Some kales are better suited to perennial than others. I have some tree collards, that should last 5 years. The suggestion is to cut off the flower stalks as they are forming and root them as cuttings. I tried the same with my lacinato kale in it's second spring and so far so good. I'm not seeing roots, but they survived me going to Japan for 3 weeks and only intermittent care from friends. The flowering shoots are the tastiest part of the plant, as far as I am concerned. Garlic - kale flowers - olive oil - lightly sautee with whatever else is on hand and add to pasta - yum! I have 4 kinds of kale, the tree collards, the lacinato and a classic curly greenkale all in their second spring, but this SoCal. The winter sure won't kill anything, but the summer does.

Yes ma'am, Annabeth. The yellow genes in Teas and the associated Tea-Noisettes produces some wonderful plants, but they can be SLOW right out of the gate and they HATE hard pruning. They, in particular, require all that stored food in the thick, old wood to explode into the growth you expect from them. It takes them what seems like an overly long time to create the roots and produce the wood they require. Add cooler temps, reduced sun, perhaps drainage issues and any disease or insect inhibitors and you have some real performance issues. Personally, while I love the idea of own root plants, for those types budding IS preferable because of the increased, artificial vigor the root stock adds to the mix. Even budded, they improve and benefit from the TPN treatment. Keeping them canned while you do it speeds things along greatly due to the increased cellular activity of warm roots and warmed sap, as well as the increased bacterial activity in warmer soil. From what I've read, most soil bacteria are fairly dormant in soil temps less than 70 degrees F, so the higher heat (as long as it isn't to the cooking levels) of canned roots helps push them even faster than when in the ground. That's also why standards on suitable stocks (read IXL where the sap flow is tremendous, as opposed to Huey, which is today's standard, and whose flow rate significantly slows as the trunks get longer), tend to grow a lot faster and flower earlier and often longer, than traditional bushes. Putting something weaker on an IXL trunk can push the dickens out of it! Susan, what would I do to push something like I did now? Whatever the size pot the plant is in now, presuming the roots are nearing or have reached the point of benefiting from being up sized, I'd go to the next size pot. I don't like jumping sizes because the roots seldom knit the whole together sufficiently to prevent the root ball from disintegrating when either up sized or planted. Going from a one to a two, then to a three or five, followed by a seven then perhaps a fifteen gallon, gives the roots enough time and warmth to infiltrate the soil ball and create a tight whole with good structural integrity. I hate when I tip the ball out of the pot and the danged thing bare roots on me. I would (and am) use whatever potting soil I find beneficial for my climate and gardening style. Here, because of the high evaporation rate, I use Moisture Control Miracle Grow. I like the timed release fertilizer in it, though be aware that time released anything, releases faster in higher heat. That's why they print "up to three months" on the labels. Make the soil hotter and it leaches out and breaks down faster. Pot the plant in the next size larger can in the soil you prefer. I like to mix organic and inorganic fertilizers. Organics feed the soil, inorganics feed the plant quicker and the additional nitrogen feeds the active soil bacteria so it doesn't rob nitrogen from the plant when it needs it most. Mixing them gets the soil cooking, allowing both the plant to make use of all the nutrients as well as the soil bacteria to do its thing and digest the organics, turning them into the salts which are absorbed by the plant roots. Nitrogen leaches from the soil in water. Potassium and phosphorus tend to stay put where they are, requiring roots to find them for absorption. With any heat, you should start noticing growth pretty much all over the plant in fairly short order. Keeping the flower buds pinched off stimulates an even higher level of growth activity. After several weeks, if the plant is continuing to push the growth, you might consider using a diluted foliar feeding of liquid fertilizer. It can be fish emulsion, Miracle Grow or whatever you prefer. If the instructions state to use a tablespoon per gallon every two weeks, consider using half that strength at twice the frequency. Say half tablespoon in a gallon, weekly. Plants will absorb nutrients through their leaves and canes as well as through the roots. I found in the Valley heat, hosing the plants off to rinse off dust and pollution, watering them well and allowing them to drain and air dry, then following that with a foliar feed pushed them like crazy. In that climate, at that time of the year, diseases weren't an issue. A film of water on the leaf surface won't cause disease. It can actually help prevent them. The spores germinate on dry leaf surfaces, in the presence of humidity when the temperatures are conducive for them to germinate. Rinsing off your foliage can actually help hydrate the plant and remove residues from smog, dirt and other