Ranunculus is a large genus of about 600 species of plants in the Ranunculaceae. Members of the genus include the Buttercups, Spearworts, and Water Crowfoots.[图片]They produce cheery multi-petaled flowers. The almost unpronounceable name covers a large group of perennials from Asia and Europe. The plants aren’t very hardy and may be annual in colder zones. They are easily damaged by temperatures below 28°F (-2°C), and thrive best in USDA zones 8 to 10.[图片]A colorful field of flowers livens up the landscape and is easy to achieve with Ranunculus plants. Ranunculus bulbs come in several sizes and are best planted 4 inches (10 cm) apart. Using Ranunculus for the garden will reward the grower with an abundance of color and texture from early spring into the first month of summer. Ranunculus for the garden come in an array of colors from white, red and gold to orange, yellow and pink. The flowers boast layers of petals and will develop up to 12 inches (30 cm) in height. You can choose standard sized Ranunculus plants or dwarf specimens, which only get 8 inches (20 cm) high. Some varieties will produce flowers that span 6 to 12 inches (15 to 30 cm) in width. You may start Ranunculus bulbs directly outdoors or purchase started transplants at a nursery. The tubers must be soaked prior to planting for best results. Use the plants in borders, containers and wildflower fields. The thick rosettes will last for a week or more when used as cut flowers. Plant bulbs outside in fall in warmer zones and start them indoors in pots in cooler climates.[图片]Growing Conditions and General Care Growing Ranunculus flowers starts with planted roots or tubers. Often called Ranunculus bulbs, tubers are different but have similar structures and purposes to the more common bulb. Plant the bulbs or tubers in fall for a glorious spring display. Growing Ranunculus flowers requires well-drained soil and full sun for best results. Soak the tubers and then plant then with the roots or fingers pointed downward at a depth of 1 to 2 inches (2.5 to 5 cm), depending on the size of the bulbs.[图片]It is an easy flower to grow. Care of Ranunculus to ensure yearly displays may require that you pull out the tubers at the end of the season. Allow the foliage to almost completely die back and then dig out the tubers. Lay them in a cool, dry place to evaporate all the moisture from the bulbs. Store the tubers in a dark location until spring and then start them indoors in pots. Replant outside when all danger of frost is passed and the first true leaves are evident.[图片]Plants require temperatures of no more than 60 F. (16 C.) during the day and 45 to 50 °F (7 to 10 °C) at night to break dormancy and begin sprouting. Plants may survive as perennials in Zone 7 if you mulch lightly around the bases. Follow these suggestions when growing Ranunculus flowers for garden displays or cut flowers and you will reap the rewards year after year.

我说肉肉你说萌！

2017年09月28日

一般来说选用的盆，要比多肉的冠幅（直径），大个1-2cm，或1/3-1/4，更利于多肉长大，或群生。盆的高度可比盆宽度略高，或略矮（瓦苇系的盆可高点），通常不建议细筒高盆，不利于空气流通，也不利于把握浇水的分量。 #多肉种下后，盆留有一定间隙，方便多肉生长，也方便自己浇水。 [图片][图片][图片][图片][图片][图片]如果植株本身是生长较快的品种，如仙女之舞、玉蝶，选择的盆可以再大点，如植株的2-3倍宽，盆太大，浇水的时机会较难把握。不清楚长得快不快，则参考上一点，可以等长大了，再换盆。盆过大的情况下，浇水要多用点心。 [图片][图片]如果，不想多肉长太大，保持多肉娇小的体型，则可以用跟多肉大小差不多，或比多肉还小的盆，以达到控型的目的。已经半木质化的老桩也没必要换更大的盆，已经长不动了。 [图片][图片]

弄啥嘞

[图片]#雏菊能是否适合水培估计问出这个问题的网友们也是因为买来的鲜切花觉得丢弃太可惜了，所以想着看看能否在花瓶里进行水培，让雏菊存活下来，小编可以告诉大家这不是一件只要按步骤操作了就能成功的事情，因为雏菊是一种土壤栽培的花卉，水培对它来说并不是一种合适的栽培方法，不过大家可以试一下。 [图片]雏菊水培的方法如果大家手头上有新鲜的雏菊花束就需要先进性一下消毒处理，因为无论是任何植物想要在水中栽培都要进行这个操作，这是防止细菌滋生的最佳做法。其次要将准备好的花瓶灌上水，不要太满，大概在70%左右即可，然后将收拾好的雏菊枝条放进去，滴上适量的水培夜，然后放置在一个比较阴凉但不晦暗的室内环境，要注意通风效果良好。水培最关键的就是水分的干净，长时间不换水会导致枝茎底部腐烂，滋生细菌影响植株健康，所以大家还要注意及时换水。一般的情况下雏菊在水中栽培能够存活两到三周的时间，如果超过三周还没有丝毫要萌发新根的迹象，基本上就能判定水培失败了，所以小编不能明确的告诉大家是否可以水培，只能建议大家自行去尝试一番，或许你就可以成功。 [图片]

