My Collection of Lapageria by Noel Most of my experience with growing Lapageria rosea is based on container cultivation at my home in Napa, California. Some of the following recommendations may be specific to my situation but, for the most part, I think this information will be useful in cultivating the plant in a variety of situations. Exposure All of my plants (with the exception of one plant) are grown in clay flowerpots along the southwestern side of my house, against a stucco wall. They are shaded during the summer by a very large sycamore tree and receive very good indirect morning light and strong, dappled sunlight during the afternoon. This is more sunlight than generally recommended for Lapageria; however, they do not burn and produce strong, hard growth. My only caveat would be to try to maintain cool temperatures around the roots. However, my plants have seen 100+ degrees with no ill effect. New growth will wilt at this temperature in full sunlight, but it quickly recovers when the sun goes down or the temperature drops. I will hose my plants off in hot weather if I'm home, but this is probably not really necessary. |

Watering
My plants are watered with water from the tap which, in Napa, is both
alkaline and very heavily chlorinated. I water daily during the summer months;
during the winter the rains keep the plants well-watered. The ideal is to keep
the compost moist, but not soggy. Compost My compost is a commercial soilless mix (I try to buy an organic acid mix),
which I usually amend with some fine redwood bark (seedling orchid grade) and
perlite (though I don't like the way the perlite rises to the surface). I
usually add spent mix from my pleoine collection (which is composed of orchid
bark, sieved long-fiber sphagnum, perlite, beech leaves, charcoal, and peat
moss) as a method of both getting rid of it and keeping the Lapageria compost
from becoming too tight. I add Osmacote and fresh pig manure (which appears to
be very mild in the case of potbellied pigs!). The spent pleoine mix might
contain some bone meal as well, if any remains after a season. Containers All of my plants are in clay pots, with a piece of screen placed over the
drainage hole to discourage slugs. The plants still manage to push roots out
through this and I continually shift the pots to keep them from rooting into the
ground. Most of the root system moves to the bottom third of the pot, with very
little surface activity. I repot irregularly, and have moved both dormant and
actively growing plants. DO NOT REMOVE OLD SOIL FROM THE PLANT AND TAKE EVERY
PRECAUTION TO LEAVE THE ROOT BALL UNDISTURBED!!! I have received bare-rooted
plants which took up to a year to settle down. Plant deeper (as with a clematis)
rather than shallower and the plant has a tendency to rise up out of the pot.
Also, be very careful of new growth, which is quite brittle, and which tends to
emerge along the rim of the pot (just where your pick the pot up). If a growth
snaps off, resist the temptation to "tidy it up" by cutting it off. It
could very well re-sprout, either from the base or further along the emerging
stem. Stems also wither and die off for no apparent reason. Feeding I tend to overfeed, but my plants look all the better for it. I use a
half-strength formula and feed once a week in summer. I use a variety of foods,
including Miracle Grow, Maxicrop, and fish emulsion. However, I try to stay on
the acid side. I also used iron chelate as Lapagerias have a tendency toward
chlorosis. Foliar feeding is highly recommended (I use the same dilution, plus a
very small amount of soap if bugs are present). The one plant which I do not
regularly foliar feed looks nowhere near as nice as those which are, even though
it is growing in extremely rich soil. I decrease feeding around October, and
feed only about twice a month (if I remember) in the winter. When strong new
growth commences in late January, I begin to feed on a more regular basis. I
think Lapagerias are extremely greedy feeders, and you can certainly push them
to grow with food. As I mentioned in Compost, I add Osmacote and pig
manure when I repot. Propagation Seed Propagation I have never propagated Lapagerias myself, though I have raised a number of
seedlings and barerooted plants. Seedlings are not fussy, and I have even bare
rooted a pan of seedlings (to tease them apart) with no ill effect. Vegetive Propagation My friend Rennie Moffat had very good results with cuttings (up to 90%), and El Vergel uses the technique called serpentine layering using leaders which have flowered. Sarah Wickander is also quite successful with both cuttings and divisions. Click_here to learn about Rennie's method of taking cuttings and layering. The Elbert Reed article also contains some guidelines on vegetative reproduction.Pests Snails and slugs are a Lapageria's greatest enemy, especially the tender new shoots. I keep snail and slug bait around my plants at all times, changing brands frequently, and also have ringed the lip of some pots with copper tape. I'm not sure how effective this copper tape really is, and would certainly not rely on it alone. The new growth is also subject to aphids, which I treat with soap, and the older grown can suffer from mealy bugs, thrips, and mites, which I treat with soap, summer oil, and hand picking. Leafcutter bees can be a problem, but I'm not willing to spray and snailbait is the only really toxic material I use. I'm currently trying out a new miticide from JH Biotech. Inc.. which is composed of cinnamon, garlic, and cottonseed oil. I'm not sure how effective it will be, but it sure smells good! I've used one of their products, Promote, in the past as a growth enhancer on seedlings and plants which are lagging, and have been very pleased with the results. I'll keep you posted about the miticide. |
