[IBC] soil situation
After spending time with local club members, I have more questions than
answers about what I should use for soil in the desert. Everyone I have talked to uses cactus mix, one person in particular uses cactus mix with composted bark and peat. He says that raw organics that haven't been composted take nitrogen from the tree as they decompose. I have been using the raw fir bark, turface and pumice mix and have found it to dry out way too fast. At this point, I don't see anyone using a coarse mix, but I have seen composted cactus mix work very well. I have bought trees from Mike Hagedorn that are in a soilless mix of lava rock, akadama and pumice. They do great in Oracle (Zone 10) but are traumatized or killed by the desert heat (Zone 12) in that mix. The ones I have repotted in 1/2 organic mix turn right around and are very healthy. Finally, is the composted material better than raw? It seems the desert puts the trees and soil to the most extreme test and it is a bit confusing. Though, the experiments continue...

Brian in Tucson Ah! Soil mixing! I see you are very observant on what does and doesn't work in your area. I encourage you to continue to experiment until you get what you need for your area. It is true that raw organics take nitrogen away to decompose, but you can feed around this. You just have to be careful to feed a diluted solution often. I feed every other week in summer. I alternate foods several times during the season. I use fish emulsion, a sea weed mix, miracle grow, Peters, and 0-10-10 as a go to sleep and wake up food. I use Whitney Farms starter food in my plant mix as well as green sand, cotton seed meal, and a sea weed mix. I use these sparingly. Other considerations are how often do you water? I live in Northern CA in what used to be a semi arid region, but we don't have the temperature fluctuations you would have in the desert. I change my mix and add more organics depending on if it is a drought year or not. I have my watering system set up to go for 5 minutes twice and day and I also hand water selected plants. My current mix is designed to be fast draining, but has moisture retention. This way I can flush what is needed through the soil rapidly. My mix is different than folks that live more than 15 miles from me because some parts of this valley are dryer and hotter than others. I also adjust it to suit specific trees. It has taken me 20 years to have the soil knowledge I have now. I used to change mixes every time a new guy came through town with a demo. I lost plants using soil mixes that were generic instead of designed for my area or watering habits. I use combinations of red lava, pumice, akadama, various composts, peat, fir bark, sand, planting mix (this is a coarse, partially composed material sold for CA clay soils). Some times I find things like "forest compost". I buy a bag, take it home and check it out. If it is not too fine, I go back for more. Supersoil Orchid Mix used to be nice as part of a mix or for shohin, (coarse peat, fine fir bark and sand) but the recent varieties have too much dust in them. I go to a garden supply center and have bulk ingredients dumped in my driveway. Then I shovel it into plastic garbage cans and wheel them into the back yard. I like this because I can handle the ingredients before I buy. Also with bulk ingredients on hand, I only have to shop every 2-3 years.

[IBC] Soil Situation
Watering is a key factor in the desert, not just because it's hot, but
the old rule of water until it runs out the bottom doesn't apply here in the summer. The best trees are kept by people who water through tthe bottom once a day and water the top parts through the rest of the day. I have to work in the mornings so my wife waters the tops in the morning and I water through in late afternoons. It's not ideal but I haven't lost a single tree this summer, which is better than other club members with much more experience. Mike Hagedorn showed me how he even waters certain spots that get more afternoon sun than other spots that get morning sun. He also has monster pines with thick foliage. One other point is about fines. My buddy, the local native expert, says fines, along with composted organics, is the key to success. Not just with deciduous but even with natives! He says it's the key to keeping his Mazanitas as well as he does, and he has a few and some large ones in small pots. I am currently trying different combinations but am uncomfortable using much of the fines. The more I discover here the more I think the normal rules of bonsai are flipped upside down!

[IBC] Soil Situation
Brian,
Your points are well taken. The best and easiest way to figure out how to grow trees in a climate is to find someone who already has this figured out. If their trees (in containers) look good duplicate their soil, pot size, light exposure as best you can. If their trees do not pass the look test then find another "expert". From there experiment on your own trees, and in your own micro-climate will bring you the rest of the way to perfect growing conditions. Sounds so very easy.