If you want your neighbors to think you’re an award-winning gardener, try planting dahlias in your garden this year. Just when everything else starts to show the strain of midsummer, Dahlias begin a showstopping performance that lasts through fall. Dahlias need just a little bit of special care in some climates, but the rewards far outweigh the work.[图片]About Dahlias Buying: Dahlias are sold as tubers, but they may also be available planted in pots at garden centers in the spring. For the most interesting selection, visit your nearest Dahlia society. Cold Hardiness: Dahlias are considered true perennials only in zones 6-7 and warmer. In cooler climates, they can be treated like annuals, or you can dig up and store the tubers over the winter. Cold hardiness for Dahlias depends on the variety, so check the label when buying. Size: Dahlias range from foot tall dwarf varieties to towering 8 feet (2.4 m) giants. Quality: Look for plump, firm tubers with no spoiled spots and at least one eye. Unlike potatoes, Dahlia tubers have eyes only on the top, where the stem meets the root.[图片]Growing Conditions Light: Full sun 6-8 hours a day is ideal, although if you live in a hot climate you may want to give them a little cooling afternoon shade. Soil: Loose, fertile, well-draining, slightly acidic soil. Dahlias put out tiny feeder roots that require light soil that holds moisture without being soggy. Clay soil should be amended with compost, sand, and/or humus. Water: Dahlias need regular water but will rot in heavy wet soil. Fertilizer: Dahlias need lots of nutrients, especially when blooming. Rich soil and balanced organic fertilizer will help. Cautions: Dahlias are very susceptible to rot and freeze, so keep this in mind when choosing your planting site.[图片]How to Plant When to Plant: Plant Dahlias in spring, after all danger of frost has passed. If the weather has been soggy, wait until the soil dries out a little. Soil Preparation: Till the soil about a foot deep. Work in plenty of well-rotted compost, sand, or humus. Avoid manure or fresh compost – it’s too high in nitrogen. If you’re buying soil, make sure it hasn’t been treated with weed preventers since Dahlias are very susceptible to herbicides. Planting: Plant Dahlia tubers about 2 feet (60 cm) apart and 6 inches (15 cm) deep, with the eyes facing up. Watering: Ideally, you shouldn’t water new Dahlias, but let the spring rains work their magic. If it’s already hot and dry, you can give them a light watering.[图片]Support: Taller varieties need stakes for support. Install a bamboo stake or tomato cage when planting, so that you don’t cause damage later. Identify: Tag plants with the name of the variety to prevent confusion if you dig them up to keep over the winter. Mulch: Add a couple of inches of mulch to hold in moisture. Growing Tips Fertilizing: Feed Dahlias about once a month with an organic fertilizer lower in nitrogen and higher in phosphorus and potassium, such as a 1-2-2 ratio. With enough compost, your Dahlias will do fine without fertilizer. Watering: Make sure your Dahlias get an inch of water per week. Keep track of rainfall so that the water is consistent. Deadheading: Clip off spent blossoms to encourage more blooming. Disbudding: While optional, some gardeners remove many of the flower buds to focus the plant’s energy on fewer, larger and showier blooms with long stems. The flower buds come in clusters of three. If desired, remove the two side buds and allow the middle one to grow, and keep pinching off any more side buds that form along the end of the stem.[图片]Pinching: For a more natural look, pinch back Dahlia plants when small to encourage branching. Dividing: Dahlias can be divided in fall or spring. Dig up the tubers and use a sharp knife to cut into sections, making sure each section has at least one eye. Allow tubers to dry overnight before replanting. Overwintering Outdoors: If Dahlias are hardy in your zone, simply cut them back after the first heavy frost and apply an extra layer of mulch to protect them from the cold. Remove the extra mulch in spring.[图片]Overwintering Indoors: In colder climates, dig up and store the tubers in a basement or garage, then divide and replant them in the spring. Weeding: Hand pull weeds around Dahlias, or smother with mulch. Don’t use any sprays. Cut Flowers: Dahlias make stunning bouquets! Cut the blooms in early morning for best results.

Para ello, te damos un pequeño instructivo que te será de mucha utilidad PASO 1 Primero, debemos seleccionar las plantas de exigencias de cultivo similares. Después, humedeceremos la tierra de los tiestos. Montaremos el grupo decorativo colocándo los tiestos en el contenedor, situando las plantas más elevadas en la zona posterior. PASO 2 Una vez que tengamos bien planificado cómo vamos a desarrollar el conjunto, prepararemos el contenedor colocando una capa de 5 cm de drenaje (gravilla o trozos de tiesto) en la base y, a continuación, la cubriremos con una capa de tierra: mezcla de 1 parte de arena y 3 de emzcla para tiestos de tierra negra. PASO 3 Seguidamente, retiraremos las plantas de los tiestos, con cuidado de no pincharnos (dado a que la amyoría de los cactus tienen espinas agudas, al movelos, es aconsejable usar guantes), y las colocaremos en el contenedor, rellenándolo despues con tierra. Debemos tener precaución de dejar el suficiente espacio entre una y otra planta para que puedan desarrollarse. PASO 4 Finalmente, revestiremos el contenedor ya plantado con una capa de 5 cm de gravilla. Para crear un aspecto aún más natural, podemos añadir piedras decorativas.

[图片]育苗选取 #香瓜种子以后，先把它晒两天。然后再用55度的温水一遍倒水一遍搅拌后泡上5到8个小时即可。将种子取出洗净以后再用湿的棉毛巾包好套一个塑料袋，放到30到32度的环境中，一般18到20个小时后芽就能出来了。等到长出了四片叶子的时候就能定植了。 [图片]管理在植物的苗期，除了花打顶以外等枝杈长到3到5cm时再将杈打掉，最好是在天气比较好的上午，不能用剪刀或是手掐。浇水的话要在长出2片叶子再浇，第一次的时候不需要施肥。等到第一茬瓜鸡蛋大时再用膨瓜肥。一般10到15天浇一次水就可以了。施肥幼苗期的时候，一般施氮磷含量都比较多的。茎叶生长较快的时期主要用氮肥。结瓜的时候主要施用钾氮肥。授粉如果需要手动授粉就要在上午进行，建议在9到10点之间，应该在雌花开后的两小时授粉。采收等到香瓜成熟了之后就可以采收了，具体方法是用手指按靠近果脐的那一面，发软就是熟了，或者是闻一下有么有香瓜所独有的浓香，如果熟了的话就用剪刀剪下来。 [图片]
