Magnificent Manzanitas 2011

  1. 1. Out of the Wilds and Into Your Garden Gardening with Western L.A. County Native Plants Project SOUND – 2011 (our 7th year) © Project SOUND
  2. 2. Magnificent Manzanitas C.M. Vadheim and T. Drake CSUDH & Madrona Marsh Preserve Madrona Marsh Preserve December 3 & 6, 2011 © Project SOUND
  3. 3. The genus Arctostaphylos  In the Heath family (Ericaceae)  Includes the Manzanitas and Bearberries, blueberries  Manzanitas occur in the chaparral of western North America, from southern British Columbia through much of northern and central Mexico.  The three species of Bearberries have adapted to arctic and subarctic climates, and have a circumpolar distribution in northern North America, Asia and Europe. © Project SOUND
  4. 4. Why do people fall in love with Manzanitas?  Showy, sweet-smelling flowers in winter/early spring  Evergreen foliage  Red bark  Interesting, architectural growth patterns  Edible fruits/medicinal leaves  Attracts hummingbirds, native bees & butterflies  Because they’re rare in the wilds  Because they are a part of California’s unique wild heritage © Project SOUND
  5. 5. Whatever the reason, people want to include manzanitas in their gardens…. And that can be a challenge for those of us living in western L.A. county © Project SOUND
  6. 6. Success with manzanitas begins with choosingthe best species or cultivar for your conditions © Project SOUND
  7. 7. Tailor the manzanita to your conditions (rather than the other way around)  Soil conditions:  Texture/drainage  pH  Size: height & width/spread  Growth pattern/speed  Light/temperature  Water regimen  Aesthetics:Fortunately, there are more than forty species of Arctostaphylos inCalifornia not to mention all the cultivars, subspecies and hybrids. © Project SOUND
  8. 8. Many species require well-drained soils  Soil texture/Drainage Soil type Approximate time to drain Hard-pan or days sodic soils Clay 3-12 hours Loam 20-60 minutes dig hole 1 ft x 1 ft Sandy Loam 10-30 minutes fill with water and let drain Sand cant fill the hole, fill hole again, measure drains too fast time for water to drain © Project SOUND
  9. 9. Many manzanitas like a slightly acidic soil  Most manzanitas originate in areas with more acidic soil due to:  Higher rainfall  Effects of chaparral/woodland plants  The rock material from which the soils were derived  Our local garden soils tend to range from 6.5 to 7.5 – and some may be as high as 7.8+Soils under pine trees and oaks will be more acidic © Project SOUND
  10. 10. So, you really should test your soil pH if you want to grow manzanitas  A simple garden soil pH test kit is adequate for the job – no need for fancy equipment  If your soil is Alkaline (pH > 7.5) consider planting in a large pot  If your soil is neutral or slightly acid (pH 6.0 – 7.5) choose manzanitas that like a slightly acid soil and use an organic mulch  If your soil is acid (pH 5.0-5.9) you can plant even those that need acidic soils © Project SOUND
  11. 11. Can’t I just amend my soil to lower the pH?  Actually, it’s not that easy:  Takes a lot of effort to lower soils pH – and you have to keep doing it because pH keeps ↑  Acid fertilizers also increase the soil N levels – often too high for CA native plants  Chemical amendments:oratingAmendments.aspxIf you’re acidifying 1000 sq ft of  sulfur or iron/ammonium/soil with sulfur, a 1.0 change in aluminum sulfatepH (from 7.5 to 6.5) requires 11pounds of the product for sandy  Natural amendments: pine straw;soil and 23 pounds for claylikesoil. oak leaf mold  ? Coffee grounds/acid compost © Project SOUND
  12. 12. Size matters: most Manzanitas eventually want to grow to their natural size © Project SOUND
  13. 13. Manzanita species grow from < six inches (some coastal species) to twenty feet tall (many interior species). &return=s_aP © Project SOUND
  14. 14. Don’t forget the width Arctostaphylos rudis "Burton Beauty Manzanita". A. refugioensis © Project SOUND
  15. 15. The right plant, grown correctly, will live for more than 100 years (especially the larger forms). © Project SOUND
  16. 16. Let’s say you want to replace an old tree with a large manzanita © Project SOUND
  17. 17. Big Berry Manzanita – Arctostaphylos glauca© 2008 Gary A. Monroe © Project SOUND
  18. 18. Bigberry Manzanita: shrub or tree  Easy-care shrub for slopes; good for erosion control  Specimen shrub; needs little pruning  As a small shade tree  As a key shrub/tree for the habitat garden: bees, butterflies, birds, humans © Project SOUND
