Unidentified tree/ problem on the leaves

[Jorgina]

Hello! I have a new tree, it got very sick in 2 weeks. All the leaves seem to be sad, pointing down and some leaves have very small black dots that weren’t there before, i also see some leaves getting dry.
Does someone know what is happening and what could i do?
Does someone know which kind of tree is this one?

Thank you very much

Your tree has very large compound leaves. Initially I thought it may be an Australian native - Grevillea robusta but I looked closer at the leaves and they don't look quite right so now I'm not sure.
ID is sometimes easier if we know what part of the world you are in. You can add a general location to your personal profile so it pops up each time you post and alerts other members to what time of year and what climate you have.

Without knowing much more about the tree and how you have cared for it we can only make wild guesses about what's going wrong.
My first guess is that you are keeping the tree indoors. Only a very few species can cope with indoor conditions - lack of sun and fresh air. Some last longer, some only survive a few weeks or months.
Second guess is watering. Too much water can kill the roots and then the leaves and branches droop and turn yellow. This usually takes a little longer than a couple of weeks but is a very real problem and usually worse indoors.
Conversely, not enough water can cause similar symptoms but much quicker. Some new bonsai owners think just misting the leaves is enough to water the tree but it is a living plant and the roots really need some water too. How much and how often depends on many factors including your location and current seasonal and temperature factors.
Pests can also cause leaves to fade and droop. Mites are very small and often not noticed until too late. They also thrive indoors and can quickly multiply to the point of killing the host tree. The close up shot of the leaf shows pale, transparent areas that may be one symptom of mite damage. Take a really close look for very tiny creatures, especially on the back of the leaves. or tap a leaf over a piece of white paper and then look for moving dots on the paper.

Any extra info about location, where you got this plant, where it now lives and how you have cared for it will help with both ID and diagnosis of the problem.

Thank you very much!! I learned a lot from your message. I inmediately took the tree outdoors and i took some more pictures of the small insects and leaves, the tree and me live in Belgium . I have been watering it for 2-3 minutes every 3 days( when the soil started to dry) till some water would drop in the underplate, also sprayed moist in the leaves. The room where it was had a lot of light but indeed maybe not of ventilation or humidity.

The photo is not enough detail to identify the pest that seems to be causing trouble for your tree. maybe you have a plant nursery nearby where you can take the tree for more accurate ID and help with treating these pests. They may also be able to help ID the tree.

The room where it was had a lot of light

We all think this but we (humans) are creatures of caves and forest. Most trees are from the open and are adapted to full sun. What we see as good light is still very dark for a tree.

I have been watering it for 2-3 minutes every 3 days( when the soil started to dry) till some water would drop in the underplate, also sprayed moist in the leaves.

This is almost OK, depending how warm the room is and what sort of soil the tree is in.
It is good practice to allow the soil to get close to dry before watering but it is also good to properly wet the soil when you do water.
Some soils need more water to make sure it penetrates deep into the roots. Often a small amount of water for a short time only wets the outside of the root ball. Dry soil can be hydrophobic (very hard to wet again). The first water runs around the soil and straight out the bottom of the pot without wetting the soil or the roots so water coming out the bottom of the pot is not a good indicator of good watering. More water gradually soaks into the soil. Some growers water 2 or 3 times a few minutes apart to allow the water to soak in better.
Water moving through the soil also helps push out old air and pulls in new air as it drains through. Fresh air is important to roots so good watering is important not just for the water.
While you get used to how much and how often to water it can be good to soak the whole pot in water for a few minutes each week or 2. This makes sure the soil is fully wet at least occasionally. Having properly wet soil will help the next watering to soak in better and can let the tree drink enough water to get through some dry times if you don't water properly the next couple of times.

If you look at the whitish leaves, you can probably find something that looks like spiderwebs, these are caused by spider mites (spint in dutch).
That, or thrips seems to be an issue.
Luckily, Belgium is easy on the insecticides. Karate Compo / Combo should kill the mites and thrips with two treatments. Do this outdoors though, the stuff isn't allowed in our country anymore because it can damage humans!

Bug attacks like these happens in dry environments, like indoors. Getting the plant outdoors is a good start, if you are getting as much rain as we do, there's no need for outdoor protection.

Treating for bugs will cause the problem to stop expanding, but it will not cure damaged leaves. Good light and watering are best if you want it to recover fast, so stick with what Shibui is saying.
