When I started gardening, I fanatically watered herbs. To my mind, plants needed water every four hours. But soon my herbs began to fade. It was a shock to me too when I discovered they fade because of excess water.
How to water herbs in hot and cold periods and which water is the best for plants? How much watering do herbs need? Which factors indicate shortage and excess water in the soil? Which plants are moisture-loving?
Let’s answer these questions.
How to water herbs in hot and cold periods?
The frequency of watering is determined by the season and the nature of the plant. Herbs are watered rarely in winter, except cyclamen, primrose, cactus, etc. But the watering is more abundant from early spring until. We should understand the abundant watering is daily watering, 2-3 days later – moderate watering and once a week and rarer – weak.
It is better to water the plants in the evening in the summer because they use moisture fully at night. In the hot period, the leaves and the soil in the pots intensively absorb the water and we need to water small pots two times a day. We use only clean water, suitable for drinking, including from the well. However, the best is rainwater. In summer, it is necessary to always create at least a small reserve of it. We can put the few pieces of charcoal in a tub with rainwater so that rainwater does not spoil for a long time. The boiled water is not suitable for watering herbs due to lack of air. And hard water is harmful to plants. Sometimes we can find it in the wells, although it can be softened by soda.
The temperature of the water should be the same as the temperature of the air indoors, for this fresh water should stay in the room for at least 12 hours. We need to water our herbs carefully, without blurring the surface. We cannot spray leaves in the sun because droplets of water, like small magnifying glasses, collect sun rays and cause burns to plant, sometimes very serious.
What about cold seasons? We water our herbs once a week or when the soil is very dry. Cactus and succulents are practically not watered in winter.
How much watering do herbs need?
There are different plants in appearance, structure, and origin. It is impossible to offer exact ‘recipes’ regarding the frequency and volume of watering. Some plants do not tolerate a shortage of water and they fade or dry as soon as the substrate dries. If the leaves fall, the plant is often difficult to return to normal. This plant needs to be grown in a substrate that keeps moisture well, based on low-grade peat. But there are other types that prefer rarer watering. They are the majority of cacti and succulents, and all plants with dense, solid leaves or those that form a thick stem.
Observation and good knowledge of plants give us an opportunity to water them at an ideal moment and to give the plant an optimal amount of water. During the period of growth (from the middle of March to the end of September), plants require the most frequent and abundant watering. As a rule, we water twice more often at this than during the period of vegetative rest (from the middle of October to the end of February). In the transition periods, the frequency of irrigation depends on the temperature of the air.
How to water plants with thick stems? At normal temperatures (18-22 ° C in the house) plants with a hard stem, as well as species with dense leaves are watered on average every 5-7 days during the growth period and every 10-12 days in the period of vegetative rest (in winter). Water should fall on the surface of the soil.
How to water herbaceous plants? These plants have no persistent woody stem and form a bush of flexible and thin stems. They are watered on average twice a week during the period of growth and 1 time a week in winter. It is best to use the method of immersion of the pot in water.
How to water the orchids? Forms with pseudobulbs or reed-stems are watered on average 1 time a week throughout the year and only during the flowering period – every 3-4 days. Orchids with thin stems are watered twice a week during the period of growth and 1 time a week in winter. Do not soak the plant’s core and pour excess water.
How to water cacti and succulents? During growth, we water every 6-10 days depending on the temperature of the air and no more than once a month in the winter. If the temperature is low, do not water them at all. For example, a lithops can stay in a pot for about a year without a single drop of water if the room temperature is below 16 ° C.
How to water bromeliads? Pineapple, Aechmea, Guzmania, and others. We water on average once a week throughout the year. In the period of growth, leave the water in the center of the foliage.
Which factors indicate shortage and excess water in the soil?
Factors of the shortage of water:
- We see faded leaves and slow growth or lack of growth.
- Flowers and buds fall of pants and fade quickly.
- We see dried and twisted bottom leaves, brown tips of foliages.
- All leaves fall down.
Factors of excess water:
- There are soft areas with sighs of rotting and slow growth.
- Brown roots and dried, yellow leaves.
- There are brown spots at the edges and in the center of leaves.
- Young and old leaves fall down at the same time.
Which plants are moisture-loving?
These plants are fast-growing, absorb quickly moisture and their leaves are often large. However, moisture-loving plants do not require intensive watering throughout the year. It is necessary to do only during the period of active growth (in spring), and watering should be reduced at other times of the year. Moisture-loving plants are ivy, monstera, passion fruit plant, citrus, palm, bromeliads, columnea, cyperus, tradescantia, azalea, and others.
In winter, these plants often suffer from dryness because of central heating. The soil dries quickly in the pots. It also adversely affects the flowers. However, frequent irrigation causes rotting of the roots. The best way is to put a pot in a large container and fill it with wet peat. But we must control the moisture.
So, watering the plants should be done correctly, taking into account their needs and features of the structure of the root system. Most herbs watered abundantly during the period of vegetation, in the winter – moderately. It is recommended to use water of room temperature. The water jet should be directed so that it does not erode the ground near the roots and did not fall on the leaves. The best time to water is morning or evening. @
