Using clean credit card is indispensable to heat retentivity . slender plastic sheeting is also recommend , no more than 1 to 2 millimetre duncish , as it allows the sunlight to sink in the plastic more well in society to heat up the soil underneath .
What Time of Year Is Best?
Though soil solarisation can be effective for six to eight weeks in the outpouring prior to planting , or in the fall just after harvest home , the practice is most efficient during the heat of the summer , when the soil receives the maximum amount of photograph to sunshine . Summer solarisation is the most effective for pop weed seeds and soil pathogens that are lurking deep within the soil .
Length of Time and Location
Unfortunately , the shortest amount of time necessary for the solarisation process to make is six to eight week . This amount of sentence is also recommend for areas in the deep south ( or other extremely hot area ) during the hottest months of the year , in a year with a stack of sunny days . In the mid to upper south , gardeners should increase the length of the project to around three months ( June , July , and August ) , and in more northerly part of the state ( or colder clime field ) , solarization will only be in effect if the plastic stay in plays for the entire season in a full - sun positioning during an especiallyhot summertime . It is also recommend in cooler climate areas , that two rag of charge plate are used instead of one . The extra layer of credit card will help to heat the dirt more by trapping warm aura between the two layers .

How To Solarize Garden Beds
Step One – Prepare The bed – Till the garden country that you are desire to solarize , removing any debris , such as rocks , pack land clots , roots , and anything else that does n’t go . Rake the domain until you have a smooth and level Earth’s surface . Next , irrigate the orbit until the soil is about 70 % saturated at least two substructure below the surface . rather , the soil should be moist but not soaked for the solarization process , but there will be some clock time for the urine to ooze deeper into the ground as the next step are dispatch . Moisture will help high temperature permeate the ground leisurely , and moist soil egress are well suited to solarization in a moist environment .
Step Two – Dig A Trench Along The Edges – Before breaking out the plastic sheeting , dig a deep along the outer bound of the garden bed that you are planning to solarise . The deep should be about one foot wide-eyed and eight to 12 inches deep . Take your time digging your deep , as the more even and well made it is , the better it will make and the more even your plastic sheeting will lay out and stretch across the top of the garden bottom , which will keep less air pockets from jump to the top .

Cover the integral garden area that you are solarizing with thin , clear , charge card sheeting . big rolls of plastic sheeting can be found at most home and garden centers . invest the edges of the credit card sheeting into the trench you dug and backfill with previously turn up soil from the trench digging , keeping the credit card pulled as tight as possible during the process . The closer the plastic is to the soil itself will bet on how tightly the charge plate is pulled across the country as well as the precision and smoothness of the leveling that you were able to obtain when prepare the layer . The familiarity of the charge plate to the topsoil is crucial because it keep breeze bubbles and breeze pocket from forming along the top . superfluous air can keep the soil from reaching temperatures that are mellow enough to solarise the soil in effect .
Step Four – Wait Six to Eight Weeks – Unfortunately , there is no acquiring around the long waiting period that solarization requires . If you become impatient and decide to uncover the grime and plant your crops before six to eight weeks time has elapsed , then all of your oeuvre has been for naught . Once six to eight hebdomad have fall , polish off the charge card , water the soil , work out in somecompostor organic affair and decide what you want to grow in your newly ameliorate and solarized garden bed .
footprint Five – Plant Right Away – Planting and growing a raw group of crop in your freshly solarise bed is important for multiple reasons .
