现在多肉养殖越来越流行，但是生命有时也是很娇贵的，多肉会出现各种问题，其中一种就是化水，作为一个养殖多肉了两年多的小编，小编在这里就和大家聊一聊关于多肉化水的问题，告诉大家化水的拯救方法，希望对大家有帮助。
化水的原因多种多样，但最常见的就是持续闷热潮湿的环境，一般前期肉肉表现出来就是叶片开始化水掉落，或者掉落后就化水，化水的叶片通常呈透明状,严重的话会出现黑腐的现象，就是茎部是黑色的，摸上去是软烂的感觉（有的老的桩由于养的比较久也会呈现深色，但是摸上去是硬的，是没事的）。　　 通俗来讲，黑腐是化水的严重化了，所以我们可以分开看 1、多肉化水的植物，如果只是底层叶片个别化水的，情况不严重的，可以直接摘除化水的叶片，并且加强通风，如果盆土非常湿的话可以拿出来晾干后再干土上盆，日照的话就适当减弱缓缓盆，植物恢复正常后再加强日照正常养护就可以了。 2、如何整体已经化水比较严重了，并且伴随掉叶的现象，这个时候最好是拿出来清理根系，并且检查是否有黑腐的现象，有黑腐的话需要及时砍头，整体喷洒多菌灵稀释液后再充分晾干，干土上盆，明亮处缓盆。、已经出现黑腐的植物，需要拿出来及时的用利器切除所有黑色部位，喷洒多菌灵后充分晾干再干土上盆，有时候整桩砍成单头也是没有办法的事情。
看完如何处理黑腐化水的肉肉，我们看看平时养护的时候怎么尽量避免发生这样的情况。 首先还是要保证一个良好的通风环境，土壤见干才浇，盆土尽量保持干燥，平时季节偶尔淋淋雨什么的都是可以的，但是六七月以后天气逐渐转热，这时候淋场雨或者浇透水，刚好又赶上闷热的阴雨天，就会比较麻烦，所以温度高的时候还是尽量减少浇水比较好。 同时，上盆的时候土壤混合多菌灵粉末也可以起到一定的杀菌预防作用。配土的时候，土壤颗粒比例最好不低于50%，这样可以保持比较好的透气性及排水性。铺面的时候尽量也采用透气性好的颗粒土，如赤玉土、麦饭石等，个别肉友喜欢用那种白色的石子或者彩色的石子（其实是染色的）铺面，其实是不透气的，是不推荐使用的。

植物冻伤应该是冬季常发生的事，今天我们来说一说多肉被冻伤后怎么办。冻伤的程度不一样，处理的方法也不一样。
1.轻微冻伤 多肉植物部分叶片出现被冻伤的痕迹，明显的特征就是就是叶片出现水化瘪缩的征兆，变得透明化，甚至是灰化，像这种只是部分叶片出现冻伤的，可以放到之内供温，只要接下来的养护环境不要再趋于0℃（最好10℃以上），多肉植物活下来没什么问题，被冻伤的叶片则无法恢复，早晚瘪缩水化掉下来。
2.严重冻伤 多肉植物整株大部分叶片甚至就茎干都出现被冻伤的痕迹，明显的水化瘪缩，变得透明化甚至灰化黑化，像这种情况就比较复杂，如果只是叶片出现出现冻伤痕迹而茎干没有透明化黑化，那么将多肉植物放置在10℃以上，明亮且略通风的环境一周左右，期间不要浇水，将明显冻伤的叶片去除掉，略作观察。如果没有水化的趋势，一般都可以继续坚强的活下来。如果茎干有透明化软化的迹象，将冻伤的茎干部位切除干净（一定要切除干净，没切除干净会一直蔓延上去），伤口涂抹多菌灵，再放置观察，等一段时间后再枝插。如果部分茎干一开始就已经有冻伤的痕迹，那就直接将冻伤的部分切除掉，然后重复上述步骤。 3.被冻死了 如果多肉植物整株叶片全部严重冻伤，连茎干都水化了，那就只能安息了。

