How To Plant Siam Tulip Bulbs

Rhizomes should be planted in the ground in the spring for growing Siam tulips outside. These plants prefer an organic, humus-like soil that drains well. Use a container with drainage holes when growing Siam tulips indoors. Additionally, drainage can be improved by adding a layer of rocks or pebbles to the bottom.

When caring for siam tulips, it’s important to maintain the soil just barely damp at all times, but never let the roots linger in waterlogged ground.

The Siam tulip should be placed in an area that receives a lot of bright, indirect light and where the sun won’t directly contact the leaves. Several hours a day of additional lighting under fluorescent lamps may be part of the care of Siam tulips. When growing Siam tulips, the appropriate light stimulates the plant to bloom.

Siam tulips last how long?

Specimens kept in excessively dark conditions with extended soil wetness frequently get root rot. Rapid leaf yellowing, moldy soil, stunted growth, and a rotten collapsed base are all symptoms. Examine the plant’s health below the compost line after removing it from the pot. You’re okay to go if the roots have a yellow tint, but you need to take fast action with brown and mushy roots. On this link, you may find more details about controlling root rot.

Your Tulip’s life could end if it experiences basal collapse. A successful specimen’s lifeline is its rhizomes, which are found below the soil’s surface and function like modified stems; any rot problems will result in the plant’s immediate death. Take the plant out of the pot and look at the roots if yours has issues with this. Remove any decaying sections by pruning, and look for a softer profile at the base. Repot any healthy plants in a new batch of “Houseplant” compost and get rid of any individual plants with rotten bottoms. To prevent additional decay, provide a brighter environment and slightly fewer waters. If there are no signs of health below the soil level, discard the plant.

The vines will be encouraged to grow little or no juvenile leaves in a dark environment (shelves, etc.), producing the appearance of ‘leggy’ or naked growth. Additionally, the distance between the nodes will increase significantly, capturing less energy that can be transformed into sortable sugars. Make sure to slightly increase the quantity of indirect light and to gently supplement the specimen with feed labeled “Houseplant” to help it use its stored energy.

Pest infestations can start in the original nursery or through household contamination, and they might appear at any time.

The typical residents are spider mites and mealybugs, with the first being tiny and nearly transparent and scouring the leaves for chlorophyll and a place to bury its eggs. The latter, however, will be considerably more noticeable as white cottony webs form on the stems and foliage. Before giving the plant the all-clear, thoroughly inspect its cubbyholes. You can also learn more about resolving these problems by clicking on the relevant links.

Under-watering and probably too much sunlight are represented by curling leaves with crispy brown edges. Siam tulips frequently have large root systems, so you might want to think about transplanting one to replace some of the existing waters with moister, new soil. For more information, continue reading under “Repotting”!

Leaf Shine shouldn’t be used to enhance the appearance of the foliage because the species is sensitive to chemicals. Instead, the foliage should be washed with a lukewarm water rinse. Failure to do so could result in areas that are mottled and yellow that cannot be removed.

An insufficient dormancy period, where the temperatures are maintained roughly constant throughout the year, prevents flowers from blooming. To ensure a well-spent dormancy, lower the temperature by a few degrees over the autumn and winter months and use fewer irrigations. The natural temperature will start to rise as spring approaches, making this the ideal time to boost irrigation and fertilization. Remember that a specimen is more likely to reflower the warmer the summer days are.


The Zingiberales order, which also includes the genera Musa (banana palms), Strelitzia (Bird of Paradise), and Calathea, contains plants like Siam Tulips or C. Alismatifolia. These plants share a great deal in common with one another in terms of their rhizomatous and stem architecture. Siam tulips were first described by Carl Linnaeus in the 1750s and are native to Thailand, Cambodia, and Laos. The word “curcuma” comes from the Sanskrit word “kukuma,” which refers to turmeric, which has been used as a saffron alternative in India for many years. Alismatifolia, which refers to several species that naturally exist near riverbeds, can be translated from ancient Greek as “water plant.”


