It's doing really well. I will be transferring it to a bigger pot probably by the weekend. I wish I had a little more instructions on how to care for this variety, and what to do in the fall.

Semi Dwarf Harko Nectarine Tree on Citation (Prunus persica var. nucipersica ‘Harko’) is a cold-hardy nectarine variety valued for its smooth, bright red-blushed skin and exceptionally sweet, juicy yellow flesh. With a richly flavored freestone interior, Harko is excellent for fresh eating right off the tree but also perfect for canning, baking, or making preserves. This Canadian-bred variety is noted for its late bloom, which helps avoid frost damage, and its natural resistance to bacterial spot. Grafted onto Citation rootstock, it offers moderate vigor, adaptability to various soils, and reliable harvests for backyard growers and home orchards.
Growing Semi Dwarf Harko Nectarine Tree on Citation
Light: Requires full sun to achieve the best sweetness, blush, and fruit size.
Soil: Prefers fertile, well-draining soil; amend with compost or organic matter to support healthy growth.
Water: Water deeply and regularly during the growing and fruiting season. Reduce watering after harvest to prevent excessive vigor.
Fertilizer: Feed with a balanced orchard fertilizer in early spring and midsummer to encourage steady growth and productivity.
Pollination: Self-fertile; sets fruit without the need for another variety, though multiple stone fruits nearby can enhance yields.
Maintenance: Prune in late winter to maintain an open canopy, improve sunlight penetration, and encourage new fruiting wood. Thin fruit in early summer for larger fruit and better flavor.
Hardiness: Best in USDA zones 5–9. Harko ripens in mid- to late summer, producing consistent, high-quality crops even in cooler climates.
Shipping Info
This tree is grafted onto Citation rootstock, selected for its controlled vigor, adaptability to different soils, and ability to yield fruit of excellent size and flavor. Shipped bare-root in a dormancy state, with proper care and planting instructions included.

Plants arrived fine.. got them planted. Now i will let you know next spring. If they survive and grow back.. So far, i am ok with them
Erigeron Karvinskianus Fleabane ‘Santa Barbara/Mexican Daisy'
Just waiting for when they get big and tall and start producing bananas.
Plant arrived quickly and came in good shape!
Package came delivered just like it said it would I pulled it out it looked good. I put it in some water for about a half hour and put it in my 30 gallon tub and I got three things to go with it.
Banana tree came nice and healthy and ready to go!

Haven’t transplanted yet, but it’s a beautiful plant. We are gifting it to a friend that moved…Friendship Plant is very appropriate!
I love it
Truly tiny is still tiny but healthy!
It seems to be doing well but could have been packed better.
Blossom Dale did a wonderful job with packaging and Sedum Autumn Joy plants arrived in great condition and are thriving. So far so good.
The milkweed is not doing well...
Very healthy cutting. Followed the instructions and let it get acclimated to its new surroundings for a couple of weeks before repotting. Would not hesitate to purchase from this business again 😃
Plants arrived in great condition. This plant has only been in the ground about 10 days and is growing a lot. The plant cage is 12” tall so it’s doing well. I put guards around my new plants for a little while because I have bunnies who love tender young leaves.
Got this for my wife’s birthday. Plan to pot it soon.
I got 2 mystery plants (one indoor and one outdoor). The indoor was a pilea and the outdoor plant was a white blackberry. White blackberry was dramatic, but it’s making a comeback and the pilea is doing great!
Came in well packed and the plant was alive and healthy!
Even though the newest leaf was broken off it seems to be doing well
My little banana arrived happy and healthy!
The plant arrived well packaged with instructions on how to get started. It had been doing really well and has been growing like a weed!
It is just putting roots down now.
Received in great condition, transplanted just before heavy rain and its thriving
Just a little shock put her in a fabric pot on the back porch full sun should be happy thank you for the lovely plant
Fair price good looking plant can’t wait for it to get bigger!
Need to upgrade your packaging. I would suggest taping the plant in place in the cardboard tube on the count that it slid and smashed itself. Luckily, it's a strong plant and should recover. Hoping.for the best.
So Beautiful. Packaged well . Love my little guy.
It’s so cool I love it!!!
She is doing well even after a rough delivery. She is thriving and putting on new growth. Thank you.
The plant arrived after a few delivery reroutes. It came with three leaves two so far are healthy one was dying and has since died. The two remaining leaves appear to be doing well.
After overcoming the initial travel stress. The plants are doing well.
The follow up plants were very good
Customer service here is second to none! Very very happy and already made another purchase. But anyway, I ordered 1 and they sent me 2 beautiful babies! I'm so excited to watch them grow!
This little guy came in perfect. Despite the cat knocking it over and being placed in the soup cup for safer keeping, it’s thriving and happy. Once it’s bigger then it will make its way outdoors.
I like it very much and looking forward to eating some cherries
This is my first year of ordering live plants on line. I live in an apt, but have a nice size patio to do container planting. I'm waking up my green thumb and loving it.
Got a great little house plant for $9.99!!!
I am very happy for all the Butterworth I got extra like usual which was nice I put them all in pots for now I'll do my project later after they get growing thank you
Plant came packaged perfectly. Fast shipping. Can’t wait to see it grow!
