Put the umbrella in and tighten up the screw? If the size is way off, you could buy the right size of PVC pipe, say 1" and slip it into the sleeve and slip the umbrella inside that.

I bought a dark brown colored square granite umbrella base at Costco about 5-6 weeks ago.. just opened the box and slid it under the table today... It looks pretty nice and it's heavy.. there are two small wheels on one side (concealed underneth) and a fold down handle on the other,,, cost about $35.00 if I remember correctly... it's about 2" tall, so it sits fairly low... Just another suggestion.. Ben

I should have mentioned this. That pic was from last summer when we first got it. Initially we slipped the iron base beneath the deck railing for stability. It worked until one day when we got strong wind gusts (it's a 2nd story deck) and I saw the base had been pulled out and the umbrella looked like it was ready to launch. I ran to grab it and thought I was going to levitate like Mary Poppins! So now we have it secured - as was recommended on the instructions - with four patio blocks that fit in notches on the base. No issues at all since then. here's a pic of the base and one with it closed. Not too droopy, IMO

Hi Ken - The soil testing service is offered through the OSU extension office of Butler County. The soil was amended with organic compost and was planted just slightly above grade. I see what looks like new growth but the browning is happening more aggressively than the new growth. The tree has 2 equally sized trunks coming up from the main trunk. The landscaping company who planted it asked the nursery about this and they said it is normal for an Umbrella Pine. Although I have a sprinkler system I've been using a hose with a spray nozzle on the soaker setting. Lately we've had so much rain I haven't had to water it. I'm not sure what "perking" the soil is but the installer did come back to look at it and added more organic compost. The color is greener but the browning is still occurring and always in the same area so I'm hopeful the soil test will identify some nutrient deficiency that can be addressed. JT Benitez at the OSU Butler County Extension also told me to give him a call when I got the soil test results. Everyone is rooting for this tree to pull through. I'll keep you posted. Let me know if want to see additional pictures. Thanks again
