Why does my tree have tumors?

Hello - I have a tree in my back yard (unsure of species) that is covered in odd shaped "tumors". These shed from the tree periodically and are very painful to step on when barefooted. Can you help me understand what these objects might be and if possibly, if there is any "tree-tment" available?

Thank you!

Turf for Church Soccer Field and Playground

Good Afternoon ~ Our church is seeking information on turf varieties that would stand up to neighborhood use by children of all ages as a soccer/football/baseball field. Some consideration has already been given to artificial turf. Currently there is not an irrigation system on the area intended for the sports field. Can you please recommend some options we can research and which would help in the church's decision for improving the area. Thank you.

Best Cukes

Last year we had a bumper crop of cucumbers from our garden - however, most were extremely bitter. So bitter, that we ended up composting most of them. I did look online for tips and learned that irregular watering could cause this but also some types of cukes are more prone to becoming bitter than others. So now I’m wondering which cukes are best for flavor and sturdiness here in our Boulder Colorado garden. Thanks so much!

Treating cedar planter boxes for organic gardening

I have purchased raised cedar planter boxes for vegetable gardening. I am treating the inside with vegetable oil. However, I would like a product that gives more protection to the box for weathering on the outside. Can you recommend a product that is natural and will not leach through to the soil inside the box or is safe for the vegetables?

Pruning Tam Junipers

We live in Denver. Our backyard has ten lust (4 feet tall and sprawling) tam junipers that border the fence. They need pruning. I have instructions on how to do this and avoid dead spaces and encourage new growth. When should I begin the pruning--now, first part of May, last part of May, or June?

Thanks

Tomato virus in soil?

We have been growing tomatoes in a small garden for many years (supplemented by compost). The last 2 years production was stifled by leaves wilting and drying. My spouse thinks it's because a virus lays dormant in the soil and wants to remove the top layer of soil (3-6").

Your thoughts?
