Quick Overview

8 oz BTL HO YOKU MICROTOTAL
Micronutrient supplement for bonsai

Bonsai soil is virtually inert, containing little or no nutrient value. Similarly, most fertilizers contain adequate

amounts of the three major nutrients (NPK: nitrogen phosphorus and potassium) but they usually lack the essential

micronutrients. Although only needed in minute quantities, micronutrients are indispensable to a tree's well-being.

Many of the worrying problems we see in our trees from time to time can be attributed to a deficiency of one or more

micronutrient.

MicroTotal contains eight essential chelated micronutrients: Magnesium (Mg), Sulphur (S), Boron (B), Copper (Cu), Iron

(Fe), Manganese (Mn), Molebdenum (Mo) and Zinc (Zn), in a formula that is extremely effective when applied as a foliar

spray, or can be used as a soil drench during normal watering.

Safe, non-toxic and economical to use.

8oz bottle (enough for a full eight gallons of foliar spray)

Micronutrients
-
Symptoms of Micronutrient deficiencies
-
It is not easy to diagnose specific micronutrient deficiencies without a laboratory and controlled growing conditions

because many of the symptoms appear almost identical and are easily confused with some fungal and viral diseases.

Close observation and consideration of other factors such as climatic conditions, water and soil quality and recent

chemichal treatments should help.
-
However, since we know that our growing media are almost devoid of any useful nutrients, macro- or micro-, it is not

unreasonable to assume that a deficiency of one or more micronutrient is either responsible or a contributory factor in

any of the symptoms listed below.
-
When applying micronutrients as a foliar spray or as a soil drench, always follow the instructions carefully as it is

possible (though rare) to build a toxic level of some micronutrients.

__________________________________________________________
-

Calcium (Ca) - From slight chlorosis (yellowing) to brown or black scorching of new leaf tips and die-back of growing

points. The scorched and die-back portion of tissue is very slow to dry so that it does not crumble easily. Boron

deficiency also causes scorching of new leaf tips and die-back of growing points, but calcium deficiency does not

promote the growth of lateral shoots and short internodes as does boron deficiency.
--
Magnesium (Mg) - Interveinal chlorotic mottling or marbling of the older leaves which proceeds toward the younger

leaves as the deficiency becomes more severe. The chlorotic interveinal yellow patches usually occur toward the center

of the leaf with the margins being the last to turn yellow. In some crops, the interveinal yellow patches are followed

by necrotic (dead and/or dying) spots or patches and marginal scorching of the leaves.
--
Sulfur (S) - Resembles nitrogen deficiency in that older leaves become yellowish green and the stems become thin, hard,

and woody. Some plants show colorful orange and red tints rather than yellowing. The stems, although hard and woody,

increase in length but not in diameter.
--
Iron (Fe) - Starts with interveinal chlorotic mottling of immature leaves and in severe cases the new leaves become

completely lacking in chlorophyll but with little or no necrotic spots. The chlorotic mottling on immature leaves may

start first near the bases of the leaflets so that in effect the middle of the leaf appears to have a yellow streak.
--
Manganese (Mn) - Starts with interveinal chlorotic mottling of immature leaves and, in many plants, it is

indistinguishable from that of iron. On fruiting plants, the blossom buds often do not fully develop and turn yellow or

abort. As the deficiency becomes more severe, the new growth becomes completely yellow but, in contrast to iron

necrotic spots, usually appear in the interveinal tissue.
--
Zinc (Zn) - In some plants, the interveinal chlorotic mottling first appears on the older leaves and in others, it

appears on the immature leaves. It eventually affects the growing points of all plants. The interveinal chlorotic

mottling may be the same as that for iron and manganese except for the development of exceptionally small leaves. When

zinc deficiency onset is sudden such as the zinc left out of the nutrient solution, the chlorosis can appear identical

to that of iron and manganese without the little leaf.
--
Boron (B) - From slight chlorosis to brown or black scorching of new leaf tips and die-back of the growing points

similar to calcium deficiency. Also the brown and black die-back tissue is very slow to dry so that it can not be

crumbled easily. Both the pith and epidermis of stems may be affected as exhibited by hollow stems to roughened and

cracked stems.
--
Copper (Cu) - Leaves at top of the plant wilt easily followed by chlorotic and necrotic areas in the leaves. Leaves on

top half of plant may show unusual puckering with veinal chlorosis. Absence of a knot on the leaf where the petiole

joins the main stem of the plant beginning about 10 or more leaves below the growing point. Continued copper deficiency

can lead to reduction in production of lignin (woody tissue) causing stems and branches to collapse under their own

weight.
--
Molybdenum (Mo) - Older leaves show interveinal chlorotic blotches, frequently streaked, and become cupped and

thickened. some central necrosis can occur. Chlorosis continues upward to younger leaves as deficiency progresses.
