Questions About Krysna crassula

Watering

Temperature

What should I do if I water my Krysna crassula too much or too little?

Underwatered Krysna crassula

Krysna crassula and other succulents can endure long periods without water, so it’s unusual to find one of these suffering from underwatering. But, if you somehow forgot about your plant and neglected to water it for a month or more, you’ll probably find your Krysna crassula looking thirsty or with some damage from lack of watering.

It is very easy to identify an underwatered Krysna crassula. Plant look lacklustre and wrinkled. Some may have dried up completely, turned brown and crispy, or dropped off the plant. And of course, the soil will be completely dried out.

If your Krysna crassula is thirsty and underwatered, give it plenty of water as soon as possible. Submerging the pot entirely in water for about 5-10 minutes is a good way to make sure the soil and plant are rehydrated properly. When you feel a sense of moisture on the surface of the soil with your finger, it means the watering is done properly.

Overwatered Krysna crassula

Overwatering is dangerous to Krysna crassula and can be fatal to your plant if you don’t remedy the situation. Too much moisture over time leads to root rot, which prevents the roots from being able to absorb nutrients and water from the soil. Root rot occurs when wet conditions allow fungi and bacteria to flourish in the soil and feed on roots. When you find that it's overwatered, you'd better change the growing conditions, place it somewhere with more air ventilation and adjust water frequency, for example.

The symptoms of overwatering are yellow, swollen, and translucent organs that may even burst open from being over-full with water. If the problem continues without being treated, plant might turn brown or black, and fall off the plant at the slightest touch. Be sure to check the soil to determine if overwatering is the culprit, as some other issues can cause similar symptoms.

It’s a bit difficult (but not impossible) to save an overwatered plant. The key is catching it early before a lot of damage has occurred. If the roots become rotten, it is likely to kill the entire plant. If you suspect you have overwatered your Krysna crassula, the first step is to remove it from its pot and check the roots and soil.

After removing the plant from its pot, gently remove wet soil from around the roots and then rinse them clean in room-temperature water. This helps with removing fungus that might be lurking in the soil and allows you to get a better sense of how healthy the roots are. If your plant has already developed root rot, you will see roots that are dark brown or black, soft, mushy, or slimy.

If the majority of the roots are already affected by root rot, it may not be possible to save the plant. In this case, it is best to remove any healthy stem and try to use these to propagate a new Krysna crassula. If, on the other hand, only a portion of the roots have succumbed to rot and other healthy roots still remain, there is a chance it can be saved.

Use a sterilized cutting tool to remove any unhealthy-looking roots. Once you're left with only the firm, pale roots, it’s a good idea to dip them in a fungicide to kill off any remaining spores. After that you can repot your Krysna crassula in fresh, free-draining potting soil. While this does not always work to save a succulent with root rot, in most cases this plant will be able to make a full recovery and will put out new growth starting in the next growing season.

How often should I water my Krysna crassula?

There’s not a hard-and-fast rule for how often to water Krysna crassula. The best way to determine this is to check the soil and only water when it’s bone dry. You can either stick your finger in the pot or use a moisture meter to check the soil below the surface. When you plant it in a deep pot, you can do this with a stick or chopstick. If it feels even a little bit moist, wait a few days and check it again.

Most people will need to water Krysna crassula about every two weeks in summer and once a month in winter, but there are several factors that can change the frequency. The section below lists some considerations that can help you to determine how often to water.

What should I consider when watering my Krysna crassula?

There are several environmental conditions that will affect how your Krysna crassula needs to be watered, including the container size, soil type, temperature, and humidity.

First off, the container and soil you use will determine how often to water and how much water to use each time. Be sure you use a container with plenty of drainage holes in the bottom so extra water can escape the pot. A small container has less room for soil, meaning it won’t hold as much moisture, while a larger pot will stay wet longer and need to be watered less often. It’s important not to keep your Krysna crassula in an oversized pot as this can easily lead to overwatering. When repotting, move to just one size larger than the current container. A shallow container works better than a deep one, since Krysna crassula has shallow root systems.

Krysna crassula will need to be watered less often in winter and more often in the active growing season in spring and autumn. During the winter, growth slows down considerably and the plant isn’t using much energy or water. There is less water lost to evaporation in cooler winter air, meaning that soil stays wet for much longer than it would in the summer.

This also applies to the general climate around your home. If you live in a humid location with a lot of rain, you will need to water less often than if you live in a dry, arid climate. Remember that conditions at the same geographic location can vary significantly with the season and the use of indoor heating and air conditioning.

Outdoor Planting

If Krysna crassula is planted in the ground, after establishing a root system, it shouldn’t need supplemental water beyond what it receives through precipitation and dew. But if there is a long dry period, you may want to water occasionally. In other areas where Krysna crassula can only be grown in a container, this plant can be moved outside in the spring and summer when the temperature is proper and then brought back inside when temperatures start to drop. A potted Krysna crassula kept outside usually needs more water than the same plant kept indoors, because there is a lot more sun exposure even on a shaded porch.

How to water Krysna crassula?

The best way to water Krysna crassula is to soak it thoroughly and then allow it to dry out before it gets watered again. Since this plant is somewhat drought tolerant, you can let it get quite dry before watering again. It is always better to give this type of plant too little water over too much.

