These flowers are very drought-tolerant; they won't die even if watered once a month
Desert Rose
The desert rose is native to East Africa and southern Arabia. Just look at its place of origin - that's a thoroughly dry region, so how could it not be drought-tolerant? Gardeners have verified this firsthand: it wasn't watered for half a month, yet it still grew vigorously. Just look at that drought tolerance.
Basically, you just need to follow the rhythm of "water when dry, let dry between waterings." If you still can't tell, Huahua will teach everyone a simple method: squeeze its big bulbous base. If it has gone soft, it's time to water! Or poke your index finger into the soil up to one knuckle (about 2-3CM deep); once it no longer feels damp, you can water.
Sun God
The Sun God is native to subtropical regions, and its ideal environment is naturally high temperature and high humidity. But don't think it's a case of "hard to go from luxury to simplicity" - the Sun God is very drought-tolerant!
For gardeners growing it in the north, because autumn and winter weather is relatively dry and temperatures are relatively low, you absolutely must not water too much. The best approach is alternating dry and wet. The Sun God is managed rather extensively; basically, when you have time and see that the soil in the pot has dried out completely, water it thoroughly in one go. The Sun God is very tough. Of course, if you have time, misting a bit of water on the Sun God is even better.
Ornamental Kale
Honestly, when it comes to ornamental kale, Huahua still prefers the way it looks when it isn't flowering. Moreover, ornamental kale is native to Europe, so it is certainly very cold-tolerant.
From its place of origin you can roughly see ornamental kale's growth habits: cold-tolerant, not waterlogging-tolerant, so you must not water too much. Follow the principle of preferring dry over wet. This plant is actually quite easy to grow: extremely cold-tolerant, able to withstand repeated brief frosts, and also tolerant of poor soil. It's practically a household essential!
Sago Palm
The sago palm is now a very common tree species, found in countless homes. In addition, its leaves differ from those of other ornamental trees, which makes it even more appealing.
The sago palm grows slowly and dislikes heavy watering. Especially in spring, autumn and winter, watering must strictly follow the principle of alternating wet and dry - that is, after watering once, wait until the potting soil looks dry before watering a second time. In summer, except on rainy days, you should spray water over the leaf cluster, but avoid waterlogging, otherwise the roots will rot and the plant will die.
Ornamental Pepper
Ornamental peppers come in many colors - red, purple, white, black... But these brightly colored peppers cannot be eaten!
Although ornamental pepper is drought-tolerant, compared with other drought-tolerant plants it falls a bit short. Keeping the potting soil moist is best, but if you don't have time, you should follow the watering method of watering when dry and letting dry between waterings.
Geranium
The geranium is native to southern Africa, a typically arid region, so the geranium is also a very drought-tolerant plant.
Geraniums should not be watered too much; too much water makes the roots rot very easily. Moreover, you can't judge geranium watering by the number of days alone; it also depends on the season. Spring and autumn are the geranium's growing seasons, and basically once the soil surface has dried out completely, you can water.
In winter, the geranium is in a semi-dormant state, and the amount of water can be about 1/4 of the potting soil. At the same time, when watering, water along the edge of the pot. Generally speaking, if the potting soil is not dry, there is no need to water.
Cosmos
Cosmos is native to Mexico, and cosmos has a very likable appearance. I imagine quite a few gardeners have one of these at home, right?
Cosmos is very afraid of waterlogging and is relatively drought-tolerant, so when watering, pay attention: if it's not dry, don't water, to avoid water accumulating below; wait until it has dried out completely before watering. It doesn't matter if you forget to water - this plant is very easy to grow. Basically, plant it in sandy loam and give it plenty of sunlight, and it will give you beautiful flowers.
Marigold
Marigold is native to Mexico and Central America, and is now cultivated throughout our country. Looking at the picture below, everyone should be familiar with it.
Marigold is very drought-tolerant. When cultivating marigold during high-temperature periods, water must be strictly controlled, and slightly dry conditions are best. After rain during the plum rain season in the south, check and promptly pour off any accumulated water in the pot. Just follow the rhythm of preferring dry over wet when watering, and wait until the potting soil is dry before watering. Water thoroughly! Half-measures won't do!
Ageratum
Ageratum is a relatively short little flower, and some people also call it "yizhixiang." It can bloom and bear fruit all year round, provided of course that the temperature is suitable. Its pale purple-blue flowers are very unique and highly ornamental.
A moist environment is the ideal growing environment for ageratum, but this flower is also relatively drought-tolerant, so it doesn't matter if you forget to water it. It will be fine for one or two weeks, but going several months without remembering is no good!
Pencil Cactus
Pencil cactus - this name really is very fitting! It only grows stems, not leaves. Its place of origin is East Africa - perhaps it has no leaves in order to store water in its body?
Yes, the pencil cactus is very drought-tolerant. To adapt to its environment, its leaves have fallen off and degenerated into scales, reducing water evaporation. So during care, really don't water too much, otherwise water easily accumulates at the roots and the plant dies. You must only water after the soil has dried out completely.
ZZ Plant
The ZZ plant is now also a very popular indoor potted plant. It's very easy to keep alive, and the meaning of its name is nice too.
The ZZ plant is native to East Africa, where there is relatively little rainfall, so it is very drought-tolerant, but not cold-tolerant. So gardeners who have a ZZ plant at home should not give it too much love - too much water is more than it can handle. Oh, and remember it must have good ventilation. Watering when dry and letting dry between waterings is great; do not water when it's not dry!
California Poppy
This is a rather special perennial herbaceous plant. It has fairly strong cold tolerance and likes a cool, dry climate; it is not tolerant of damp heat and enters a semi-dormant state in the hot summer, often dying back. Don't worry - it will sprout again after autumn.
It is relatively drought-tolerant. Even if it dies back in summer, it doesn't matter, because in the new year it will grow and sprout again. It simply doesn't care whether there is water or not!
Jade Plant
The jade plant should be a variety everyone is relatively familiar with. The jade plant's leaves are rather thick and fleshy. Generally speaking, this kind of plant is relatively drought-tolerant!
And that is indeed the case - the jade plant is very drought-tolerant. In winter, if the temperature can be kept above 5°C, you can give it water; below 5°C, you must cut off watering, otherwise it is very easily frostbitten. In summer, once the temperature is above 35°C, move it to bright indirect light and gradually cut off water. During the entire summer dormancy, give little or no water. Only when the temperature drops in mid-September can watering slowly resume.
Hens and Chicks
Hens and chicks is an alpine-type succulent that likes a sunny, cool and dry environment. Apart from providing appropriate shade and avoiding scorching sun exposure during high summer temperatures, it needs full sunlight in all other seasons. In winter, restrict watering, and it can withstand low temperatures of -20°C. Yes, you read that right - minus 20°C!
About how often can it be watered? Huahua's way of judging is to look at the soil: if the soil is very dry, then you can water thoroughly once. Hens and chicks won't die from dryness, but it very easily dies from dampness. Let me tell you a secret: one time Huahua didn't water it for a month and it still didn't die!
Echeveria Succulents
There are about 150 species of Echeveria succulents. Their place of origin is the Andes region, and they are relatively drought-tolerant and like dry environments.
Echeveria succulents are really very easy to grow. Basically, once you master the principle of "don't water if not dry, water thoroughly if you do," there's no problem. Huahua keeps a pot of Echeveria glauca and has always just left it outside without paying attention to it, watering only when remembered - and it grew very well on its own!
Alright, these are the relatively drought-tolerant plants!
If you don't want to keep cacti and the like at home, you can pick from these!
