Why Drought-Tolerant Flowers Need Less Water in Autumn and 5 Cold-Hardy Flowers: Autumn Care Tips You Need to Know

In autumn, as the weather gradually turns cooler, the growth rate of many flowers begins to slow down, and their water needs decrease accordingly. For drought-tolerant flowers, autumn is a period when watering must be strictly controlled. Today, let us learn together why drought-tolerant flowers need less water in autumn, and introduce five flowers that "can't be killed by drought", which need even less watering in autumn.

Why drought-tolerant flowers need less water in autumn

Slower growth: In autumn, temperatures drop, and the growth rate of drought-tolerant flowers gradually slows down, so the rate at which they absorb water and nutrients also decreases. If you continue watering at summer levels at this time, it is very easy to cause water to accumulate around the roots, leading to problems such as root rot and leaf rot.

Avoiding disease: Air humidity in autumn is relatively low, but if the soil is too moist, various pathogens will breed, increasing the chance of flowers becoming diseased. Watering less helps keep the soil slightly dry and reduces the occurrence of disease.

Promoting dormancy: For some drought-tolerant flowers, autumn is the stage when they enter dormancy. Reducing the amount of watering helps them enter dormancy better and accumulate energy for next year's growth.

Ball cactus

The ball cactus is a typical drought-tolerant plant. Its fleshy stem stores a large amount of water, allowing it to sustain life even under dry conditions.

In autumn, the watering of ball cacti should be strictly controlled, usually watering 1-2 times a month is enough, and each watering should only be done after the soil has completely dried out.

Aloe

Aloe also has strong drought tolerance. Its leaves are thick and juicy, rich in water. Aloe's watering amount in autumn should also be reduced accordingly, keeping the soil slightly moist is enough, avoiding overwatering that causes root rot.

Jade plant

101-2 months 1 time is enough.

Elephant bush

The elephant bush is also a succulent. Its leaves are thick and it has relatively strong drought tolerance. Autumn is the vigorous growth period for the elephant bush, but the amount of watering still needs to be controlled to avoid the soil becoming too moist; keeping the soil slightly moist is enough.

Kalanchoe

Kalanchoe is a fleshy plant with thick leaves and relatively strong drought tolerance. In autumn, kalanchoe's growth rate slows down, so the amount of watering should be reduced to avoid the soil becoming too wet; keeping the soil moist but not waterlogged is enough.

Precautions for watering drought-tolerant flowers in autumn

Check soil moisture: Before watering, first check the soil moisture. If the soil surface is dry, you can water; if the soil is still moist, watering should be postponed.

""Pay attention to drainage: Make sure the bottom of the flower pot has drainage holes to avoid water accumulation causing root rot.

Control water quality: Drought-tolerant flowers have relatively high requirements for water quality. It is best to use tap water or rainwater for watering, and avoid using alkaline water.

Maintain ventilation: In autumn, the growing environment of flowers should be kept well ventilated, which helps reduce the occurrence of disease.
