美国 德尔大丽花 Dahlia Del – 明尼苏达小型个人大丽花苗圃

明尼苏达社区花园里的小型大丽花球根苗圃

德尔大丽花（Dahlia Del，也称 Del’s Dahlias）是一家位于美国明尼苏达州明尼阿波利斯市（Minneapolis, MN）的小型个人大丽花球根专营苗圃，2017 年由 Del 创办，主站域名为 delsdahlias.com。苗圃以社区花园（Prospect Park 一带）和明尼阿波利斯、圣保罗（St. Paul）周边的社区园地为种植基地，会员可凭账号进入在线目录选购大丽花球根与配套资材。所有在售球根均经 Del 亲自选育、品控并独立包装，发货时确保每个球根至少含一个可萌发的芽眼（viable eye），命名也尽量核对后才贴标。苗圃不设广播邮件订阅，营业动态仅在该站首页持续更新。

会员制目录、预购与球根质量承诺

德尔大丽花的目录（Catalog）只对会员开放。每年上线的预购（pre-sale）通常在冬季开启，售完即止；3 至 4 月还会再依据越冬情况放出二次补货（restock）。会员福利包括目录预购资格、针对性信息推送、个性化客服、积分奖励（Rewards），以及会员专属的历史更新档案。付款渠道为 PayPal 与 Stripe 信用卡。明尼苏达州居民需按目的地税率缴纳销售税。发货范围限定美国境内，起运时间从 3 月中旬开始，以天气情况为准，球根、托盘与插盘的运费按订单金额分档计算（20 美元以下 12 美元、20 至 50 美元 17 美元、50 至 100 美元 24 美元、100 至 200 美元 28 美元、200 美元以上 35 美元）。资材类（托盘、插盘、面包烤盘）因体积重量较大，仅限明尼苏达、北达科他、南达科他、威斯康星、爱荷华五州区域运送。

四季种植工作流：越冬、扦插与起球

每年秋末 Del 会把全部大丽花起球（lift tubers），剪短茎秆、分丛后送入冷库贮藏。冬季期间，库内温度维持在 4 至 10°C 之间（参考冷藏箱外置温度计读数），相对湿度保持稳定，避免球根脱水或发霉。早春（通常是 3 月）将冷藏球根取出，移到温室穴盘中催芽；带芽的块根切成单芽或多芽茎段，插于湿润的穴盘介质，待生根后再移栽到社区花园的露地。整个生长季里 Del 会同步做扦插扩繁（cuttings）和分株（dividing clumps），以备下一季销售与赠送。从站内视频教学资源看，这些工作步骤与「如何种植」「如何切茎扦插」「如何越冬」「如何分球」等通用做法一致，并对外公开推荐给家庭种植者参考。

明尼苏达大丽花协会、美国大丽花协会与本地花展

Del 是明尼苏达大丽花协会（Minnesota Dahlia Society，简称 MDS）和美国大丽花协会（American Dahlia Society）的注册会员。每年 8 月底至 9 月初，明尼苏达州博览会（MN State Fair）和 Bachman’s 秋季大丽花展均由 MDS 主办，Del 会带自家评选出的获奖大丽花参赛并展出。家附近 Bachman’s 是明尼阿波利斯历史悠久的大型园艺中心，与 MDS 联系紧密，是本地大丽花爱好者最重要的年度交流场所之一。除展出外，未参评或未被选中的花束会被捐赠给 Our Lady of Peace 临终关怀机构、Episcopal Homes 老年社区，以及其他需要提振精神的社区伙伴；偶尔少量鲜切花也会经 Soderberg’s Floral and Gift 代售。

积分计划、社区互助与可借鉴的种植资料

德尔大丽花的积分计划（Loyalty）已上线，会员消费 1 美元积 1 分，可兑换折扣券；共设 Basic（0 分）、Silver（250 分起）、Gold（400 分起）、Platinum（550 分起）四个等级，每个等级对应不同的兑换折扣。站内的 Resources 页面长期收录公开的大丽花分类、尺寸、花型、色彩指南（American Dahlia Society 分类指南）、越冬、分球、切茎扦插等教学视频，以及 Creekside Dahlias、Dahlia Addict、Dahlia University、Dahlia wiki 等同业资源链接，供家庭种植者与竞赛型玩家共同使用。若本站暂时缺货，Del 也建议买家先去 Creekside Dahlias 与 Dahlia Addict 看看——这两个独立平台常年整理各家品种目录与待售信息。

