Hi new gardener here so pardon me if this question has been asked before.

According to www.ffxivgardening.com, planting an almond seed next to honey lemon gives you a chance for an apricot seed. I understand that using grade 3 thanalan soil increases the chance of this happening. My question is should I use the thanalan soil for both patches or just the second one (almond)? If I use a cheaper soil for the honey lemon patch, will it decrease the chances of crossbreeding?
