Citrus and Peach trees

[Pops]

In my mailbox:

Dear Michael:

NCAT horticulture specialist Guy Ames is embarking on a comprehensive update of our ATTRA publication Organic & Low-Spray Peach Production (2003), probably also incorporating information on organic and low-spray plum production. As always, we are interested in institutional research but also GROWER EXPERIENCE.

Because farmers (especially organic farmers) are so often conducting their own research, and because organic production of peaches and plums is so difficult, Guy is interested in what worked for growers and--just as important--what didn’t work. He is especially interested in grower experience in the humid eastern half of the U.S., but information from anywhere would be helpful.

If you are willing to talk to Guy and share your experiences and information, write him at guya@ncat.org . Also, if you work with an organic growers’ group, please share this request with them, perhaps even through the group newsletter.

Thank you for your assistance.

Did you send the mailer a link to this thread?

Fortunately, and perhaps I've just been lucky, but so far I have had no major problem with bugs in the peaches. I've never needed to spray them. I planted my first peach tree here over 14 years ago.

I harvested and ate another satsuma tangerine today. Yum! Only five left!

The first frost of the season hasn't arrived here yet, and none is forecast in the next seven-days or nights--but we're getting close...). I'm planning on moving a few more of the citrus into the greenhouse this weekend. I need to re-pot the largest lemon tree. That old plastic pot it's in is really starting to crumble and split.

Deleted. Double post.

Yesterday I moved the second orange tree into the greenhouse. Today I moved the second lime tree into the greenhouse. Tomorrow I'll move a lemon tree in there. I'm still taking things pretty slowly after that hernia operation six weeks ago. The hand truck helps a lot moving these potted plants about 40 ft from the porch/deck to the chain link fence gate, and at least another 100 ft around the fence over to the greenhouse.



Once two of the three lemon trees are moved in here, I'm going to buy another 1000 ladybugs and release them in here. The third lemon tree will get re-potted soon and will come into the house to serve as a Christmas tree again.

Still no overnight freezing temps in the 7-day forecast...

Today I moved the sixth citrus tree into the greenhouse and bought 1500 ladybugs since there are still some aphids on them. The ladybugs will arrive in about a week. I mounted the ladybug house in the greenhouse, seen on the lhs of the picture



I sprayed off most of the aphids from each tree (with just water) before moving them in here.

[PeakOiler]

Today I repotted my oldest citrus tree--a lemon. The old plastic pot had begun to split around the top, and I was concerned that it would split further as I move it into the house for the winter. I still have to fill the pot with a little more soil and water again.

This is my Christmas tree.



A freeze is likely later this week.

I harvested my last satsuma tangerine of the season today.

[PeakOiler]

So far the ladybugs are doing a great job devouring the remaining aphids on the citrus in the greenhouse. Applying the beetles in an enclosed space is the way to go. There are no ants to impede the ladybug attack.

I think these two need to find a leaf-room!

I'm always inspired by your posts, PeakOiler.

Thanks Ludi. You've been helpful with your posts too.

There are still some ladybugs in the greenhouse. I hope the weather doesn't get too cold this winter. I'm using a couple electric lights in there at night for a little warmth (as needed.) I'm planning on setting up the chimeneas near the greenhouse soon.

The one and only pink grapefruit this season is almost ready to be picked.

All three lemon trees are covered with flower buds.

It seems like it's been a cold winter so far. Seems like we've been using the woodstove a lot more earlier in the season this year, but of course that doesn't mean it will get a lot colder. Just maybe more cold days, but not colder days, if you know what I mean. I think your place might be a little warmer than ours, PeakOiler, even though you're farther north. We're in a little valley, a bit of a frost pocket.

[PeakOiler]

Yes, Ludi, it has been colder than normal so far this season. KBMQ in Burnet recorded 3-4 new record lows this season so far.

My lemon Christmas tree:



Instead of a pine smell from a dying tree decorated for the season, I smell lemon blossoms from a living tree.


One of those spheroids is the last lemon of the year. I'll pick it on Christmas day.

[Ludi]

That's adorable!

