Thanks Charlie for the additional information. It's like being a detective piecing together things one at a time to make sense of the bigger picture. With my heavy wet clay soil I think I was looking for my root systems to actually be negative hydrotropic without realizing that is the scientific classification for that reaction by the roots. So much still to learn...
AG putting out some real nice ones this week.

Yesterday's Prosperity blooms are even more colorful today plus it helps it is more overcast today too.

Chris, nice links but I'm not sure which posts you are referring to that describe or object to your fertilization technique. Also, since these links aren't about fertilizing I'm a bit confused.
However, the links themselves are fascinating and quite informative, particularly the second one which is worth a read by anyone interested in the science behind plant growth.
There are good examples of the tropisms (growth in response to influences such as light, water, gravity, etc) described in the articles readily available to people who have grown hibiscus in different ways and under different circumstances.
For instance, when any of us are growing hibiscus in pots it is very common to see, as David described with his pot of Peppermint Drop, that the roots quickly grow toward the bottom of the pot and then fill out at the bottom of the pot. This is because pots dry from the top down and the wettest soil is found at the bottom of the pot. This is even more so if there is a saucer used under the pot and excess water is allowed to stand in the saucer. This is an example of positive hydrotropism - the tendency of hibiscus roots to grow toward areas of more water availability. It is probably most pronounced in areas where there is a lot of water stress on the plants - meaning hot conditions.
Eventually, in pots that are watered adequately, the root system will fill in throughout the entire pot. David observed the Peppermint Drop in the broken pot before this could happen. The reason we do not recommend using a pot that is too large is that, as you saw, there is a lot of soil that is not being drained by the roots and that wet soil can become a location where pathogens can grow.
Another good example I have seen of tropism and hibiscus roots is when using time release fertilizer that is placed on the surface of the potting mix. You will find a mat of fine roots spread across of the surface of the soil as the roots grow toward this source of nutrients. Root development lower in the root ball can be inhibited in this situation. That is one reason we recommend use of both time release and water soluble fertilizers and making multiple planting holes for the time release rather than spreading it across the surface.
In the commercial setting, one of the most important things we teach workers is to make sure our pots receive sufficient water to wet the entire root ball. If that does not happen the drier soil at the bottom of the pot will become a negative tropism for the roots and they will grow away from this dry soil and the root ball will be restricted with the negative effect on growth that this causes.
Interesting discussion - thanks to all for the stimulating thoughts and observations.

Hi Charlie, I was referring to a previous discussion about Darren's high fertilization regime. Since Darren has referred to my opinion as causing an "uproar" on multiple occasions, I am just trying to provide raw information and no longer state an opinion or provide additional insight. Just trying to keep the peace here. I am glad that you found the links informative, I agree that the second link is particularly good. Tropisms are fascinating especially when one factors the effect hormones have on these effects. Auxin, in addition to regulating apical shoot growth, is also involved in phototaxis. Pretty cool stuff to say the least! |

Dragons Heart and its first bloom from a cutting, triple Sherlock Mystery and Melon Melange. Just 4 today with Cosmic Gold but still looks very nice.

Thanks for both the Links they where very informative Chris. I am not sure why your information is causing an " uproar" most of what you post are facts not "theories"  I don't know as much scientifically about plants so all your information I soak up like a sponge. I am more in tuned with animal biology lol ask me anything about dogs specifically I am your woman haha David nice pictures once again. I do not think I will ever get sick of see pictures from your garden, each one is a real treat ! This is why I love hibiscus in containers. You can achieve the same results as when they are in the ground on a smaller scale. When I started my first garden all of the plants where lush and full like your bushes. |

Thanks kerry, I just love it, I am 56 now and have had many hobbies in my life, football boxing golf but this gardening beats the lot. Well everyone is thanking Chris for them theories, I started to read it and about half way through I just started giggling and then laughing a lot, I thought why are you reading this you daft sod, I haven't the faintest clue what any of it means, it might as well have been quantum physics written in Latin for what sense it made to me haha. |

Nice High Voltage today and in the background 3 Hot Peppers starting to bloom, I shall be pruning HV later today, I need to try and get the size right because as you can see in the second photo I am growing a cutting of High Voltage, and each side of that cutting are cuttings of a white Andenium, when it all comes together it should look very nice.

Bridal Path with strong colours today, and the new bit down the bottom is growing fast, I cant seem to get a good photo here but there is Valentines Day Cranberry Muffin Cream De Cacao, behind C De C I am sure P's Purple is growing an inch a day and a pair of Dragons Breaths at the bottom, when the Adeniums come into flower on either side I am hoping it will look pretty special.

Happy MLK Day to you all!
David the awesomeness just keeps coming with all your blooms!!! All are so lovely.
Norm that is a fantastic Over the Rainbow. The colors are so rich and deep!!!
Deb your Fox Fire is a really pretty and interesting bloom. The way the petals increasingly ruffle the closer you get to the edges is quite dramatic. That is a unique look to a hibiscus bloom!
Kerry - Jasmine has got it made in that shot! Any chance we can train some of those super sniffing dogs we see at the airports into Spider Mite sniffers?
Today's blooms...

Farmerd - love your pics. the AG looks huge - how tall is that plant?
I love Ay Caramba - i was hoping to get it when they had the store opening but it wasn't listed:-(
It may be my favorite color:-)

Last few days the temperature is rising, 90f yesterday and its knocked an inch of Rainbow Sherbert, you cant really notice so much in the photo but as it gets a bit smaller the colours get stronger which is a bonus.
Second photo is of my Bridal Path bush, its now 6 feet tall and looks wonderful, I shall be giving it a big prune in March so it should look majestic in a few months.
Last couple of photo's are of my Plumeria, they are like bouquets of flowers in the sky.