A Small Dahlia Tuber Nursery in a Minneapolis Community Garden

Dahlia Del (also called Del’s Dahlias) is a small, individually run dahlia tuber nursery based in Minneapolis, Minnesota. The site was launched in 2017 under the domain delsdahlias.com, and the planting beds are spread across the Prospect Park neighbourhood and community gardens in Minneapolis and St. Paul. The online catalog is open to members only, and Del personally selects, labels and packages every tuber that ships out. Each tuber is shipped with at least one viable eye, and customers are encouraged to verify their orders on arrival and report any issue within the current growing season. The nursery does not maintain a broadcast newsletter; all updates are posted on the home page.

Membership Catalog, Pre-Sale Rounds and Tuber Guarantee

Access to the Catalog is for members only. A limited pre-sale usually opens during the winter months, with a second restock around March or April once overwintering results are clear. Member benefits include access to the tuber pre-sale, targeted special communications, personalised service, points-based rewards, and an archived Updates page reserved for members. Payments are taken through PayPal or Stripe (credit card). Minnesota residents are charged sales tax on the order total including shipping. Shipping is offered within the continental United States only and begins in mid-March, weather permitting. Trays, inserts and loaf pans are bulky and are therefore shipped only to the five-state region of Minnesota, North Dakota, South Dakota, Wisconsin and Iowa. Tubers are inspected before shipping and replaced or refunded if an eye fails to grow or a label proves incorrect.

Year-Round Workflow: Cold Storage, Cuttings and Dividing

At the end of each growing season, Del lifts every clump, trims the stems and divides the tubers before moving them into cold storage for the winter. The storage room is kept at roughly 4 to 10°C (40 to 50°F) with steady humidity so the tubers neither dry out nor rot, a temperature range commonly recommended for amateur dahlia growers as well. In early spring the tubers are brought out, potted up in cell trays with a labelled growing medium, and encouraged to push eyes; once shoots are long enough the cuttings are taken, rooted, and the parent tuber is divided into single-eye or multi-eye sections for replanting in the community beds. The Resources page on the site links to the long-form video tutorials Del recommends for taking cuttings, dividing clumps and wrapping tubers in food wrap for storage.

The Minnesota Dahlia Society, ADS and the Local Show Circuit

Del is a member of the Minnesota Dahlia Society (MDS) and the American Dahlia Society (ADS), and shows award-winning blooms at the Minnesota State Fair and at the Fall Dahlia Show held at Bachman’s, both events sponsored by MDS. Bachman’s is a long-established Twin Cities garden centre and a focal point for the local dahlia community. Any blooms that are not shown are donated to local partners such as the Our Lady of Peace hospice, Episcopal Homes (a nearby senior residence), and individuals facing difficult life circumstances; on rare occasions a few stems are sold through Soderberg’s Floral and Gift. When a variety is sold out locally, Del refers customers to Creekside Dahlias and Dahlia Addict, two independent resources that track available stock across many small growers.

Loyalty Programme, Community Outreach and Public Resources

The DahliaDel.com Loyalty Programme rewards members with one point for every US dollar spent, redeemable for discounts at checkout. The four tiers are Basic (0 points), Silver (from 250 points), Gold (from 400 points) and Platinum (from 550 points), each unlocking a different redeemable discount. The public Resources page compiles the American Dahlia Society classification, size, form and colour guides, links to Creekside Dahlias, Dahlia Addict, Dahlia University and the Dahlia wiki, and curated video tutorials on planting, taking cuttings, overwintering tubers, dividing clumps and wrapping tubers in food wrap. The site is also a member of the Minnesota Dahlia Society, so purchasers support the same growers who show at the State Fair and at Bachman’s, with surplus flowers going to hospice, senior residences and other community causes in the Twin Cities.
