Q.hardy kiwi
Have supposedly 1 male and two females. Plant more than 4 yrs old. I have fertilized slightly with 10-10-10 and pruned sparingly. Last year I saw only one blossom. Otherwise has never bloomed. Please advise. Thanks so much.
The plants often take several years to mature, fruiting can take 5 to 9 years.
Your fertilizer choice is correct, so you just need more time!
Here are some links with care information.