  19. 19. Why choose Manzanita cultivars?  Because they have better size, shape, color, etc.  Because they often are better adapted to garden conditions (and therefore more likely to thrive in your garden)  Garden tolerance - cultivars are often more tolerant of:  A little extra water  Soils that are not perfectly drained  Heat and cold  Salinity and higher pH © Project SOUND
  20. 20. Arctostaphylos glauca ‘Los Angeles’  Source plant: originally in the area of Mullholland Hwy. and Kanan Rd.  Smooth red bark and clean shiny foliage with pink- white flowers make the plant quite attractive.  Locally native – tolerates sandy soils of western L.A. County © Project SOUND
  21. 21. Arctostaphylos glauca ‘Frazier Park’  From Frazier Park/ Mt. Pinos region ~ 5000 ft.  The form is low/dense for a Big Berry Manzanita.  Foliage is pale green, a glaucous green, making it appear whitish-bluish - beautiful accent plant in a garden. © Project SOUND
  22. 22. Arctostaphylos glauca ‘Margarita Pearl’  ? Big Berry manzanita (glauca) or a hybrid between A. glauca and A. wellsii  Very large flowers and berries – good for edibles garden  Foliage is a bright grey on new growth and dull grey on old growth – lovely color © Project SOUND
  23. 23. Arctostaphylos glauca ‘Ramona’  From San Vicente/Ramona area (San Diego Co.)  Red bark, a very open form, clean glossy foliage. The plant looks almost artificial  Use as a specimen with lower green manzanitas and ceanothi under it, or as an elegant eight to ten foot hedge in a chaparral planting.  Ok in soils of pH 7.8, and might even be ok in pH 8. © Project SOUND
  24. 24. Arctostaphylos ‘Canyon Blush’  Arctostaphylos glauca hybrid from a chance seedling in the Santa Barbara Botanic Garden.  Red-flushed new foliage and blush pink flowers  4’ tall by 20 ft wide; climbing/ trailing form  Quite effective as a sprawling, large-scale groundcover, or cascading down a slope.  Use drip irrigation in place of overhead watering to reduce spread of this disease. © Project SOUND
  25. 25. Allelopathy: chemical warfare in the garden  Chaparral plants tend to ‘exclude’ other plants:  Shading or crowding out  Producing chemicals that are toxic to plants or seedlings  Some common trees/large shrubs that practice chemical warfare: Manzanitas/Bearberries   Walnuts  Oaks  Sycamore  California Bay laurel  Cottonwood  Non-natives like Forsythia, Tree-of-heaven, Black locust and Eucalyptus © Project SOUND
  26. 26. Common Manzanita – Arctostaphylos manzanita © Project SOUND
  27. 27. Common Manzanita – Arctostaphylos manzanita  Central & northern California - Contra Costa County north to Humboldt, Trinity, and Shasta counties; and from the foothills of the Sierra Nevada in Shasta County south to Mariposa County.  On ‘dry’, well-drained, sunny sites in Ponderosa shrub forest, California mixed evergreen forest, Northern oak woodlands, Chaparral, Montane chaparral,3454,3492© 1994 David Graber © Project SOUND
  28. 28. Common Manzanita: large size  Size:  6-12+ ft tall – as tall as 20’  4-10 ft wide  Growth form:  Large evergreen shrub/small tree  Open, upright habit – many long twisted trunks give it an umbrella-like shape  Peeling red-brown bark  Foliage:  Bright green to slightly blue- green  Leaves simple, rounded© 2009 John Malpas © Project SOUND
  29. 29. Most manzanitas like  Soils:  Texture: any with very good well-drained soils drainage  pH: 6.1 to 6.5 (mildly acidic) ; may need to amend or use mulch to acidify (pine needles; oak leaves)  Light:  Full sun (coast) to part-shade – even under tall pines  Water:  Winter: adequate/supplement  Summer: occasional water is best – 1-3 times per summer (Zone 1-2) Best away from the coast; likes cooler winters  Fertilizer: none; likes poor soils  Other: use an organic mulch; pine needles are great! © Project SOUND
  30. 30. Why do garden manzanitas need a well-drained soil?  It’s what they are adapted to (root system anatomy)  It keeps you/Mother Nature from over-watering  Winter rain events can ‘drown’ plants in standing water/water-logged soils  Too much summer rain promotes fungal diseases to which manzanitas are susceptible © Project SOUND
