One such unique succulent is the Echeveria Longissima. Caring for this beauty is no big challenge, but you still need to know a few important things about it.

Without further ado, here’s everything you need to know about caring for a Echeveria Longissima.

Succulent Description

Like most members of the Echeveria genus; the Echeveria Longissima is a beautiful succulent with fleshy, green rosettes. This spring green color fades into reds at the margins, creating a gorgeous green-red gradient. Its colors vary: pale green at the middle, red at the base, and leafy green in the apex.

When a Longissima flowers, it takes on a bell shape. These bell-shaped flowers are usually 1.2 inches long. As for the leaves, they measure around 1.8 inches long and 0.8 inches wide.

Its colors vary: pale green at the middle, red at the base, and leafy green in the apex.

Care Guide

Caring for this plant isn’t that different from caring for other Echeverias. However, there are a few important things that you should know.

Temperature

The Echeveria Longissima is temperature-tolerant. This plant is happiest when kept in a non-humid and warm environment. It also prefers about ten degrees of difference between night and day temperatures.

In the summer, the Longissima prefers a temperature between 65°F and 70°F. If the temperature goes beyond 85°F, it’s best to leave the plant in some shade. At this stage, most plants shut down and stop respiring. Then, when temperatures decrease at night, they open their stomata to breathe again.

During the winter, you can keep your succulent healthy by moving it indoors. Try to keep it in a frost-free, sunlit area. In these colders months, the Longissima prefers a temperature that’s somewhere 50°F.

Light

This succulent prefers full sun. After all, the Echeveria species are native to Mexico and Central America, where the climate provides plenty of sun and warmth. The Longissima can even change colors if put in direct sunlight.

However, you shouldn’t let them simmer under the sun 24/7. This can stress them out, especially if done during the hotter summer months. It can even cause sunburn. In this case, all you can do is cut off your succulents head, and wait for it to grow back again.

To avoid that fate, it’d be best if you shielded your Longissima from two things: extreme light changes, like when moving the plant from indoors shade to the outside in the glorious full afternoon sun. You can do this by keeping your succulent in the sun for a few hours a day.

You could even “condition” your succulent to the sun. To do this, start by keeping your Longissima in the sun for a couple of hours every day. Then, gradually increase their exposure to the sun over a week or two until they become fully acclimatized.

In the winter, it’s best to keep your succulent near the brightest window. Sun-rooms and conservatories are also other good options to keep your succulent in. You can keep your Longissima under grow lights on a 14-hour schedule.

Watering

One of the most critical aspects of caring for a Longissima is watering. Here’s the secret: never let water sit inside the rosettes. This can cause rot or even fungal diseases which might result in the plant dying.

As with any other succulent, a Longissima requires careful watering. Remember to avoid overwatering; instead, consider the “soak and dry” method. This method consists of two main steps: soak the succulent’s soil, and wait until it’s completely dried out before watering again. 

Of course, the soak and dry method is best for mature succulents. Young succulents should be drizzled with a light mist every 2-4 days.

Remember to water your succulent every 2-4 weeks. Choosing when exactly to water it depends mostly on your pot size, as well as humidity, soil, and seasons. Generally, it’s best to water more in the summer than in the winter. You could even skip watering for 1-2 days after the soil dries; this gives the root system a boost.

If you notice that the Longissima’s topmost leaves are becoming a bit crispy, then it might be under-watered. This is usually no big deal—unless the whole plant is shriveled at this point; if so, it’ll be difficult to revive. If it’s not, then you should lightly mist the succulent for 1-5 days.

Avoid soaking the succulent, as this may give it a bit of a “shock” and damage it. From there, you want to work your way up your normal watering schedule.

Fertilizer

Good news! These succulents rarely require fertilizers. They can grow well without a lot of nutrients. However, you can choose to give your plant a boost, especially if it’s looking a little tired.

In that case, it’d help if you’d use a water-soluble fertilizer diluted to half strength. You must remember to use less than recommended. You could also use a slow-release fertilizer at the start of spring.

If you want to give your succulent more nutrients, you could use worm castings. When sprinkled on the soil, it gives your plant all the nutrients it could need.

Soil

Succulents generally prefer well-drained soil, and the Longissima is certainly no exception. For healthy roots, you must avoid keeping the Longissima’s soil damp. To encourage good drainage, you should opt for quality soil mixed with something like perlite.

Potting soil isn’t the only important thing. Pots are important: an unglazed clay pot can be good for your soil, as it lets water evaporate.

Another way to encourage a well-drained soil is drainage holes. You could purchase a container that has them or even poke them. Whatever you choose to do, don’t underestimate drainage holes; they can help stave off rotten roots, which are caused by overwatering and excess moisture.

Yet, it’s not only dampness that the Longissima’s soil can’t cope with. It also can’t cope with the cold, which is why you should remember to move your plant to a warmer nook during the winter.

Overall, the ideal soil should be slightly acidic (pH=6) and slightly tough. If you squeeze it when it’s moist, it should crumble when released.

One thing you must do when caring for a Longissima is this: remove the dead leaves from the bottom of the plant. These leaves can collect pests. Echeverias are particularly vulnerable to mealy bugs.

USDA Zone

This succulent prefers zone  9b-11b -3.9°C (25°F). In Zone 9b, the minimum average temperature range is 25°F to 30°F. Meanwhile, Zone 11b is the warmest zone in the 48 states. Zone 11b succulents can tolerate cold down from 45 to 50 °F.

Conclusion

With its vibrant reds and greens, it’s no doubt that the Echeveria Longissima is a beautiful succulent. However, the truly great thing about it is that it’s low-maintenance. You just need to watch your watering and let your succulent enjoy the sun.

Good luck!
