Question 1

What's the best method of watering my Rainbow tree?

Accepted Answer

Misting can be a good way to keep the leaves hydrated but not too soggy. Always make sure that there's good drainage to prevent root rot. The plant can be sensitive to fluoride, which is often common in the public water supply, and this species does not tolerate hard water, especially if it's in its growing stages.

Use a watering can or a sprinkler with purified or distilled water. Make sure to evenly water the entire surface of the soil so the stems won't rot. Use distilled water from time to time to avoid the death of the plant, leaf burn, or stunted growth instead of tap water. Another option is to utilize rainwater whenever it's available. Keep the soil moist every time but prevent it from being too soggy if the Rainbow tree is planted in a pot.

If it's outside planted in your garden, you need to have proper drainage and allow the soil to dry completely before you turn on the sprinkler or the garden hose, as this can lead to root rot and yellowing leaves.

Some use hydrogen peroxide as a treatment in the water, but this is not recommended for regular use. The hydrogen peroxide will stimulate rainwater but only do this occasionally. A filtration system might also be valuable for removing nitrates, salt, and lead that might be contained in the water.

Question 2

What should I do if I water Rainbow tree too much/too little?

Accepted Answer

Some signs that the plants are not getting enough water are the brown tips on the plant. These species are very sensitive to boron and fluoride that are usually found in tap water, and you might be able to see that they have too much of the minerals when the leaves begin to droop.

When the Rainbow tree is underwatered, the stems also show wrinkles.

The leaves can become brown, crispy, and start to dry out. When this happens, water as soon as possible.

Another thing about overwatering is that if this happens, then root rot can begin to set in. You need to remove all the damaged roots from the soil, especially if they appear mushy, fragile, and black. To help with these issues, it's important to cut off a larger part of the root.

Overwatering can also leave the leaves looking brown and ready to fall off. This can happen very early, so you should drain the excess water and wait for the soil to dry before watering to help the plant recover.

Throw away the soil from the pot if there are signs of root rot. Clean everything thoroughly and make sure to put in the pebbles so it will help with proper drainage. Discard any excess water at the base of the pot if you notice tan rings or reddish-brown spots on the leaves.

Question 3

How often should I water my Rainbow tree?

Accepted Answer

The Rainbow tree is a relatively tough species that is pretty tolerant to drought. This is why you need to water this only about every 1-2 weeks when you feel the soil is bone dry, especially if it is planted in a pot. Water generously until you see that the water begins to trickle down the pot's drainage holes. Make sure to remove the water from the saucer after an hour, and don't let it stand on the pot.

When they are planted in your garden, you need to consider the rainfall the plant is receiving. The roots don't like to sit in the water, so make sure to have proper irrigation as part of the landscape. Water 1 time every 2 weeks, especially if you live in a tropical area with plenty of rain and monsoons.

Question 4

How much water does my Rainbow tree need?

Accepted Answer

As a general rule of thumb, you should water Rainbow tree when you notice that about 2 inch of the top soil is already dry, especially when you grow it outdoors. When planted in the garden, you need to make sure that the Rainbow tree is getting its watering needs at least once every two weeks. There’s rainwater, seasonal changes, and moisture around the environment to consider so never overwater.

This can also apply when the pot is approximately 2 inches dry when it is grown indoors. If they are inside the house or grown in the nursery, try watering more frequently at least once a week since they might not be able to get the rainwater or extra moisture that they need indoors. As long as you notice that the plant leaves are sagging, then don’t hesitate to give them a drink.

The roots should be kept moist but not soggy. The best way to water them is to soak the pot and allow the water to drain. Make sure to water only when the soil is partially dry, and don't give them a specific schedule. They are not very thirsty plants, so wait a couple of days before giving them a drink. Well-draining soils can also help them grow and always put them in place with high humidity.

Water them every 1 to 2 weeks during the summer when it’s very hot outside. During the growing season and in spring, use the same amount of water as well. They need a lot of water when they are growing so you might want to give them a drink regularly.

If it’s winter or fall, know that you should only water every 2 to 4 weeks. This is when you notice that the soil is completely dried out.

Question 5

How can I ensure that i'm watering my Rainbow tree adequately?

