If you're searching for the perfect indoor plant, you can't go wrong with an areca palm (Dypsis lutescens), which also goes by the names butterfly palm, yellow palm, or golden cane palm. Areca palms are a beautiful tropical plant that can grow up to 6 to 8 ft (1.8 to 2.4 m) tall indoors or up to 25 ft (7.6 m) tall outdoors. Since the plant is nonpoisonous, it’s a great option for homes with children and pets. As an added bonus, areca palms help clean the air in your home!With proper care, your areca palm can thrive for up to 10 years. 1. Use a well-draining, acidic soil that doesn’t clump up. Get a potting mix or outdoor soil from your local gardening store or online. Check that the soil is labeled as well-draining and acidic so your palm can thrive. Break up the soil before you plant your areca palm so you know it’ll be loose around the roots. [图片]2. Plant the palm in a well-draining pot that’s twice the size of the root ball. Choose a pot that has drainage holes in the bottom so that the plant doesn’t become water-logged. Fill the pot 2/3 of the way with potting soil. Place your root ball in the center of the pot, then cover it with more potting soil. Pat the surface of the soil gently to settle the plant but don’t pack it down around the root ball. 3. Put your areca palm in the ground only if you live in USDA zones 10 or 11. Areca palms are commonly grown as a houseplant, but you may want to grow yours outside if your area is hot and humid. Check that your region is in a USDA zone 10 or 11. If so, plant it directly in the ground if you prefer. 4. Put your areca palm in a spot where it gets bright, indirect light. Areca palms need good lighting to thrive, but direct light can hurt your plant’s fronds. Pick a spot near a window or glass door where the light filters into the room. Place your plant where it’s in an indirect beam or near direct sunlight. 5. Maintain a temperature that’s between 55 to 75 °F (13 to 24 °C). Areca palms thrive best when the daytime temperature is 65 to 75 °F (18 to 24 °C) and the nighttime temperature is around 55 °F (13 °C). For indoor areca palms, adjust your thermostat so the room temperature stays ideal. If your plant is outdoors, bring it inside on days that are very hot or very cold. Via. WikiHow [图片]

芦荟家家基本上都会养上一盆,它耐干旱易养护,而且在夏季的时候被蚊虫叮咬了,掐一个叶片来将里面的汁液涂抹到蚊虫叮咬的部位,就能够起到止痒的作用,非常的好用,养一盆芦荟放在家中,好多花友养的过程中,会发现养的芦荟越长越高,到最后就会非常的不好看,它为什么会长得高呢?应该怎么控制株型呢? [图片]芦荟长高其实只有两个原因,一品种问题,二是由于缺光所导致的。所谓的品种问题,就是我们养的芦荟是一种立木芦荟,这种芦荟家庭中最常见,它止痒的效果是最好的,它在生长的过程中不断的长高,底下的叶片会逐渐的干掉,剩下一个大的主干,有的人养的立木芦荟长到两米多高,所以说这种芦荟您不想让它长高,想让它多长侧芽多长叶片的话,要做人工的处理,怎么去处理呢?长到一定高度直接将顶部给它剪掉。剪掉以后顶部可以拿来扦插,晾干伤口放到土壤中去就能够长根,剩下的主干上它会快速的长出小的芦荟来,芦荟侧芽长得多了以后,整个挤在一起就能够达到爆盆的效果,就不会长得那么高了。再一个就是我们人为地去用药物,比如矮壮素,比如多效唑,都是可以使用的,喷一下整个植株就能够达到矮化的效果,它长势就会慢很多。 再一个就是由于光照原因所导致的,任何植物生长离不开太阳,离不开光照,所以说芦荟也是如此,如果养芦荟放到一个比较阴暗的地方去,它的叶片长得细长,长的薄而且颜色浅,我们一定要把芦荟放到太阳光最充足的地方去,芦荟不怕晒,一年四季光照越充足长势越好,植株越健壮,如果缺光的话,必然会出现徒长的情况。 [图片]芦荟非常好养,我们养它哪怕用园土栽培,都能够长得非常的好,但是在家庭中通风效果差一点,我们尽可能配置透气性好透水性好的土壤,经常把它放到太阳光底下去养护,盆土彻底干透了,直接给它浇透水,定期的补充一下多元素的肥料,就能够让我们养的芦荟长得好,叶片多,轻轻松松就能够养爆盆,如果它长高了出现徒长的情况,小齐告诉你了,按照小齐说的方法直接去处理一下,就能够达到矮化的效果,还能够出来好多好多的侧芽。