sprays. Some of the most glorious foliage I ever grew were in the old Newhall garden where evaporation was extreme. There was constant wind, constant sun, high temperatures and without the extra water, leaves tended to be smaller and more stressed looking. Running an overhead, oscillating sprinkler on them for a good soak resulted in enormous, clean, healthy foliage on husky, amazing plants. Yes, I know, not everyone has those conditions and these days, none of us can justify nor afford that kind of water. Adjust it to what is appropriate for your conditions and water situation. The hotter, dustier and drier your garden, the more the plants will benefit from overhead watering. Just do it early enough to allow the added humidity to dry before night and you should see benefits from it. I'd had spider mite problems for the longest time when still in the Granada Hills garden and I read and followed all the Organic Gardening suggestions to the letter. Marigolds not only did NOT repel them, all the marigold plants were tented with their webs. Breaking all the rules, eliminating the plants they seemed to prefer and drenching the plants tops and bottoms with a water wand cleared the miserable things up in short order. The roses seemed to love it, too. You have your plant up sized, in the soil of your choice and are feeding it with your food (s) choice. Place it where you feel it receives the best air flow, light, heat, wind protection and can benefit from your focused attention to make sure it has the water it needs. Permitting it to dry out will bring all activity to a halt and can result in parts of the plant dying back, which you know from your normal gardening. If you're trying to create a spectacular plant in a shortened time, it will require more of your attention. A few minutes a day pouring over it to check its progress and attending to any new needs shouldn't add enormously to your gardening time. It will teach you a great deal while you're at it, too. Watching what the plant does in response to what you do is quite educational and a lot of fun! You may stop this treatment when you determine it is appropriate for what you want/need the plant to be as well as when you feel is appropriate for your climate. I can almost do it year round here in Encino as we will never have snow and very, very seldom have any weather cold enough to do any real damage. More severe climates will require tweaking timing and amounts to adjust for the beginning and end of their growing season. It serves no good to keep providing all the resources necessary to push all this lovely growth when a killing frost or several feet of snow are expected while it's still soft. That is pretty much what I did at Limberlost and The Outdoor Room to produce those specimen quickly. You may do any part of it, or all of it to suit your time, energy, interest, checkbook, etc. It does work and it's a very fun, interesting experiment which will teach you more than you ever expected it to. You'll be taking one (or more) of your plants and basically putting them under a microscope. You'll see concentrated results from your actions as the plants respond faster to all you do to and for them. All you're really doing is what specialty growers do to produce the photogenic examples to entice people to buy their wares. If you expect to hold an open garden, or have guests planned for a party or wedding in the garden later in the season, you can really push the maturity of points of interest this way. Without a greenhouse, it's the best way to produce these kinds of results. And, it CAN be a whole lot of fun! (I know, I need to get a life! LOL!) Kim

Alex- Re: "Now, I have also heard that in certain cases, the rootstock is left on and even if it has no foliage, that it will still be beneficial to the plant's health and it is about this that I'm curious." -I have never heard this. A shoot without foliage eliminates photosynthesis and nutrient cycling, thereby cancelling root/shoot growth benefits. -A stub might be better in many instances rather than a near-flush-cut wound depending on the plant's ability to heal and the site of CODIT (Compartmentalization of Decay in Trees). If the understock is similar diameter to the graft, or larger, the ability of the remaining understock to heal the wound following complete removal of the understock could be limited and could invite additional infection or decay. As such, if you remove the understock to a stub 1-2" above the graft union, then allow the grafted plant to develop larger, then remove the stub completely after the grafted plant is 2x or more the diameter of the stub, it will more completely heal and cover the graft union. "Which plants might be good candidates for this sort of treatment, and why would you do this rather than leave on a full branch with leaves (one which is not shading the scion of course)? Why would you "remove the understock gradually" rather than leave a branch on until no longer needed and cut it off all at once?" -The more understock foliage you maintain, the larger the understock diameter will be. You don't want a massive diameter, because when you ultimately remove it, you want the wound to heal quickly. By removing the understock gradually on graft-sensitive varieties, you still maintain the beneficial root-shoot interactions, but keep the caliper of the understock minimized. -Good candidates for this have been mentioned above: true miniatures, many golden or variegated varieties. -Timing related to removal of the understock: this depends on growing conditions, health of the plant overall, etc. Dax's advice on when you can remove understock for a miniature is good, I might upgrade from a "golf ball" size to a "tennis ball" size. For golden/sensitive varieties, it depends on health, growth rate, sun/shade, etc. -Brent