When you water, make sure the soil gets thoroughly soaked throughout the whole pot. Don’t pour the water in just one spot, but rather try to go around the whole rim of the planter to be sure that it has a chance to get wet on all sides of the plant. The correct amount of water will depend on the size of your container and how much water your soil absorbs. Give your Krysna crassula enough water that it drains out from the drainage holes and then (ideally) leave the drained water in the saucer for about 20-30 minutes to absorb into dry pockets of soil. After that, discard any excess water that’s still in the saucer to avoid the soil getting waterlogged.

Bottom-watering is also an excellent method for Krysna crassula, as you can be sure that the soil gets thoroughly moistened. This process involves placing the pot into a saucer of water and allowing the soil to absorb moisture through the drainage holes. You will know that the soil has absorbed enough water when the top layer is moist. This takes a bit more time than top-watering, but is almost foolproof in getting an even distribution of water throughout the pot.

The original habitat of Krysna crassula is relatively dry with little rain, but when it rains, the soil will be thoroughly moistened. So you can mimic this situation by bottom-watering your plant when the soil is totally dry. Deep soil bathing is better than frequent light watering for Krysna crassula.

What's the ideal temperature for your Krysna crassula?

It is more suitable to keep the Krysna crassula in a particular range of conditions. Temperatures the same as 75-90℉ (25-32℃) are ideal for it. During the early winter season, the temperature shouldn't go below 75℉(25℃) for Krysna crassula. You can even move it indoors as it will have better protection from the extremes.

Despite that, the Krysna crassula can survive in some extreme temperatures. Sometimes can survive in low temperatures like 50℉ (15℃), but it is not ideal. You should bring it inside if winter conditions are expected outside.

How should I adjust the temperature for my Krysna crassula during different growing phases?

Krysna crassula has different growing phases. In the first stage, the dormant seed grows and transforms into a seedling. The dormant seeds need the appropriate conditions in their surroundings to grow as their seeds need a temperature of 75-90℉ (25-32℃) to germinate. The ideal time to make it grow vigorously is during the summer, as the most suitable temperature is around 85℉(30℃). You can adjust the placement of your Krysna crassula from indoors to sunlight during the hot summer months to receive enough sunlight.

How can I keep my Krysna crassula warm in cold seasons?

It's advisable to bring your Krysna crassula indoors to avoid the harsh winter conditions. People opt to buy different types of grow light to provide enough sunlight for the plant. However, if your home is not extremely dark, it is not essential to buy these lights. Keep your plants where they will get the most sunlight possible. There should be sufficient light to keep the Krysna crassula thriving in winter. If you have several Krysna crassula, then keep them rotating so that they all receive enough sunlight.

Avoid placing your Krysna crassula too close to the window if you live in northern areas with frigid weather. The cold may be extreme to them, due to which they might get damaged.

What happens to my Krysna crassula when the temperature is too high or too low?

Your Krysna crassula can grow better in summers and do better in warm temperatures 90℉(32℃) but you should protect it from temperature extremes during hot climates.

However, during winter, it is better to keep your plant dry. Krysna crassula do well in temperate climates having temperatures between 75-90℉ (25-32℃). However, some gardeners can expose their Krysna crassula to extreme temperatures causing stress in their plants. While high temperatures ranging between 90℉ and 95℉(32-35℃) can help maintain the deep colors for Krysna crassula, you must be careful when trying out such experiment. During the hot summer season extremely high temperatures can burn your Krysna crassula damaging their stem and root system. During the hottest time of the day (when the temperature is extremely high), consider relocating your plant to a shaded place or protect them with a shade cloth.

How should I adjust the temperature for my Krysna crassula in different seasons?

In summers, high temperatures make the growth of Krysna crassula slowed down to survive in too hot a temperature.

As the cooler periods and rainfall begins, the Krysna crassula starts growing. If the place you live in has hot summers and warm winters with more rainfalls, you aren't required to change anything.

However, if you live in a place with cold winters, you should let your Krysna crassula grow more in summer and rest in winter. It is because there is not enough sunlight for Krysna crassula to grow in winter.

You can help your Krysna crassula enter dormancy if you live in a place with cold temperatures by decreasing the temperature to 50℉ to 75℉ (15℃ to 25℃).

How can I keep my Krysna crassula warm without a heating pad?

To withstand freezing temperatures outside, as a solution, you can insulate your Krysna crassula with frost cloths, row covers, tents etc. You can also mulch your Krysna crassula with small rocks. Mulching the Krysna crassula soil will provide warmth to your plants and will not let you over-water the plant.

How can I protect my Krysna crassula from temperature damage?

Krysna crassula is adapted to sunlight and requires sufficient sunlight for healthy growth. You can place it in an outdoor environment without any shade. However, Krysna crassula shouldn't be kept for a long time in the blazing sunlight in the hot summer when it requires to be put under shade so that extreme temperature doesn't damage them. If the winter is extreme in our area, you must keep your Krysna crassula indoors to keep them away from frost.

What are the tips and precautions for keeping my Krysna crassula at the right temperature?

Increase water and fertilizer during the growth of plants in spring and summer. Prevent your plant from receiving too much sunlight. To cool plants, spray water around them when the temperature is exceptionally high but don't put water on their stem.
