I love Guys like you.Not worried about time commitment. I am going to remember that one. Your not going to be losing all your wood Garapa could sit in 10'' of slime and be the same inside for hmmmmmm 50 years or so. Time,Labor is no problem at all....Ok Set up a tarp outside and a couple of saw horses one by one use a hand scrub brush and a 5 gal bucket of Oxalic wash,no need for the stripper there is no finish on to strip off, put on some gloves and scrub,rinse, scrub, rinse, scrub,,, well you get the idea. Rinse again be very sure no oxalic is left on the lumber and take that one to the covered area where you have fans set up and stack it up with stickers. Be sure and do both sides and the edges. Do the next one. Be sure and keep them straight and leval. After 15 days or so with the fans runing,check everything every two hours, one by one sand all four sides with a makita 5'' random orbit 100 grit pads. Reason for this is that much oxalic is going to whisker up the Grappa. While sanding be sure and keep the edges beval the same, be very carefull. Stack each one up with out the spacers straight and leval. Bubble wrap the whole stack quickley keep all moisture out of the wrap, you can hook up your home vac to the wrapp as you go to suck out the air. Attention!!!! do not let the Sun hit this package. You now have a not bad stack of Lumber. Very close to the way it was delivered to You in the first place. But your not done Yet,,one by one take each one out Almost done but because you have stickerd it up you will have sticker Marks!!! Dammmmmm so sand it again with 120 grit be very carefull again, and install it. You will have to keep the vac going and close the wrapp each time thats a lot of duck tape but Hey!! youve gone this far Right?? After you have gone thru all of this there is a very good chance the project will look close to the same as installing the material just as it is then brushing it off with a deck broom and a light oxalic/water mixture. JonMon Edit... Now if your intention was to pre finish all four sides before install there are a few more steps to go through. All of them would be as useless as the rest of it.

It sounds like some large checking to me. I have samples of 1x4 Garapa, 1x6 Garapa and 5/4x6 Ipe and have left them out this summer to see how they act. The 5/4x6 Ipe held up great, very very small check cracking. The 1x6 Garapa had some cupping and moderate checking (although the thickness was quite a bit less that the 1x4 pieces of Garapa I have). The 1x4 Garapa held up pretty well. No noticeable cupping and some minor checking. I realize this is a very small sample, and the results are not that surprising. I tried to take pictures, but they didn't come out very well. Just curious, where did you get your Garapa from? I would also be curious to hear what others with Garapa decks are finding because I am planning on building a Garapa deck next spring and letting it go grey. Riles

Take a small soil sample with you and the Master Gardener(s) on duty at the Extension office will do a pH test for you, free, on the spot, will give you the results and recommendations on what to add if it is necessary to adjust the soil's pH level. This is important because the acidity/alkalinity of the soil will affect the plants' ability to uptake nutrients. Most veggies prefer a pH of about, if I remember correctly, 6.7-7. (7 is neutral). You can purchase a soil test kit to determine the nutrient levels in the soil. After you collect and package the soil and fill out the questionnaire (what you will be growing in that location), you return it to the Extension office and they'll send it to the Rutgers Soil Lab. You'll receive a complete analysis as well as recommendations for soil amendments for optimal soil conditions for your desired plantings. If you discuss your garden's problems with the Master Gardeners on duty, they may have some suggestions for you and can provide you with pertinent fact sheets. You can access these same fact sheets, free of charge, at www.njaes.rutgers.edu/garden. Crop rotation is advisable, but with very limited garden space myself, I understand it sometimes can be difficult. (I have a very small area that gets enough sun for tomatoes, so they have a choice: enough sun, or fresh soil.) However, it's probably worth the effort if you can move those stakes, or just put up a new set and use the old stakes to grow another crop vertically - pole beans, melons, cukes ...

@William NJzone6b The only way I know of to tag a responder with a reply is for the OP (you) to use the ”Thank” button available to only the OP. That generates an email notice to poster if they’ve set it up in their profile. Otherwise, just using ‘@‘ + choosing poster name from drop down as I did in this post with your name, alerts poster that reply is directed to them. Either way, any activity on posts one responds to is listed in the notification bell icon at top of Houzz discussion page. Whew! Long answer! I missed that you said planting border outside fence is 10’ wide. Sounds like the GG’s are best suited for your need. I looked them up for mature size & though Giants they are, they are shorter & narrower than the white pines you took out. But, the GG width - at base - is 12’ - 20’ so I’d increase the space between them beyond the 6’ I’m guessing your fence panels are & for sure plant them in middle of 10’ width. Seems like a solid view block really isn’t needed for the neighbors upstairs windows views - those are probably bedroom windows too. Theyhave their own trees at lower window height.
