Thereafter you simply have to rub the pollen with the brush on another flower and the pollinator is done. Once the pollination is complete, they would produce black seeds.

Once the fertilization takes place, the offspring would be different from their parents. Further the female flowers would also become seed pods and they would be green or red in color.

Croton plants would prefer to have bloom boosters and they would be quite beneficial in producing healthy and sustained flowers especially when they are in their latter part of the development stage. That said, you need to ensure that you are providing the favorable conditions for them to produce flowers too.

If I briefly explain, croton plants need to have indirect sunlight for about 6 to 8 hours. If you grow them indoors and if the plants are lacking ample sunlight, you could consider making use of grow lights to supplement sunlight.

Temperature wise, a temperature around 80 degrees Fahrenheit or a temperature slightly below that that would work well with these plants.

When it comes to watering, best would be to water them once every 3-7 days during summer and spring. However, you need to ascertain whether the top layer of the soil is dry and proceed with watering. Lastly you need to provide a soil mix which is fast draining.

The right ph. the level of the soil mix should be acidic . In fact, a ph. range between 4.5 to 6.5 would be ideal. If I further elaborate on the right soil mix, it has to be ideally a mix of 50 % peat moss, 25 % perlite, 10 % sandy soil, 5 % lime and 10 % compost.

In addition to aforesaid, you need to feed them preferably with an acidifying fertilizer which has a NPK ratio of 3-1-2. You need to fertilize them during summer and spring. Many people tend to use ground coffee soaked with water as well.

Croton plants are used to flower in tropical conditions. Hence you need to ideally provide high humidity levels when you cultivate them as well. To be more precise a humidity level around 50 and 80 would be perfect for them.

In addition to the above, you need to watch out for insects such as spiders, thrips, and aphids as they may tend to infect the plants if they feel welcome towards them. Thus, make sure that you monitor the plants well and see whether you could spot any early signs of pest’s infestations.

Croton plants are used to grow in semi tropical conditions. As such you need to provide them with moderate humidity levels to grow well. In this context I recommend you mist the plants or place the pots on trays where you have filled them with wet pebbles.

This would be a fine thing to practice if there are low humidity levels especially due to air conditioning. When you grow them outdoors you could spray the plants with tepid water. Alternatively you could be tactful in placing the plants near swimming pools, ponds and streams as well.

Water and Fertilizer requirement of the croton plants

Croton plants would grow optimally if you keep them moist all the time. So, if you keep growing the plants in dry conditions, it would be harmful for the plants. On the other hand, you should refrain from keeping the plants exposed to waterlogged and soggy growing conditions as well.

So, when you grow them outdoors, I urge you to keep an organic mulch layer as that would keep the soil moist. Besides, it would be healthy for the croton plant’s roots as well.

Fertilizing wise, you need to feed these plants once a week during their growing season. Avoid watering and feeding these plants during winter as then it would allow them to relax during these periods. A balanced fertilizer would be ideal on these plants.

Furthermore, you may also use an azaleas acid formula fertilizer which you could use on these plants occasionally.

Pot requirement of the croton plants

Croton plants would usually grow upright. As such it would make them become top heavy as they grow to their full potential. So, you need to choose a pot which can retain the plants without toppling when they are mature and large.
