                                    (An RHS Long Term Trial)

There were 137 entries in this Long Term trial of Garden Chrysanthemums, which were assessed
by the Chrysanthemum Committee in 2007 for the Award of Garden Merit.

Trial Objectives:
To assess, compare and demonstrate a range of cultivars submitted by individuals, raisers and
nurserymen, following preliminary assessment by the Chrysanthemum Committee.

Entries:
• 4 Ground hugging cushion mums (Nos. 1-4)
• 52 Cushion mums (Nos. 5-56)
• 2 Belgian mums (Nos. 57-58)
• 32 Spray chrysanthemums (Nos. 59-89)
• 28 Disbudded chrysanthemums (Nos. 90-117)
• 20 Hardy chrysanthemums (Nos. 118-137)

The Chrysanthemum Committee judged the entries in this trial on 21 August, 11 September, 25
September and 9 October 2007 for the Award of Garden Merit, using the following criteria:

              Vigour : habit : health : length of flowering period
              colour/ colour stability and quality of bloom : weather tolerance

The Committee awarded the Society's

AWARD OF GARDEN MERIT (H3) to the following:

Cultivation:
The trial plot was tractor rotovated in October 2006 and the plot prepared and sown with Caliente
Mustard. To reduce the effects of soil borne pest and diseases that Chrysanthemums can be
susceptible to, it is important to sterilise the soil. Previously a chemical sterilant, Basamid, has been
used, for 2007 Wisley introduced a green manure, Caliente Mustard, to their programme. This is
specially bred as a soil improver with the added benefit of having bio-fumigant properties.

In April 2007 the Mustard was watered before being mown, tractor rotovated and sealed under black
polythene for 2 weeks. Once in contact with the moist soil the chopped plant material broke down to
release biologically active compounds that help to suppress weeds, root rot and nematodes (eelworm).

The polythene was removed in early May. The ground was then hand raked and marked out. Black
membrane was put down and support posts erected. This is the first year that the Chrysanthemums
have been planted through membrane, used to avoid splash back when watering the trial, which could
increase the transference of disease.

The spray and disbudded chrysanthemums were planted on 15 May and the cushion 'mums on 30
May. On 23 April the spray and disbudded entries were ‘stopped’ by removal of the terminal bud,
encouraging plants to bush out and hastening development of side branches, which will bear the
flowers. Cushion 'mums were pinched out to encourage bushy plants and even flowering on 15 June.
Spray stocks, after initial ‘stopping’, were allowed to grow naturally; disbud entries after initial 'stopping',
continue to be disbudded so that only one flower per stem is produced.

Chrysanthemums need regular watering to obtain the best results. These plants were never allowed to
dry out and as the plants grow, the amount of water was increased. Plants were sprayed routinely for
pest and disease control.

Findings:
The trial performed much better in 2007 than it had done in 2006. The occurrence of White Rust
was minimal due to a careful preventative spray programme and cultural care when receiving fresh
stock and propagating material at Wisley. However a higher level of Eelworm was found in the trial
this year. It was a particularly wet summer at Wisley in 2007 and Eelworm can spread more
rapidly when the foliage remains wet.
http://www.rhs.org.uk/advice/profiles1001/leaf_bud_eelworm.asp
Eelworm is usually eradicated by hot water treatment of stools when they are lifted at the end of
the season. In future those senders without the facilities to hot water treat stools prior to taking
cuttings will be asked to send stools for hot water treatment and propagation at Wisley, rather than
sending untreated un-rooted cuttings the following spring.

Some random patches of entries were considered to be growing undersize in 2007. The
committee thought this may be due to the fabric through which the entries had been planted. The
fabric mulch had proved effective in preventing splash back and related fungal spore spread, but
there was some concern that the closeness of the weave resulted in prevention of water
penetration. It was agreed that in 2008 the same material should be used but with irrigation lines
placed beneath to overcome problems relating to lack of water penetration.

It was also considered that the Caliente Mustard, incorporated in the soil prior to planting, may not
have broken down sufficiently. This could have caused stunted growth by withdrawing available
Nitrogen from the Chrysanthemums in the early stages of their vegetative development. It was
agreed that the Caliente Mustard would be used as a soil improver with bio-fumigant properties
again in 2008 with a few modifications to the programme of use. As the mustard crop had not
been lush enough in 2007, nitrogen fertiliser would be applied on sowing and again in February to
encourage lush, juicy material for incorporation in April 2008. At the time of incorporation there
would be a third application of Nitrogen after flailing to assist break down of the incorporated
material, then a final application before planting out trial entries. Once the mustard was
incorporated it would be covered for 3 weeks as opposed to 2 to ensure the green material break
down sufficiently, this would aid the bio-fumigant properties of the mustard and ideally prevent the
mustard from holding the nitrogen away from the Chrysanthemum plants.
