🌸 Adenium Care Basics

Adeniums have many spectacular hybrids, and their basic culture is closer to orchids than to typical houseplants. The key is a small pot, excellent drainage, bright light, and careful watering.

Pot and Soil

  • Use a small pot sized to the root system.
  • Excellent drainage is required.
  • Use a very well-drained mix. We recommend specially formulated for Adeniums Desert Rose Soilless Mix

Light and Blooming

  • Give lots of light for heavy flowering.
  • In warm conditions and longer days, most hybrids and species begin blooming in spring.
  • In warmer climates they can keep blooming through fall and winter.

Watering (Most Important)

  • Adeniums dislike both extremes: over-watering and drying out too often.
  • Use neutral to hard water when possible.
  • Acidic water can sour the mix quickly and may cause root rot.
  • Water in the early morning so the plant can drink through the day.
  • Watering frequency can range from daily to every few days, depending on heat, light, and how fast the mix dries.
  • Never let the pot sit in a saucer of water.
  • Do not let the plant dry out too often, or it may go into early dormancy.
  • Do not wet the leaves.

Fertilizer (Caudex + Flowers)

  • To build a large swollen base/trunk (caudex), use a good quality fertilizer.
  • A fertilizer that helps trunk swelling also supports flowering. The best choice for this is Sunshine Megaflor.
  • Avoid fertilizers that are too high in nitrogen; choose a formula where the middle number is the highest.
  • Never apply fertilizer directly on roots.
  • Do not liquid feed a thirsty plant.
  • Always water lightly first, then feed, to avoid root burn and leaf drop.

The Caudex "Secret" (Shaping the Base)

  • At each repotting, lift the plant slightly so the upper roots are a little exposed.
  • This encourages new roots to grow downward and helps create a thicker, more interesting caudex shape.

Multi-Grafted Plants (Important Note)

  • Adenium hybrids can be multi-grafted with several colors/varieties on the same plant.
  • The swollen base forms only when the rootstock plant is grown from seed.

✍️ Adenium FAQ

How much light do Adeniums need?

Adeniums need lots of light for heavy flowering. Most hybrids and species start blooming when conditions are warm and days get longer, and in warmer climates they can keep blooming through fall and winter.

What is the best pot size for Adeniums?

Use a small pot sized to the root system, with excellent drainage. A small pot with excellent drainage is a must.

What kind of soil mix should I use?

Use only a well-drained mix. Adeniums do best in very well-drained soil. A small pot plus excellent drainage is the foundation of success.

How often should I water Adeniums?

Adeniums do not like both over-watering and drying-out too often. Water preferably in the early morning and do not water again until the mix dries on the surface. Watering can range from daily to every few days depending on heat, light, and how fast the mix dries.

Can Adeniums sit in a saucer of water?

No. Never allow your Adenium to sit in a saucer of water.

Should I wet the leaves when watering?

No. Do not wet the leaves.

What kind of water do Adeniums prefer?

Adeniums prefer neutral to hard water. Acidic water tends to sour the soil too fast and may cause root rot.

How do I create a large, swollen caudex?

At each repotting, lift the plant slightly so the upper parts of the roots are a little exposed. This encourages the plant to form more roots that grow downward and helps create a thicker, more interesting caudex.

What fertilizer should I use for caudex growth and blooms?

Use a good quality fertilizer to support both trunk swelling and flowering. Avoid formulas that are too high in nitrogen; the middle number should be the highest. Never apply fertilizer directly on roots, and do not liquid feed when the plant is thirsty. Water lightly first, then feed, to avoid root burn and leaf drop.

Can an Adenium have multiple flower colors on one plant?

Yes. Adenium hybrids can be multi-grafted with several colors or varieties on the same plant. Note that the swollen base forms only when the rootstock plant is grown from seed.

Soursops fruiting in Virginia?!



Amazing news - from our customer in Virginia. Not only his ultra tropical plants survive - they thrive, producing multiple fruit in only 2 years despite living in a climate with freezing winter temperatures.

We always like to think of our plants as a challenge. We continually push ourselves to collect, grow and propagate the rarest of the rare. Seeds, plants, and cuttings are ordered from all over the world and continue to challenge us with finicky temperature, humidity, and watering demands.

Naturally, we also get many customers from cooler zones asking which plants they can grow. The answer is any of them! As long as you can give them the requirements they need. Continue reading...

Growing fruit trees in containers

Will it fruit in a pot? YES! Many tropical fruit trees can be grown in a pot. We get many calls from customers in cooler climates asking if our tropical trees can grow and fruit in a pot. The answer is yes!

Several plants fruit well in pots. Blackberries and raspberries, barbados cherries, blueberries and many more start fruiting even in their 1 gallon containers. We are especially excited about our new Pixie grapes, which are heavily laden with grapes even at only a foot long!

While some plants are small and will fruit easily in a container, others are large trees. For the tree type fruits, we recommend growing only non-seedling plants for pot culture. We have cuttings, air layers and grafted plants that are great options. These have the ability to fruit right away, as they are the same age as the parent tree. Some horticulturists recommend removing the first year fruit to allow the plant to focus on growth and establishing. If the plant is being kept in a pot, this is not necessary.

We also have several dwarf varieties of fruit trees that will thrive in a pot. For avocados, we carry the Wurtz variety which is a dwarf tree... read more...
