Q: Questions About Kiwi and Persimmon.

Thursday, November 19th, 2009

A PVFS Customer Email – Staff answer.

Question:

I am very ineterested in buying a couple Persimmon – Fuyu-Jiro (Standard) trees and I have a few questions.  Do these type of trees need pollination? Can they grow well in Southern CA? We live in San Diego County, 2 miles away from the ocean. Also, I would like to learn about Kiwwi. the same questions. Thank you!

Answer:

The Fuyu-Jiro Persimmon does not need a pollinator.  They grow within USDA zones 7-9 as long as you get 200 hours of chill time for them, they should do fine.

Also, the Kiwi doesn’t need a pollinator, both male and female flowers are on the same vine.  I’ve attached your local Master Gardener’s Extension office, they may have better information particular to your area then I have available to me.

Take a Look at the Master Gardeners National Website here.

Hope this helps.

Tomato Trouble!

Tuesday, July 15th, 2008

I planted some heirloom tomato seed varieties that I bought from you this spring in a bed in which I had plant the Soil Builder mix over the winter season. The soil is rich and has good drainage. I have drip irrigation. The bed gets 4-6 hours of direct sunlight every day, and I live in L.A. so it is warm here.

My tomato plants are 5-6 feet tall, with lots of abundant greenery and flowers.  I have only 3 small tomatoes, and the plants have been growing since early May.

Last year I only got a couple of tomatoes too.  The soil is nutrient rich, there is plenty of water, sun and heat.  What’s the problem???

Thanks,
Pamela

Hi Pamela,

There are several factors that might be causing your tomatoes to flower but not set fruit.  Here are some to consider:
-Too much Nitrogen
-Excessive heat; Daytime temperatures over 90, nighttime temperatures in the mid 70’s
-Less than 6 hours of direct sunlight
-Lack of pollinating insects or wind

Seems to me that your plants are on the edge of the sunlight requirement for good fruit production; 8-10 hours are ideal, anything below 6 is questionable.  In case it’s a pollination problem, you might try shaking the flowers to release the pollen.

Hope that helps! Thank you for growing organically!