豆瓣绿叶子发软是因为室内温度较低,低于10℃,或放在窗口被冷风吹袭所致。还有一种可能,室内的温度在8~18℃之间,但此时豆瓣绿生长缓慢,浇水过多,盆土积水导致根茎生长不良。所以豆瓣绿冬季应控制温度,尽量不要放在窗边,平时注意浇水,每天向豆瓣绿叶片洒水,防止灰尘滞留。防止病害侵袭,若叶子已经发软,立即将植株移到温暖向阳处,减少浇水,等其慢慢恢复。 [图片]豆瓣绿叶子发黑的原因有:浇水不当,导致烂根;通风不良,盆土过于干燥;病虫害侵袭。 在豆瓣绿的养护中注意正确浇水,做到见干见湿,经常通风,将植株放在阳台向阳处,但要避免阳光直射。每年春季进行换盆换土,不然土中的养分消耗殆尽,豆瓣绿会烂根,不过在上盆之前,要用清水冲洗根部。 若豆瓣绿叶子变黑,并且持续恶化,有可能是病虫害的原因,在不影响观赏价值的前提下,将发黑的叶子剪掉,然后喷洒药剂进行防治。 [图片]豆瓣绿的养殖经验: 豆瓣绿要求土壤腐殖质丰富、疏松、肥沃、排水良好。可以选择叶土7份、河沙3份,加少量基肥配成培养土,或者用泥炭土6份、珍珠岩4份及少量基肥混合配制。种植时一般直接购买盆栽,不需要配土,大家对土壤的成分稍有了解即可。 豆瓣绿性喜温暖、湿润、半阴的环境,耐高温,生长适温为25℃左右,冬季在10~15℃可以正常生长,10℃以下停止生长,5℃以下受害,低于0℃会受冻死亡。 豆瓣绿较耐阴,四季均可放室内有明亮散射光处培养。春秋季可多见些光,冬季放朝南窗沿附近多见阳光,夏季放朝北窗台,适当遮光。光线适宜时叶色艳丽,光线太强或太暗都会使叶色失去娇艳色彩。 豆瓣绿浇水要盆土干湿相宜,生长过程中,春秋是生长发育旺季,水量多些。夏季天气炎热但植株因温度高其生长反而缓慢,可早晨或傍晚各浇1次,高温多湿茎叶易烂,具体看天气及盆土而定。盆土应略偏干一些,因其茎叶肉质肥厚,过湿易使根部腐烂,特别是冬季因气温低,呈休眠状态,盆土宜带干。 豆瓣绿通常2~3年更新1次培养土。生长期间,每隔15~20天追施1次腐熟液肥或氮磷化肥,浓度为饼肥15%~20%,氮磷复合肥0.2%~0.3%。若施肥不知分寸,可减少氮肥,可使叶片上的斑纹更加显著。

雏菊又被人称之为码头兰花、太阳菊等等。雏菊是一种属于菊花类植物,它是常年生长的花草。雏菊最早的原产地是来至欧洲,也被意大利人推举为国花。最早的时候被人认为是杂草,后来开花后被人发现,它的花朵是具有一种君子的风度,非常的好看。雏菊的花枝能长到十厘米左右,花枝部分是单生的,花朵的直径有三厘米左右,花期是在入春后,在寒冷和炎夏的季节均能生长。下面我带大家了解一下雏菊的种植方法与养护妙招。 [图片]生长习性 雏菊喜欢凉爽的气候,非常惧怕炎热的季节,喜欢在阳光充足的地方成长。雏菊对于泥土的要求不是特别的苛刻,最适合种植发芽的温度是在二十二至二十八度之间,最适合成长的温度是在二十至二十五度之间。西、南地区是最适合种植小花瓣或者是中型花瓣的品种,大花瓣的品种不适合在以上两个地区种植,会使植物的成长较慢,开出的花朵也是非常难看的。 种植方法 在种植雏菊的时候我们都知道它的种子很小,每颗的种子里面有五千多粒基本上都是在九月份的时候给它进行播种,在播种以后要把它的温度保持在二十度湿润度要保持在百分之八十,大概在一个多星期左右的时候就会长出新的根芽,在种子发芽以后还要保持土壤的湿润度,在这个时候不需要给它喷肥,要记得把它拿到室外给它充足的阳光,在发芽的时候不可以在太阳下面直接照射,要保持适当的遮阳,在八月份的时候还要把它拿到室内,在它生长稳定以后就可以给它移栽了。 移栽上盆 在种子出苗之后当它的小苗有三片叶子的时候就可以给它移盆了,在一个花盆里面移栽到2棵到3棵,在移栽好之后就可以长期的不用给它换盆了,在给它移栽的时候,我们可以适量的给它添加一些有机肥,但是在添加有机肥的时候要给它兑点水,因为雏菊不喜欢浓肥就可以选择给它兑点水稀释一下,在刚移栽到花盆中的时候要记得把水浇透。 [图片]温度需求 在移栽好之后要把它拿到室内过冬,在冬天的时候可以把雏菊的上面套一个塑料带这样是可以更好的防止冬季的温度过低引起的冻伤,基本上在冬季的时候温度有六度以上就可以安全的过冬,如果条件可以的话,可以把它的温度保持在二十度,这样对于株形的形成是最好的,在基本的情况下是很难做到的,当温度在二十度的时候雏菊都是可以正常的开花的,在温度低于九度以下的时候它的生长速度就会减慢还会影响它开花的时间,当温度高于二十四度的时候雏菊的花茎就会长的比平时长一些也会减少它开花的量,在七月份左右的时候就要给它拿到室内降温,反之的话就会影响雏菊的正常生长。 水肥管理 雏菊是喜欢在比较有营养的土壤环境中生长的,单单的去靠它刚配制出来的土壤是不可以满足雏菊生长的要求,因此要在一个星期的时候就要进行添加一次营养,在给它添加营养液的时候,不可以一次性的给它添加过多,要给它浇水量相比就是要添加百分之一,在它生长出花蕾的时候也要及时的给它补充营养,这个时候就要三天给它添加一次营养液,这样可以促进它开出的花更加的大,颜色也更加鲜艳,在它生长速度比较快的时候也要及时的给它添加营养,这样的话可以让雏菊的枝叶长得更茂盛同时还起到的了花开的时间。

1. Choose houseplants suited for your available light conditions. The first step in preventing insects actually arises when you choose your plants. Make sure each houseplant is well suited to the amount of light it will receive once in position. Plants in unfavorable light conditions are subjected to stress, which makes them more susceptible to insect infestation. 2. Make sure your houseplants are potted in sterile soil. While bacteria, fungus, and insects are a vital component of outdoor soil health, houseplants are better planted in store bought potting mix, which will generally be sterile. Using outdoor garden soil can introduce insect larvae into your houseplants. 