  31. 31. Watering Manzanitas: a few pointers  Look to the plant’s natural climate as a starting point:  Lots of rain yearly – some species from very N. coast  Deeper/more frequent wintermorroensis-park-view-manzanita rains – higher elevation chaparral & woodlands  Summer monsoons in August – San Diego county species  Significant summer fog – species from the central and northern CA coast © Project SOUND
  32. 32. Then modify according to your conditions  Temperature  Soil characteristics  Wind, fog and other climatic differences © Project SOUND
  33. 33. Watering manzanitas: some tips  Be sure that ‘expert advice’ is appropriate for your area  Use conventional drip irrigation only to get plants started the first year  Use soaker hoses, soaker-drip or a plain old hose for deep, occasional water of established plants  Only use overhead spray for coastal species that need a fake ‘fog spray’ © Project SOUND
  34. 34. Planting and establishing manzanitas  The best time to plant is in the Fall to early Winter, when soils are moist.  Treat manzanitas as 1 full Water Zone above their final Zone for the first 2 summers. This will often be either Zone 2 or 2-3 (watering every 7-14 days).  Water as the soil starts to dry. Inspect the soil down a few inches to get a true idea of sub-surface moisture. Moisture meters are an inexpensive and effective way to check out the amount of water in the soil.  By 3rd summer decrease to ½ Zone above final Zone.  Ultimately, in about 3-5 years, your manzanitas, can take their final zone - may become independent of your care. © Project SOUND
  35. 35. Treat as a shrub or tree  As a shade tree  As an exotic accent  As a large foundation shrub  On dry slopes  For habitat value © Project SOUND
  36. 36. Arctostaphylos manzanita ‘Byrd Hill’  Naturally occurring variant  A more compact version of A. manzanita (8-10 H x 8 W)  Upright; nice sculpted form.  Very drought tolerant. No summer water (or just 1-2 times per summer – Zone 1-2) once established  Excellent for wildlife. © Project SOUND
  37. 37. Arctostaphylos manzanita ‘Dr. Hurd’  To 15’ tall & wide; fast grower  More garden tolerant: some summer water, richer soil, than Arctostaphylos glauca  Tolerates clay or sandy soils  Tree or shrub form – your choice  Reliable drought-tolerant plant in our area © Project SOUND
  38. 38. Arctostaphylos manzanita x A. densiflora ‘Austin Griffiths’ Manzanita  Hybrid: Arctostaphylos densiflora Sentinel X Arctostaphylos manzanita Dr. Hurd  Tall open shape with bright foliage & pink flowers of A. densiflora  8-10 ft tall; 6-8 ft wide  Sandy soils best; clay ok  Good for habitat hedges/dry hedgerows © Project SOUND
  39. 39. Manzanita hybrids – more all the time!  Are a cross between two species  Can occur in the wilds – and do – but many species never come in contact in the wilds  Hybrids occur readily in the garden setting – manzanita species are ‘promiscuous’  Some hybrids combine the best traits of both parents (‘hybrid cultivars’)  Impact on wild populations – a real potential problem (but not in lower‘Austin Griffiths’ Manzanita elevation western L.A. county) © Project SOUND
  40. 40. Large Manzanitas: are they trees or shrubs?  That’s debatable  Some native shrubby species - mainly those native to California - certainly reach tree size.  However, they generally branch or fork near the ground, thus lacking the single trunk of a tree.Arctostaph​ylos Bird Hill and Lyonothamn​usplanifolia both have open ‘tree-like’ growth  ? ‘multi-trunk small tree’habit that allow them to be ‘pruned up’ intosmall ‘trees’. © Project SOUND
  41. 41. Most Manzanitas look good throughout their lifespan – even without pruning © 2008 Dr. Amadej Trnkoczy blooming-manzanitas.html At four years © Project SOUND
  42. 42. ‘Dr. Hurd’ grows up to be a tree ‘Dr. Hurd’ at 5 years trees © Project SOUND
  43. 43. Pruning to shape – tree-like forms  Judicious shaping is possible.  The trick seems to be not to act too soon - until you can get a feel for the form the plant is taking - or too late, which would leave large pruning scars on the smooth, red bark. ‘Howard McMinn’ © Project SOUND
  44. 44. Start by choosing the right species – and the right plant ‘Sunset’ ‘Howard McMinn’ © Project SOUND
  45. 45. Mother Nature trumps  Most manzanitas are not going to have a single leader (a single dominant trunk that starts at the ground and extends through the tree).  Trying to get that kind of tree will probably not be wise – work with the natural shape © Project SOUND
