Well, I think we filled up on our rain quota... now everything will rot.

After going through a good spell of dry weather, we had some rain, then we had LOTS of it.

I don't have television and thus watch news/local stations, but if the internet is sufficient news enough, I assume that many of you heard about the crazy storms/tornadoes in Mississippi and Tennessee.  I'm just glad that I don't live in Nashville, I had no idea that so many houses there were in such close proximity to creeks and rivers that could just overtake them like that.

Best to you who live there and have had to endure those storms and I hope that no one else gets hurt.

Now that I feel like I won't have to water for a few weeks (though the forecast seems to predict a couple of showers over the next 10 days) the amount of rain has me worried about fungus, as it will take forever for all this to dry out.

All my vegetables/fruit plants are in raised beds, and though they drain relatively well, I think, my strawberry plants have been quite happy in them... and now I am kicking myself for not having thinned the plants out more (avaricious for strawberries, I have been).  The leaves, though off the soil/ground are lush and there's probably less air flow going through than I like and because the leaves are such a great canopy over the soil they're in, they are preventing light to reach beneath and dry things out faster.

Good for when it's drier out, when moisture needs to be conserved, not so good when things need to seriously not be soaking.  Well, I'm glad diatomaceous earth is like those gel packets and absorb moisture, maybe I'll just dump it all around and it can soak up a few gallons per bed! (I wish).

After strawberry gathering yesterday I did find fuzzy gray moldy fruit and stems and am now keeping a close eye on the strawberries.  Last year it was slugs, this year let it not be mold that takes my strawberries down! Luckily they're everbearing so I get more than one crop, but still... fungus needs to go so I can keep continuous clean crops.

Unfortunately the organic treatment of molds like these is sulfur-copper sprays, which are not reliable compared to their inorganic brethren, and it would be yet another expense to the garden list. *sigh*


Neem is supposedly a fungicide too, don't know if they affect all fungi though and I hate the idea of spraying more liquid on my already damp plants.

Will  just have to watch and wait (unless it all goes down hill quickly, then I'll just be annoyed).

Hope that your gardens are doing relatively well despite the ridiculous rains and that mold/fungus (unless it's the good kind) stays away from your plants!

Soil Nutrition Part 2 of 3: Calcium, Magnesium, Iron & Sulfur

(I would like to note that I am not a horticulturist but have simply compiled a lot or research and resources and wish to share what I have learned in hope it helps others.  As there is a lot of info and resources in this, I have broken this article into 3 pieces and will list all the resources at the end of this part 3)

Just like many living organisms (especially for us women), plants need calcium as well to produce a STRONG structure.  Bones in our case, and cell walls for them.  Calcium is also important for protein formation and its alkaline pH  neutralizes overly acid soil that might prevent uptake of other important elements plants need.  Straight calcium is hard for plants to utilize as it is not readily dissolved, and better forms of calcium for uptake include lime, gypsum or seaweed/algae.

Sign of Calcium deficiency include:

-blossom end rot
-curling or yellowing of leaves
-brown tipped leaves
-growing points show damage and die off
-stunted plants
-forked root crops

Natural Sources of Calcium:

-Egg shells: better if dried and crushed or powdered ahead (though I rarely do)
-Powdered milk/sour milk/yogurt: Sprinkle powder milk around base of plant or make into liquid form (or use dilute milk or yogurt) and water.  Spraying with either reduces powdery  mildew because of its lactic acid.
-Seaweed



If you have ever noticed your plant going all Prince (Artist Formerly Known As/weird symbol/whatever) on you, aka Purple-y, you’re probably experiencing a magnesium deficiency.  Magnesium is needed for chlorophyll formation and when it gets out of whack in a plant, things get a little psychedelic purple… or just yellow, blah.  This elements needs to be in balance with calcium so if magnesium is going wrong, your calcium might too.

Sign of Magnesium
deficiency include:
-yellowing or yellow spotting of leaves
-purple/reddish leaves
-poor crop flavor

Natural Sources of Magnesium
:
-Epsom salts: (magnesium and sulfur source) There is caution in this, especially about over application of Epsom salts and if you are unaware of the needs of your plants/soil conditions, please research before application
(Cautionary link: http://www.puyallup.wsu.edu/~Linda%20Chalker-Scott/Horticultural%20Myths_files/Myths/Epsom%20salts.pdf)


If we couldn’t get all our plant symptoms all the more mixed up, with yellow leaves being an indicator of EVERYTHING it seems, then plants lacking iron will not surprise you by looking anemic (yellow) too when they are lacking this element.  Iron is vital to chlorophyll production and thus, when there is a shortage this deficiency is called chlorosis.  One trick to note if your plant has chlorosis  is to note if it has green veins.  Iron also helps make plant proteins (think of muscles/meat=protein) as well as enables plants to fix nitrogen for use.  As fixed elements go, if the pH is too high iron becomes locked up and an alkaline like lime can free it.  (I imagine a lime fruit riding in on a horse, wielding a sword to free a laundry device in a tall tower.  I know, I’m weird).

Sign of Iron deficiency include:

-yellowing of leaves with green veins
-quick growing plants will show signs of damage first

Natural Sources of Iron:

-Blood: (either in meal form or I have heard that some farmers in the old days would use slaughtered animals’ blood or in ancient times they would water plants with high iron needs by hanging an animal whose throat they slit above such plants.  Gruesome, but it works I suppose).
-Some hardwood mulches might leach out iron I’ve read, but I can’t find it confirmed.


The last necessary element for this section I want to mention is sulfur.  Proper protein production  requires sulfur (it's used in certain bonds to form protein) and a plant that lacks available sulfur will find it difficult to produce new leaves as plant growth hormone regulators need this element to form.  Sulfur is linked with iron and can help remedy chlorosis, when sulphates are added.

Sign of Sulfur deficiency (usually only a problem in sandy soils) include:
-even yellowing of leaves especially in new leaves
-slow growth of new leaves

Natural Sources of Sulfur:
-Matches: Only a little is needed and some people swear by burying wood or paper matches with plants or if they think there’s a deficiency.
-Epsom Salts
-Blackstrap molasses: sulfur and trace minerals (great after baking gingerbread or molasses cookies!)


-unfortunately can’t find more ‘natural’ sources… if you can think of any that don’t come in a bag, please tell me!
