Can anyone help me? I planted 10 dwarf citrus trees on my property about 6 months ago ranging from grapefruits and Myer Lemons to Key Limes and Valencia, just a nice mix. All the trees are on drip irrigation and 4 of the trees are doing pretty well, but the rest are not doing very well. 1 tree has lost all of its leaves completely, 4 of the trees are slowly losing leaves with no new growth and 1 of them has new growth on the bottom, but is losing leaves on top. What is the correct watering for outdoor dwarf citrus? I have had my trees on all sorts of different types of watering cycles and only 4 of them have responded to the last one. Originally a nursery stated that I was to water for 10 minutes on drip once a week and keep the moister measured at 5 or 6. All the trees seemed to stop growing and began to lose leaves. Another nursery stated that they need to be swamped once a week on drip with standing pools of water. The trees stopped losing leaves, but did not grow any further. A final nursery stated that I had to swamp them with water on drip for 45 minutes to an hour everyday with fertilizer once a month. 4 of the trees now have new growth and the other trees are either losing leaves still or just in a state of arrested development. Do the trees need to just get over the shock of not being watered enough and given time? Am I on the correct watering schedule finally or is it too much? The soil varies from decomposed granite to clay to stone with a warm / dry Mediterranean climate where temperatures can get into the 90Ã¯Â¿Â½s or even 100Ã¯Â¿Â½s, but never freezes much. Any advice is much appreciated.
