Sorry, never heard of it until your post. I looked it up and it sounds like it is a foliar fertilizer spray with micronutrients. I don't know if it is really better than foliar feeding with Foliage Pro or Miracle Gro and if it really does anything to open the plant cells to let in the nutrients better. Seems expensive.

Thanks Cory, from the reviews on you tube and Google they claim it works well but the instructions say to use it in the growing season up until the fourth week of flowering and I'm not sure if that means the whole while the trees are under the grow lights or not, do you? The reviews are not citrus trees though. Yes I think it is expensive too but I had lost four citrus trees a few years ago and I thought I would try anything to make sure that doesn't happen again. I have more knowledge about the citrus trees this time around but not sure if l have enough to keep them going. I guess only time will tell. Cathy MI zone 5

Never heard of it either but the name certainly sounds promising doesn't it? I could always use more light in my grow room! I would be interested too if anyone has tried it.

I think keeping the citrus roots from becoming too wet is the most important. So, the correct open, fast draining mix such as the gritty and 511 is most important. Lots of light and a fertilizer with the correct proportions of n-p-k and micronutrients will bring flowers and fruit when the tree is mature enough. To keep trees growing when in lots of light in the winter the soil in the container needs to be above around 55°F. If you only have low light conditions in the winter, keep your trees semi-dormant by keeping them cooler (45-50°F). Grow trees outside during the spring, summer, and fall as they need the direct sunlight and outdoor humidity. Remember to gradually acclimate them to direct sun over a 2 week period. Test soil moisture with a dowel or pencil before you water. Follow these practices and you will have healthy trees with fruit. Foliage Pro and Osmocote Plus are good fertilizers used very successfully by most members here. I am a container grower, but most of these practices apply to ingrown too.

It is not how wet citrus roots are, that causes problems, it is the lack of oxygen that causes the problems in wet soils. A wet medium with plenty oxygen will never cause a problem. I know people that grow citrus hydroponically, roots can't get wetter than that. - Silica

My citrus are in a mix of peat, coco coir, large perlite and hampster bedding or would the gritty mix be better? Cathy

Cathy, the gritty mix would be better...That bedding will rob your mix of nitrogen like no tomorrow as it decomposes..Coco coir is ok, but it will compact like peat, will will also compact. The large perlite is ok...Like Silica said. if the roots don't get the oxygen they need they will rot and that kind of mix will quickly do just that...

Thank you so much

I had some turface and today I bought some chicken grit, I had to order some pine bark fines so when it comes later this week I will transplant my trees. I also have foliage pro. Thank you again. Cathy

Yes I agree with Silica that it is the open airy medium that provides oxygen to the roots no matter how much water is applied that keeps the plants healthy. It is a soggy media with no air spaces that is the killer not the actual water. Thanks for making that clearer.

About the gritty mix, can someone tell me approximately how often my trees will need water and if a moisture meter will work for this type of mixture? Thank you Cathy

A moisture meter will not work. I check by digging down an inch or two with my fingers.

Thank you, do you know if it's approximately around a week when you water?

I can't tell without knowing some specifics. Watering frequency depends on a number of things like size of pot, ambient temperature and humidity, size of plant, hours of sun, etc. In the winter, once a week may be OK. With gritty, it is hard to over water.

Thank you very much, I am glad to here that it is hard to over water.

The leaves on my Meyer lemon tree are getting wavy or rippled. I saw on a you tube video that this is a sign of potassium deficiency. If this is correct how do I fix this and how long will it take or how many treatments will it take? Thank you, Cathy

Cathy, please post a picture of the wavy leaves.
