Brambles: Growing Blackberries and Raspberries



Nothing is better than a cane ripened blackberry or raspberry.  They are incredibly sweet!  Store bought fruit is picked before it is ripe because is it firmer and handles shipping better. It is sour because it was not allowed to ripen on the cane.  Store bought berries are also expensive. It is definitely worth the investment and effort to grow your own berries.  They are highly nutritious, easy to grow, delicious, and have many options for preserving.



Blackberries and raspberries are brambles. They are made up of a small group of fruit called aggregates that adhere to a receptacle.  One of the differences between blackberries and raspberries is that raspberries pick free of the receptacle and blackberries retain the receptacle when picked.

General Guidelines for Brambles

Brambles like full sun and protection from wind.  They need soil with good drainage and lots of organic matter.  Avoid clay and areas where they will have "wet feet" or standing water.

Both raspberries and blackberries will spread and propagate.  Raspberries send up new canes and are vigorous and invasive.  I recommend planting in 2 foot wide boxes or within a cement area.  A two foot wide planting area allows you to pick berries easily from both sides. 

 Blackberries while not quit as troublesome to contain as raspberries also send up new canes and will tip propagate also.  Both will also need some kind of trellis.  With erect blackberries, you can get by without a trellis but it is nice to have something to tie the canes to so the berries do not touch the ground.


I also highly recommend purchasing certified virus free plants to start your bramble patch.  Although tempting to get starts from your neighbor, you may be bringing diseased plants into your garden.  I also like bare root starts. Bare roots come to you dormant and with no soil around the roots. Obtain these in early spring. Bare root starts seem to be healthier and more productive than container plants and you also have more options in varieties.  I have had good success with these nurseries:  Raintree, Miller, and Jung.



Establishing a Bramble Patch

Preparing the Site


  • In choosing your site,  do not plant where strawberries, tomatoes, peppers or potatoes have been planted within the last 5 years.
  • Plant in rows no wide than 3 feet.  This allows for easy harvesting, pruning, and watering.
  • Place raspberries 2-3 feet apart.
  • Place blackberries 4-5 feet apart
  • Before planting incorporate organic compost into the soil.  Also add some complete dry organic fertilizer
  • Build your trellis

Planting


  • When you receive the raspberry bare roots stock, open it up and moisten it.  
  • If you are not ready to plant you must keep the plants cool and moist
  • When you are ready to plant place the roots in a bucket of water and avoid exposing the roots to direct sunlight
  • Plant the crown just below the soil level
  • Bare roots have one short cane called the handle.  This will not leaf out.  New canes come up around the handle.
  • Keep the soil evenly moist and mulch around your berries.

Maintenance of Brambles


  • Keep rows or boxes weeded
  • Prune in early spring
  • After pruning and while dormant, spray with a dormant spray to smoother pest eggs.
  • Apply dry organic fertilizer in early spring
  • Add a layer or 1-2" of organic matter around canes
  • When buds break and at flowering ferilize with fish emulsion and sea kelp.  Fish emulsion is applied in a watering can around roots and kelp is used as a foliar spray



Blackberries

Blackberries are a member of the rose family along with raspberries, strawberries, apples, and peaches.  A very delicious plant family.

Blackberry stems are called canes.  The roots are perennial meaning they live for years.  The canes, however, are biennial meaning they live only two years.  The roots send up new canes every year.  Why is this important to know?  In order to have productive harvests and large berries you need to prune blackberries properly.  To do this you need to understand what is going on with the canes.

The first year canes are called primocanes.  They do not bear fruit the first year.  The job is simply to grow vegetatively which they do quickly and aggressively.  The second year canes are called floracanes.  They are the canes that will flower and bear fruit.  During the fall and winter they will die having completed the cycle, but remember the root also send up new primocanes every year which will provide you with fruit the following year.



 Sound confusing?  Just remember the canes live two years.  They grow the first and bear fruit the second.  If left unpruned they will not be as productive.  We prune to encourage fruiting and tame the growth of the canes.  They can grow 15ft in the first year, but that growth does not encourage more berry production.





 

Sounds simple until you go outside and look at the mass of canes.  So to review the process.


  • Cut all dead canes to the ground
  • Cut all canes to a height of 5-6 feet and tie to a trellis this stimulates lateral can growth
  • The lateral canes come off the main cane they must be pruned to 18-24 inches or 12 buds
  • All cuts should be made to just above an existing bud.
  • Cut out all weak and diseased canes.
  • Clean out leaf litter from around canes.
  • Sprinkle dry fertilizer around canes
  • Spread a layer of mulch around. 



