Pineapple guava -- advice re fertilize, hand-pollinate?

otherchuckMay 30, 2012


I have two pineapple guavas I planted maybe ten years ago, and while they appear to be healthy (despite having their leaves occasionally grazed a bit by ground squirrels), neither has ever produced any fruit. One is about 7 feet tall, and the other is about 5 feet tall, and it SEEMS to me that they are growing in ideal conditions (sun, soil, climate, water, etc.). I live in the Santa Ynez Valley, north of Santa Barbara, CA, USA, which is zone 14 according to the Sunset paradigm.

I am not a big fertilizer at all by nature. I grow mostly native-style plants that really don't seem to need or want much fertilizer, so I am nervous about fertilizing the pineapple guavas. However, should I fertilize these two trees in hopes of boosting their growth? If so, how much, and what kind of fertilizer should I use? It is now the end of that an acceptable season to fertilize these trees?

The two trees are about 50 yards away from each other, so I am thinking maybe it wouldn't hurt to hand pollinate these guys (I don't know if these are self-fruiting or not). How does one hand pollinate these kind of trees?

Thanks in advance for any advice!

That is awfully slow Feijoa growth for ten years. Mine would grow over two feet per year if I didn't pinch the new growth when at one foot. All this growth with only a couple of inches of composted manure added every few years.

You imply your plants bloom but do not mention how much.

When you tap on a blooming feijoa branch, pollen does fly off. 50 yards is too far for reliable wind pollination.

You do not even need a brush to hand-pollinate these. Just thoroughly molest the blooms by fingertips, touching all the flower parts (except the petals). 2 or 3 seconds per blossom is enough, just concentrate on the fully-open blooms that have yellow pollen on the stamen tips. Once the stamens start to fall off the flower, it is too late.

If your plants are seedlings, extra effort may be in vain. I've seen quite a few plants up here in Portland refuse to fruit.

I have two Pineapple Guava�s in my front yard. One planted three years ago and another 6 feet away that replaced a dead one last year. The three year old one is about 3 feet tall and just as wide. It has had plenty of fruit before and is loaded with flowers right now. The newer one has grown up to match the older one in size but has no flowers so far. I expect to see fruit growing on the older one pretty soon.

I toss a handful of general fertilizer at each one about three times each year. I have not attempted to pollinate either one. I�m about 30 miles North of LA.

I had a tree for over 10 years and it never gave but one or two fruits despite lots of blooms until I tried this last year (see link below).

Then it was loaded. Looks silly, but it seems to work.
