Same as your Lantana. It needs to be outdoors in a well draining mix. It has insufficient light.

The same goes for my gardina. I know it's the ph level. It's reading an 8.

A pH of 8 is quite high for potting soil. Which ingredients did you mix to get that? There's ways of reducing pH but in a pot it can be a delicate balancing act as there is very little soil to act as a buffer.

I used Miracle-Gro potting soil and an acidic fertilizer. I did switch to distilled water a couple of weeks ago. Before that I used a hose.

Ordinarily potting soil should be around pH 6.5 to 7, and with an acidic fertiliser it should go a bit lower. What do you use to check the pH?

A thermometer that tells you the moisture level and the pH level.

My lantana is coming back now that the shock of transplanting it. My gardenia since I transplanted it, is showing small green leaf growth. Should I ignore the pH level? What should I do with all the brown hard leaves and buds pluck them off or leave them be? Tomorrow I'll take a picture of my gardenia to show what it looks like I won't get home tonight till after 9pm.

I haven't seen a thermometer with the extra moisture and pH measuring capabilities. Years back I bought a pH meter and it kept giving me a reading of 7. So I finally tried it in wood ash and it still gave a reading of 7. A reading above 10 would have been a little more realistic. The one I have now can be calibrated and I have solutions of various pH value that I can use for recalibration.

I rinse out the tea pot and use that water for plants that like it more acid. It seems to work well. Elemental sulphur is often used but it's initially slow to react and then hard to control. My advice would be to leave the leaves until you get a decent lot of new growth.

I have to try that. I'm a coffee drinker would that also work or just tea? It looks like it's trying to come back. Any ideas how to help it out? Should I fertilize it? I transplanted it about a week or 2 ago. Any advice on what to do when I bring it in the house for the winter? It's just around the corner here. I took a picture of both my meters one reads a 7 the other reads an 8. After what you said I stuck both in my gardina tree. They gave me 2 different readings. Thank you so much for helping with my tree.

I've found that the degree of accuracy of pH meters is directly related to their price. You should be able to get some litmus paper which shows pH by the colour it changes to on contact. You can also get a litmus solution. The test needs to be done in water. It's good to test the water first to see what its pH is, then mix some soil with the water and test that. If the test comes out different to either or both of your meters you might as well throw them out. You could, however, test them on some household products. Check this site, if you scroll down below all the scientific jargon there's a list of common things and their pH values. It lists pH of black coffee as 5. The list will allow you to see how accurate your meters are.

While the plant is weak I wouldn't give it any fertiliser. But watering it with the diluted coffee should be good for it. Some people sprinkle coffee grinds around plants. Water passing through it would become acidic.

Thank you so much you have been very helpful.

I use this meter and it works perfectly. You test the excess water that has run through your soil. I commonly have to mix my nutes and or water to 4.5 to get a runoff of 6.5. You just have to get used to what you need depending on your soil. But I really think you need more light and less watering.
