Planting Information for Asparagus
Spacing
- 12" – 14" between plants unless otherwise specified
- 6" – 8" between plants is recommended for Purple Passion
- Furrows should be 8" – 10" deep for most soils
- Furrows of 8" is recommended for heavier clay–like soils
Irrigation
- Plants need a well–drained site
- Lighter soils may require more frequent watering
- Important to maintain moisture during establishment year
Fertilization
- Before planting add 5lbs of 10–10–10 per 100 sq ft
- In establishment year dress in August with 1 lb 10–10–10 per 100 sq ft and work into top 2" of soil
- In following years use 2lbs 10–10–10 per 100 sq ft in early spring and again following harvest
- Lime, bone meal, and super phosphate help maintain proper soil levels
- pH: 7.0–7.2 This is very important
Weed Control
- Ferns will die back naturally in the fall
- Mulching dried ferns with mower in fall will reduce weed pressure
- Contact a local extension for chemical recommendations
Planting Information for Blackberries
Spacing
- Blackberries should be planted 3’–4’ apart
- Recommend 8’–12’ between rows depending on machinery
Irrigation
- Soak in water using Agri-gel™ for 1–2 hrs before planting (except TC plugs)
- Water thoroughly after planting
- 1"–2" rainfall or equivalent per week
Fertilization
- Before planting add ½ – ¾ lb of 10–10–10 per 100 sq ft
- Commercial growers should use 500 lbs per acre
- An additional 1lb of 10–10–10 per 100 sq ft can be applied in July or August and in early spring in following years
- pH: 6.5–6.8
Weed Control
- Regular cultivation is necessary during growing season
- Roots are shallow – don’t cultivate more than an inch deep
- Mulching during establishments can help control weeds
- Contact a local extension for chemical recommendations
Trellis
- We suggest plants are supported by a 5–wire trellis or put into a staked–hill system.
Planting Information for Blueberries
Spacing
- 4’–5’ between plants
- 8’–12’ between rows
- Be careful not to plant too deeply
Irrigation
- Keep soil moist throughout the establishment period
pH Requirements
- For best results, amend pH levels before planting, however, plants can be successfully established without prior pH adjustments if you follow our instructions
- Measure/maintain pH levels regularly for best success
- Adding sulfur may be necessary to adjust pH: 4.5–4.8 this is very important
Fertilization
- Wait 4–6 weeks after planting before fertilizing to avoid burning roots
- Year 1– 1oz ammonium sulfate in a circular band around each plant
- Following years – 2oz per plant at bloom time and again 1 month later
- Don't fertilize after July
- Avoid fertilizers containing potassium chloride
Weed Control
- Mulch with 3"–4" wood chips
- Avoid treated or colored bark mulch
- Regular manual weeding is necessary
Special Considerations
- For best production at least 2 blueberry varieties should be used for cross-pollination
Planting Information for Currants
Spacing
- 3’ – 4’ within row unless otherwise noted
- Rows should be at least 6’ apart
- Choose a sunny location, but avoid southern exposure
Irrigation
- Planting on a slope facilitates drainage
- 1" – 2" rainfall or equivalent per week
- Maintain adequate moisture especially following planting
- Gooseberry fruit will sunburn more easily if soil is too dry
Fertilization
- None is required during the planting year
- In following years, 5oz. of 10–10–10 per plant in spring or split with half in spring half in summer
- pH: 6.0 – 6.5
Weed Control
- Cultivation by scuffle hoe or manual weeding is needed
- Mulch will assist with weed control
- Straw, sawdust or woodchips can be applied at 2" – 4"
- Contact a local extension before using chemicals
Pruning
- Black currants have different pruning needs from red currants and gooseberries. See pruning guides for specific techniques.
Special Considerations
- Black currants produce better with 2 or more varieties
Planting Information for Elderberries
Spacing
- 3’ – 6’ between plants
- 10’ – 12’ between rows
- Plant at same depth as grown in the nursery, all roots should be well covered.
Irrigation
- Keep soil moist throughout the establishment period
- Between flowering and through harvest, 1 inch water via rain or by hand is recommended
Fertilization
- No fertilizer in the planting year
- In succeeding springs, mix 1 cup 10–10–10 per plant in a circle around the plant
- Does well with various animal manures – apply manure or compost after plants begin to grow
- pH: 6.0 – 6.8
Weed Control
- Thorough, manual weeding is necessary, but do not cultivate deeply. Roots are fibrous and shallow. Generally once established a thick planting will suppress weeds on its own.
- Compost or straw mulch will help
Special Considerations
- Elderberry plants are generally free of pests
- Birds absolutely love elderberry and an un-protected bush can be stripped clean as soon as berries turn color! Netting seems to work best.
- Plants will fruit in second year, and those canes should be removed late that fall, and every fall thereafter, cut out the fruiting canes. The growth habit of these new varieties makes it easy to prune and maintain a nice bush.
Planting Information for Gooseberries
Spacing
- 3’ – 4’ between plants
- Rows should be at least 6’ apart
- Choose a sunny location, but avoid southern exposure
Irrigation
