November Work Party – Potting Up for the Spring Plant Sale

By on November 1st, 2012

Saturday, November 3rd, 10am-2pm

We had a successful planting party last Saturday. Some of us cleaned the daffodils while others weeded the Equisetum out of the bed. Then we planted over a thousand daffodil bulbs. Won’t it look lovely in the spring!

Now we’re planning a potting up party at Kandy’s. We have bulbs to pot up from our bulb sale, and clumps of plants to pot up, both for our spring plant sale in April. We also need to prep the nursery area for winter. If it rains we can do the potting up in Kandy’s garage and greenhouse and keep out of the rain, and leave the prep of the nursery for a dry day.

We’ll be at Kandy’s 14555 Stone Ave N, Shoreline. Park along the street. Bring clothes for the weather, pruning shears, gloves, etc. Kandy’s is one block east of Aurora on 145th. Take the NE 145th exit from I-5 and head west towards Aurora. Just before you get there, turn right onto Stone Ave N. Kandy’s house is at the bottom of the hill. Park on the street.

General Bulb Planting Notes

By on October 28th, 2012

General Notes

General

  • Bloom seasons are always approximate due to weather variations. E = Early EM = Early to Mid-season, M = Mid-season, ML = Mid to Late, L = Late
  • Almost all Tulips and Narcissus are packaged 5 bulbs per bag. See label for all other bulbs, for bulb-count per bag.
  • Always remove spent flowers from Narcissus and Tulips, but not the whole stem as stems also feed next year’s bulbs.
  • Feed all bulbs with a bulb food or vegetable food, or a balance of NPK like 5/10/10 when tulips are up about 2-3”. This will feed next year’s bulbs well.
  • Most bulbs should be planted as deep as 3X the diameter of the bulb, although it can be shallower if mulched after planting.
  • Plant small bulbs first, then Narcissus and Tulips last (they root the fastest). It is best to plant no later than November 1st.
  • If bulbs are rooted well, they will not be damaged by freezing.

    • Narcissus

  • The last Narcissus to bloom is Pipit.
  • Narcissus class Jonquilla tend to get about 5” taller than labeled, in the PNW.
  • Narcissus colors are listed perianth / cup.

    • Tulip

  • The last Tulips to bloom are the Lily-flowered and Viridiflora.
  • Tulips form a new bulb or bulbs each year and need full sun and heavy feeding to grow a bulb up to flowering size. Usually they form 2 or 3 undersize bulbs in pots or in the garden. Most who get tulips to Perennialize have a dry summer garden in full sun. The species will perennialize easily, but must have these conditions.

    • Crocus

  • Dutch crocus are the large flowered crocus. Do not mix yellow with the other colors as they are a bit weedier when planted en-masse.
  • To plant crocus, plant them about 2-3” deep, mulch, water in well, and cover with mesh or boards for about 3 weeks. The squirrels cannot smell them as easily if they have begun to root.

SEPTEMBER – Zsofia Pasztor – Low Impact Development

By on September 10th, 2012

Zsofia Pasztor

Using hardy and native plants in low impact development

Monday, September 17th, 7pm – 9pm

NHS Hall Section A, Center for Urban Horticulture, 3501 NE 41st St. Seattle, WA 98105 Map
Low Impact Development

Low Impact Development – Zsofia Pasztor

Low Impact Development is the new buzz. LID involves soils and plants most of the time since these are the two foundational players in the hydrological function of a site. Rain gardens, green roofs, living walls, bioberms, restored or preserved natural areas are all LID solutions. Plants are the best allies, they look great, add value to the property, provide habitat to wildlife and manage water proficiently since this is what they ‘just do’ by their nature.