15 – 24C (64 – 75F). H1a (Hardiness Zone 13) – Year-round indoor or under-glass cultivation is required. Never allow the temperature to fall below 15C (59F), since this could result in irreversible damage like blossom loss, stunted growth, and yellowed or blackened foliage.

Pruning & Maintenance

Remove plant detritus and leaves that are yellowing or dying to promote better growth and enhance the overall appearance. To lower the risk of bacterial and fungal illnesses, pruning must be done using clean shears or scissors. Be careful while making incisions, as too much damage might shock the plant.


Offset Division (Pups) (Easy) – By dividing the basal offsets into separate pots, you can increase the number of plants you have and prevent them from becoming pot-bound. When the pup is taller than 10cm and it is spring or summer, then is the optimal time to divide. To better reach the pup’s base, where its roots will be housed, gently brush away some of the soil. Cut the cord with at least two root strands attached to the base using a clean pair of secateurs or scissors. Place the puppy in a pot that is the right size, has good drainage, and is composted for houseplants. Temperatures over 15C and bright, indirect light would be present at the ideal site (59F). Keep the soil consistently moist, allowing the top third to dry out between irrigations. Using the above care advice, you’ll be able to treat it like a mature specimen after a month or two.


As they mature, Siam Tulips will sprout at the top of each stalk. Towards the end of the summer, the flowering period can extend up to two months, after which the stems begin to die back. As was already said, the majority of the stems will die back over the winter to prepare for the forthcoming spring. Until new nodes start to grow slightly above the soil line, keep the potted rhizomes in a warm, dryish area.


Every two years, repot in the spring using a potting mix labeled “Houseplant” and the next-largest pot with sufficient drainage. Due to the increased risk of root rot and repotting-related problems (such transplant shock), Siam tulips are much better potbound for several years. Only repot if you really must; restricted root growth will also boost the likelihood of blooms. The subsurface growths typically generate deformed plastic pots, therefore a larger pot is not absolutely necessary.

To reduce the chance of transplant shock, water the plant 24 hours before working on the roots. To reduce the risk of overwatering for plants located in darker areas, add more perlite and grit to the pot’s deeper section.

If you’d want a customized tutorial on repotting your houseplant, schedule a 1-on-1 video session with Joe Bagley. The appropriate branded-compost and pot size will be suggested, and a live video call will be made while you transplant the specimen to provide step-by-step instructions and address any other questions.


Small amounts of this herb, which is considered poisonous, may cause nausea, vomiting, and a loss of appetite. Large amounts should be consumed right away; get medical help if you need more information.

How are curcuma bulbs planted?

Plant 2-3 Curcuma plants on its side “beneath the soil’s topsoil. After the initial planting, cover the bulb with soil and water. Till you notice above-ground sprouts, keep the soil dry. Once growth begins, water as usual, ensuring sure the plants receive at least 1 “per week of water.

Can Siam tulips be grown indoors?

The Siam Tulip is a native of Thailand but is not a real tulip; rather, it is related to tropical plants like ginger and shell flowers. Beautiful indoor or annual plant that can also be grown in pots or the garden. The flowers are durable and make wonderful cut flowers.

Basic Care Summary

In organically rich, well-drained soil, plant. Throughout the growing and blooming season, keep the soil wet. Every month, apply a balanced liquid fertilizer. For the finest display, take out faded flowers.

Planting Instructions

If the plant was bought in a pot, it is likely already in good potting soil and needs only watering and care for the time being.

Start with a high-quality, commercial potting soil whether you’re potting a flowering plant to bring inside or give as a gift. These are typically cleaner, pest-free, and lighter in weight than topsoil. Many come with a mild starter fertilizer already mixed in.

Choose a container with a drainage hole or be ready to drill one if there isn’t one already.

Fill the planter with potting soil until it is 2 (5 cm) from the rim to prepare it. Either by hand or with a trowel, make a tiny hole in the ground somewhat bigger than the root ball. Place the plant in the hole and firmly pack earth around the roots, leaving the root ball exposed. When all the plants are in their pots, give them a good start by giving the soil a good soak. Plants perform best when placed in bright areas.

