Has my Bonsai Died? Im worried.

I purchased a Bonsai last December. It was kept indoors over the winter months - in a southerly facing window away from heat sources. Watered as instructed & fed as required.

The leaves shed around April. The tree looked in good health.

It was repotted around April/May time. Using Bonsai Soil Premium Mix - B: 2 from a well known site.

Recently the tree looked dry. So was placed outside to get some natural sunlight and rain water. It has not improved.

See photos attached. These are from today. The Bonsai looks very much dead. Is this the case? Does anyone have any advice?

I have repotted again. And hope this will assist as the roots were dry and water seemed to just pass through the pot.

Thanks in advance.

I think that is dead and has been since it dropped leaves in April.

This plant is dead, and from the looks of it, quite some time already.,

Thanks. As feared.

The delivery note showed different stages of the bonsai cycle. Ours had "mature" ticked. The next being dormancy where the leaves shed.

I will add that after the leaves shed they returned slightly lighter shades of green. THEN they went completely.

I wonder what i did wrong?

There is no bonsai cycle it is a tree cycle. Depending on what species it was it is possible it should have been kept outside not in.
