I am trying to maintain a 71/2 Meyer lemon in a container in 7b. I would like to feed it organically and I have recently heard of brewed fungal tea and worm castings tea (and there are many you tube videos that suggest many other additions i.e. Kelp, etc.) I am having leaf curl and a dark midrib and these leaves are falling. I brought the tree 2 months ago so I expected some leaf fall I had a tremendous number of blossoms but they are now all brown and falling off, Im guess that's normal I did some hand pollination but I dont see any baby lemons I would love any advice - thank you !!!
What conditions there are? Heated rooms are often too dry for plants during winter season. And may lack of sunlight.
Thank you so much Sulev, Do you know what the humidity levels should be? I have 3 grow lights on it so I think there is enough light (I dont know how to measure that exactly)
I suppose RH should be around 45% +/- 10% and optimal temperature is +10...+15°C. +25°C and above is not so good for overwintering (because you can't compete with Sun, artificial lighting is usually weaker).. Water evaporates quicker from the warm soil. Plants have more intensive transpiration in case of warm soil.
