Question for Dr. Manners re node count
Comments (23)ok what about when a grafted tree blooms when it is small and the branches are not very long. will it continue to bloom at those lower branch locations even when it is quite old in essence having the whole tree producing fruit, the lower and top end? or does the node count change to higher requirements as the tree gets larger for it to produce fruit at? nero, A grafted tree is created with a mature scion. The scion never forgets its node number....could be something like, who knows?, 100,000 or a gazillion, depending on where it came from. Any branches that shoot from it will begin their node count at the scion's count, if that makes sense. ANY branches that come from it will be capable of bearing no matter how large or small the tree. To my knowledge branches cannot revert back to juvenile once their mature. Kind of like have you ever seen English ivy growing up a tree, then all of a sudden it matures into a more shrubby-like thing? It grows branches and the leaf shape changes. If you take cuttings of this mature growth, it will retain its shrubby character and not revert back to its juvenile viney character....See MorePotting My First Citrus Tree!
Comments (7)A few words of advice about Advice. Be absolutely sure whomever you talk/email/forum visit with when getting advice knows your citrus is in a container. If the guy at the garden center says "well the container should be the same as in the ground, citrus can even grow in plain dirt. So xxxx product should work." run away -- as fast as you can and forget everything that person told you. When I started I got so much advice (nursery, garden centers, friends, books, etc) I thought I retained everything quite well. However, I mistakenly mixed in-ground vs. container suggestions and the end result wasn't good. It took some mistakes and reading on this forum and the Container forum. As has already started, you'll get conflicting advice about peat moss, special citrus soil, sand, wood chips, bark, gypsum, dolomite, compost, mulch, etc. Just remember, it's not like a stew, you can't take a little of everything that's "good for citrus" and have it work (that was my mistake). It's because container citrus are much less forgiving than in-ground. Keep in mind there is a difference between "ideal advice" and "practical advice" and whether that's for the tree or the gardener. But you can do whatever you want. It's very easy to give canned advice using our own assumptions of the situation. You know your situation best and you'll learn more from the outcomes of your own decisions than you will memorizing what others are telling you. Your Questions in Particular: 1) How big -- it depends on the rootstock. Lemon Drop I think is mix of kumquat / lemon that tastes a bit bitter sweet. You need to find the name of the rootstock, or at least search the tree and container for any labels/tags that may say "dwarf" or "semi-dwarf", if it doesn't say either it's likely not a dwarf and I wouldn't plant this tree in a container (making the entire thread moot) ;-) Ask where you purchased it for the exact name of the roostock to find out. A rough estimate in container: true dwarf: 4-6', semi-dwarf: 5-8' depending on pruning. 2) Yes that 22" x 2' deep terra cotta container will ultimately be big enough. That's only a few inches smaller than a half wine barrel. You CAN put your tree in that huge container, but the ideal method is to upgrade the pot size every year or so. If you do use your 22" container, it will provide more protection in the freeze, but know it will tend to "hold" on to more water than a small tree can use. But many people do it, you just have to be more careful watching your tree's health. Other than that, I don't know much about freezing temps except for buying the frost blankets to cover it, watering deeply on cold nights, using lights, etc. 3) If you have "citrus fertilizer stakes" they are for in-ground and not containers. 4) The ideal: pluck off that fruit sorry :(, wait a few months until after the growing season, and then pot it in container a few inches larger than the current. Of course, fertilize and water until then. Soil Your soil choice in a container is critical. The technical stuff is about drainage, aeration, ph, etc. But practically because it determines how much/often to water, fertilize, and certain soils compact sooner than others, which means you'll need to replace it sooner. Using a good draining soil is even more critical if you put a young citrus in an overly large container. However, short and simple: buy special Palm/Citrus soil w/fertilizer added (big box stores have it in 8 qt bags for about $6). You're probably fine with ONLY that soil. Add a couple inches of any mulch on top (except not directly on the trunk). Buy a citrus fertilizer in pellet form that say "contains micronutrients" on the front and follow the directions for