Iron Necessary To Aid Growth 7 Y F14 Palm Beach Post-Times, Sunday, Nov. 10, 1968 Snapdragon Annual Here 7.0, and one for soils with a pH above 7. Foliar applications of Iron chelates are effective. By PALM HEMKER Iron chlorosis Is one of the more common and serious nutritional problems affecting lawns, flowers, shrubs, and trees in Florida. It may reduce the value of many ornamental plants when ft affects their appearance. Chlorosis usually affects the terminal growth area first and causes a severe reduction In the new growth, and in extreme cases results In death. The first visual symptoms of Iron chlorosis are as a yellowing or blanching of the area between the veins of leaves. The veins usually remain green except that In cases of extreme chlorosis the entire leaf turns yellow or even white. Yellowing of the leaves Is caused by a lack of chlorophyll, the substance that gives the green color to leaves. Iron is necessary in the leaves for the formation of chlorophyll. The soil may often contain enough Iron, but due to conditions within the soil or plant, the Iron may be tied up In a form either unavailable to the plant roots or unavailable for use in the leaves. Iron chlorosis Is controlled by furnishing soluble iron to plants, either through the soil or through the foliage of the plants. Principal types of Iron-containing compounds used to furnish Iron to plants are Iron chelates. You can buy chelates at stores that sell garden supplies and fertilizer. The pH ot the soli Is Important In determing how the Iron applications will be made. Two types of chelates are available: one for application on soils with pH values below Vaughn, has white flowers more than a foot across. The flowers, which appear only at night, are followed by a large, edible purple fruit. TROPICAL ODDITY This Peruvian night-blooming cereus is an example of some of the exotic tropical flora enriching South Florida homes. This cactus, at the home of Lewis Fruit Sets Below 70 Degrees Tomatoes Need It to grow. If growing them in regions such as the Glades, the pH must be raised by adding lime or any other method of making the soil less acid. Snapdragons will tolerate more acidity on light, sandy soils if the soil Is well drained. Prepare soil for planting by applying both commercial and dairy fertilizers. That means use both organic and Inorganic forms. These should be thoroughly Incorporated Into the soil to a depth of six to nine inches. If soil Is to be fumigated for root-knot and weed control, this should be done while the soil is quite moist and fluffy before planting has begun. The next remark must be observed. That is that plants should be set shallow, not much deeper than the way they were grown In the transplant stage. Stem rot a fungus trouble, develops much faster In plants that have been set too deeply. If plants have been raised by a nurseryman In veneer plant bands, these should be removed since they prevent the rapid Spread of feeder roots which are necessary for succulent growth. The root system of snapdragons Is quite extensive. However, the majority of the feeder roots are in the top six Inches of the soil, so deep cultivation should be avoided. When applying fertilizer at any time It should be scratched' In lightly. The taller varieties should be planted twenty-four Inches apart to avoid crowding as they grow and spread. This Is to provide good air circulation, During periods of high temperature and heavy rainfall, a high organic fertilizer should be used to reduce plant starvation through leaching. Dry fertilizer, applied even.' three to four weeks, should be sufficient. If liquid fertilizers are being used, they must be applied more frequently than this. Do not apply nitrogen after buds appear. If feeding is necessary from there on, use a low nitrogen fertilizer. Beware of overfeeding since this can result in soft, weak stems with flower spikes of poor quality. Water carefully so that the foliage Is free from moisture, since snapdragons are subject to rust. However, most good varieties are supposed to be rust resistant. It might be advisable, though, to use a fungicide at two-week intervals to control this. For thrlp and worms, use Chlordane. When flower spikes begin to elongate, supply the stems with' stakes. Adjust these stakes as the stems grow. Snapdragons should be cut low. The second crop will be sturdier If this procedure Is followed. tive growth rather than setting fruit. This especially becomes the case for tomato plants growing over septic drains, In rich organic soils, or In heavily manured beds. Tomato production Is usually best when only enough nitrogen Is available during the first couple of months after planting to permit development of a large sturdy-vine, but not enough to cause a soft type of growth.

They reach their peak of perfection during Feb-ruar. . March and April when liuht intensity is increasing and temperature is still on the cool side. There are strains developed now that can be used for bor-deiini: purposes. Also those that are of medium height, and those that grow very tall. Your choice depends upon where ou Intend planting then: in our beds. There are early and late varieties, some requiring cooler weather some hot. But this makes their use possible over man months of flowering. The (iinger and Rocket strains are some of the most recent first -generation hybrids: also, Carrousel. Hit Parade and Supreme. Weed 'Em And Reap The Rockets are heat resistant, hence can be planted late when hot days arrive. They have been especially bred for out-door use. If. after blooming, they are cut down to eight inches, thev will flower again later. The dingers produce flowers several weeks earlier than the Rockets. They grow better at the cooler time of year, so should be planted earlier. Hit Parade and Carrousel bloom ever. earlier than theGingers. Most ui these hybrids grow to two or three feet, and come in the usual deep rose, yellow, red. bronze, pink, lavendar and white colors. Hit Parade Is the only hybrid that has a pure white flower that remains so when cut. Tom Thumb Is a dwarf, five to eight inches tall. It comes In all the colors of the taller varieties. Miniature Carpet Is a creeping variety. Snapdragons i botanlcally known as antirrhinum majus' will grow in a wide range of soils, trom light sand to heavy loam, excluding acid peat and muck.

If the nitrogen supply is not adequate at this stage of development, the plants will turn ellow and defoliate, leaving the fruit exposed and vulnerable to sun scald. The regulation of the nitrogen supply is an Individual field and seasonal problem, and must be adjusted as the season progresses.

