TRY ADDING A COMPOST (BLOOD MEAL) TEA WITH A BITTER APPLE SPRAY, NATURAL CAT REPELLENT,  FROM PET SMART, TO ALL STRAWBERRY PLANTS. MIX USED COFFEE GROUNDS INTO THE SOIL WITH ORGANIC BLOOD MEAL, AND A 5-5-5 FERTILIZER. THE ORGANIC BONE MEAL HAS TO BE RAKED INTO THE SOIL EVERY FEW MONTHS, FOR LILAC BUSHES, TO INCREASE THE PHOSPHORUS RATIO, IF IT'S CHOKED BY NITROGEN-RICH GRASSES, WITHIN A YARDSTICK RADIUS AROUND IT. FOUR GALLONS OF IT IS SOMETIMES REQUIRED PER YEAR, FOR FIVE FEET TALL LILACS, IN VERY POOR SOILS. A THICK RUBBER MAT AROUND THE PLANT, A YARDSTICK RADIUS, PREVENTS THE ELEVATED NITROGEN LEVELS (GRASS-INDUCED) FROM CAUSING THE LILACS TO NOT BLOOM. IT NEEDS FULL SUN, WELL-DRAINING SOIL, AND TO BE PRUNED BACK TWICE PER YEAR.
