Home Depot’s 2019 mulch sale appears to have run around mid-May through Memorial Day , with one 2019 deal posting a May 20–May 22 window and another source describing the Memorial Day savings event ending May 22. A separate 2019 July 4 promotion also offered mulch at 5 for $10 starting in late June and running into early July.

What that means

  • Spring 2019 timing: around May 20–22 for the Memorial Day sale.
  • Another 2019 mulch promo: around late June to July 10 for the July 4 sale.
  • Typical pattern: Home Depot mulch discounts often show up during spring holiday events and again around summer holiday sales.

Quick note

If you were asking about the usual Home Depot mulch sale timing rather than 2019 specifically, the pattern tends to be early spring and holiday weekends.

TL;DR: In 2019, the big Home Depot mulch sale was most clearly around Memorial Day in mid-to-late May , with another mulch deal later around the July 4 period.