The water/alcohol mix has always been my 'go to' for mites and aphids, but the neem oils will really help. Keep in mind that it doesn't ......... I'll just copy paste something I wrote a few years ago: Neem Extract as an Insecticide In India mainly, but also Asia and Africa, grows a tree all plant enthusiasts should be aware of, Azadirachta indica, commonly known as the "neem" tree, and a relative of mahogany. Extracts from the tree’s seeds contain azadirachtin, a relatively safe and effective naturally occurring organic insecticide. Let me preface the comments following, by reminding you that the terms "naturally occurring and/or organic" do not universally mean safe. Pyrethrums, rotenone, and even the very dangerous nicotine are all organic insecticides that should be handled with great caution. Neem extracts, on the other hand are very safely used in a wide variety of cosmetics, as a topical treatment for minor wounds, as an insecticide in grain storage containers, bins, and bags, and a whole host of other applications. Neem is very safe for use around birds & mammals. I'll limit this discussion to its use as an insecticide. Neem works in many ways. It is effective both in topical and a systemic applications. It is an anti-feedant, an oviposition deterrent (anti-egg laying), a growth inhibitor, a mating disrupter, and a chemosterilizer. Azadirachtin, a tetranortriterpenoid compound, closely mimics the hormone ecdysone, which is necessary for reproduction in insects. When present, it takes the place of the real hormone and thus disrupts not only the feeding process, but the metamorphic transition as well, disrupting molting. It interferes with the formation of chitin (insect "skin") and stops pupation in larvae, thus short-circuiting the insect life cycle. It also inhibits flight ability, helping stop insect spread geographically. Tests have shown that azadirachtin is effective in some cases at concentrations as low as 1 ppm, but some producers use alcohol in the extraction of neem oil from plant parts which causes the azadirachtin to be removed from the oil. Some products touting neem oil as an ingredient actually have no measurable amounts of azadiractin. I use what is referred to either as cold pressed or virgin neem oil. You may also occasionally find it referred to as "raw" neem or "crude" neem oil. Neem oil is most often used in an aqueous (water) suspension as a foliar spray or soil drench. Commonly, it is diluted to about a .5 to 2% solution, but the suggested ratio for use in container plant culture is 1 tsp. per quart of warm water. A drop or two of dish soap (castile or olive oil soap is best) helps keep the oil emulsified. The mixture is then applied as a mist to all leaf and bark surfaces and as a soil drench to the tree's root system. It should not be applied as a foliar spray on hot days or in bright sun as leaf burn may occur. Remember to agitate the container frequently as you apply and do not mix anymore than you will use in one day. Neem breaks down rapidly in water and/ or sunlight. Some users of insecticides feel the need to observe the instant results of their efforts in order to be convinced of the effectiveness of what they are using. The application of neem derivatives does not provide this immediate gratification. There is virtually no knockdown (instant death) factor associated with its use. Insects ingesting or contacting neem usually take about 3 - 14 days to die. Its greatest benefit; however, is in preventing the occurrence of future generations. It is also interesting to note that in studies it was found that when doses were given, purposefully insufficient to cause death or complete disruption of the metamorphic cycle, up to 30 surviving generations showed virtually no resistance/ immunity to normal lethal doses, so it appears that insects build no ‘resistance’ to azadiractin. I have been using neem oil for five years as both a preventative and fixative and have had no insect problems on my container plants. Applications of cold-pressed neem oil are most effective for use on mites, whitefly, aphids, thrips, fungus gnats, caterpillars, beetles, mealy bugs, leaf miners, g-moth, and others. It seems to be fairly specific in attacking insects with piercing or rasping mouth parts. Since these are the pests that feed on plant tissues, they are our main target species. Unless beneficial like spiders, lady beetles, certain wasps, etc., come in direct contact with spray, it does little to diminish their numbers. Neem oil does have an odor that might be described as similar to that of an old onion, so you may wish to test it first, if you intend to use it indoors. I've found the odor dissipates in a day or two. As always, read and follow label instructions carefully. Neem oil can be purchased from many net or local sources. My favorite brand is Dyna-Gro, pure, cold-pressed neem oil. Al