3. Clean your houseplants regularly. Dust buildup on your houseplant leaves often contains organic compounds (like skin cells or pet hair) that insects can feed on. Furthermore, insects like mites thrive in thick layers of dust and will be less likely to infest a clean plant. [图片]4. Inspect your plants regularly for insect damage. This may sound obvious, but in fact most insect infestations can be mitigated if you are monitoring your houseplants closely enough to catch the early signs. Discolored, speckled, mottled, and chewed up leaves can indicate insect activity. Of course, you may also be able to see the insects themselves as well as their eggs, larvae, or cast off skins. 5. Control existing insect infestations as well as possible. Even if you take the precautionary steps above, you may still find yourself faced with insects in your houseplants. There are several method you can use to kill and remove insects. *Sticky traps can be used to control infestations of flying insects such as fruit flies, gnats, and winged aphids. These traps are usually yellow in appearance and can be hung near the infested houseplant. *Pruning can help control isolated insect infestations. If you notice that most of the insects are concentrated on a few leaves of a plant, prune these leaves away and throw them out. *Wash small insects away with soapy water. Small insects like aphids and mealybugs can be removed by rubbing the plant's leaves with a cloth moistened with soapy water. [图片]6. Know when to give up on an infested houseplant. The unfortunate truth is that when a houseplant becomes badly infested with insects, it is near impossible to remove the insects and return the plant to health. In bad cases, throw the entire plant away before the insects spread to other houseplants in your home.via wikihow

金手指是多肉植物仙人掌的一种,因为它形似人的手指头,而且叶片上带有金黄色的刺,外形十分美观迷人,颇受一些多肉控们的喜爱,有些养花新手也会入手,那么,金手指是怎么发根的呢,当它爆盆的时候,怎么给它分株盆栽呢?今天小花匠就来说说金手指的发根和分株问题。 [图片]爆盆的金手指盆栽 问题1:金手指怎么发根? 金手指可以切下一小段进行繁殖,只要生根后就能成活,就是要注意,金手指切下来的时候伤口不能沾水,最好是放在阳光晒不到的地方阴凉处,伤口愈合晾干后在进行扦插,这样入土后就不会因伤口沾到水而腐烂,摆放在阴凉的地方养护,尽量少浇水,大概两三星期它就会生根了,不过,这个时候的根系还十分细弱,不耐水,所以,不耐频繁浇水,只要在盆土表层发白,干了之后再沿着花盆边缘浇水。 金手指切段可以扦插繁殖 金手指根部腐烂的时候,只要上面部分还是绿的,那就可以切下来重新盆栽,注意,切断的位置一定要离根茎腐烂部分远远的,不能带有黄色腐烂物质,避免细菌感染,或者就算伤口干了也插不活,还是会继续烂掉的。 烂根的金手指腐烂部位一定要切除 问题2:金手指怎么分株盆栽? 金手指容易长出子株,只要养护得好,很快就会爆盆,这个时候密密麻麻的会影响它的生长,只能换个大的花盆,或者分株繁殖,那么,怎么分株呢? [图片]爆盆的金手指应适当分株 分株方法:将母株从盆土里挖出,去掉附着在根部的泥土,然后根据金手指的茎干和根系结构,顺着它自然生长的部分,借助一些工具将其掰开(有刺,不要用手直接掰),注意别折损了茎干,断成一小段一小段的就不好看了,根茎过于密集,就用刀劈或用剪刀将它们剪开,伤口不要太,以免影响愈合,待伤口愈合后就可以上盆了。 单株的金手指很快就能长出分株 若是金手指分株很多,那就要多备几个花盆,给金手指留足生长空间,这样有利于新株生长。

Hi, everybody, today let's learn something about how to grow onions! 1. Choose a type of onion to grow. As with most fruits and vegetables, there are many variations of the onion that are appealing for different reasons. Onions come in three general colors - white, yellow, and red/purple - each with their own distinct taste. Additionally, onions are categorized into two growing types: long-day and short-day. Long-day onions are named such because they begin sprouting when the days between 14 to 16 hours in length (late spring/summer), while short-day onions begin sprouting when days are between 10 to 12 hours in length (winter/early spring). 