Introducing the string of watermelon, known as Senecio herreianus (now Curio herreianus), which is a popular trailing succulent native to South Africa. It belongs to the Asteraceae family and is loved for its unique foliage and trailing growth habit. It has several other common names such as Gooseberry Plant, String of Beads, String of Pearls, String of Raindrops, Curio herreanus, Senecio herreanus, and String of Tears. 

The string of watermelon is a stunning succulent with trailing stems and egg-shaped leaves, similar to a String of pearls but larger and elongated. It can grow over 2 feet long and can be found trailing from a pot or creeping along the ground. The leaves are green, lined with dark green or purple tones, resembling the rind of a watermelon, and can be deepened by bright sunlight.  

When grown as a houseplant, the string of watermelon can reach a height of about 6-8 inches and spread out in a trailing manner. It's a great choice for hanging baskets or as a trailing accent in pots. 

This plant's flowers bloom from spring to fall and are white or off-white, with small, daisy-like blooms. The plant is known for its ability to attract butterflies and bees with its sweet nectar. Its delicate petals bring a touch of elegance to any garden or landscape. 

You can propagate the string of watermelon through stem cuttings. Simply take a healthy stem cutting, remove the lower leaves, and allow the cutting to dry for a day or two. Then, place the cutting in well-draining soil and keep it slightly moist. Over time, it will develop roots and start growing into a new plant. 

Watering Needs 

Like most succulents, the string of watermelon prefers well-draining soil and doesn't like to sit in wet conditions for too long. Overwatering can cause root rot and other issues, while underwatering can cause leaves to shrivel and drop. 

Before watering, insert your finger about an inch into the soil to check if it's dry. If it feels moist, wait a few days before watering. When watering, ensure that the soil is well saturated until water drains from the bottom of the pot. This ensures that the roots get enough moisture. 

In the spring and summer, during the growing season, water your string of watermelons every 1-2 weeks. In the dormant period (fall and winter), you can reduce watering to once every 3-4 weeks. 

Remember, it's always better to underwater than overwater your string of watermelon. If in doubt, it's safer to wait a little longer between waterings. 

Light Requirement 

When grown indoors, the string of watermelon thrives in bright, indirect light. Place it near a window that receives bright, filtered sunlight for a few hours a day. Avoid exposing the leaves to direct sunlight because it can scorch them. 

For outdoors cultivation, it can handle more direct sunlight. However, it's still best to provide it with partial shade during the hottest parts of the day, especially in regions with intense sun. Morning or late afternoon sun is ideal, as it gives the plant the light it needs without the risk of burning the leaves. 

When transitioning your string of watermelon from indoor to outdoor or vice versa, it's important to acclimate it gradually to prevent shock. Start by placing it in a slightly shadier spot for a few hours a day, then gradually increase its exposure to brighter light over the course of a week or two. 

Remember, the string of watermelon can adapt to different light conditions, but it generally prefers bright, indirect light indoors and partial shade with some direct sunlight outdoors. Observing the plant's response to light and adjusting accordingly will help it thrive. 

Optimal Soil & Fertilizer 

The string of watermelon plants favors very airy, sandy soil that drains well. Planting them in ordinary soil will result in compacted roots, stunted growth, and most likely root rot. Instead, make or buy a well-draining potting mix, or ideally use our specialized succulent potting mix that contains 5 natural substrates and mycorrhizae to promote the development of a strong root system that helps your succulent to thrive. 

The string of watermelon is a relatively low-maintenance plant when it comes to fertilizing. During the growing season in the spring, you can feed it with a balanced (5-10-5), water-soluble NPK fertilizer diluted to half strength. Apply the fertilizer once a year to provide the necessary nutrients for healthy growth. 

When applying fertilizer, make sure to water the plant thoroughly first. Then, dilute the fertilizer according to the instructions and apply it to the soil around the base of the plant. Avoid getting the fertilizer on the leaves, as it can cause burns. 

Remember, it's always better to under-fertilize than over-fertilize your string of watermelon. Too much fertilizer can lead to excessive growth and weak stems. Always follow the instructions on the fertilizer package and adjust the frequency of application based on the plant's response. 

Hardiness Zone & More 

When growing indoors, the string of watermelon prefers temperatures between 60°F and 75°F. It can tolerate slightly cooler temperatures during the winter months as long as it's not exposed to frost or freezing conditions. The string of watermelon appreciates moderate to high humidity levels. You can boost humidity by placing a tray filled with water near the plant or using a humidifier. Misting the leaves occasionally can also help provide some humidity. 

When grown outdoors, the string of watermelon thrives in hardiness zones 9 to 11, which are regions with milder climates. These zones generally have average minimum temperatures ranging from 20°F to 40°F. 

The string of watermelon succulents appreciates moderate humidity levels outdoors as well. In regions with naturally higher humidity, the plant can thrive. However, if you live in a drier climate, you can increase humidity by misting the leaves or placing a humidity tray nearby. 

Final Thoughts

Overall, the string of watermelon is a charming and unique plant that brings a touch of whimsy to any space. With its trailing stems and bead-like leaves resembling watermelons or pearls, it's a real eye-catcher. This low-maintenance succulent is perfect for hanging baskets or as a trailing accent in pots. While its small, daisy-like flowers are less significant, the focus is truly on its stunning foliage. Propagating the string of watermelon through stem cuttings is also relatively easy. It requires plenty of sunlight, well-draining soil, and regular watering to thrive. So, if you're looking for a fun and easy-to-care-for plant that adds a pop of green to your surroundings, the string of watermelon is a fantastic choice.

