not flowering as well, like Crocosmia.

Regular weeding  and hoeing whenever you can will keep weeds under control they will continue to grow during periods of mild weather.

Start winterising the garden insulating plants like Tree Ferns and Banana’s.

Ideal time now to plant Roses but not where they have been planted before.

Good time to move shrubs and trees if needed.

Bare root  deciduous hedging, trees and shrubs will become available for planting during this month.

Pruning deciduous trees and shrubs can start during this month. Evergreens are best left now until the spring.

Good time now for seed collection now, storage is important, remember cultivars will not come true to type.

You can sow sweet pea seeds now for early flowers next year, sow more in spring for later flowering.

Look out for Vine Weevil damage, damage shows when plants start to wilt, on inspection roots will have been badly eaten

you may also see white c shaped larvae, apply a biological control, plants in containers are unlikely to recover.

Sedums and Geraniums can be badly affected.

Start mulching borders.

Leaf clearing will start now as trees and shrubs start to turn and loose leaves.

Continue to mow lawn regularly, while weather is open and temps are above  5°c grass will keep growing but do not cut as short as you would in summer, keep edges neat,

Keep clearing leaves off lawns as they will block light, hold in moisture increasing risk of disease, moss and algae.

If you have a pond then still keep water circulating, using waterfalls and pumps, fountains etc, until cold weather has started.

Good time to clean filters, skim leaves off pond surface and rake out of pond.

Reduce fish feeding and stop altogether when cold weather starts.

Trim back marginal plants.

In the Greenhouse, clean out all old plants and clean and disinfect greenhouse with Jeyes fluid or citrox.

For vegetables there is still time to plant leeks from leek plants and onions from sets.

Time to plant broad beans, Garlic,  and spring cabbage plants if you can find them, look in local garden centre.

You can grow herbs over winter if you dig some up and move indoors, they will need good light, don’t overwater.

Sow peas – Meteor sown outdoors will give an early crop next year.

Plant Rhubarb crowns, Raspberry canes, Blueberry, Black and red currents.

Time to paint fences and sheds carry out any repairs, in the greenhouse replace any broken glass needed before winter.

Pressure wash decking, put away furniture.

Patio heaters and chimineas may still be needed for those bright clear nights!

Good time for planning any new hard landscape projects to carry out over winter.

Build a compost heap for leaves and grass clippings.

Digging over soil will expose pest larvae to birds and improve soil structure, do this for all vacant vegetable garden soil in readiness for next year. Add plenty of organic compost from your own compost if you have it.

Put out food and water for birds during cold periods.

If you have a bonfire remember to check that you do not have a hedgehog in side! – they need gardeners help right now as populations are decreasing.