多肉灯泡是隶属于番杏科肉锥花属的多肉植物。表皮通常呈亮绿色，半透明，夏季休眠，光照充足的环境中表皮呈红色。花淡紫红色，中心白色，春季或秋季开放。花通常在天气晴朗的白天开放，夜晚闭合，若栽培环境光照不足或阴雨天则难以开花。半透明状在直射光下可以看出它是半透明的，闪着微微发红的光泽因植株晶莹剔透，看上去亮晶晶的，酷似灯泡而得名，又因株型很像日本的富士山，故有“富士山”别称。
下面要给大家分享的是灯泡多肉的常见三种病害及其防治方法。 1、粉虱危害 在叶背刺吸汁液，导致灯泡萎蔫，同时诱发煤污病，灯泡不再晶莹剔透，直接影响植株的观赏价值。 防治方法 加强通风，降低空气湿度。发生初期可用40%氧化乐果乳油1000-2000倍液喷杀，还可用马拉松500倍液或乐果混敌敌畏1000倍液喷杀，喷药2天后再用强力水流将死虫连同黑粉一起冲刷掉。 （注意：粉虱抗药性较强，较难杀灭，喷洒药剂要连续，并且经常换药。） 2、介壳虫危害 吸汁液，导致植株生长不良，严重时出现枯萎死亡。灯泡顶端出现许多白色的絮状物，后期成片出现。 防治方法 数量少时，可用毛刷驱除、牙签戳。也可用速扑杀（介必治、护花神均可）稀释液喷杀（有粉慎用），灌根、洗根。用75%酒精在介壳虫集中部位多次刷除。 3、小黑飞危害 喜欢腐殖质的食物，通常在肉肉旁边乱飞，啃食液肉，使其伤口感染产生病害。 防治方法 成年的小黑飞，喜欢湿怕干，在洋荤中保持土壤相对干燥，不给成虫创造栖息环境。养护中注意通风，保持盆土表面的清洁，不要什么都当做肥料放入盆中，科学施肥才是正道。在盆土表面铺上一层蛭石或者河沙，不要将腐殖土露在外面。
日常养护注意事项 灯泡喜凉爽、干燥和阳光充足的环境，适宜在昼夜温差较大的条件下生长，不耐阴、耐干旱、怕积水，既不耐寒，也不耐酷热。 9月至翌年4月至5月间为植株的生长期，可放在阳光充足处养护，避免水大，否则植株表皮易裂，看上去破败不堪，严重影响观赏，如果长期积水，还会造成植株腐烂。 由于灯泡生长速度不是很快，对养分的要求不是太高，栽培中不必施肥。 冬季置于室内阳光充足之处，不低于5℃即可安全越冬。 夏季的休眠期，要求有良好的通风环境，并避免烈日暴晒，控制浇水，使那层“牛皮纸”样的老皮中的水分蒸发、变薄，紧贴在植株上。 栽培中无论什么时候都要避免雨淋，尤其是长期雨淋。 灯泡的换盆在秋季进行，盆土要求疏松透气，排水性良好，具有一定的颗粒度，含有适量的石灰质，由于土壤是湿润的，栽后不必浇水，等1至2天后浇一次水，以使根部与土壤结合紧密。

山地玫瑰之所以受众人喜爱很大原因是因其休眠期为躲避强光、酷热等不利气候，外围叶子老化枯萎，而中心部分的叶片紧紧包裹在一起，株型酷似一朵朵含苞欲放的玫瑰花。山地玫瑰生长在峡谷、山地的岩石缝隙里、针叶林地。休眠期7月至8月。休眠期间外围叶子枯萎，中心叶片紧缩呈玫瑰花形，夏季通风、少水、遮光50%就能保持“勾魂”的状态。 最近有不少的花友发现自己买回来的山地玫瑰原本绿油油的叶片慢慢变黄，做了一些措施也没效果。下面小编给大家分析一下原因及解决方法。
山地玫瑰叶子发黄的原因 山地玫瑰外围叶片逐渐变得枯黄，这是山地玫瑰进入休眠期的正常表现。 进入休眠期的山地玫瑰底部叶子有枯黄，而且叶子开始包裹起来，形似玫瑰。 温度在30℃左右时，山地玫瑰就会进入休眠状态。但根据个体差异和地区差异，有的山地玫瑰在20℃左右就进入休眠了，有的30℃以上依旧没有休眠。
山地玫瑰叶子发黄解决方法 把山地玫瑰放置在全天通风的地方，但避免直射光，要遮住50%的光。 进入休眠期，浇水量逐渐减少，一周一次的改成10天一次或者2周一次，等完全叶片包起来就只能一个月浇一次，而且不能浇透，只能沿着盆壁稍微浇一点就成。

Potatoes are easy to grow, and the plants can be highly productive if grown under the best conditions. Oklahoma gardeners are fortunate to have a climate well-suited to growing potatoes, and starting your plants at the right time will help make sure your crop is a bountiful one.
Time Frame Potatoes are considered cool-season vegetables. They are not particularly sensitive to frost, and can be planted earlier than more tender garden plants. You can plant potatoes from mid-February to mid-March. If you live in southern Oklahoma, you should plant during the earlier portion of this range. Considerations Potatoes grow best in soil that is well aerated, moist and well drained; avoid compacting the soil. A pH between 5.0 and 5.5 is ideal. Potatoes grow well in sunny conditions, but excessive heat and lack of moisture reduce yield.
Sweet Potatoes Sweet potatoes are less hardy than regular potatoes, and should be planted between May 1 and June 20.

