All your plants should be in 5 inch / 125 mm pots by the middle of May. Stop plants when 5 to 6 inches, 125 mm 150 mm, tall or after 4 -5 pairs of leaves depending on the number of main flowering stems you wish to have. Plants, whether seedlings or cuttings, should now be in your cold house or frame hardening off; do protect from frost!, if real chill threatens a fleece covering will do a great job.
Take any late cuttings should you need to produce more plants. These will grow on but not begin flowering until, probably, mid-August but will consequently go on longer if there are no frosts in late October / early November. Keep your hygiene programme going.
In the south and south-west start planting out dahlia plants when the weather is suitable and there seems to be no risk of a late frost. As things are at present with the weather I anticipate beginning the planting out around the 3rd weekend in May.

Nursery Update
Back in January I posted a video clip of the nursery, - http://bit.ly/lyeK6i - that showed it to be a bit overgrown!
I weed killed in March and the first picture shows the results, this is the "before" cultivating last week.
I under estimated the hardness of the ground and over estimated the capability of the rotavator; result, instead of taking two days it took four. Still; job done! See below
Could do with some rain on it now before planting out begins, probably around 3rd weekend in May.

Rooted cuttings preparing for dispatch
We are now in our busy period of packing and dispatch.
We put rooted cuttings in polythene sleeves before packing in the cartons.
Here are rooted cuttings in the propagating trays before being transferred to the polythene sleeves.
Now in polythene sleeve ready to be packed into the carton.
Both rooted cuttings and the more mature ex 90mm pot plants are packed tightly into the carton and air pillows/bubble wrap is used to fill the voids to prevent any movement during transit.
Rooted cuttings are sent by Royal Mail in flat cartons. Plants are sent by next day delivery courier in larger, but essentially flat, cartons.
Just heard that one package sent on April 7th by Royal Mail First Class recorded delivery still hasn't arrived, they say "Your item is still in transit"; words fail me.

Demand for Dahlias
Demand for dahlias appears to be up this year. I have already sold out of a number of cultivars and, speaking with other growers around the country, they seem to be in a similar situation.
Another pointer to the increasing popularity of the dahlia!
Alternatively, of course, it could just be that many dahlia lovers have now checked their tubers and found them to be damaged beyond redemption by the severe weather in November and December!

New web site for Spring 2011
If the Spring time is not busy enough with cuttings, potting on, preparing orders for dispatch and so forth I thought that a spring clean of the web site was due, so there is a new one!
I hope you find this easy to navigate and welcome any comments that you may have.

Dahlia jobs in April
Keep on taking cuttings until you have made sure that you have sufficient for your needs, although, the back end of April is getting a bit late for the plants to mature fully when planted out. (However, I shall be taking late cuttings this year in an experiment to see how I can further the flowering season by planting out very late in a poly tunnel).
Pot up the rooted cuttings into 90mm pots using a general purpose compost or John Innes No1. Prick out dahlia seedlings as soon as they are big enough to handle and put into trays or pots.
By mid-April some of the early cuttings will now be getting well ahead in their 90 mm pots; it's time to pot them on into 125 mm pots so that their growth is not set back. Especially important if you have bought ex-pot plants from a commercial grower.
Keep the hygiene programme going! Any plants found to be diseased should be destroyed (burnt) as quickly as possible to prevent spread.
Plant out divided tubers about the middle of April.

Wisley Open Day - March 4th
I took a little time out today and went to Wisley Gardens who had an open day to attract new members to the RHS. The National Dahlia society had a presence there, along with other specialist plant societies, who I met with.
Of course, all the societies were promoting membership which I think is so important for the specialist grower; apart from the wealth of information and advice that one can get from other members it is also important as it helps promote the particular plant type and maintains and, hopefully, increase popularity.
Dahlias reigned supreme through the 60's and 70's and then suffered a decline in popularity. For some reason they gained an unfair reputation for being difficult to grow, and there was some criticism for them being water hungry. However, they are now becoming more popular as people realise that they are actually not difficult to grow and, whilst they do require water, can be grown with careful and economical irrigation. Last year I planted mine out at the very beginning of June, it rained a little the following day (which was a blessing) but then not until late July. Apart from 2 or 3 plants in one area I did not irrigate at all. This forces the young plants to put their roots down deeper searching for moisture and creates a much stronger root system.
Now people are seeing them in a different light; the different colours and shades, the different shapes and sizes; there are dahlias to suit everyone's taste.
There has also been a real focus on exhibition cultivars which, in my view, has tended to put off anyone that just wanted splashes of vibrant colours in their garden. This trend, I believe, is beginning to change with much more publicity on these wonderful plants for gardens and borders.
And don't forget that dahlias are fantastic for cut flowers. Between the end of July and into October a single plant could produce as many as 16 to 20 blooms; some cultivars are more prolific than others and any supplier will advise on this. So, a dozen dahlias in the cut flower garden could yield 180 to 240 blooms over a 8 to 10 week period; all from a plant costing just a few pounds, what a return! The important thing to remember is that once a dahlia starts to bloom they must be either cut for the vase or, as soon as the petals begin to die away, dead headed; the more they are cut the more they will flower.
At the beginning of September why not allow a few heads to die on the plant and collect the seeds? As soon as the seed head is ripe remove the seeds and spread thinly on sheets of newspaper, or other absorbent paper. Separate the 'chaff' and, when completely dry, store in an envelope until the Spring. Sowing in early April will yield plants ready to go out into the garden in early June when all danger of frost has past. Scatter the seed onto seed compost in a tray and water lightly. Seedling will start to appear in 4/5 days and by around day 14 should be ready to be pricked out into a 90mm pot. As dahlia cultivars are all hybrids the plants that grow from these seed will not be true to the parent plant.
Flowering will start in mid to late July and can be quite exciting with the anticipation of what your seeds will produce!