Maintaining Blackberries

Newly Planted
  • When canes reach 5-6 feet tip off canes.
  • This is usually done in July
  • This encourages lateral shoots which are where fruit will be borne next year.
  • New primo canes will come ups from crown of the plant
 In the Early Spring:
  • Prune to the ground all canes the bore fruit
  • Burn or take the pruned canes to the dump
  • Thine remaining primocanes to about 7 -12 per plant
  • Do not prune out flora canes
  • Prune lateral branches on main canes to 12 buds
  • Tie the pruned canes to your trellis
All Blackberries:

- Clean up leaf litter around plants after pruning
- Sprinkle a complete dry organic fertilizer around base of canes.
- Add 1-2" of compost around base of canes.
- Spray with a dormant oil when nighttime temperature is in 40's.

Types of Blackberries

Erect varieties do not require trellising.  They are very cold hardy.  Good varieties are Arapaho, Apache, and Navajo.  I like these varieties best for my planting zone.  They are easy to maintain and very productive.

Semi-Erect varieties need a trellis and are less cold hardy.  Suggested varieties include Black Satin, Triple Crown and Chester.  I do like Triple Crown I have not tried the others

Trailing varieties are tender and require winter protection.


Harvesting Blackberries

  • The color of the berry will develop before the flavor.  Resist picking early.  It's worth the wait.
  • Immature fruit will be shiny black
  • Mature, sweet fruit will be a dull black
  • The mature fruit separates easily from the plant
  • Pick mature for fresh eating and slightly immature for canning
  • Berries can easily be individually frozen and then placed in ziploc bags.

Raspberries

Raspberries are very cold hardy and aggressive plants.  The roots spread out laterally 3-4 feet in all directions.  Buds are randomly produced along the root from fall the spring.  The canes from these buds will easily reach 6 foot in length.  

Raspberries fruit from the tip and on down the cane.  The last two or three buds below the ground remain vegetative and will produce the primocane the following season

Raspberries are one plant you do not want to neglect.  As I said before they are best planted in raised beds no wider that 2 feet and must be pruned to control growth and keep up berry production.



Types of Raspberries

Summer Bearing
Summer Bearing produce one large crop in late summer or early fall.  They can be further categorized as early bearing, mid season, or late bearing.  The harvest period will last about 4 weeks. Popular varieties include, Canby, Latham, Taylor and Kilearney.  I had Taylor and Kilearney but the everbearing Caroline are by far my favorite.  The taste of summer bearing is very good but production is low and the berries are not as big.

Pruning Summer Bearers:
- Prune in early spring before bud break
- Cut all dead canes that bore fruit last year out to the ground
- Thin out spindly weak canes and those outside the growing area
- Thin out canes to 10-12 per square foot leaving healthiest canes
- Top canes off at 5' to induce lateral shoots where fruit will be produced



Everbearing raspberries generally have 2 harvests per season;  one in mid-late summer and one in the fall. Varieties I like include Polka, Meeker, Caroline, and Anne.  I highly recommend Caroline, Polka, and Meeker.  They are very productive, vigorous, and produce large berries.  The primocanes of ever bearers will bear fruit on the tip the first year, and the 2nd year produce fruit below the tip. 

Pruning Everbearer:

- Prune in early spring before bud break
- On primocanes that bore on the tip, prune just below the tip that   bore.  Prune 1/4 inch above a healthy bud
- Prune out all dead canes.
- Thin out spindly weak canes and those outside the growing area
- Thin out canes to 10-12 per square foot leaving healthiest canes
- Top canes off at 5' to induce lateral shoots where fruit will be produced

All Types of Raspberries:
- Clean up leaf litter around plants after pruning
- Sprinkle a complete dry organic fertilizer around base of canes.
- Add 1-2" of compost around base of canes.
- Spray with a dormant oil when nighttime temperature is in 40's.

Preventing Curly Top in Tomatoes



Tomatoes are the one crop I look forward to the most in my garden.  I know I'm not alone in loving homegrown tomatoes.  Tragically tomatoes are disease prone and at the mercy of many pests. Curly top is a disease transmitted by and insects so you are dealing with both pest and disease.
  
To deal with curly top you need to understand how the disease is transmitted to the tomato plant.  As the grasses in surround areas dry up leafhoppers, who are the lovely little vector for curly top virus, leave the fields and come to your much greener garden to feed.  They feed on the juices of a plant and can infect your tomatoes with curly top. So leafhoppers vector the virus we call curly top.

Curly top is a virus that spreads throughout the whole plant and unfortunately there is no cure.  You must ruthlessly remove the plant.  Leaving it in the garden will allow other insects to feed on the infected plant and spread the virus to other plants.


Leaves of infected plants twist and curl upwards.  They become stiff and leathery.  Sadly they eventually turn turn yellow, then brown and die.  Curly top can also effect melons, spinach, beets, and beans. 


To help prevent curly top remove weeds around your garden and control pests. 


