Plant Height. Basil usually grows to a height of 12 to 18 inches (30 - 45cm). Basil plants should be spaced between 9 and 12 inches (22 and 30 cm) apart. Basil will grow in a very wide pH range between 5.1 (strongly acidic) and 8.5 (alkaline) with a preferred range of 5.5 (strongly acidic) to 6.5 (mildly acidic).Sow seed indoors before last frost or direct sow outdoors after last frost.referred pH Range. Basil will grow in a very wide pH range between 5.1 (strongly acidic) and 8.5 (alkaline) with a preferred range of 5.5 (strongly acidic) to 6.5 (mildly acidic).
Ocean spring temperatures range from an average of 60 degrees Fahrenheit (16.5 degrees Celsius) in southern California to 50 degrees F (10 C) off the state's northern beaches.
The far southwest (central and southern California coast) has a Mediterranean climate. Daily high temperatures range from 70 to 80 Â°F (21 to 27 Â°C)s in the summer to 50 to 60 Â°F (10 to 16 Â°C)s in winter, with low temperatures from the 60 Â°F (16 Â°C)in summer to 40 Â°F (4 Â°C)s in winter.[citation needed].ake-effect snows add to precipitation potential downwind of the Great Lakes, as well as Great Salt Lake and the Finger Lakes during the cold season. The average snow to liquid ratio across the contiguous United States is 13:1, meaning 13 inches (330 mm) of snow melts down to 1 inch (25 mm) of water.
