Q: Last summer, I purchased a lovely desert rose shrub. I transplanted it into a terra cotta pot and placed it in a protected location to avoid frost damage. I just realized the sturdy stem is soft and squishy now. What went wrong, and what can I do to prevent this from happening again?
A: The Desert Rose (Adenium obesum) is a lovely and exotic-looking plant that needs very little care. The overall shape is akin to a well-trained bonsai tree, with an expanded trunk base and twisted limbs. Simple five-petaled flowers emerge in many shades of pink, white, red, and yellow in the summer.
In the summer, the Desert Rose thrives in full sun with regular watering. When the temperature drops to 55 degrees or below, you should drastically reduce your watering. It’s best to use a terra cotta pot because it allows water to drain fast. When repotting, use a cactus mix and avoid using a pot that is too large.
If your plant is being watered on a regular basis by seasonal rain, you may wish to relocate it to a dryer place. The plant will rot if the soil is damp for an extended period of time.
Is desert rose an indoor plant?
The plant also likes stable warm temperatures, which is why it is widely grown as an indoor plant in the United States (except for USDA zones 11 and 12). The plant blooms in the summer and produces beautiful pink, rose, or red flowers as well as bright green leaves.
Sunlight
Desert roses require a lot of sunlight, and a lack of light could be the reason why they aren’t flowering. Place the plant where it will receive at least five to six hours of direct sunlight per day, if not more.
Fertilizer
A desert rose doesn’t need much fertilizer, but it does need to be fed on a regular basis to ensure that it gets the nutrients it needs to blossom. Using a balanced, water soluble fertilizer, feed an outdoor plant two or three times during the spring and summer. During the spring and summer, feed indoor Adeniums once a week with a half-strength water-soluble fertilizer.
It may also assist to apply a phosphorus-rich fertilizer or bone meal to induce flowering.
Where should I put my desert rose?
First and foremost, keep in mind that Adenium plants are native to areas with poor, rocky soil and hot, sunny weather. In a location with little light, the plant will not grow in overly damp soil. They are also not frost tolerant and will perish if exposed to the cold. Temperatures below 40 degrees F (4 degrees C) will kill the plant, but temperatures of up to 90 degrees F will make it thrive (32 C.).
Succulents such as desert roses prefer bright light, therefore a southern window exposure will allow them to thrive and bloom. Choose a sunny spot in the garden that is protected from the midday sun, which can scorch the foliage.
The importance of soil cannot be overstated. For adequate drainage, adenium plants should be planted in a mixture of cactus soil and gritty sand or lava rocks.
Why is my desert rose leaves turning yellow and falling off?
Desert Rose is an evergreen tropical shrub. Only USDA hardiness zones 10 through 12 are winter hardy. As a result, it is commonly kept as a houseplant.
The plants’ leaves may turn yellow with leaf drop in autumn when planted outside or in a very chilly location indoors. This indicates that the organism is about to enter a dormant state.
You can choose to keep the Desert Rose alive as a houseplant over the winter or let it fall dormant.
If the plant is in a small container, put it indoors before the weather becomes chilly to avoid yellowing and leaf drop.
Make the decision to keep the plant dormant over the winter. For 3 to 4 months, reduce watering and keep the soil dry (typically between October and February).
During the dormant season, keep plants in a cool (55° to 60° Fahrenheit) low-light environment. In the spring, switch it to a brighter, warmer setting and feed it. It will soon start producing new leaves.
How do I get more leaves on my desert rose?
Because the desert rose is a sun-loving plant, place it in the brightest location possible. It looks great in landscaping beds and borders as well as containers and planters on decks, patios, and other outdoor areas.
For optimal effects, water the desert on a regular basis. The plant can survive in low-water situations, but it will lose some or all of its leaves if it dries out too severely. (Don’t worry if this happens; if it gets adequate water again, your desert rose will grow new leaves.)
If desired, fertilize desert rose with a general-purpose fertilizer in the spring and summer. Follow the directions on the fertilizer package carefully.
It should be noted that desert rose is not suitable for human or animal consumption. This plant is poisonous in all of its components.