Grow fresh vegetables all year in Phoenix. The hot summer sun is a good thing for the right vegetables. Thoughtful garden design protects plants from too much sun. Irrigation and shade are key ingredients to enjoying the fruits and vegetables of your labor through summer's heat.
Irrigation Irrigating vegetables is a balance of the right amount of water at the right time of day. Thorough watering early in the day provides a reservoir from which plants can draw through the heat of the day. Drip or soaker irrigation is preferred, because water droplets on vegetables or leaves turn into magnifying glasses concentrating sunlight and burning the plant. Overnight watering contributes to molds and soil-transmitted disease. Missing one day's irrigation can kill plants in the summer. Shade Peppers, corn, most tomatoes and melons thrive in the heat and sun all day long. Most herbs, basil is an exception, need shade from direct sunlight. Other vegetable plants, such as leeks and eggplant, also need protection from direct afternoon sun. Shade cloths, readily available in the Phoenix area, are easily installed over sensitive plants. Monsoon Protect plants from violent summer monsoons and their wind, hail and heavy rain by using poles, stakes or tomato cages to keep plants from breaking during the pummeling. Ensure shade cloth is well anchored and has wind flaps to reduce the chance of it sailing away in the storm. Dust Dust on leaves interferes with transpiration. Gently wash dust off leaves with a light spray late in the afternoon or early in the evening. Carefully apply water to leaves and avoid saturating below the soil surface. Mulch Mulch benefits the Phoenix vegetable garden by helping retain water and preventing weeds. Chunky mulch, such as a bark, allows airflow at ground level, depressing soil temperature and protecting roots.
Container Gardens Direct sun turns containers into ovens, baking vegetable roots. Any plant in a container needs to be shaded, beginning at midmorning. Irrigate containers twice a day to maintain a cool soil temperature. Potted soil is less susceptible to disease allowing for the twice-a-day watering.

Potatoes (Solanum tuberosum) are native to the Andean mountains, and well-suited to Colorado's rugged geography and varied climate. Colorado is the fifth to sixth largest producer of potatoes in the United States, with the San Luis Valley in southeastern Colorado producing 90 percent of Colorado's commercial potato crop. While not all of the more than 5,000 varieties preserved in Peru are available in Colorado, hundreds of varieties, from early to mid- to late season types, grow well in Colorado.
When to Plant Potatoes are tubers and herbaceous perennials, hardy in U.S. Department of Agriculture plant hardiness zones 2 to 11. Plant potatoes four to six weeks before the last frost, when the ground temperature has warmed to 40 to 50 degrees Fahrenheit. In the San Luis Valley, parts of the Western Slope and other areas of Colorado with an elevation below 7,000 feet, plant potatoes in late April to early May. In more mountainous regions, wait until mid-May. Potatoes can withstand light frost, though it will kill emerging leaves. The leaves will grow back and the plant will continue to grow, though repeated freezing depletes reserves in the seed tubers. Site and Soil Choose a location where the potato plants will receive at least six hours of sunlight each day. Sandy, loamy soil with a pH of 4.8 to 5.5 is ideal, though some varieties will push through clay soils and most will tolerate a more alkaline pH level. Do not plant potatoes in the same location each year, and do not plant them where other nightshade family plants were grown the previous season. Nightshade family plants include tomatoes, eggplant and peppers. Choosing Potatoes Seed potatoes look just like the potatoes you eat, though potatoes from the grocery store may have been treated to prevent sprouting. You can replant potatoes you grew the previous year, but after one or two growing seasons, the potatoes will no longer produce well. Seed potato producers grow seed potato from the sprouts that emerge from potatoes. These sprouts are rooted and cultivated to produce the seed tuber. Any seed potato imported into Colorado must be certified as free of disease.
How to Plant Seed potatoes that are 1 to 3 ounces, or about the size of an egg, can be planted whole. Cut larger seed potatoes into pieces of about the same size, as long as each piece has at least one or two "eyes" or sprouts. Handle seed potatoes carefully, taking care to not break off the emerging sprouts. Dig a trench 6 to 8 inches deep, and plant the seed potatoes or pieces 18 inches apart, in rows 2 feet apart. Cover them with 4 inches of soil. Water well and check the moisture level where the potatoes are growing to avoid overwatering. Potatoes can withstand less water, while too much may cause the tubers to rot or develop diseases. Sprouts should emerge in about two weeks; when they are 8 inches high, hill the plants by raking up soil from the sides of the bed to add another 4 inches of soil around each sprout. Repeat this hilling process every two to three weeks as the plants grow, taking care to not disturb the soil where the tubers are growing. Be sure to cover any tubers that push to the surface with soil.

