How long for orchid to grow new roots, is a popular orchid query, as one would wish to know the right timing for the plant to start growing again. But you must keep in mind that this query is one that depends on two factors, which are the current season and stress.How Long for Orchid To Grow New Roots

Fortunately, you can speed up root development and growth with the right methods, which we have discussed here. Keep reading our article; we have a guide to keep you on track with the details needed to see them grow in the right time range.

How Long for Orchid To Grow New Roots?

Orchids take from two weeks to five weeks to grow new roots. This timeframe depends on the season and whether the plants are under stress. If everything is ideal, you may see a fresh mature root within two weeks, and it will take months in case of unsuitable conditions.

– Growing Phase of Orchids

The time that the plant needs to be able to shoot new roots is a matter that depends on the orchid’s growing phase because there are thousands of orchid species, and each has different season preferences. Most prefer winter and spring, while some can grow roots in summer and fall.

Phalaenopsis orchids, which are the most popular ones, are able to produce new roots in the cold, while dendrobiums grow when the temperature is warm. It is very important for you to learn about the growing season of your orchids and expect root growth during this time.Growing Phase of Orchids

– Unsuitable Conditions or Stress

Stress like low humidity, high or low temperature, and poor ventilation are factors that would easily slow down orchids’ internal and physiological processes. As a result, plants get short on energy, and the time period of their growth is extended, which may also give a stressful result.

Therefore, roots or any growth will happen unlikely. But if these conditions stay optimal, then orchids will produce new roots without a problem.

What Are the Stages of Growth of New Orchid Roots?

The stages of growth of new orchid roots are when the roots first emerge as small bumps, which are red to green in color in most cases. They start to stretch and droop with time, continuing their growth and becoming white to greenish within two to five weeks.

– Small Colored Bumps

When roots start to emerge, they look like small bumps, and it is red to green in color in most cases. In this stage, it isn’t easy to differentiate whether the new growth is a root or a flower spike.

Still, carefully observe the change, because, in this case, you may see the young orchid flower spike is greener than an aerial root. Furthermore, the spike grows toward the sky, because it is the lighting source, while roots start to travel downwards.

– Elongation

After a few days, the aerial roots will stretch and droop downward. Roots in this stage are still being prepared to absorb moisture from the air and offer anchorage benefits.

– Maturation

After a week of initiation, roots mature, if everything stays ideal, and there is no stressor getting in the way. They look white to green in color. Furthermore, they feel firm when you hold them.

How To Help Orchids To Grow Roots Faster?

You can help orchids to grow roots faster by adding water appropriately, providing light for more than 12 hours, and feeding nutrients weekly. Also, ensure the potting medium is healthy. If it isn’t, repot the orchid and apply rooting hormones.

– Add Water Correctly

Dry orchid roots do not grow properly, and keeping this in mind, you should ensure the potting medium stays moist except for cymbidiums and other dry orchids. Consider the potting mix behavior before watering, so that it wouldn’t stress the roots.Watering Orchids Correctly

You should pour water in controlled amounts if the potting medium is sphagnum moss. But if it is bark or any other potting media with poor water absorption, you can put the orchid pot in the water-filled bucket or take it to the kitchen sink and water it there. Furthermore, you can also spray the young aerial roots to speed up growth.

Moreover, always drain out extra liquid as the roots don’t grow in a soggy medium, as most water should seep out from the drainage hole. You can also put a bowl next to the pot and tilt it. If you still see water on the potting mix, use a sponge or soak it up, and in short, when you go ahead and water this way will keep the young roots hydrated and allow them to stretch quickly.

– Maintain Ideal Lighting Conditions

12 to 14 hours of light is critical for smooth root development, and the roots would grow in a healthy situation when the lighting is their favored one, which should be indirect. Orchids use light exposure to make food via photosynthesis, which is then utilized to produce new growth, including beautiful aerial and ground roots.

You should grow orchids near the east-facing windows or doors because morning light enters through them. You can also put them under the shade of any structure outdoors. Keep two things in mind, first to avoid any direct sunlight should fall on the spot, and you must be keen on the air circulation and how it should be optimal, as you will notice the orchid growing new roots in a few days.