  46. 46.  Prune manzanitas only inAbove all, do no harm warm, dry weather, to guard against diseases fostered by cold and damp.  Don’t stress the plant by over-pruning:  If its young plant, remove no more than about 25% of its leaf / volume.  Limit pruning of older plants to 10% to 15%. You can always do more next year. © Project SOUND
  47. 47. Prune purposively  If removing a branch or trunk will improve the shape, remove it before it gets too big (< 1.5 inches is good).  Consider pinching small branch tips to redirect growth upward - pinching to an upward facing bud.  Most manzanitas wont form new leaves on a branch if you cut off the part of it that had leaves, so think hard before you cut. © Project SOUND
  48. 48. Can manzanitas be used in hedges & hedgerows?‘Austin Griffiths’ © Project SOUND
  49. 49. Pointleaf Manzanita – Arctostaphylos pungens © Project SOUND
  50. 50. Pointleaf Manzanita – Arctostaphylos pungens  Foothills & mtns of the U.S. Southwest and NW Mexico – 2500-8000 ft.  Locally: San Gabriel & San Bernardino Mtns.  Rocky slopes, ridges, in a_id=1&taxon_id=250092319 chaparral, coniferous forestbin/,3454,3522 © Project SOUND
  51. 51. Pointleaf Manzanita: variable over its range  Size:  3-10 ft tall – often 3-6 ft  3-8 ft wide – often 3-6 ft  Growth form:  Evergreen shrub/small tree  Upright, open habit  Smooth, red-brown peeling bark  In nature may grow in dense thickets  Foliage:  Thick, leathery leaves  Shiny wax coating  Produces volatile chemicals – helps to burn  Roots: shallow, fibrous © Project SOUND
  52. 52. Manzanitas are primarily chaparral plants Environmental  Higher total moisture  Rain & snow  May also have summer rains  Wider temperature extremes  More natural mulch Growth patterns  Evergreen  Longer growth season – spring through summer  May have growth/flowering after summer rains Role of fire: essential for many species © Project SOUND
  53. 53.  Manzanitas contain a high percentage Manzanitas and fire of volatile compounds, which burn like a torch when ignited.  They also carry a large amount of dead wood, making them all the more flammable.  Manzanita can act as a ladder fuel in landscapes, especially when planted adjacent to flammable structures such as homes, decks, fences, and trees. Ladder fuels carry fire from the ground where it can be controlled toTough seed coats and sprouting treetops where it is difficult toroots/ burls are manzanita control.adaptations to life with fire  Flame lengths of manzanita can reach eight times the height of the shrub (i.e. a five foot tall manzanita can generate a 40 foot flame). © Project SOUND
  54. 54. If you need to worry about fire: choices  Plant something other than a manzanita  Plant species from Northern CA or cultivars that can take a little more water; then water them  Choose Bearberries, which are not so flammable but have the ‘manzanita look’ © Project SOUND
  55. 55. Flowers and fruits  Blooms:  Winter to early spring – in our area may be as early as Nov/Dec.  Provide needed winter color, nectar  Flowers:  Typical for the genus: small, white (pink blush) urn-shaped  Fruits:  Small (1/4 inch)  Ripen to showy red in summer; retained through fall  Vegetative reproduction: natural layering © Project SOUND
  56. 56. Growing Manzanita from seed: difdicult  Very difficult to germinate: have both a hard seedcoat and embryo dormancy  In nature, manzanita seeds germinate following fire. Fire provides exposure to heat/smoke and seedbed preparation.  To mimic this natural process, some propagators sow seeds in a flat (wooden flat covered with aluminum foil) and burn a 3-4 inch layer of pine needles on top of the seedbed.  Seeds may take a year to germinate. Once seedlings germinate, they are transplanted to nursery containers. © Project SOUND
  57. 57. Propagating manzanitas by layering is easy  Propagate existing manzanita plants using Mother Nature’s method - the layering technique.  A tender shoot is "pinned" (using a "U" shaped piece of wire) into the soil where it is left to take root for a growing season.  Slightly wound the stem with a sharp, clean knife and give supplemental water to promote root growth. m/AsexualPropagation/AsexaulPropagation.htmlNatural ‘layering’ allows  After roots become established, thesome plants to form a thicket rooted plant can be severed from thegenerated from a single mother plant, grown up in a pot, andplant transplanted in fall following recovery. © Project SOUND