This stuff just works! Very impressed. If you have a slow leak, get this!
Size: 20oz
This is the second time I've bought this product. I bought one initially to test it out and I was very impressed! I had put some used tires on some used rims for my side by side and I had a couple of them leaking slowly from the side of the rim. I put this stuff in, following the directions and have no more leaks! It's been about a week with the first one, and zero loss in air pressure. I took my side by side out on the trails and thrashed around a bit, still no leaks! This stuff is legit! It comes with a valve removal tool and red valve stem covers to show you which tires you've added this too. Very easy to use, no issues whatsoever. Saves you money having to take your tires somewhere to have them look at them.

This stuff worked better than I thought it would
Size: 40oz
As my title says, this stuff worked better than I thought it would. In fact it worked so well today I will be ordering more. I say today because how can you tell if something like this is actually working... never getting a flat for years? In other words, if it fixes a flat before your eyes it works, otherwise you really don't know. See I had a lawn mower tractor that developed a real bad tire leak a couple of days ago. The way it happened was I cut a Russian Olive tree down, if you know what one of these trees are like, you already know why I got such a bad leak. These darn things have thorns that can get to be almost as big around as a pencil, and are just as sharp as a needle. Moreover, these spikes as I call them, can get to be 3" to 4" long. In short, if you run over one you will have a flat tire, period. That is unless you have this stuff inside the tire already. To make matters worse, if you run over a branch from this tree, you won't only get one or two thorns/spikes stuck in your tire, because as you drive the branch bends easily (only the spike are ridged), so before you know it you will end up with a half dozen of these spikes all the way around your tire, as if the whole tire has a new tread made up of a Russian Olive tree branch. Trust me on this, it will happen just like this. After pulling a half dozen 2" to 4" inch spikes out of the tire, I knew if I took it to a shop they would require me to put a tube in. With this inflation that isn't supposed to be an inflation going on, I'm sure it has made tire tubes today cost almost as much as the whole tire cost me just a couple of years ago. So I thought I'd put this product to a real test... I already have some in my John Deere 2305 tractor. Honestly, it shocked me how quick it worked. It worked so fast I didn't even need to add anymore air to the tire, because all the holes were shut. Pretty amazing stuff if you ask me! I followed the directions, they were easy to follow and the process was easy too. I removed the valve stem, put in 5 ounces of the solution, then put the valve stem back in, aired up the tire and it was instantly fixed... amazing, especially considering why the tire was flat... I should have taken a pic of the spikes. I did roll the tire around a bit, then mounted the tire back on the tractor and went right over and mowed my elderly neighbors lawn, so it got plenty of rotation time. That was about 4 hours ago and the tire is still rock hard. Like I said, I'm ordering more because after seeing this everything we have that runs slow will have this stuff in the tires! Oh, one other thing. The fix-it flat stuff in a spray can, DO NOT USE IT for applications like this! Because that stuff if left inside will actually glue your tire to the rim. Tires have been ruined trying to pry them away from the rim after putting in fix-a-flat, or whatever that crap is called. Sadly this "TireJect" is not recommended for high speed travel, it will through your tire out of balance. So use the fix-flat stuff in an emergency, carry one in your car just in case. Just make sure once you get the tire fixed wash the tire out real good before remounting it. I have never written such a long review in my life, but if you got through it I hope it helped. It's not often a product lives up to it's claims today, but this one in my opinion surpasses it, so I felt the need to say something. Besides, the warning about the Russian Olive tree just may save someone a lot of frustrations.

SEEMS TO WORK WELL... IF YOU CAN GET IT INTO THE TIRE
Size: 10oz, Size: 10oz
The front 11x6 tires of our Scag ZTR mower leaked air around the bead (a common problem). I bought one 10-oz bag to treat them, for about $22. No matter how much I squeezed and squeezed, it would not dispense product. Turns out a small plug of "something" had clogged the hole in the cap (see photo). This might not be a problem for the syringe version but it sure was with the bag. After discarding about an ounce of product and clearing the hole with a finishing nail, I was able to treat both tires. I drove the mower for ~15 minutes. Four days later they seem to be holding air. Previously, they went flat in two days. So it seems to be working, but I have to drop a star for a flawed delivery system. If the tires start going flat again within an unreasonable period of time I'll come back and update this report.

Fan For Life!
Size: Gallon
I would not expect this to seal sidewall penetration or save an old tire from dry rot, but when it comes to road surface tire penetration there is absolutely no better or faster way to repair a flat. 1. You don’t have to remove the tire from the vehicle. Losing half a day waiting for a fixed flat tire is at an end! 2. While a bit pricey, it comes out to be a bit cheaper than a shop trip for smaller UTV or mower tires and A LOT cheaper for larger truck and tractor tires. In 2024, we spent over $350 on flats. 3. We have spiny honey locust trees and bushes invading our farm and deal with flats at least once a month, usually more often than that when clearing fence lines and trees or maintaining pastures. Not to mention the aggravating repeated flats on the same tire are gone. 4. The injector is a bit messy, but the residue will wash off in water if it is cleaned before it dries. 5. So far of the six treated tires on various machines, we’ve had no repeat flats or leaks. 6. Red valve covers come with the packaging so it’s easy to see whether a tire has been treated. 7. This works on tubes and no tubed tires. 8. I’ve used this on my truck, SUV, riding mower, UTV, tractor front tires, and backhoe front tires. Works as promised every time. If the manufacturer is reading this review, I would appreciate a simpler dosing and injection system - especially on the gallon jug. I’m thinking of something like the pump on a lotion bottle where one pump equals one ounce for example. And provide more than one injector hose. Attach a string or other keeper on the valve removal tool. Losing this tiny tool would make the whole system inoperative. Overall, I’m a lifetime fan.