using in container (about 90% of the directions is for in-ground, there is usually a small paragraph at the bottom for containers). And you're good for a year if watered well (over-watering will kill it quickly) and protected from the severe elements. This may not be "the best" but it's an easy task for beginners to keep the citrus healthy enough to buy you time you learning about optimal care requirements. Re-potting and Roots Lastly, I didn't realize the down-the-road work involved in containers. Not to scare you away, but be prepared for work every year or two: replace the container soil, upsize the pot, prune roots, etc. How often depends on the soil you picked above. More Help There is a TON of valuable information already here in these forums and the net. You will want to learn more than my long-winded advice can provide. Search Terms: Caring for Citrus, Pruning Citrus, Fertilizer. There is a very good series of posts, albeit technical, titled "Container Soils - Water Movement and Retention" by Tapla--Al if you're inclined. http://forums2.gardenweb.com/forums/load/contain/msg010937265978.html?143 Caring for citrus is very standardized but there may be important caveats depending on where you live. That's why I didn't provide links for Citrus care. For example, I live in Fresno, CA and University of California Davis has excellent information about Citrus in California, even specifically where I live. There are different pests here, and the rootstocks for trees I buy may not be the same as in your area. Have fun and hope you love citrus as much as I do!...See MoreContainer Citrus potting mix?
Comments (14)I like Just Fruit's citrus trees and have bought a bunch of them, but I don't agree with their "Most commercially available potting soils are fine for citrus, or you can mix 1 part clean sand, 1 part peat and 1 part pinebark" at all. That is going to lay too wet for good citrus growth in my opinion. I haven't tried Turface or crushed granite as I haven't been able to find a local source for either of them. I'd really like to try them though and will if ever I get the chance. In the past I've used pine bark nuggets in the half-inch range mixed four parts bark to one part spagnum peat. This works very well for for both aerosity and water retention. My only complaint with it is that it needs replacing after about a year more or less. Once it breaks down past a certain point it starts holding too much water. My present perennial media mix is half-inch treated coconut husk chips and ground coconut coir about 3.5 parts chips to one part coir. This has given me really good aerosity while still maintaining good water retention. In the terra cotta colored plastic pots I find I need to water about twice a week in the hot parts of the year (full sun), less if it has rained a lot. My oldest tree has been in the same media for nearly three years now and come spring will have to have it replaced. I'd really like to find a largely inorganic media that would last even longer which is why I want to experiment with the Turface and maybe horticultural charcoal. The tree still has to have pot maintenance periodically though to either be moved into a larger container or have some root pruning done so the permanent media only gets you so much. I haven't used much slow-release fertilizer as the Osmocote and store brands that I've found so far all tend to release too fast in the hot part of the year. Some of y'all have mentioned a Dynomite brand that I'm going to look for to give it a try. Mostly I use Scotts soluble 20-20-20 with minors with some added magnesium sulfate (Epsom salts) once a month. Occasionally I'll add a liquid metals product to the mix if the leaves start looking a little pale. Even with forgetting to fertilize over the summer we've still got more Key and Tahiti (Persian) limes than we can use and the Eureka lemons are starting to color up now as well. If I could find some way to fend off the leaf miners and grasshoppers without going to systemics the trees would even look pretty by the time fall rolls around. It's frustrating to get to this time of year and have them look like they do because of the bug damage. .....Alan....See MoreQuestion on node theory and blooming of citrus seedlings.
Comments (21)Jenelle Vallee , lemon seedlings generally take anywhere from 5 to 10 years or more to bloom, depending on environment and length of growing season. They usually grow very vertical and must get quite tall. If you trim it before it blooms, it will just keep putting out juvenile growth (not able to bloom). So you may have to allow your lemon to get 6 to 9 feet high or more to achieve 'mature growth'. This is another reason why most people grow grafted trees, or trees grown from mature-wood cuttings. They bloom at a MUCH smaller size and much sooner! Fortunately, you're not growing an orange or grapefruit, from seed as those can take 15 years or more!
