Very Easy, Very Early Natural Season Garden Mums Electra ™ Amber NEW! Tanya ™ Yellow ADVERTORIAL VERY EASY, VERY EARLY VARIETIES Regions Yellow Orange/ Bronze Red Purple Pink/ Lavender White Both North & South Tanya ™ Yellow Electra ™ Amber Samantha ™ Red Arlette ™ Purple Demi ™ Pink Shannon ™ White North Brittany ™ Yellow Keeley ™ Orange Debbie ™ Hot Pink South Michelle ™ Gold Hannah ™ Orange Edith ™ White Very early natural season garden mums have been an important breeding goal for decades. In the 1970s and 1980s, natural season garden mums were the only way garden mums were produced. Then, in the 1990s, retailers wanted sales in August and even July. Growers began blackclothing garden mums, as was done for pot mums, to meet this earlier demand. And some growers found it easier to keep blackclothing their mums for fl owering in late August and September. For growers who do not have a greenhouse equipped with an automatic blackcloth system, it is necessary to manually put blackcloth over the plants each night and take it off each morning. This takes a signifi cant amount of time and effort, and some growers would prefer not to do this at all. Natural season production is still the best way to go, if there is no need for fi nished garden mums in early or mid-August. How to make Very Early also very easy There are some varieties available today that can fl ower naturally in mid-August. But these varieties require special treatment with Florel ® and Fascination ® plant growth regulators to get plant growth before they fl ower. These varieties are also challenging stock plants which makes cutting production diffi cult. Although the varieties do not need blackcloth for fl owering in August, they do require quite a bit of effort to prevent premature fl owering to grow a decent plant. At Syngenta Flowers we have worked to select varieties that can fl ower naturally in the later half of August and are also able to size up before fl owering without special chemical treatments. In addition, we look at stock plant production to secure a reliable supply of cuttings to growers. This perfect combination of growth and early fl owering is not easy to come by, but we now have a group of varieties that can be ready to ship with bud color in Week 34 or 35 without blackcloth. We have seen this occur from north to south in the United States and even during the hot season of 2018. What are the Very Easy, Very Early varieties and how do I grow them? There are several new, as well as some existing varieties, that create the group for naturally fl owering in August. See the table below for options in each color group, and some regionally specifi c additions that can be used. Crop culture is very easy as well, utilizing standard mum propagation with night interruption mum lighting plus one Florel ® application eight to 10 days after stick. Transplant and put plants outside between Week 24 and Week 26. Plan for one rooted cutting per pot in 8-inch or 9-inch pots and three rooted cuttings in 12-inch or 14-inch pots. Grow as you would any garden mum with standard fertilization and no special growth regulators. Plants will size up and have color for shipping in Week 34 or at least early in Week 35.
