Arranging greenhouse at home: cactuses and succulents

Hanging cactus typesEvery year different types of cactus plants and succulents become more and more popular as house-plants. And it can be easily understood: the variety of extraordinary forms of these plants, their slow growth, their unpretentiousness and relative resistance to insects and disease have contributed to their popularity in flats and houses.

Well, I’ve already pointed it out in What’s Cactus? that all these different cactus types are succulents, but not all succulents are cactuses, and we should keep that in mind. A succulent is any plant that can keep water either in its roots, leaf or stem.

Most types of cactus and succulents can be raised on a window-sill. As a matter of fact, succulent plants need bright light and should be exposed to sun at least 4-5 hours a day. It is advisable to turn the plant and change its place every few days. But remember, the so called tropic cactus types, such as Thanksgiving, Easter, or Christmas cactus, should only be raised in filtered light. For such succulents as Gasterias, Aloes and Haworthias direct sun is also nit recommended.

One more important tip to remember – never let succulents and cactuses stand in water. They should be watered only if soil is dry.  The planting pots should have good drainage with good soil and sand.  Never fertilize soil in winter, when the plant rests.  Soil should be fertilized only in late March to October.  Different types of cactus plants should be repotted once a year.  New post should be clean and contain new potting soil.  Nevertheless, cactus and succulent plants can be planted in the same pot, but be careful to take plants with the same light and water demands. You can look more “fast tips” in ABC of  Cactus Care.

Tropic cactus types as well and many other succulents look marvelous in hanging baskets. These cacti usually flower in the short days of fall and winter. Holiday cacti (Christmas, Easter and Thanksgiving cactus) planted that way will be the best decoration of your house especially if there’s not sufficient amount of space. Look around. It often happens that there’s an empty corner or window-sill in your living room, bedroom or sitting room that needs “something.” Cactus and succulent plants are undoubtedly that “something” that you might need!

Watering different types of cactus plants

It goes without saying that every type of cactus needs an individual approach. So in order to water your cactuses properly, you should take into account a number of factors. But all in all, the following cactuses require more watering:

1. Hygrophilous cactuses
2. Growing cactuses
3. Cactuses with big roots
4. Cactuses in earthenware pots
5. Cactuses in sandy soil
6. Cactuses kept in high temperature and dry air

And, on the contrary, you should be careful with watering of these cactuses:

1. Xerophilous cactuses
2. Cactuses that are at rest
3. Cactuses with small roots
4. Cactuses that are grown in plastic pots
5. Cactuses clay soil
6. Cactuses kept in low temperature and humid air

In summer I water my cacti just like the other houseplants – just when the soil gets dry, except cool rainy days. In autumn watering should be reduced gradually, and in winter it should be stopped at all – to make dry and cold wintering for your prickly friends.

It’s better to use rainwater, but you can use tap water settled for a day or two. It must be warm – about 30-40 C°. If you put a hand in water with such temperature, you will feel neither warmth nor cold. I seldom use water of room temperature, especially when it’s cool outside. The fact is that cactus roots can’t absorb water, which temperature is lower than 10-12 C°. If it’s about 20 C° in the room, the soil in the pot is colder. The temperature of the water you poured out on this soil slumps. And a cold, moist soil is extremely dangerous for cactus roots.

The best time for watering is in the evening in summer and in the morning in winter. The water should not get on the stalk of the cactus plant, watch it carefully. And remember that every cactus can bear lack of water, but its excess could be baneful.

On the other hand, a lot of cacti suffer just from water shortage in hot summer days: many collectors don’t know that cactus absorbs only a few percents of water together with nutrients dissolved in it. The rest of water is used for the cooling of the stalk through evaporation to protect it from overheating. Water shortage in hot summer period is very harmful.

Hot days and cool dewy nights are typical for the most regions of America where cacti grow. Dew and fog can be replaced by spraying, that has an excellent effect, if you meet some simple conditions. For my collection I stick to these rules:

1. Never spray cactus, if the weather is cool and damp – the stalk may begin to rot.
2. Use a small sprayer that pulverizes water to fog, but not to big drops.
3. Use only boiled and hot water, because its temperature stumps during spraying.
4. Hygrophilous cacti that have leaves, for example Christmas cactus, like not only sprinkling, but also warm shower. It’s undesirable to spray your cactus late at night because of a quick temperature drop.