– Add Fertilizers at the Right Time

Applying nutrients timely also helps with root growth. In such a case, it is best that you give doses of a balanced fertilizer, which should have a ratio of 20:20:20. You can follow a weekly or monthly fertilization schedule.Adding Fertilizers to Orchids

Fertilizing every week is better because nutrients stay available for them each day without causing fertilizer burn. However, if you can’t follow the weekly schedule, keep giving it in a monthly schedule in a proper amount.

– Ensure the Potting Medium’s pH Stays Suitable

Another critical orchid care that you should never neglect is keeping the pH of the potting medium within the ideal range of 5.5 to 6.5. The reason is that the roots feel uncomfortable when the pH is out of the desirable range. Therefore, you won’t see any considerable growth in such a medium.

Use pH stripes regularly to check the potting medium’s status. If the pH is more than 7.0, you can use a commercially prepared pH-lowering agent. Furthermore, you can also add sulfur, vinegar, and coffee grounds. If the pH is below 5.5, use wood ash, crushed eggshells, and lime to increase it.

– Keep Checking for Drainage and Air Pockets

Poor drainage and restricted oxygen supply can stress young roots and slow or stop their growth. In addition, the roots can also grow upwards and come out of the pots, which is also undesirable.

So, what do you do when orchid roots grow out of pots? We suggest you repot the orchid in a bigger pot. It is better to change the potting medium when you plant the orchid in its new home.

If you wish to have a proper grip on how to repot an orchid with air roots you must begin by getting an inch or two bigger pot than the previous one and fill it with the top-quality mix. Now you should unpot the orchid and remove the sick roots, and soak the roots and trim unhealthy roots again.

Remember to sterilize the air roots with three percent hydrogen peroxide, and aim to put the orchid in the new pot. Ensure the roots spread properly, and cover the roots with a potting mix and pour water. The new potting medium will be fresh, which the roots like, and it will also have better drainage and more air pockets. So, repotting is a solution for many root problems.

– Monitor and Manage Temperature

You should always keep the temperature within the suitable range when growing orchids. Phalaenopsis orchids grow smoothly when the temperature is between 55 and 70 degrees. Depending on the orchids that you have, you should determine the temperature the preferences of other orchid varieties and note them down.

You can deal with high temperatures by watering the orchid more and using fans to cool off the heat. In extreme cold, we recommend you use space heaters or heat lamps. The roots will feel comfortable when you manage the temperature.

– Apply Rooting Hormones

You must also be detailed on how to save orchids with no roots, and this would be with the matter of helping them grow roots quickly. But how to regrow orchid roots has always been tricky. Fortunately, we now have rooting agents that encourage the orchids to promote root initiation and growth.Rooting Hormones for Orchids

However, use the best root stimulator for orchids, so try to check the reviews online before buying one. In addition to this, there are also some natural agents that you can use to promote rooting. The popular ones are honey, aloe vera, and cinnamon powder.

Choose any of these rooting agents and mix them with water. After this, carefully water the orchids. You can go ahead and do this after repotting the orchids as well. These substances influence hormone release, which helps the orchids to produce roots.

– Prune the Roots

Pruning is an excellent strategy to force the orchids to develop new growth, including roots. In this, cut the old and sick parts because they are useless, and so, you can trim discolored aerial roots using sharp pruning scissors. If any roots feel mushy, you should cut them too. Furthermore, are your orchid air roots too long, so then, removing them is the best idea.

You should 100 percent prune the dead roots, but how to tell if orchid roots are dead? They are brown to black. Also, they may feel soggy when you touch them. So, if you see such roots, trim them.

For better results, prune the roots before the start of the growing season. The reason is that the orchid plant will then find it easy to grow new roots that will be healthy and firm.


You can accelerate the root development and growth by doing some things, which are:

  • All-inclusive, roots can take two weeks to five weeks to grow, depending on the growing season and environmental conditions. It is initially a tiny green bump, which elongates into a mature white-to-green root.
  • Add water in the right amounts and drain the extra liquid, so provide light for about 12 to 14 hours a day.
  • Ensure the potting medium is healthy with a pH of 5.5 to 6.5 and has lots of air pockets.
  • Pruning and repotting also encourage roots to start growing.
  • You can also apply commercial or natural rooting agents to fasten up growth.

A stronger root system means a healthy orchid; therefore, help these plants develop roots as they will reward you with vibrant flowers.
