Croton is a tropical plant with colorful variegated foliage and nearly limitless leaf forms with hundreds of croton plant varieties. Croton plants grow best outdoors in warm, humid climates with full to dappled light in soil on the acidic side and with temperatures above 60 degrees Fahrenheit. Outdoor croton plants can reach around 8 feet tall but houseplants are much smaller. However, be careful about where you plant as crotons are toxic to humans and animals.
The banana croton, also known as the banana plant croton or Codiaeum variegatum, is a popular ornamental plant known for its lush, tropical foliage As a fast-growing plant, the banana croton goes through several distinct growth phases during its lifecycle In this guide, we’ll break down the various stages of banana croton plant growth and tips for optimal development.
Seedling Stage
Banana croton plants grown from seed start off as a small seedling The seedling emerges with two oval-shaped cotyledon leaves As the main stem and roots establish, the seedling will form 4-6 new leaves. Proper care like warmth, moisture, and light is crucial during this vulnerable stage. The seedling stage lasts around 4-6 weeks.
Tips for this stage
- Keep seedlings in bright, indirect light.
- Maintain even moisture in the soil.
- Use a heat mat to provide consistent warmth.
- Pot up seedlings once the roots fill the starter cell.
Juvenile Stage
The juvenile stage begins once the seedling matures and lasts up to 6 months. This is an important developmental period where the young banana croton grows quickly and forms its first true leaves. These leaves will be unlobed and have little variegation.
You’ll see rapid increases in height during this stage, sometimes up to several inches per month. Providing optimal conditions and fertilizer will ensure vigorous growth. As the stem lengthens, additional leaves will unfurl.
Tips for the juvenile stage:
- Give plenty of bright, indirect sunlight.
- Use a balanced liquid fertilizer to encourage growth.
- Maintain moist but not soggy soil.
- Provide a humidity tray for added moisture.
- Stake the stem if needed for support.
Adult Vegetative Stage
The adult vegetative stage starts once the banana croton matures, after about 6-12 months of growth. Growth slows from the rapid juvenile phase but the plant continues increasing in size.
This is when the iconic banana croton leaves reach their mature form – elegantly lobed with dramatic variegated coloration. The plant will readily sprout new leaves and branches during this phase. You can propagate new plants by taking cuttings during the adult stage.
Tips for this stage:
- Give bright, indirect light to bring out leaf colors.
- Prune or pinch stems to encourage bushy growth.
- Feed monthly with a balanced fertilizer.
- Mist leaves regularly to boost humidity.
- Repot annually in spring into a slightly larger container.
Flowering Stage
Banana croton plants may produce small, insignificant greenish flowers during the adult stage, generally in late winter or spring. The flowers emerge at the ends of the stems on mature growth. Flowering is sporadic and not essential to the health or propagation of these plants.
If your croton does bloom, prune off spent flowers to encourage the energy to go into foliage growth instead. No specific care is needed during the brief flowering stage.
Maturation Stage
After several years of cultivation, banana croton plants will reach their maximum mature size and growth begins to slow. The plant may start to look overgrown or leggy. Leaves stay primarily green with less dramatic variegation.
To rejuvenate an overmature croton, you can:
- Severely prune back long stems.
- Propagate younger cuttings to start new plants.
- Repot into fresh soil to encourage new growth.
- Move to a sunnier location to boost foliage colors.
Senescence Stage
In the final life stage, banana croton plants enter a decline as lower leaves yellow and drop. Growth comes to a halt and the remaining foliage loses its luster. Plants generally live 3-5 years indoors but can start to decline beyond this age.
Troubleshooting for a declining croton:
- Rule out usual causes like pests, diseases, underwatering, or low light.
- Prune back stems to rejuvenate.
- Propagate and replace with younger starters.
- Provide optimal fertilization and care.
Understanding the growth timeline of the banana croton enables you to provide tailored care at each stage for optimal health and development. Pay close attention during the seedling and juvenile phases when plants are most vulnerable. Mature banana crotons are resilient easy-care houseplants, but they eventually start to deteriorate as they near their natural lifespan. With the right care and maintenance, you can enjoy the bold colors and tropical flair of the banana croton for years to come.
Propagating Croton Plants
Crotons do not grow well from seed, as the plant is unstable and the offspring wont resemble the parent. Instead, propagate croton plants by stem cuttings or “sports.” Stem cuttings will encourage new growth and control the size of the plant. In addition, crotons sometimes produce sports, or shoots, that are entirely different from the parent plant. These offshoots can be potted up independently but only cuttings reproduce a plant identical to the parent. However, the process for propagation is the same.
In tropical locales where the temperature remains consistently in the 70 to 80 degree Fahrenheit range, you can propagate croton plants year-round outdoors. Similarly, you can propagate crotons indoors or in a greenhouse if you can maintain the same temperature range.
- Use sterile pruners, well-draining commercial potting soil (sand, peat moss, and a vermiculite mixture), a growing pot, and rooting hormone (optional). You do not need a pot if you plant directly in the ground in tropical environments.
- Using sharp, clean pruning shears, cut a 4- to 6-inch stem with the circumference of a pencil at a 45-degree angle right above a leaf node. The cutting should have at least three leaves.
- Use a rooting hormone on your stems cut ends to increase the odds of rooting success. Plant the cutting in moistened soil about 1 to 1 1/2 inches deep.
- Put the plant in a warm, sunny spot away from cold drafts. Keep the soil moist but not soggy. You can enclose the pot in a clear plastic bag to create a greenhouse atmosphere to increase rooting success. After one week, remove the plastic bag.
- Roots should develop in four weeks. If you notice new growth, the plant has rooted. You can also test rooting by giving the cutting a gentle tug. If it feels taut, it has set roots. Once a plant has rooted, its ready for transplanting to a larger pot or a spot in the ground.
- Transfer cuttings indoors anytime but outdoors or in a greenhouse, the temperature must remain consistently around 70 to 80 degrees Fahrenheit for successful transplanting.
Fertilizer
Apply slow-release pellets three times per growing season: early spring, midsummer, and early fall. Or you can use a liquid fertilizer every other month during the growing season from early March to the end of September. Because fertilizers vary widely by type, read the package instructions for feeding quantity. In most cases, if you intend to feed on a regular schedule, you can reduce the package-suggested amount by half strength. Then, observe the plants growth rate over the next month; you can adjust and add or reduce fertilizer depending on how vigorously you want your plants to grow. Stop giving fertilizer during the winter months.
Because this plant prefers slightly acidic soil, use acidifying fertilizers that contain ammonium nitrate, ammonium sulfate, or sulfur-coated urea. Your best target NPK ratios are 3-1-2 and 8-2-10 (nitrogen-phosphorus-potassium).