[PeakOiler]

I harvested the one and only pink grapefruit of the season yesterday. 336 grams (3/4 lb) It is about 3.5" in diameter.

The aphids were not kind to the young grapefruit trees this last season. The " I'm not quite dead, I'm getting better" young grapefruit tree is making a good comeback so far and may produce this next season. (I hope).

OK, it's almost time for spring. PO, how do you prune your trees? My peach tree is starting to get a little tall - should I keep the growth short and bushy, or let a central leader get some height on it?

Pruning
The main goals of pruning are to maintain tree form to an open center which facilitates light penetration and air circulation, and to partially control crop size by selectively thinning out fruiting wood. Peach trees bear fruit only on one year old wood. Dormant pruning is an invigorating action which results in a healthy canopy to produce the current season's crop and allow for ample production potential for the following year. Another pruning objective is to lower the fruiting zone to a height which can be hand-harvested from the ground. Topping trees at 7 -8 feet usually accomplishes this objective because the weight of the crop will bring limbs down where the fruit can be easily reached. Additional objectives of pruning are to remove dead or diseased shoots, rootstock suckers, and vegetative water sprouts from the center of the tree. When thinning out fruiting wood, remove old gray-colored, slow growing shoots which are not fruitful and leave one-year-old, red, 18 - 24 inch bearing shoots.

I didn't prune my trees too much when they were young, just the lowest shoots, suckers, and dead twigs. I did a more serious pruning last fall. "Topped" a couple of them.

The record low freezing temps recently damaged the citrus in the greenhouse. I may lose the two lime trees. We'll see...

So sad!

[PeakOiler]

Nearly all those lemon blossoms shown earlier are gone, as well as most of the leaves...

I have some serious improvements that need to made to the greenhouse...

That extended freeze was terrible. It's difficult to plan on weather that breaks 20+ year old records...

[PeakOiler]

It's getting pink around here. All 13 of my peach trees have either blossomed or are about to. It may be another record breaking peach harvest season this year. We'll see...

Meanwhile, I pronounce my two potted lime trees as dead. The extended freezing temperatures in early February was just too much for them in the greenhouse. I now wish I had not put both of them in the greenhouse, but instead had brought them into the house. I had room. My mistake.



The red line shows the high temps, the blue line shows the low temps.
The circled data points in the graph above indicate record-setting temperatures.

If my tree investment efforts becomes positive this year due to a productive peach harvest, I'll get another lime tree.

It's a shame I can't eat peaches now that I have type II diabetes. Well, I may cheat and eat one...

[PeakOiler]

And now for something completely different...

Today I moved the two potted grapefruit trees outside onto the deck. They're both putting out new leaves. The four satsuma survived the winter. So did the two orange and two of three lemon trees. The tangelo produced it's first small (68 grams, edible) fruit a couple weeks ago. Delicious!

The 13 flowering peach trees are doing just fine, but we sure could use some rain. Most of Texas is in a drought again...

I started another batch of peach wine using frozen peaches from last year's harvest. (Kept frozen in a solar powered freezer, btw.) I'll let y'all know how it comes out. I'll be giving/trading most of the wine away, however, since I'm to avoid alcohol (as much as possible) due to the change of diet. Damn! Diabetes sucks!

The potted pineapples growing in the living room are fine. I gave one of the largest plants to a friend for his birthday. The pineapple fruit shown (in another thread) is getting bigger. I didn't give that pineapple plant to my friend! "That one's mine", I said. lol
Damn! Another food I'm not supposed to eat anymore...
If that fruit matures and I harvest it, I'll eat that pineapple just a little at a time. Like over months...

I'm glad I planted pecan trees. Now that's a food I can still eat.

My tropical Peach fruited over summer (December) and is already in blossom again.(March)
Its done this before when I get 2 crops in one year.
I live in a Subtropical climate (southern Hemisphere),its all new to me as I have only grown peaches in temperate climate before.
I'm not complaining though.
If you want virtual year round fruit in the subtropics,try a Acerola its almost never stops fruiting
Massively high in vitamin C
