Think it won't hurt to help the plants along. Other reviewers had good comments about helping plants to grow and fruit.

I bought the strawberry food which works wonderful in my garden. So now I've decided I need this one as well.
Kimberly V on Apr 29, 2016
My Red raspberries flourished with this last year and my black raspberry plants are doing well; so I intend to continue using this great product.
Kimberly B on Apr 12, 2016
We used this last year for the first time and had a bumper crop of blackberries, more than the plants have ever produced.
RITA R on Mar 23, 2016
I always forget to fertilize and thought that this would be handy if I bought it now.
GUY S on Mar 16, 2016
Don't remember using this before but because of the blackberry food, I will try this to see if it works as well on my raspberries.

How often during the season do you apply this product? Thanks
greasewood on Feb 23, 2017
BEST ANSWER: I applied this product only at the beginning of the spring . . .
What is best way to prevent weeds in raspberry beds?
Johnnie Vee on Feb 27, 2017
BEST ANSWER: We put a fluffy, non-compacted, 4-6" layer of straw (not hay!) across the raspberry bed. A few weeds came up but they had no solid ground to root into so they were simple to pull when they emerged.
Can this fertilizer be used on established beds? My plants are not producing...very little raspberries. This is an older bed. I'm planning to plant some Stark Latham raspberries in the spring, too. Thanks for your help!
Kathy on Nov 10, 2016
BEST ANSWER: Raspberries often benefit from heavy cultivation and pruning. Starks raspberry food has been doing very well for me. I also add a little compost each season.
How much is too much? I mixed up a gallon and poured it along my one row (`~20 ft) of 6 raspberry plants. It didn't really saturate around the plants, but I don't want to overdo it!
Lindsey on Apr 11, 2017
BEST ANSWER: You're good! That is exactly the right amount. The next rainfall or watering will distribute the food down further into the soil. One gallon of solutions treats a 20' row, so you are spot on.

200% growth
I used this product, applied it according to instructions. Nothing has ever worked as good. My plants tripled in size and I have harvested more berries this year than the last 4 years combined. Plants not only showed good growth but new shoots are sprouting everywhere.

Must have helped
Must have helped as my Jersey Raspberry plants produced tons of berries. This was my first time planting and I did nothing but feed the plants. Oh yeah....I also ate a ton of berries as a result!

Big Spring Kick....
I just planted new bare root raspberry plants. I gave them Stark's Raspberry Plant Food at planting. All 6 different cultivars, a total of 24 plants have taken off.
I will use this product in the future.

Hold on Tight!
This fertilizer really kicks into high gear about 2 weeks after application. My Raspberries are giving me about a quart a day right now, some canes are as tall as I am.

this product is great
I used the raspberry food early this Spring on my two rows of raspberries (about 80 feet long). We had the most incredible harvest of raspberries this year! We made so much jam, juice, pie, vinegar, and froze a ton of berries. We almost couldn't use all of the harvest - there was so many berries! I will use this product every year.

Great Food for Red and Black Raspberries
I used this Raspberry Food on my year old Raspberry plants. The plants are strong and healthy looking. The Heritage Raspberries should be ripening soon and there are so many, can't wait to harvest them. The black raspberry plants are larger than expected for one year old transplants. Will continue to buy this Raspberry Food for my raspberry plants, they apparently love it! Thank you, Stark Bros.