Since most of my tomatoes are heirlooms that I start from seeds, it is very discouraging to have to tear out a plant.  I do usually start 2 or 3 of every variety.  I plant one or two in the garden depending on the variety and keep one the potting shed incase I lose one to curly top.  Generally I only lose 2 or 3 plants out the the 30+ tomatoes I plant to curly top.



Caging and Covering Tomatoes

After tomatoes are in the ground, prepare a cage to cover the tomato.  I use a light to medium weight floating row cover cloth to make shades for the tomatoes. Floating row covers allow a % of light to penetrate and are used to protect from insect damage and frost damage. Cut the row cover cloth a couple inches bigger than your cage.  Use clothes pins to secure.  Start with the shade cloth as close to the tomato plant as possible.  Move the cloth up as the plants grow.  Remove completely when the tomato is growing out of the cage.


I do use a preventative spray to discourage leaf hoppers and various diseases. The sprays are organic and safe for beneficial insects if used properly.  If you don't want to spray you can cover your tomatoes with a row cover.  Some studies have shown that putting a shade cloth over the tomatoes makes it more difficult for the leafhoppers to find them.


Disease preventing strategies


Today I weeded around the tomatoes gave each plant a drink of fish emulsion, and spread a layer of mulch around each plant. Prune off any lower leaves that don't look good. Put them in a plastic bag in the trash just in case they have a fungal or bacterial disease. I did my first spray this morning which will ward off leafhoppers, tomato horn worms, and prevent some diseases if done relgularly.


In a 1 gallon sprayer I add the following depending on what problem you are having.  For example if you don't have horn worms don't add Spinosad if blight is not a problem don't add Serenade.  The neem and kaolin clay are deterrents for the leaf hopper that spreads the curly top virus:


  •  1/2 cups of Kaolin Clay  this is a deterrent for any chewing or sucking insect. Add this first with half the water and shake. Then add the remainder of the water and the following.  If you do not have all these that's fine.  Use what you have.


  •   2 Tbsp of Neem/ gallon-  Neem is an insecticide and fungicide.  It is systemic and taken up by the plant an spread throughout the plant tissues.  When insects feed on the plant, they are inhibited from molting and laying eggs.  It is also a repellent.  It kills a wide range of insects and is not harmful to beneficial insects because they must ingest it in order to be affected.


  •   4 Tbsp of Spinosad-  Spinosad is bacteria that is very effective on caterpillars, thrips, aphids and other pests. Good for tomato hornworms so only use if you have hornworms


  •  4 Tbsp of Serenade- Serenade is a bacterium,, bacillus subtilis, that prevents fungal diseases.  It must be used prior to the pathogen being present. Fungus diseases include mildews, blights, wilts, and anthracnose. Only use if blight is a problem


     2 Tbsp of Kelp  a great foliar spray

Mix all this and you are ready.  I also use this on potatoes, cucumbers, squash, pumpkins, melons and corn. 


These are the organic options for disease and pest control. Please do not buy the Pyrethrin brand shown it has an additive that makes it not approved for organic gardens.  Garden's alive and Peaceful Valley have one that is only Pyrethrin.

Strawberry Rhubarb Jam



What a great combination:  strawberries and rhubarb!  This is definitely a family favorite. You can harvest rhubarb in early spring and then again in the fall.  Never harvest more than 1/3 of the plant.  Everbearing strawberries will still be producing berries in the fall so it a great time to get this delicious jam on your pantry shelves.


Crimson Red Rhubarb


Recipes for this jam are easy to find.  I use the one in the Ball Blue Book. This is a must have book for anyone serious about preserving food.  I recommend this book for everyone and suggest you actually read about the principles and equipment.  Sometimes we think we know it all when in fact half of what we know just isn't so.  So read the book. 

Our favorite thing to do with Strawberry Rhubarb Jam is to put it on a omelet. 


Ozark and Tristar Strawberries



Directions for Strawberry Rhubarb Jam

Strawberries for this can be fresh or frozen and thawed.  Drain any juice if using frozen. Put strawberries in pot and smash with a potato masher to crush them. Add rhubarb, pectin, and lemon juice.  Have your sugar  pre-measured in a bowl.  Bring the fruit to a boil.  Add sugar and return to a boil.  Boil 1 minute. Skim the foam off.  It helps to let it sit a few minutes then skim. Add to jars.  Wipe rims. and process in a water bath canner for 10 minutes.  I'm at 5000 ft so I always add 10 minutes to the processing time. Be sure to process for the appropriate time for you altitude  Check seals before storing.  Rings can be removed.




Strawberry Rhubarb Jam

Yields about 6 half pints.
2 cups crushed strawberries
2 cups chopped rhubarb
1 package powdered pectin
1/4 c lemon juice
5 1/2 c sugar
