| Hello, We used to have a large rubber plant that grew the size of a Christmas tree and never showed any signs of disease, but became too large for the room. We took around 30 cuttings from it, but only 2 have survived. Now, the leaves have started developing scratch-looking lines which then turn into cracks. We have not noticed any insects near the plants and we don't have pets. The plant still looks green and healthy. Plant location and watering pattern have stayed the same. What is causing this issue and how do we keep our plant from dying? Many thanks! P.S. Struggling to attach images to my post, for some reason. |

| I don't know how you attempted to propagate the cuttings, so I cannot help you with that although rubber plants are reasonably easy to propagate if done properly. The scratches appear to be some kind of physical damage. They are not from a disease or pest. As long as new leaves are healthy, I don't think you have a problem.

| Thank you for your reply. The plant has been growing fine for over a year and has not been moved or dropped, scratches only started appearing recently. Every leaf is now developing them. Apart from it being unsightly, I just want to make sure, is there nothing I should spray the leaves with? Thanks! |

| It's very odd. It is not a pest so spraying will do no good. It is something physical. Has it experienced any temperature extremes or a lot of direct sunlight?

| Hi WillC, The plant belongs to a relative, I will take another photo when visit them in the next couple of days, there are several leaves with holes where the scratches/cracks first appeared. The temperature inside the home can get down to 15 deg Celsius during the day when the relative is at work and then heats up to 20-21 deg in the late afternoon/evening. We started wondering about the possible temperature effect on the plant, but then again, the temperature has been fluctuating like that since the plant was first potted up, and the parent plant thrived in that home. We are in Scotland, so there is not much bright sunlight throughout the year where the pot is located away from the windowsill. I have thought of more information, if it's of any help. This plant was taken as a cutting and planted three years ago (I initially thought it was more recent), has not been repotted since. It's in the general purpose compost mix and gets general purpose type of liquid fertiliser throughout the year (apart from winter) once a week. It's watered when soil feels dry, roughly once a week. Thanks for reading my posts. |

| The temperature range you mentioned is not a problem for a Rubber Plant. The light could be a problem, however, especially if the plant is not very close to and in front of the window. Allow the top inch or so of soil to dry before watering. If you post a photo that shows the entire plant, including its pot, it might reveal more information about it.

| I will take and post a photo in the next few days when I go over for a visit. Thanks! |
