Lime tolerance

Eucalypts do not require fertile soils and will thrive on both acid and moderately alkaline soils from pH 4.5 to 7.5. The subalpine species naturally grow on thin poor rocky soil and grow much faster when grown in this country on better soil. On dry shallow chalk or limestone soils with a pH above 7.5 only grow E. cordata, dalrympleana, macarthuri, nitens and parvula

However, feedback from customers who have grown a large range on soils of pH up to 8.5, suggest that after initial chlorosis growth is acceptable from non lime tolerant species. The author cannot confirm this point. They will grow on slow draining clay soil but will not stand up to permanent water logging. Some species will, however, tolerate poor drainage and partial waterlogging.
