Arguably the most inhuman - hardy of trunked sports fan - palm metal money , windmill palm ( Trachycarpus spp . ) mature its roots and new frond during the fond month of the growing time of year . Once temperatures drop below 60 grade Fahrenheit , root ontogenesis greatly slows and nutrient uptake is slowed . Thus , any nutrient deficiencies seen in fall will likely deepen across wintertime . Having a fertile dirt with all necessary nutrients year - round secure a windmill palm tree is healthfully with no lapses in dirt nutrition . Windmill palms readily live on wintertime that drop no cold than -5 degrees Fahrenheit .

Understand your Soil

All palm postulate plenteous amounts of nitrogen , potassium and atomic number 15 , as well as trace amounts of micronutrients to sustain key metabolic processes or tissue paper . vestige elements like magnesium , smoothing iron , calcium , boron and manganese must be present in ground or container soils . deal a nutrient psychoanalysis and pH examination of the soil near the windmill palm . Knowing exactly what nutrients are miss helps you make an effective fertiliser regimen . Acidic soil allow palm roots to engage more corpuscle of trace nutrients .

Types

The Australian Palm and Cycad Society and Jungle Music Palm and Cycad Nursery of San Diego , California , note that rich ground do n’t necessarily warrant the purpose of fertiliser for the health of windmill palms . arenaceous , alimentary - poor soils certainly justify fertilization to prevent leaf yellowing or weak emergence . gardener choose either organic or semisynthetic ( man - made ) fertilizers . Organic fertiliser include compost , mulch , fish emulsion and ivory meal .

Time Frame

constitutive plant food are slow to break down and release nourishing molecules for use by windmill laurel wreath roots . Such fertilizer is apply anytime of year , specially compost and top - medical dressing mulch , but the warming months of spring and summer call for the most care . Granular synthetic fertilizers demean over calendar month based on moisture and temperature ; applications concord to product label guarantee fertilizer is present year - pear-shaped . New , fresh applications are good in spring and summer months to coincide with the innate growth of newfangled roots and fronds .

Composition

A general rule for a good synthetic formulation for palm fertilizers is 3 - 1 - 3 or 3 - 1 - 2 with micronutrient , according to APCS and Jungle Music Nursery . These " well - poise " fertilizer , often marketed as " general all - aim " or " landscape " formula have nitrogren , phosphorus and K levels in the 3 - 1 - 3 or 3 - 1 - 2 ratio . For example , a 12 - 4 - 12 fertilizer with micronutrient is idealistic ; whereas a 30 - 0 - 0 is not , since it is too full-bodied in nitrogen and is lacking other necessary component . fluid fertiliser are perhaps not the best , since the salts in the root can burn palm tooth root and leach through dirt apace when compare to slower - acting organic and ho-hum - release synthetical granules . Approximate ratio are acceptable , as you may obtain a " rose " fertiliser has the nutrient in a proportion that is best for your windmill palm .

Concerns

Never overfertilize the windmill palm , especially with fast - acting liquidity fertiliser , since they can damage ancestor . Be uniform with your fertilizer regime , whatever components you decide to use . Supplementing your natural soil ’s fertility with slow - release fertilizers guarantees the soil contains nutrients for the thenar roots at any clip , but particularly in spring and summertime . Always utilise fertilizer to moist soil , and never focalise primary lotion in previous fall and wintertime menstruation .
