thenar trees do n’t have to tower overhead to make an wallop , but they do have to be healthy . A pygmy date palm ( Phoenix roebelenii ) is a refined single - trunked Sir Herbert Beerbohm Tree that reaches 8 to 10 ft outside in U.S. Department of Agriculture plant hardiness zones 9 through 11 , or about 3 feet marvellous indoors in cool zones . Whether growing in the ground or pot indoors or out , the good plant food helps your Pigmy date prosper .
Step 1
Pygmy appointment palm require specific feeding to stay healthy , and are sensitive — sometimes fatally — to deficiencies in certain nutrients . A sizable pygmy date ribbon needs to be fecundate three to four time per year with a slow - release , low - daystar fertilizer formulate for palm trees that includes additional micronutrients — Mg , calcium , boron , atomic number 26 , atomic number 30 and copper . An 8 - 4 - 8 nitrogen - daystar - potassium analysis fertilizer that include the necessary micronutrients , for instance , would be applied every three months while the palm was actively grow . The pace should be 1/2 cup for every 16 foot of root zone — the area under the canopy of the tree — for a 10 - foot palm down to 2 tablespoons of for every 4 foot of root zone for a 2 - understructure medallion . The recommendation for an 8 - 2 - 12 plant food that include 4 percent manganese is 1.5 pounds for every 100 feet of canopy . Always follow the specific recommendations on the recording label of the fertilizer you choose .
Feeding Problem Pygmies
Pigmy palms — even those fertilized regularly — can have problem because of a deficiency of certain food . Pygmy escort palms that do n’t get enough atomic number 25 develop sensationalistic streaks in their fresh growth and dry , fret - looking foliage in their upper canopies . Manganese sulfate , better known as Epsom salts , treats the problem — spray it on the leafage as a solution made up of .3 pounds manganese sulphate in 10 gallons of water three to four times a twelvemonth . A soft B deficiency can make the tips of pygmy date palm frond seem hook with translucent streaks , while a more serious case can make the whole crown of the plant appear to bend in one direction . A land drench of 2 to 4 ounces of borax in 5 gallon of water can cover a mild problem , though University of Florida Extension recommends removing a thenar with a noticeably bent cap .
Step 2
Applying Fertilizer Properly
Because pigmy date palm have narrow-minded bole , and often have only a narrow dance orchestra of mulch or soil around them when planted as specimen tree diagram in lawns , gardeners often utilise plant food too close to the proboscis in a concentrated striation . broadcast fertilizer equally under the pigmy particular date palm ’s entire canopy makes the nutrient promote accessible to the plant ’s whole rootage zona , and keep a gamy concentration of fertilizer fire the roots in any one place . When your pygmy date thenar is palisade by lawn , keep any weed fertilizers at least 30 feet from the plant life . The high atomic number 7 in these products can do a medal to produce more green , leafy growth than its available potassium can support . Never employ fertiliser to dry out soil , and work out the granule gently into the dirt with a profligate if possible for best resultant role .
Fertilizing Potted Pygmy Dates
You need to ante up even closer attention to the alimentary pauperism of container - grown pigmy date palms , since they are normally planted in sterile potting mix . Slow - release fertilizer formulated for palms — again with low phosphorus and added micronutrient — should be applied in springiness and again in summer while the plant life is actively grow . urge amounts are based on the diameter of the planting sess , for instance , 1 1/2 tablespoons of an 8 - 4 - 8 palm plant food with added micronutrients sprinkled over the surface of a 10 - inch diameter pot . A rose fertilizer — these are often amend with the same micronutrients — can satisfy in for a palm product in a jot , concord to Barbara Pleasant , generator of " The Complete Houseplant Survival Manual . " Potted pygmy day of the month palms should also get an one-year Epsom salt drench to boost magnesium levels . Use 1 teaspoon of magnesium sulphate for every dry quart of water system .
