Growing Dahlias in Tubs and Troughs 

 By Jack Gott.


There’s more to dahlias than tall flowering types that you see around the shows. There are also types that are ideal for growing in tubs and troughs. I have even grown some in hanging baskets, as a centre plant. They are good in small borders also; even some of the park departments are growing them, to put them in large beds. Some of the variety’s that are good for all this are, Exotic Dwarf a pink single with a darker pink in the centre, it grows eight inches tall this is a lovely little flower (flower size about one and a half inches across). Grow this with one named Omo, this grows the same size flower. A really bright white flower, I think this was named after the washing powder Omo. Then there are the Topmix variety’s in all different colours and the Lilliput types Red, Yellow, Pink, Orange Bronze and Purple. These variety’s you can get from the Garden Centres and Superstores that sell gardening sundries. They were raised in Holland and are grown there like we grow potatoes, and are harvested in the same way; they put them into what I call Dutch Bags with the photo of the flower on the top of the bag. That’s how we get them in the Garden Centres. But one of my favourites is one called Little Dorrit raised in England it has a little flower Lilac with a Purple ring around the centre. I was in Holland last year and we ordered some plug plants from a nursery man Cornelius G de Ree. These were New to the UK, a new type of dahlia raised by a Mr René Rotaveltts from just outside of Amsterdam. They are small patio dahlias of eight variety’s Amazon Bronze, Amazon Lilac, Floral Star, this has tiny Orange flowers about one inch across, Dahlstar Rose with Eye pink semi double, Dahlstar White, Dahlstar Red, Dahlstar Yellow, and a dark leaf one named Jewel Lilac this has a dark Lilac flower with a Black centre one I think will do well in the years to come. They all grow about eight inches tall. If you are going to grow any of the ones I have mentioned, you will need about three tubers to a container of about fifteen inches across. Put some small stones or old broken earthen ware pots in the bottom of the container to help for drainage (don’t forget to make some holes in the bottom of the container to let the water drain out if it gets over watered).

Dahlias like water but don’t like to just stand in it. Then half fill your container with multipurpose compost mixed with some sharp sand, the sharp sand helps to give the compost some body and also drainage. Then place your tubers in the compost, at this stage I mix with the rest of the compost and sand some water gel granules and some slow release fertiliser. This will produce a very nutritious growing media that will help to keep the plants fed through the summer and help to hold moisture. Put this over the top of the tubers, about one and a half inches below the rim of the container, give it a good watering and place in the greenhouse or conservatory until all signs of frost has gone. Then wait for the small shoots to appear. Hope you have some fun trying this out, I don’t think you will be disappointed.
