When you have seedlings, one of your first hurdles is to transfer your hard-grown plants outside so they can continue growing.
During this process, where you move from from their pots to a bigger area of soil so they have more room to go, you have to be careful to give them their best possible chance of survival.
You will want to create holes for each of your seedlings in the soil, and make sure there's enough space between them so they can grow independently.