2. Decide how you will plant the onions. In general, there are two popular ways of growing onions: using either onion sets (bulbs) or using onion seeds. Gardeners tend to prefer planting onion sets, as they are a bit hardier and stand up to poor weather better than onion seeds. However, if you're able and willing to grow your onions from seeds indoors and transplant them outdoors, you can certainly raise them all on your own from seeds. You can also plant your onions in the ground in warm weather. 3. Know when to grow. Onions can be tricky to grow if they're not planted at the right time. If planted in cold weather, they can die off or waste energy in blossoms rather than bulbs in the spring. If you're planting seeds, start them indoors at least 6 weeks prior to planting outdoors. Make sure that you sow the onions 6 weeks before your average last frost date, and set them out after that date. 4. Select the ideal location. Onions aren't too terribly picky when it comes to growing conditions, but they do have some preferences. Select a place with plenty of room and full sunlight. Onions will grow quite large if they're given enough space, so keep in mind that the more area you give them to grow, the larger they will get. Avoid planting them in a location that is shaded by larger plants or trees. [图片]5. Prepare the soil. Although it takes some forethought, if you are able to prepare the soil of your plot for planting several months in advance, you'll receive a better onion crop down the line. If you're able, begin tilling the soil and adding in manure in the fall. If your soil is very rocky, sandy, or has lots of clay, mix in some potting soil to help even things out. Additionally, test the pH level of your soil and add in any necessary compounds in order to create a pH that falls between 6 to 7.5. 6. Get the soil ready. When you're ready to plant, till the soil about 6 inches (15.2 cm) deep and add a layer (1 cup per 20 feet) of phosphorous fertilizer. However, only do this if your soil is low on phosphorus. Be sure to test your soil first to find out. Using a mixture such as 10-20-10 or 0-20-0 will provide an extra boost for your developing onions. At this point, be sure to remove any weeds that may be present in the garden plot you're planting in. 7. Dig the holes. Plant onions so that no more than one inch of soil is placed above the sets or seedlings; if too much of the bulb is buried, the growth of the onion will be reduced and constricted. Space onion sets 4–6 inches (10.2–15.2 cm) apart, and onion seeds 1–2 inches (2.5–5.1 cm) apart. As your onions begin to grow, you can transplant them and space them further apart in order to increase their growing size. 8. Plant the onions. Place your seeds in the holes you've dug, covering them with ¼ to ½ inch of soil. The sets should be no more than two inches deep. Use your hands or shoes to firmly tamp the soil over the top of the onions; they grow better in firm, rather than loose, soil. Finish up planting by adding a bit of water, and you're set to watch them grow! via.wikihow [图片]