QUESTION: Why does my bird of paradise plant bloom now Instead of in March like it used to? Also, why are some of the flower stems much shorter than others? Mrs. Harvey, West Palm Beach. ANSWER: That is a good question. My bird of paradise blooms around August. I have seen some plants bloom during the dry spring months and some In the late fall as well. Apparently nutrient levels, weather and vigor of plants have a lot to do with when the plants bloom. Like many other tropical plants they don't always bloom at the same season. Often flower size or stem leneth will vary with growing conditions. lUt-OrctH IUli Iff liwi.'i, Trtts, Skrvfes, fkwtfi iMvmtmt I Hit, trtdt twriMf, Itltt lMff w "wnh rt" h iMtvy rtim. itt IkhGrtM ttttff Sif m4t w by BlU GREEN ROTARY SPREADER KNOX FEED & SUPPLY 1001 OWhobt Read Phone 832-3651 FREE PAKKINb UI, wn 3 FOR 5 1.00 St. Riviera Beach M2-3344 supply today I iv a. jv x x INSICTICIDI I A By NORMAN BEZOXA Assistant County Agent Have you planted tomatoes and gotten growth but no fruit? Don't feel like the Lone Ranger. Failure of fruit set on tomatoes is one of the most, If not the most, widespread problem encountered by Florida home vegetable gardeners. In most cases, gardeners report large, healthy, vigorously growing plants with an abundance of large, yellow flowers which mysteriously either drop off or wither Instead of producing fruit. Fruit set in tomatoes Is very-sensitive to certain temperatures. None of the varieties most desirable for planting in Florida will set fruit when nighttime air temperatures are above TO degrees F. There is practically no fruit set when night temperature Is 90 degrees F. in the soil. Also, during extended periods where the temperature during the night drops below 55-59 degrees F., tomato varieties recommended for Florida will not set abundant fruit. The set of tomato fruit is determined long before the bloom appears. The first two clusters are affected when the first and second leaves are only an inch and a half long. Other clusters follow the same pattern. Tomato plants tend to Initiate flower buds under normal conditions as soon as they have reached a certain size or age. This is the time of a changeover from a vegetative form of growth to a reproductive one. Generally, nitrogen applied in excessive amounts prior to flowering will cause the plant to continue vigorous vegeta- Vacation Homes Rise Funny things happen to people when they build vacation homes. Sometimes and this happens more often than you might think they decide to live in them all year 'round. National building statistic-reveal that the number of second homes in the U.S. now has passed the 1 million murk, ami that represents a 60 per cent Increase in the past 10 years. By 1970 vacation homes should represent about 10 per cent of the total home market, and many such homes will get year-round use. Several factors are combining to stimulate the second home bonanza. Americans today have more real Income, more leisure time, and thanks to better highways more mobility. The summer vacation home often doubles as the weekend cottage for all seasons.

Under this condition, the reduction Is probably due to the performance of poor plants. Thus, the plants would likely not be vigorous, dark green in appearance. Under low soil moisture conditions, when water-stress in the tomato plant Is most likely to occur, flowers often fail to produce a mature fruit. This condition may result from some hindrance to the fertilization of the flower, or to a disruption of growth of the little fruit following fertilization. Your fertilizer schedule will begin by applying a one pound coffee can of 6-6-6 or 8-8-8 to 100 feet of row about two weeks before planting. Transplants should be set with a starter solution of fertilizer that is dissolved In water. A good starter solution can be prepared from a soluble material containing 7-10 per cent nitrogen, 45-55 per cent phosphorus and 15-20 per cent potash at the rate of one tablespoon per gallon of water. Use one-half pint of this solution for each plant. Then, side dress tomatoes every two weeks during the growing season with a one-half pound coffee can of 6-6-6 or 8-8-8 per 100 feet of row. Place In a band along either side of the row about four inches from the roots. The fertilizer needs to be diluted with the soil before coming In contact with the plants. Fertilizer is a salt and will burn young tender roots by-direct contact. Tomatoes require an adequate supply of moisture to grow and produce a crop. Water tomato plants about once a week with enough water to soak the soil. It may be necessary to water more frequently when winds are high and the relative humidity is low. Caution should be used in wetting the foliage. The moisture will wash off spray materials and also create an optimum condition for disease de-veloompnt.

Also, what is this enclosed plant's name and how do I get It to bloom? CA, Clewiston. ANSWER: Since I have no Idea what your cultural practices are related to this plant, I can only generalize. Avoid pruning the flame vine. Let it grow. Fertilize with a low nitrogen fertilizer such as 2-8-10 two or three times per year. Do not overwater. I am unable to identify the leaf you enclosed with your card. QUESTION: I have two gardenia plants that are growing tall and bushy. Should I cut them back? TJT, Palm Beach. ANSWER: Gardenias should be pruned in the spring after blooming. This should be done to form a more compact plant, especially If It has become too large. For healthy plants, also fertilize 3 to 4 times per year with an acid type fertilizer plus minor elements. Iron Is one minor element needed In larger amounts than many other plants. It may be necessary to supply extra amounts. For more details on gardenias, write to the County Agricultural Agent's Office, 531 N. Military Trail, West Palm Beach, 33406, for the circular on gardenias in Florida. QUESTION: My crepe myrtle bushes are black with some kind of smut. Is there a spray-that can be used to correct this condition and should they be cut back? Mrs. D. E. Royal, West Palm Beach. ANSWER: The black smutty substance may be sooty mold. This mold grows on plants Infested with sucking Insects such as scale, aphlds, mealybugs, etc. These Insects secrete a substance called honeydew on which the mold feeds. Sooty mold may be found on many types of plants such as citrus, avocado, mango and gardenia. Spray to control the Insects with malathlon or cygon. Also, spray with a fungicide such as dithane M-45 or phaltan.
