What do your 植物s look like in the middle of summer? Do they thrive despite the hot temperatures?
Or do they look more like this?
Throw in a heatwave, and your lovely, attractive 植物s may be suddenly struggling to survive.
Whether you live in the desert Southwest or more temperate climates, 如果你的花园没有为炎热的夏天做好准备,这可能会发生在你身上.
So, how do you know if your 植物s are handling the summer heat?
在一天中最热的时候,在花园中散步,寻找叶子枯萎、变黄或褐变的迹象. All of these can indicate heat stress.
好消息是,你可以为你的景观隔热,享受一个充满吸引人的植物的花园,尽管夏天的炎热天气.
Here are 5 tips to help you heatproof your garden:
#1. Use native or 植物s adapted to your climate.
This is perhaps the most important tip for having an attractive, 低维护的景观充满了美丽,全年蓬勃发展.
Native (or adapted) 植物s have unique characteristics that help them to handle the local climate, including the heat of summer AND the cold of winter.
经常, betway旗舰版下载发现自己周围到处都是植物(通常是大叶子),它们在高温下挣扎求生, 夏季. This results in unattractive 植物s that we work hard to help sustain them until cooler temperatures arrive. 通常,这些植物最适合生长在不太炎热的气候中.
Langman’s 圣人 (Leucophyllum langmaniae)
让betway旗舰版下载来看一个例子,这个朗曼的圣人拥有的适应性,使它能够在没有过度压力的情况下应对充足的阳光和110+温度.
Notice that the flowers have small hairs. So do the leaves, giving them a slightly grayish cast. These tiny hairs help to reflect the sun’s rays, which lowers the temperature of the leaves and flowers.
Mexican Honeysuckle (Justicia spicigera) and Shrubby Germander ‘Azurea’ (Teucrium fruticans ‘Azurea’)
植物应对高温的另一种方式是长出小叶子, which limits the amount of water lost, which helps them to deal with hot, 干燥温度.
Here in the desert Southwest, t在这里 are many native 植物s that are used as well as 植物s from Australia and other arid regions, which have similar climates.
#2. 提供阴凉
Adding shade to the garden can provide relief from the hot sun as well as cooling air temperatures. 树荫有利于植物,也可以为房子提供凉爽.
*It is important to note that it can be hard to grow many 植物s in dense shade – especially flowering ones. 然而, 使用能提供过滤遮荫的树木,既能提供足够的遮荫,又能给植物提供足够的阳光.
#3 水很深的 and infrequently
植物需要水来生存,毫无疑问,它们在夏天最需要水. 然而,betway旗舰版下载经常给他们浇太多的水,太浅了.
Shallow watering keeps roots close to the surface of the soil, w在这里 the soil temperatures are hot, and the water dries up quickly.
深层浇水是灌溉植物的合适方法,因为在土壤较凉、湿润的地方,深层根系可以生长. As a result, you do not need to water as often.
“经常浇水的植物能更好地抵御高温.”
灌木应该浇水到2英尺深,多年生植物和地被植物应该浇水到18英寸深. 你可以通过在土壤中插入一根钢筋来确定你浇水的深度(在你浇水之后),看看你需要灌溉多长时间. 平均2小时是灌水到所需深度的时间.
在我的在线课程中, Desert Gardening 101, I teach my students that watering deeply is as important as the time of day that you water. The best time to water is early in the morning. 在下午给植物浇水不是很有用,因为植物在那个时候将它们的资源分配给在高温下生存的植物,所以它们不能有效地吸收水分.
#4 Mulch around your 植物s
不足为奇的是, 护根物有各种各样的好处,不仅仅是对花园的防热.
在夏季,护根物有助于降低土壤温度,同时保持水分——这对帮助植物在高温下茁壮成长至关重要.
A bonus is that they also help to prevent weeds from taking root.
让betway旗舰版下载花一分钟重新思考一下什么是优秀的覆盖物.
While shredded bark and wood chips may come to mind, did you know that fallen leaves, pine needles and even fallen flowers can also serve as a mulch? That is how nature does it.
So, the next time you are tempted to whip out your leaf blower, how about directing it toward the base of your 植物s w在这里 the leaves and flowers can serve as a mulch? 当植物腐烂时,它们还可以帮助改善周围的土壤.
#5 Ditch flowers in favor of succulents in containers
而在秋天,在容器里种漂亮的花是相对简单的, winter and spring-summer can be another matter entirely. 通常,在整个炎热的夏天,很难在花盆中种植开花的一年生植物.
原因是盆栽植物根部周围的土壤比在地下生长的温度高. 对于外层6英寸的土壤来说尤其如此,它会随着空气温度和热容器的升温而升温. 结果,一年生植物会在夏天枯萎并难以开花.
多肉植物是全年享受吸引人的容器种植的好方法, 不仅仅是在夏天. 它们储存水的能力使它们成为容器的绝佳选择.
If you want to grow something else besides succulents, how about trying heat-tolerant shrubs? Bougainvillea does great in pots as does lantana.
Another tip for containers is to leave them empty in the 夏季 and wait until fall to 植物 them.
当考虑到在炎热的气候中在容器中种植植物, bigger is better – at least 2 feet wide at the top. 锅越大, the more soil and t在这里fore, more insulation for the roots from the hot outer zone.
**So what can you do if you do have 植物s that are struggling in the heat – particularly during a heatwave? Other than replacing them, 你可以为他们提供临时的遮阳,比如在庭院里放置一把椅子,这样就可以保护他们免受下午阳光的照射. 晚上在植物和周围区域喷洒少量的水可以帮助降低温度——不要在太阳出来的时候这样做, or you may burn the foliage.
