Lri Green leaves DO-IT-YOURS- food for plants, yellow leaves do not. Plants without food soon terminate. So, if you would like to see your plants continue on AND SAVE SPECIAL... Pre-- f make sure the leaves stay green. There are a number of reasons why leaves on plants turn yellow. The principal one is lack of available iron in the soil, caused by a high lime content. Soils that are derived from limestone rock are more likely to produce iron chlorosis (yellow leaves) than are soils that are derived from granite or other rock formation. Some plants are abl. to obtain enough iron in a high lime soil under normal conditions but turn yellow when anything occurs that reduces the root g kills out area. some roots and this practice often causes yellowing. Deep cultivation cuts off part of the roots and this may produce an iron deficiency where available iron is low. Insects that bore into the bark and girdle trees can produce chlorosis. Borers and grubs in the roots of peonies and some other plants cause the foliage to turn yellow. And heavy fertilization which stimulates more than the usual amount of new growth, will also create a demand for iron in excess of the available supply. There are some other ways of producing chlorosis but those mentioned will do the job quite adequately. inished WOOD PANELING The LARGEST STOCK OF PANELS IN UTAH Because of our huge volume purchases of paneling you get lowest prices available SELECT FROM 100 Over-waterin- DIFFERENT PANELING & VARIETIES STYLES 1st 1st QUALITY ASH PANELS BIRCH PANELS 4'x8 95 VARIOUS COLORS FOR FACING DOORS AND CABINETS 4'x8' PANELS PANELING VARIETY OF PATTERNS AND COLORS Its, 1 95 F I FIBERGLASS panel 395 49s I I ODDS & ENDS OF PANELS and 4'x9' 645 1 I KAISER ALUMINUM $S0 OR MOM OOD PULP BLOCKS may join peat pots for use in planting seeds and cuttings. The blocks will be divided into cubes (as in an ice tray). A seed or cutting may be grown in each section, which will have all the plant nutrients needed, plus an element to protect seeds or plants from decay. When you are ready to set the plants outdoors, you break off the cubes and put them in the earth without disturbing the roots. The roots will grow through the cube and into adjacent soil. The cube dissolves and helps fertilize. The idea was developed at the Wisconsin Agricultural Experiment Station. Grooved and Etched for tho Rustic Look 2 FT. TO 514 FT.

CORRUGATED GALVANIZED IRON FOR ROOFING AND r-- f WALLS. FROM 6' to 12' LENGTH U TO CORRECT IRON deficiency the addition of iron to the soil or to the foliage will often help. Years ago iron sulfate as a spray or soil treatment was the best source of iron. It still Is for yellow lawns, but the chelated forms of iron are better for most plants. over-watere- d Chelates are available in most garden shops and complete directions are on the container as to dosage and method of application. These are not miracle compounds but they will usually correct chlorosis when used according to directions and applied with persistence. Start now, late summer and fall applications are less effective. The alert gardener who has a chlorosis problem persistent will select plants that stay green under his soil conditions and avoid those that are more subject to yellowing. Of course, if you must have a white birch tree you may have to treat it to keep it green. Early spring and late evening is the best time for foliage sprays. Soil treatments work best early in the growing season. Iron poor blood in people and chlorosis in plants are similar. If you have the former you may be too tired to correct the latter. eeders AMoctatod 4'x8' To avoid yellow leaves In your plants then, keep the roots intact and healthy and avoid application of nitrogen fertilizer where plants are inclined to turn yellow. uide by Earl Aronson U 4'x8' in Vs" Thickness REMNANTS FIBERGLASS ON 95 'llI 4 SIZES FROM: 6 ft. to 12 ft.

Thats why new pesticides are being developed constantly as old ones become less effective. How does immunity build up in insects? Some insects are born with a natural resistance to certain insecticides. They escape normal spraying that may eliminate most of their relatives. The survivors go unnoticed at first. But as they reproduce, their offspring inherit the immunity and eventually a whole colony of immune bugs builds up. Pmi Writer One such bug Is the lawn chinch, which keeps busy all summer and can ruin a costly lawn quickly. Others are the tiny mite, and in the South, the Bermuda mite, another lawn pest. One insecticide reportedly able to control 120 different insects is Diazinon (Geigy), for use on trees, shrubs, flowers, fruits and vegetables. A MAJOR INSECT pest of apples, the apple maggot, may be lured into traps by certain colors and shapes. Agricultural Experiment Station reports that, early in the season, flies that lay eggs to hatch into maggots that ruin fruit are attracted to yellow rectangles. Later, they fly to dark spheres, apple size or a bit larger. can numbers be Large trapped if the yellow rectangles or dark spheres are coated, as is flypaper. This wont trap enough of the pests, but ultimately, scientists hope to find a way to sterilize maggot flies that alight on a nonsticky paper and then fly away. This would be birth control. Entomologist James B. Krlng. a pioneer in the use of colors and In reflective surfaces repelling aphids, also has Investigated ways to neutralize insecticides in soils.