Accepted Answer

Most of the time, schedules of bi-weekly or weekly watering should be more than enough for the Rainbow tree. Wait until the soil is 2 to 4 inches dry, especially if you have adult plants, to avoid excess watering. Pour generously until you see that the water comes out of the drainage holes. No standing water should be allowed, and remove the excess from the saucers. Root rot can happen if there's too much water, so it's always better to give too little than too much for this species.

The soak and dry method is more than enough for the plants whether they are indoors or outdoors. The soil around the plant should be completely soaked and make sure to record on an app or in your calendar each time you water. Allow the soil to dry to prevent root rot and help them develop a healthier root system. Water with a sprinkle or a can deep enough to reach the roots to prevent the plant from wilting.

Question 6

Should I adjust the watering frequency for my Rainbow tree according to different seasons or climates?

Accepted Answer

The soil bed or the pots should be moist during the spring or fall. However, prevent them from getting soggy. Reduce watering during winter or towards the end of the fall. Remember that soil that's too dry or too wet might result in plant issues.

Allow the Rainbow tree to dry out before watering, especially in the winter. When there's too much dryness in the soil, use distilled water and saturate them thoroughly. Avoid cold water as much as possible. Occasional misting during the summer or the winter, as well as fertilizer in the spring, can help.

Question 7

Should I change the watering frequency during the different growing stages of my Rainbow tree?

Accepted Answer

Water at least twice a week during its growing season, and you'll find that they can grow quicker. When they are in their early stages, the Rainbow tree is very sensitive to the minerals in tap water, so it's best to expose them to rainwater or filtered water.

While they are young, exposure to unnecessary chemicals can result in stunted growth and discoloration. A balanced fertilizer and watering whenever the soil is dry can help during the growing season.

In the growing season, the watering should be 1 to 2 times a week. When it's already established, you might want to water it once every 3 weeks. When you report a grown Rainbow tree, you need to water the soil well to make it damp. You can also wipe the leaves with a wet cloth to keep the insects away and to help them have more humidity during summer.

Question 8

Should I water my Rainbow tree differently when I plant it indoors vs outdoors?

Accepted Answer

Depending on the location of the plants, it's best to water them frequently when they are indoors. Just make sure that they are far away from any heating appliances. The natural humidity of the room can be enough, but the plant might prefer the high humidity outdoors during the summer, especially if it resembles that of a rainforest's habitat.

Water the plants once every two weeks and lightly mist them at least thrice every seven days to keep them healthy if they are planted in a pot. One way of checking it is by removing the pot and seeing if the roots are already dry. This is possible with plastic pots, but you can always check with a moisture meter if you can't remove the pot.

When grown outdoors, you need to consider the plant's rainwater, especially in spring and summer. You might want to water this once every 1-2 weeks during the summer.

Avoid watering this during the late fall and winter, and only provide them a drink when you see brown spots on the leaves. They only need occasional watering when planted in your garden, and you need to transplant them indoors so they can survive the cool conditions during the winter. Some use a lot of mulch during the fall, but when growing in a cold zone, you should consider digging it and transplanting it, watering it occasionally, and waiting for the frost to pass.

Question 9

What should I be careful with when I water my Rainbow tree in different seasons, climates, and during different growing periods?

Accepted Answer

The Rainbow tree loves high humidity and thrive in it. However, winter is when the humidity is low, and the indoor ones are more susceptible to wilting. Lightly mist the leaves with sprays so you can maintain the healthy growth of the plant in the spring and summer. It would also help to place the plants on trays that are filled with water and pebbles to create humidity around the Rainbow tree during winter but make sure to drain the saucer afterwards.

A high-quality humidifier might also help during winter. Also, use cold water on the plants during winter as this can cause permanent damage and root shock. Allow the water to warm at room temperature before you put it on the plants. Using heating appliances can dehydrate indoor air, so you might want to add more mist.

Place the pots near it and let them absorb the mist. Use bottled distilled water whenever possible since these are sensitive to fluoride. When you notice that the tips begin to turn yellow, this is where you might want to do the light misting several times a week.

Another thing is when you're using tap water from the local supply, just let it sit overnight. This will reduce chlorine and other chemicals that might be mixed into the water. Distilled water is always the best alternative.

During the summer, be careful with overwatering. The brown tips suggest that there's not enough moisture in the air, and you should add some when the Rainbow tree shows an indication that it’s thirsty.
