Fun, pretty square. A few mistakes in pattern but the square is intuitive enough there shouldn’t be any problems. Still, made notes below on Round corrections.
Made a 9” square using 1 main 6” square and 5 motif 2.75” squares.
Main 6” square: SS yarn & G hook stopped @ Rnd 9 (done with Blue Mint)
2.75” motifs: Went down to F hook and worked through Rnd 4 (in Grass Green).
Joined motifs & main 6” square with overcast st & Blue Mint; also overcast outside border of motifs.
Border: G hook & peach worked Rnd 10 as written around 6” border. F hook & peach worked Rnd 10 around motifs and replaced “dc in next 2” with “dc2tog” twice per square.

Round corrections (shown in Bold):
Rnd 3: Join Colour B with a * sc to a back bump of one of the petals, ch 2, trc between two petals into the sc from Rnd 1, ch 2, * (delete the following: sc into top of next petal) repeat from * to * five more times, sl st into beg sc. (6 sc, 6 trc, 12 ch-2 sp)
Rnd 4: Ch 2 (as hdc), * 2 hdc into ch-2 sp, hdc into trc, 2 hdc into next ch-2 sp, hdc into sc, repeat from * around to last ch-2 sp, 2 hdc into ch-2 sp, sl st into top of beg ch-2. (36 hdc)
Rnd 5: Ch 1, sc into same st, sc in next st, hdc in next 2, dc into next, * corner as (dc, trc, ch 1, trc, dc) in next st, dc in next, hdc in next 2, sc in next 2, hdc in next 2, dc in next, * repeat from * to * two more times, corner in next st, dc in next, hdc in next 2, sl st into beg sc, fasten off colour B. (4 corners, 8 dc, 16 hdc, 8 sc) (12 st + 2 ch-1 sp each side)
Rnd 10: Join colour A with a sl st in corner ch-2 sp, ch 3 (as dc), dc, ch 2, 2 dc in same sp (corner made), sk 2 st, * ~(ch 1, sk 1 st, dc in next 2 st) seven times, ch 1, sk 2 st ~, (2 dc, ch 2, 2 dc) in ch-2 corner sp * , rep between * three times, repeat between ~ once, sl st into top of beg ch-3, fasten off color A. (72 dc, 32 ch-1 sp, 4 ch-2 corner sp)