Is Epsom salt good for desert roses?
Epsom salts are highly recommended by rose producers in particular. It not only makes the foliage greener and lusher, but it also generates more canes and roses, according to them. To apply Epsom salt to existing rose plants, either mix 1/2 cup of the salts into the soil surrounding the bush and water well, or dissolve 1/2 cup of the salts in water and use to moisten the soil around the rose bush. This is best done in the spring, when the buds are just beginning to open.
Can I use Miracle Grow on desert rose?
I utilize the same starting mix for our plants that will be shipped. I use around a third of a third of a third of a third of a third of a third of a third of a third of a third of a third of a third of a third of a third of a third of a third of a third of a third of a third of Poultry grit is fantastic, but it’s too heavy to send cheaply. I use a commercial mix, Fafard 4P, for the basic mix, but any decent grade potting soil, such as Miracle Grow, Expert, or Jungle Growth, will suffice. To this, add a third of a cup of coarse Perlite by volume.
For permanent plants, this is the final mix…..
2/3 cup beginning mix, 1/3 cup poultry grit Poultry grit is available at any farm supply store. If you can’t obtain poultry grit, aquarium gravel will suffice; however, aquarium gravel is more expensive. If neither poultry grit nor perlite are available, a bag of Lowe’s pea gravel will suffice. You can probably guess where this is headed. Make sure there isn’t any water in the mix. The point is that we make do with what we have. Drainage, drainage, and more drainage come to mind.
To begin, soak your seed overnight. Fill a pot with the basic mix and make sure it has plenty of drain holes. Soak the mixture until it can no longer hold any more water. I use the end of a ball point pen to make the seed holes. Make these holes somewhere between 3/8″ and 1/2″ deep. Fill each hole with a seed and fill with potting soil or sand. To ensure that the mix is in excellent touch with the seed, press it down. Allow the mixture to almost dry before keeping it moist until ready to use.
The seeds germinate. With new seed, sprouts should appear within a week to 10 days.
Adeniums can be fertilized with any excellent garden fertilizer.
We use standard 10-10-10, Miracle Grow, or one of the big box knockoffs depending on what’s available. On some forums, it may be said that Miracle Grow and its knockoffs are ineffective for Desert Roses. Both of them are OK if you don’t anticipate them to work as foliar feeds like they do on other plants. Adeniums’ leaf covering limits uptake as a foliar feed. Instead, apply them to the soil. Organic fertilizer, particularly composted manure and fish emulsion, is also beneficial to adeniums.
Your little plants will let you know when they need to be repotted if they are in thin plastic pots. The plants will either split the pot or at the very least distort it. The underground section of the caudex is growing, which causes this. Raise the caudex about a half inch above the former soil line when transplanting these to larger pots. Trim any fine feeder roots that have been exposed as a result of the elevating. Raising exposes a light-colored ring that will shortly darken to match the remainder of the caudex.
Last but not least, a word on watering. Water is required for adeniums to grow and flower. During the summer growing season, we water ours at least once a week. They get very little water during the winter dormant season, no more than once a month. If the plant receives too much or too little water, the leaves will yellow and fall off. This is merely a desert survival mechanism that has no negative impact on the plant.
How long can a desert rose live?
The desert rose can live for more than 500 years. It has distinguishing qualities that allow it to last for decades. For example, its stem has a bloated base that continues to inflate over time and can grow up to two meters in diameter. The stem stores critical nutrients that the plant uses to nourish the other parts of the plant as the weather changes.
Measure the diameter of the stem to determine the age of a desert rose. Every millimeter symbolizes one year for this slow-growing plant. It’s a seasonal succulent that sheds its leaves when the season isn’t right. Surprisingly, the plant receives sufficient nutrients even when other plants begin to die due to extreme weather conditions.
When should I water my desert rose?
When the earth feels dry, the desert rose merely needs to be watered. It just needs water every three or four weeks in the winter. This causes it to go dormant, allowing it to bloom more abundantly in the spring. In the spring and summer, the desert rose can be fertilized once a month.
