Cate Macadamia

Macadamia in East Bay? Well, maybe! Macadamia nuts that we all adore are from Macadamia intregrifolia  and Macadamia tetraphylla – tropical tree originated from Australia. The plant I am trying is  a hybrid between the two species, called Cate Macadamia (Macadamia Cate). It is supposedly self-fertile (does not require another macadamia tree to pollinate and produce fruit). I have planted the tree at the end of March, when it was just after flush of new leaves. Second flush started around the beggining of July.

So far, there are no problems with pests, except some caterpillars on the new leaves.

Cattleya hybrids from Hawai

San Francisco orchid show is the biggest orchid event of the year. I have visited it for the first time this year and it really surpassed all my expectations.

I have bought number of plants and among other also three little bags of invitro seedlings of new cattleya hybrids:

t-4993-2-5_20pot t-4888flask t-4959
 T-4993 Blc. Toshie Aoki ‘Encore  T-4888 Blc. Rustic Spots  ‘H & R’ T-4959 Lc. Mini Song ‘Petite’ AM/AOS

There were five little plants in each bag. To my surprise, they survive perfectly the transplant and do very well even 5 months after. I will have soon several plants for exchange 🙂

Loquat alias nispero

Subtropical decorative tree (Eriobotrya japonica) can be found in many gardens around the East Bay, but from what I have observed – most trees are possibly seedlings as their fruits are rather small. Many people do not harvest them – I know of several large trees that are only harvested by squirrels.  Loquat tree can grow up to 14 to 16 ft tall if not trained. In East Bay area it can be planted in a spot with full sun whole day. The wind can damage leaves which are otherwise very decorative. Loquat, especially young trees, may be damaged by temperatures bellow 32F. To produce big juicy fruit and abundant growth in the area, the irrigation in summer is necessary.

Loquat is one of the first fruits to be harvested in the spring, some varieties actually even in the autumn. Tastes maybe between apricot and apple, but of course depends on the specific variety.

For some strange reason, loquat is not commonly found in the nurseries around the Bay area. Somebody told me that maybe they are not so easy to graft, but I am not sure whether that is the right reason.

I finally got a tip that God’s Little Acre nursery in San Jose might have several varieties I decided to make a trip there. Tip was right – they had three varieties:

  • Champaign (white-fleshed)
  • Gold Nugget (orange-fleshed)
  • Big Jim (orange-fleshed)

[More information about loquat and varieties is available here: https://www.crfg.org/pubs/ff/loquat.html]

I have opted for Gold Nugget variety.

Only a few weeks later I have discovered that Berkeley horticultural nursery also offers several varieties of loquat.

Spring diseases on roses

I have inherited several bushes of roses from the previous house owners. Their flower are gorgeous, but they also developed symptoms of some diseases. On the picture below is Black spot (Diplocarpon rosae) and rose rust (Phragmidium mucronatum).

According to my colleague Steve Dreistadt from the UC IPM:

Cultural practices can help for both, more air circulation and sunlight exposure (e.g., prune off some of the rose branches and overstory and nearby plants), no deliberate wetting of leaves… As in Pests of Landscape Trees and Shrubs book.

Black spot is rare in Davis and rust a problem only during very rainy springs and where people overhead water the plants, or grow them too closely/crowded or heavily shaded. This makes clear problem cause is primarily environment and culture.

In Bay Area I’d grow only rose varieties labeled to be resistant. Extent of problem varies by the yearly and seasonal weather. In combination with culture, repeated spraying is sometimes used. Where it’s often foggy/rainy, fungicide effectiveness can be often unsatisfactory.

Conclusion: I will not spray, just remove the affected leaves. My roses are not crowded and have plenty of sun shine. Let’s see if next spring will be different.

Persimmon tree (Diospyros kaki)

I have to admit I was never big fan of persimmon. It was because I have only tried Hachiya type varieties which are highly astringent till soft-ripe. At that time, they are of almost liquid consistence which is not attractive to me.

But then I tried Fuyu type – squat shape and flat bottom. It is mildly sweet, crunchy and can be eaten almost like an apple (I like it with lemon juice).

Tree that I bought if Fuyu type – variety ‘Jiro’. It came from Dave Wilson Nursery and I bought it Home Depot.

Here is description from the label: ‘Jiro’ (“Apple Persimmon”). Medium size, flat shape, still crunchy when ripe, non-astringent. Cool or hot climate. Hardy, attractive tree, practically pest free. Fall harvest. Needs 200 chilling hours. Self-fruitful. Drought-tolerant.

My tree was small, I guess it is 2 years old at max. Its started sprouting ion mid-march and has some flower buds, so let’s see how the flowers will look like and if I manage to get at least one fruit to taste it.

 

Fig tree (Ficus carica)

The variety I have opted for is ‘Panache Tiger’ from Four Winds nursery. I got the tree in Home Depot. Here is description:

 Especially fine Flavor! Small to medium sized with green color and yellow “Tiger” stripes. Strawberry tasty flesh is blood-red in color. Needs 100 chilling hours. Self-fruitful.

Fig trees can be kept below 10′ with regular pruning. Pruning is best done in late fall or winter. It is a Mediterranean crop suitable for dry hot summers and rainy cool winters. Fig is one of drought tolerant trees.

My tree had several small figs which indeed fell down after transplanting. But the tree started to grow really nice just few days after planting.
