Recently you quoted question 3260 regarding one that buys flowers for home every Friday Lik’vod (in honor of) Shabbos, if he should also do so for Shabbos Chazon, (Shabbos before Tisha Beav), and mentioned that “Horav Shlomo Miller’s Shlit’a opinion is that although it is not exactly the same as planting new flowers, it is still better to avoid even just buying them on Shabbos Chazon.” Is this true even if you buy them every Shabbos?

It is what Horav Shlomo Miller’s Shlit’a mentioned. (See Piskei Teshuvos 551: 4: n. 39)
