Hi there, slow & steady wins the race plus you live to stand & garden another day if you don稚 do it all & damage yourself. Compost as I知 sure you致e already found out from any research you致e done is the single best thing you can add to your soil, once it is well rotted be it manure or straight compost it adds so much as a mulch, keeps in moisture,saving you watering too much, keeps weeds down & feeds the soil. Enjoy