Every two years, repot the plant in the same container or one that is just a little bit bigger than the roots’ diameter.

Watering Instructions

The majority of blooming plants grown in pots demand regularly moist yet draining soil. The blossoms may droop and may die if the soil becomes too dry. Use your finger to feel the soil’s moisture level. It’s time to water if the top 2-4 (5–10 cm) of the soil is dry or the plants are starting to wilt.

If at all possible, provide water at the soil level to prevent wetting the foliage. Until water is dripping from the pot’s base, irrigate the entire soil surface. This suggests that the ground is very damp.

Fertilizing Instructions

There are many different types of fertilizers, including granulated, slow-release, liquid feeds, organic, and synthetic. Choose a product with a nutritional balance intended for leafy plants and decide which application technique is most appropriate for the circumstance.

It’s crucial to follow the instructions on the fertilizer box to decide how much and how frequently to feed plants because too much fertilizer can harm plants.

For container plants, slow-release fertilizers are an excellent, hassle-free option. For the right time and application rates, refer to the product instructions.

Pruning Instructions

As the blooms wilt, remove them. Depending on the type of plant, this may also encourage more flowers by keeping the plant neat. Many flowering plants make lovely houseplants once they have finished blooming. To keep the proper size and shape, be sure to prune the foliage. Regular trimming decreases the need for the plant to build a larger root system and fosters the growth of more side branches and flowers. Given that the roots are in a small area, this is significant.

While some plants may naturally bloom again, others may have extremely particular day duration or temperature requirements. To find out what is necessary to promote future flowering, some research may be required. After the blooms have been enjoyed indoors, some plants, such as bulbs or perennials, can be transformed into magnificent garden additions.

Are Siam tulips replanted each year?

Feed the Siam tulip once a month until October, after which you should stop feeding it and let it lay dormant for the winter. When the plant is not developing, less water is required, but it shouldn’t go completely dry.

During the dormant season, curcuma may lose most of its leaf, but it will grow back in the spring. Remove any damaged or dead leaves.

Repotting is a necessary aspect of Siam tulip maintenance. When a plant seems to have outgrown its pot, change it up one size. Dividing the Siam tulip every few years will result in more plants when grown as a houseplant. Rhizomes should be divided into two-inch (5 cm) portions and planted into fresh containers as part of continuous Siam tulip maintenance.

Get one started as soon as possible now that you know how to grow Siam tulips both inside and outside. In their outdoor zones, local nurseries and the internet both sell plants.

Siam tulips bloom how often?

The majority of Calatheas are cultivated for their exquisite foliage, which frequently features colorful patterns. With its attractive green foliage and light pink blossoms that resemble tulips, the Siam tulip stands out. This adaptable plant is the ideal ground cover for damp, shaded areas of the yard.

From a clumping root plant, the Siam tulip gently spreads and grows to a height of around 2 feet. To make a nice ground cover for a small area, it’s a good idea to stagger the plants about 18 inches apart.

In sandy soil areas, it is advisable to add peat moss to the planting holes because the plants quickly exhibit signs of water stress. Marl and muck soils, which are better at retaining water, should be fine for the plants.

Siam tulip leaves fold up into a sharp V shape, precisely like grass blades in a lawn do during a drought, to signify water stress.

My Siam tulip was initially positioned in a shaded place near the northern tip of my antique rose bed. The plant displayed scorched leaf margins and water stress in May and June as the sun rose nearly above. It is currently growing more successfully after I moved it to a more shaded location. This is undoubtedly a fan of color.

The plant blooms from spring through midwinter, and the delicate pink blooms persist for a long time.

The tulip-shaped, pointy bracts of the blooms are carried above the foliage on stalks. The large, 3-inch-wide blooms create excellent cut flowers that last a week or more. They don’t smell at all.

Following Hurricane Irene’s 20 inches of very heavy rain, the Siam tulip managed to survive beneath 3 feet of water. If cultivated in a shaded area, this is a hardy plant.
