Is a thundercloud tree and a flowering plum tree a hardwood or a softwood?

They are both propagated best from softwood.

Ridding Soil of Root Maggots

Our home is on what used to be a plum orchard. It was suggested that we may have root maggots. We have lived here for 21 years. What can we do to get rid of them before planting another tree in the front yard? We do have two fruitless mulberries in the back that are doing just fine.

Plum Tree That Don’t Produce Fruit

What kind of fertilizer would help this tree to produce fruit? The tree looks healthy.

ANSWERS

Plum trees take about 3-4 years to reach fruiting maturity. If your plum is this old and still not producing fruit, there are several things that could be causing this.

First, it may not be getting enough light to flower.

Second, it might have too much nitrogen or too little phosphorous. This is common for fruit trees that are planted near lawns that get regular fertilizing. lawn fertilizer is high in nitrogen and low in phosphorous. Adding bone meal can help, but it is advisable to get your soil tested at your local extension service and see exactly what and how severe the deficiencies are.

Third, you may be growing a variety that needs more chilling than your area can provide. Many stone fruits need a certain number of hours of cool weather in order to fruit well. The number of hours varies by variety and you would need to look up your variety to see how many hours of chilling it needs.

If you are seeing flowers but no fruit, this can mean that you have a pollination problem or that the blossoms are being damaged by late frosts and therefore never become fruit.

What Should I Do About My Plums That Fall Off Prematurely?

Each year, my plums bloom and produce lots of early plums. Then when the plums are about a grape size, they begin to fall off. Maybe 10% will make to maturity . . .the rest fall off on the ground.

This happens due to poor pollination. These articles have some suggestions for improving attracting pollinators to your yard, which will result in more flowers pollinated and less fruit being aborted by the tree.

Espalier Fruit Trees

I’d like to plant three espaliered fruit trees along my fence. I was thinking of plum, pear, apple, and/or peach. Will these survive/thrive in the Reno/Sparks area of NV (USA), or should I consider something else? Or abandon the idea completely?

ANSWERS

As long as you can get them enough water, they should be fine.

Fruit Tree Winter Washes

I have a plum tree that is producing fruit, but the leaves shriveled or curled almost immediately after the blooms fell. I noticed black spots inside the leaves, but nothing appeared to be alive. I found a Winter Wash that can be used to treat aphids, which can cause the type of curling I’m seeing, but I can’t find the wash in the US (simply called, Winter Tree Wash). Any other tips on how I can treat this tree to save both the tree and its fruit?

We like using neem oil for treating pests, as well as fungal problems. It is both effective and safe to use. Here is more information: http://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
