My cheese plant leaves have developed sticky patches and brown dots. Could this be from bugs?
This sounds like scale. The scale is the brown spots and the excrete a substance called honeydew, which is wet and sticky. This article will help you: https://www.gardeningknowhow.com/plant-problems/pests/scale-bug-how-to-control-plant-scale.htm
I have purchased a cheese plant which required repotting as it was root bound. Since repotting about 4 weeks ago, some of the leaves are turning black. Could you give me some advice please?
Some plants go into shock when they are repotted. It sounds like yours has. Make sure that the drainage is good in the new pot and provide a little fertilizer. If you give it good care, it should come out of shock and recover.
I have a large cheese plant in my living room. How often should I water it?
Water your plant whenever it is necessary. The best way to know when it is necessary is to touch the soil. If the plant soil is dry to the touch, then it needs to be watered. Allow the soil to dry out some between waterings.
I have had the plant for 35 years. It has moved home and been repotted many times and always thrived. It has been in its existing location in sunny/shady lounge for 5 years. For the last year it has only had small new leaves but now all of the large leaves are going brown, but the small leaves are still healthy. I have not changed anything about its care. It is due to be repotted.
I suspect it has a fungus. Try treating it with a fungicide.
Need for repotting may also be the issue, but typically if this was the case, you would see problems with new leaves rather than old leaves.
I had what was a healthy cheese plant indoors and during the hot weather this week I put it outside for some sunlight but left it out at night. Now the leaves have gone brown and withered. What can I do to it, chop of the dead leaves, cut it right back?
The plant is simply stressed. You can try cutting out all the brown/dying foliage but leave the green. Make sure that it has plenty of water, as it probably dried out if it was hot, and keep it in a sheltered location (out of direct sunlight/light). It will hopefully bounce back in a few weeks if not sooner.
I have a very old cheese plant, which seems to have lately found a new lease of life and is producing new leaves. However, it is root bound and my cheese plant needs to be repotted into a slightly larger pot. When is it safe for me to do this please?
With almost all houseplants, it is best to repot while they are dormant in the fall and winter. They are less susceptible to transplant shock if they are repotted when not actively growing.
How big is your "cheese plant" ? (I'm guessing this is the type of philodendron often called a swiss cheese plant). Unless it's so big that it's tipping over its pot, it may not need repotted at all - in fact, with new leaves, it may just be getting going. Potted plants fill the pot with roots before they make leaves, so if you had it potted in a great big pot, it could take it several years to grow enough roots, and its just now starting to think of leaves.
I've had a Swiss Cheese plant for about 3 months now. We bought it mature from a garden centre and it seems to be doing really well. There's just one small problem. When a new leaf starts to come out, it comes out black and dry, and then drops off. I was wondering if there was anything I could do for this not to happen! Thanks, Ed
It may need more humidity. A pebble tray filled with water placed under the pot should help.
