Size:

15'-20' tall 

Growth Rate:

Moderate in our dry desert

growth slows over 100°

Watering:

  • When our temps are hot this tree will want extra water. 

  • Deep water, filling the tree basin two-three times a week in summer months as it encourages deep roots. 

  • Water very little in the dormant "cold" winter months, moderately in spring and fall & heavily in summer. 

  • Mulch heavily to help maintain moisture

PH:

6.5-7.6 acidic to slightly alkaline.

Container Grown:

  • Yes

Fertilizer:

  • Use a 8-8-8 fertilizer in mid winter and then every 90 days for potassium nutrition. Mix 4 ounces of nitrogen per inch of trunk diameter, under the tree drip line which will expedite its growth. Under lower light and cool temperatures, reduce the frequency. When active growth stops in winter, discontinue feeding.

  • When planting add worm castings, compost/manure, trace minerals like "Azomite", and a good mycorrhizae to start of the beneficial fungi and microbiology for your young tree. Make sure the soil drains well as they are not a fan soggy feet. Mulch very heavily. A base of mulch 12"-18" deep is recommend. as is the addition of worms if your soil does not have them.  

  • This tree has a low salt tolerance-flush regularly! 

Pruning:

  • Prune when the plant is dormant unless due to branch breakage.

  • Train the tree to two scaffold branches at 2 feet of trunk, pruning them to a 2 foot length. Save only the strongest single shoots, preferably those at 60 to 90 degree angle, and remove the others. In the following years, remove two-thirds of the previous year's growth, leaving six or seven good buds, at time of new growth. This will keep fruiting wood within reach of the ground. Thin out crossing branches.