Homegrown vegetables always have more flavor and taste than store-purchased products, including onions. Most homegrown onions start with seeds or what is called seed sets, but Egyptian and potato onion varieties can grow from vegetative parts of the original onion plant. Potato, or multiplier, onions form an underground compound bulb from the mother bulb. This compound bulb is composed of six to 12 individual onion bulbs. Egyptian onions, on the other hand, send up a shoot with tiny bulblets on top for planting. Gardeners primarily grow multipliers and Egyptian onion to harvest as green onions in the spring. They sometimes are known as winter onions.
Step 1 Prepare the soil where you intend to plant the onions by adding organic matter in a ratio of one part organic matter to two parts soil. Work the mixture with a shovel into the plot at a depth of six to eight inches. Onions need a rich, loamy soil that will drain well. Step 2 Harvest the attached compound bulbs from the mother bulb for either type of onion. Carefully dig the multiplier onion's mother bulb from the ground and separate the attached smaller onion bulbs from it. Cut off the bulblet cluster from the center green stem on the Egyptian onion and separate the bulblets. Step 3 Plant bulbs or bulblets one to two inches deep and spaced three to five inches apart. Dig a hole for each onion piece, place the onion pointed end up, and cover it with the amended soil. Gently pat down the soil surface to eliminate air pockets and ensure good contact between the piece and the soil.
Step 4 Apply a fertilize formulated to a 1-2-2 ratio, like 5-10-10, following the instructions, every four to six weeks until the first frost. In the spring, apply one more feeding when the temperatures begin to warm. Onions are heavy feeder and require additional supplements of phosphorus and potassium, but overfeeding can produce soft bulbs or burn plants. Step 5 Apply three to six inches of mulch over the planted onions in colder climates when the temperatures drop to freezing to protect growing onions. Remove the mulch once temperatures warm in the spring.

You've done all the work to get them in the ground and keep them healthy as they grow. When the harvest comes in, how do you know it's the perfect time to pick your glowing yellow squash from its home in the garden? Knowing when to bring the squash inside so that you can enjoy the fruits of your labor is a matter of knowing color, firmness and length. This information can also help you pick the best vegetables at the grocery store or the farmer's market.
Peak Performance Picking squash at its peak ensures the highest level of freshness, crispness and flavor. Yellow squash is ready to pick when it is still young and firmly attached to the vine. It should feel firm and rather heavy for its size. The skin should be a bright hue and have a healthy consistency. Soft spots or withered areas could mean you have a watering issue. If caught early, the taste and texture of the vegetable should not be diversely affected. If the stem begins to wilt, again look at your water rates and adjust. Don't pick fruit before they get to at least 4 inches in length. They can grow as large as 8 inches or more, so check the heft to know when it is ready to remove from the vine. Growing Season Squash should be ripe 50 to 60 days after a seedling is planted in warm spring soil. It will continue to blossom and provide vegetables throughout the summer. You may want to protect the vines with a shade cloth during the hottest parts of the season. Check the crop regularly so you don't miss out on peak picking time. This can also alert you to birds, pests or animals that have found your yield and are attempting to take some for themselves or damage your growing garden.
Tips and Tricks Sometimes, it is hard to know when it is too late and the vegetable has gone bad. It can look fresh but taste mealy. Don't let the squash get too long or heavy as it will affect the flavor. A good rule is to harvest vegetables three to four times a week, letting the fruit ripen naturally. Unlike some other crops, such as tomatoes and avocados, squash doesn't ripen as well once it has been picked. If it droops into the dirt, you may want to prop up the ripening vegetable in order to keep it away from pest and rot. If you can't scratch the skin of the squash with your fingernail, it is overripe.
