Sort the seeds by requirements, and only sow those kinds with the appropriate conditions. Sow the hot summer types together, sow the cool winter types together apart from the summer types.
The soil mix is very controversial. I like a combination of native loam soil at about 80% mixed with 20% sphagnum. Add some grit if desired.
I prefer sowing 1 kind per 1 pot, and not to sow many kinds in a common flat, as they can have very different watering and temperature needs.
Scatter the seeds on your soil surface, and then sprinkle a tiny bit more soil over the seeds to barely cover them. Then over this I like to cover the top surface with a thin layer of sandblasting grit. The grit we use is about 1 mm in diameter and I prefer to use a dark opaque color.
Put the pots into a shallow box for germination. You can use spare household equipment from the kitchen or build some from wood. I put side walls about 8 inches high on a sheet of plywood. Over this box I like to cover it with nylon window screen that is available at most lumber or hardware stores. During germination the cover remains on the box, you can mist through the screen and light and air passes readily. For the first several days you can mist several times daily to keep the pots moist. After a week the number of times to mist can be reduced to once or twice daily. Once the pots start to sprout you can remove them from this area and place them where there is not as much misting or humidity.
You can put the box in your greenhouse, or on a sunny windowsill area, or indoors under lights. I do a lot of germination with the boxes outdoors under a layer of shade cloth. The natural sunlight and heating is wonderful, and rainfall is the best germinator of all. Naturally if heavy rain is expected precautions will need to be taken. Make sure your box has plenty of drain holes so water can not pond.
The above methods are fine for Sclerocactus and Pediocactus with a few changes. These seeds need a long period of exposure to freezing and thawing conditions. Nothing has improved upon sowing the pots outdoors during the winter in a temperate climate. I try to get the seeds sown by mid January. They just go outdoors in a box exposed fully to snow, cold winds, and everything else that happens in the winter. It does get cold here in the winter and we can have 2 or 3 feet of snow. Quite a few nights fall to between 0F and 10F with a few nights below zero F. Then in early spring I start to water them daily. It is still freezing a bit at night and warming up in the day to 50 to 60F. Water them daily all spring, they are really quite thirsty at this time. During the heat of summer water less, just give an occasional heavy soaking. Most germination takes place in the spring or early summer. In the fall cool and dry.
Summary for Pediocactus, Sclerocactus and Toumeya
Winter: freezing at night, cold in the day, mostly dry, under sow is great.
Spring: cool and very damp, daily waterings.
Summer: occasional heavy soaking, mostly dry.
Fall: cool, occasional light water, mostly dry.

排序的种子被要求，只有母猪这些类型与相应的条件。母猪在炎热的夏天类型在一起，母猪凉爽的冬季类型在一起除了夏天的类型。
土壤结构是非常有争议的。我喜欢天然沃土约80％与20％泥炭混合的组合。添加一些砂砾如果需要的话。
我更喜欢播1种每1锅，而不是播种多种在一个共同的平坦，因为它们可以有非常不同的浇水和温度的需求。
散布在你的土壤表面的种子，然后撒上一点点更多的土壤比种子勉强遮盖。然后在此我想盖顶表面有一层薄薄的喷砂砂粒。我们使用的砂砾为约1毫米，直径我更喜欢使用一个深色不透明颜色。
把锅入发芽浅水中。您可以用备用家庭设备用品从厨房或建立一些木材。我把侧壁高胶合板的片约8英寸。在这个盒子我喜欢用尼龙纱窗是可在大多数木材或五金商店覆盖。在发芽的封面仍然在包装盒上，你可以通过屏幕和淡淡的雾气和空气通过爽快。对于前几天，你可以每天薄雾数次，保持盆湿润。一个星期后，多次以雾的数量可以每日一次或两次减少到。一旦盆开始发芽了，你可以从该区域中删除，并把他们那里有没有那么多雾或湿度。
你可以把盒子里的温室，或在阳光明媚的窗台面积，或在室内灯光下。我做了很多的萌发与箱子的户外下一层遮光布。在自然的阳光和暖气是美好的，而雨量所有最好的发芽器。当然，如果大雨预计的预防措施，将需要采取。请确保您的箱子有大量的排水孔使水不能池塘。
上述方法很适合Sclerocactus和Pediocactus了一些小改动。这些种子需要暴露于冷冻和解冻的条件的一个长的时期。在冬季气候温和期间播种的花盆户外一切都没有改善。我试图让明年1月中旬播下了种子。他们只是去户外在一个盒子里充分暴露雪，冷风一吹，那发生在冬天的一切。它变冷这里的冬天，我们可以有2个或3英尺的雪。不少晚上下降到0F和10F之间，低于零F.了几晚。然后在早春，我开始每天浇水。它仍冻结位在夜间和白天升温至50〜60F。日供水它们春天，他们真的很口渴，在这个时候。在夏季，水少的热量，只要给一个偶然的重浸泡。大多数发芽发生在春季或初夏。到了秋天凉爽和干燥。
对于Pediocactus，Sclerocactus和Toumeya摘要
冬季：冻结夜晚，寒冷的日子，大多干燥，在母猪是伟大的。
春季：酷，非常潮湿，每天浇水。
夏季：偶尔重浸泡，大多干燥。
秋季：凉，偶有轻水，大多干燥。 |
