All Trees in Orchard gardens

Yum Yum mix, once a year usually in fall.

Cottonseed meal (5-2-1) and either Greensand (varying NPK but no nitrogen, lots of trace minerals and iron) or Planters II (aka “Mineral Boost,” also a trace mineral source, with calcium) are applied two times, in fall, along with fresh compost applications.  These applications were about 3 years apart (in 2016 and 2019).

Most deciduous trees also receive 1 to 3 applications of liquid fertilizer blends, approximately mid spring and mid June, and there is time in mid to late July.  The blend includes a seaweed product and a higher nitrogen product called “Grow” (12-6-6, by Age-Old). 
Note: 

The fruit trees used to be included but no longer since they are showing fine foliar and woody growth and more structural growth. It is better that these trees slow their growth and put more energy into flower and fruit production. They are occasionally treated with seaweed early in the season to help compensate for cold spring “feet”.  The apricot tree seems particularly susceptible to chlorosis and a slow start in the spring.
The few crabapples remaining are not fertilized as they all have fireblight and fertilization is counterindicated.  (The pear trees also have fireblight but the varieties are “resistant” so the disease is not expressed much in plant growth or fruit production.)

Fresh mulch as needed—usually about every other year.

Expansion of irrigation as trees have grown: most trees have gotten additional 3 to 6 or 8 emitters, further from trunk than original placements.

Trees in OYM

Yum Yum mix has been used on the deciduous trees as well—it’s been more like every other year since they were planted in 2016.
 
The oaks and the NM Privets have been treated with the seaweed and weak concentration of “Grow” in spring and summer.

Rose-Lavender beds and Orchard Perennial Gardens
Yum Yum mix is scratched in after pruning and spring cleanup. This has become more difficult as the groundcovers have covered more of the earth between the roses or perennials. The roses are always treated with liquid treatments over the summer, about 4 or 5 applications of Age-Old “Grow” and seaweed early in the season, changing to Age-Old “Bloom” (5-10-5) and less seaweed from late June on.  The perennial beds get the same liquid supplements but less frequently—generally one in spring and one or two in summer.

Most other plants in the gardens are not fertilized regularly.  Occasional spot treatment with the liquid treatments named above are used for plants that seem stressed or are under heavy flower production.
