(Click on photo at left to enlarge) Old rootstock of a plum type, which was originally grafted with a peach or nectarine.    So, I cut the rootstock back, and grafted on Santa Rosa Plum on the three limbs on the left, and, two varieties of reliably productive excellent quality flavorful apricots on the right, one of which is apparently the Blenheim/Royal which was originally from a productive old tree in Pt. Loma, and which I grafted out onto two other unproductive aprictot trees, and on which that variety grew out on and continued with it's reliably substantial productivity and high quality, and, the other variety is Newcastle, which ripens a bit earlier than the Blenheim/Royal, but they also overlap in ripening time.  They mostly ripen in June, sometimes into July, and rarely beginning in May.    I can graft these onto your non-productive tree, and you should get plenty of fruit.   In the San Diego area, apricots and plums tend to be most productive in positions which are mostly shaded during afternoon time in winter, which makes for more winter-chilling-dormancy, which is a good thing to maximize apricot productivity with flowering and fruiting.   This would be a position which gives adequate sun/light during spring to summer, for adequate fruit ripening and bud development.   The grafting here was done in mid-June, photo was taken a month and a half later, in late July.   2018.

Photo at left, which you can click on to enlarge is what's described above.   The two photos below show the day of grafting, before and after the cutting back and grafting operation procedures:

A few different citrus grafted on a small orange tree about.  First photo shows growth 4 weeks after grafting, second photo shows growth a few months later, with Bearss Lime on right side two stumps, Meyer Lemon on left side two stumps, and Oro Blanco grapefruit on the middle two stumps in back. Leafy growth on right side is the original orange tree. Grafted in August 2008. White latex paint to prevent sun damage to cambium. Pt. Loma.  Photo below about two and a half years later, same plant, Spring 2011.   Btw, replaced Oro Blanco with Cocktail Grapefruit (cut off Oro Blanco, grafted on Cocktail) in 2012 or 2013, and it's a milder, more 'beautifully flavored' fruit, less acid,... my client said it was the best fruit she'd ever had in Winter/Spring 2015 when the first Cocktail's ripened.

Two different grapefruits and one orange, all on the same tree. Marsh grapefruit is the original tree onto which I grafted a Navel Orange, which is the foreground canopy, and Oro Blanco Grapefruit - left side canopy. The remaining original Marsh Grapefruit is the right side canopy, plus being the rootstock limbs of course. Oro Blanco grafted in 1996, Orange grafted in 2000. Marsh planted about 1970. Pt. Loma, 2008.

Two fig varieties grafted onto a Calimyrna fig. Variety on left limb is the Royale fig, aka Black Madeira fig, a few months after grafting. Variety on right limb is the King fig(aka Honey Delight - W.A. Nursery), one year after grafting. The Calimyrna fig was not producing worthwhile figs because its figs require pollination from Capri figs, along with particular fig pollinating insects called Blastophaga wasps, which are a unique requirement with some fig varieties. Figs sold in nurseries are nearly always varieties that are self-fruitful, and don't require the additional pollination. Pt. Loma.

The stock-trunk-plant was planted some years ago, it was a 'Manila' seedling mango, but the fruit quality wasn't good,... so the owner asked me if I could graft on a good/great quality mango that does well here in the San Diego area.   And so I grafted on three scions of a high quality fruiting Kensington Pride seedling from Leo Manuel(who lives in Rancho Penasquitos) in September of 2012.  Two of the three scions took.  Photo at left(which if you click on will enlarge) is in May 2013, - eight months after grafting; photo above is about exactly one year after grafting, 4 months after the younger photo.   Mangos grow fastest during summer,... but being the graft occurred in early fall, and then winter happened, it grew fairly slow for the first 8 months.  And below, showing it in early 2014.

That's me doing bridge grafting on a California Sycamore for San Diego Landscaping, Inc., at University Town Center near La Jolla, due to trunk injury causing the bark to slough off, which stops the downward flow of photosynthesis nutrition from the leaves to the roots.   August 2017.   The injury was caused by the big-crane hoist technique which was used to install the 50' tall trees.   The trees were grown in containers about 8' wide or so, from which they were taken out of.   As of early summer 2018 the trees are still alive, and with protective buff colored wrapping around the portion of the trunk(s) with the graft operation.
