My Hardiness Zone ?
The USDA hardiness zones offer a guide to varieties that will grow well in certain climates. Each zone corresponds to the minimum winter temperatures experienced in a given area. Make sure that your hardiness zone lies within the zone compatability range of this variety before ordering.

Size & Spacing

Mature Size

When your plant matures, it will be approximately 5 - 6' tall x 3 - 4' wide.

Recommended Spacing

We recommend spacing these plants 4 - 5' apart to ensure room for growth.


This variety is self pollinating.

In many cases, you may still want to plant pollinating partners to increase the size of your crops, but with self-pollinating varieties doing so is optional. You'll get fruit with only one plant!

Susan W on Mar 28, 2020
I wanted two crops of blueberries so I paired this early variety with a summer variety.
Dana E on Mar 28, 2020
Because it can be grown in pots and only have my balcony available for growing.
Meagan N on Mar 27, 2020
The description says the berries ripen in late-May to early June. We live in an area where invasive insects destroy blueberries, but the caterpillars emerge in July. By selecting these varieties, we hope to harvest the fruit before the arrival of the pests.

Sweetheart Blue berries were out of stock last summer, when I planted my raised blue berry bed. I was dismayed. They sounded so wonderful. I have been buying from Stark Bros for years. I have had great success with most of there trees and plants. I am sure these will be great also. Their customer service is wonderful!

I am replacing a rose bush as I would like a more people and wildlife friendly habitat that does not require spraying like roses do. I love blueberries too!
Laurie G on Jul 28, 2019
We purchased a number of these bushes last year. They are doing great! The berries are large and jucy. Time to increase the quantity of plants!!

It produces 2 crops instead of one!
Michael F on Aug 29, 2017
Kentucky climate can be cold like the north, or steamy like the Deep South. This berry seems equipped to handle both extremes. Plus, website says it can handle some shade, which suits my front yard garden that is tucked at the edge of a large tree.
Aline B on May 30, 2017

What size plant do you send?
Trina M on Apr 1, 2019
BEST ANSWER: Thank you for your question. The age and size information for our blueberries is as follows: 4” pot: 6-12 months old and 4” tall; Small gallon container: 2 years old and 12” tall. Our blueberries will typically take 2-3 years after planting to reach maturity and bear fruit.
what color does the foliage turn to in the fall?
Debbie P on Jun 26, 2016
BEST ANSWER: all the blueberry bush leaves turn red if they are hit with a cold snap as mine are starting red this spring because of cold weather.
how old are the plants being purchased?
Daniel S on Feb 7, 2020
BEST ANSWER: We appreciate you reaching out to us. Our blueberries are approx. 1 year old when shipped.

If you have any further questions please don't hesitate to reach back out to us. Have a great day!
Do these berries have thorns?
Pnuts on Jul 22, 2018
BEST ANSWER: No. You might be thinking of blackberries or raspberries.
Is this plant sprayed with any chemicals or pesticides?
Tamara C on Jul 30, 2020
BEST ANSWER: I have not had to spray my Sweetheart blueberry plant with anything. It bears a very tasty plentiful crop each year, is compact and I am very satisfied with it.
I live in zone 6 and we have plenty of rain so I don’t water my berries. I use an acidifying fertilizer twice during the spring and summer, and that’s it.
Will the blueberry plants overwinter in containers in a zone 4, or would I have to move them into a sheltered area?
HillaryN on Apr 29, 2017
BEST ANSWER: Typically, containerized roots will survive temps above 20 F, in my experience, but they must be very moist. If they dry in the container, they won't survive 30 degrees. If expected temps get lower than 20, then you should consider an insulation blanket, or a protected area, like a shed. Try to find a place that the temperature fluctuation is minimal.
Is Aug 6- Sep 8th really the best time for planting in my area (Zone 8)? It will be in the 90s every day... But you site seems to be calculating that is the best time? I just want to double check...
Bee R on Aug 2, 2020

Are all of the blueberries that you have can they be shipped to California. I have been looking at keep coming across that the blueberry plant cannot be shipped to California?
MAY O on Jun 25, 2020
BEST ANSWER: We appreciate you reaching out to us. I do not see any restrictions at this time for California, however they update those restrictions daily so this could change at any time.

Can you grow Sweetheart blueberries in a container?
Jennifer M on Apr 4, 2020
BEST ANSWER: Jennifer: yes you can grow blueberries in a container. If it is to suficient size,
At least 12 inches deep and at least 3ft. Diameter. Blue berries need moist but well drained soil, with a ph of around five. I have heavy clay soil that doesn't drain well, so I plant them in used farm tires above ground so that they drain well. Be sure to use a mix of peat soil and other amendments that drain well and provide a lower ph. Mulch with pine needles if you can get them.Use a fertilizer for acid loving plants. I was disappointed with the quality of the plants I revived from starks. They were very small and diseased. Would not order from them again. Hope you have better luck. If not try to go to a local nursery where you can observe the plants first hand, and select heathy plants.

Can this survive in zone 9a?
Kim M on May 12, 2019
BEST ANSWER: This blueberry is only zoned to 8 - the plant would suffer heat stress and probably not produce very well because it won't have enough chill hours. You'd be better off with Sunshine, Misty or Jubilee.
How disease and insect resistance are Sweet Heart blueberries? I live in zone 7B. Will that make disease and insects a bigger problem?
John R on Feb 18, 2018
BEST ANSWER: Sweetheart blueberries are quite disease-resistant to a number of conditions, provided that you keep the soil pH between 4.5 and 5.0. Living in Zone 7B should not present additional problems. If you have a particularly hot, dry summer, check the moisture level often because blueberries have shallow roots and they will dry out faster.

Great plants
I planted 3 sweetheart blueberries in the spring last year when it was raining. Shortly after planting we had one of the worst droughts and the most 90+ temp days. All 3 made it and have doubled in size with the wet spring this year. One even has fruit on it.

Sweetheart Blueberry
This was a gift to my brother and then I got it back because he was unable to care for the plant. I planted it last fall. This spring it was growing well and even had blossoms. It survived a brutal frost and proceeded to develop berries. They were few but had a nice flavor. I would order more for my berry patch.

Sweetheart Blueberries
They are not thriving in my growing conditions. The Sweethearts are just a few of the 17 plants that I am growing. The others are thriving and producing, the Sweethearts have trouble producing leaves. Am considering giving up on them and using the valuable space that they take up with another variety.

It took 5 years, but worth the wait
I had just about decided that blueberries just wouldn't grow on my land. Then, for reasons I don't know, this year it was covered in large, sweet berries. Hopefully, it wasn't a one-time fluke. I have another Sweetheart that's just beginning to grow like the first one. Hopefully, I'll have 2 bushes full of berries next year.

Healthy plants
Got them in 2015. They were healthy and I transplanted them into the ground. Our soil is acidic so they like it. No blueberries yet but they are growing and look very healthy. I will mulch them with oak leaves before winter.

Need more time to evaluate
5 of the 7 plants I bought are leaved out. No berries yet. 1 is struggling and the other is small still but slowly growing. This spring no leaves came on the plants until the first week of May. All my other 100 or so blueberry bush varieties had berries already. I'm in zone 8a. I will be disappointed if I don't get a double crop. I think as they mature they will begin the double crop characteristic. I need more time to watch them to give a more accurate review. A 3 for now, hoping I can change that to a 5 soon.
