在种植前吞噬甜豌豆种子。

由于柔软而香,因为他们的绽放可能是,甜豌豆种子有臭名昭着的坚硬的外观。加快萌发过程迈尔斯建议在种植前仔细地造成仔细吞噬每种种子(这涉及削弱种子涂层)。“你可以通过使用指甲锉或砂纸来轻轻划伤种子外套来完成此操作,”她解释道。你也可以将甜豌豆种子浸泡在水中约8个小时,帮助软化他们的“壳牌”。“过夜浸湿湿纸巾的种子,第二天他们应该准备好植物,”戈弗雷说。

Once your sweet pea种子被淹没了,Myers说,将它们植入户外斑点,每天至少接受六个小时的直射阳光以获得最佳的开花。“如果您的气候更热,请提供一些下午的阴影来帮助延长绽放时间,”她建议。种植甜豌豆种子时,戈弗雷说,他们应该播种约一英寸深,间隔三到四英寸,以确保他们有足够的空间来增长。“富裕的植物富裕,土壤良好,”他补充道。“如果土壤过湿或干燥,甜豌豆就不会表现良好。”

在较冷的气候中启动他们。

如果你住在一个较冷的气候,那里的地面往往冻结,迈尔斯说你可以开始甜豌豆冬天在室内的种子。"Sweet peas can be started indoors up to six to eight weeks before the last spring frost, and then transported outdoors in early spring," she explains. "Just remember to space the seeds at least two-inches apart, or twine each plant as they grow, so they're easy to separate when it's time to move them outside."

为生长甜豌豆提供支持。

由于大多数甜蜜的豌豆正在攀登葡萄藤,因此戈弗雷说他们经常需要支持来增长。“当用网状物和麻线的篱笆支撑时,植物将掌握并保持其卷须(这就像微小的绳索),”他解释道。为了避免损害你不断增长的甜豌豆植物的根源,Myers建议安装一个格子或类似的staking systemprior to planting seeds or transplants. "This will make it easier to direct young plants up the support as they grow—instead of forcing them to climb—so they can climb with minimal interference," she explains.

Mulch matters.

甜蜜的豌豆是厚重的饲养者,这就是为什么戈弗雷说他们会在被修改的土壤中成长很多堆肥。如果添加堆肥不是一个选择,“施肥就会产生很大的不同”,“他说。“粒状时间释放的肥料是最简单的,因为它们可以持续数月,但可以每周给予稀释的液体肥料。”Godfrey建议使用肥料含量高于氮的肥料,以帮助提高花卉生产。“太多的氮气会刺激植物到达星星而不是创造恒星花,”他解释道。
