To make a burger in the game "Grow a Garden" (a farming simulator game on Roblox), you need to follow these steps:

1. Gather the required ingredients. There are multiple recipes for making a burger:
   • Rare burger: 1 Pepper, 1 Corn, 1 Tomato, and 1 Mint (optional filler).
   • Legendary burger: 1 Corn, 1 Tomato, plus either 1 Ember Lily or 1 Beanstalk and 1 Cactus.
   • Mythical burger: 1 Pepper, 1 Corn, 1 Tomato, and 1 Bone Blossom.
   • Divine burger: 1 Corn, 1 Tomato, and 3 Bone Blossoms.
2. Approach Chris P. Bacon, the pig NPC wearing a chef’s hat in the kitchen area of the game.
3. When Chris P. Bacon prompts you to cook a burger, put the ingredients in the cauldron next to him.
4. Select the green cook button to start cooking.
5. The cooking time is about 10 minutes and 32 seconds. The pot color must be red for the burger.
6. Once cooking is finished, present the burger to Chris P. Bacon to receive rewards. If he is craving a burger, the rewards are even better.

This cooking mechanic is part of the Grow a Garden Trading and Cooking Event Update, where players can use homegrown produce to cook various dishes to trade and earn rewards in the game.

If you are asking how to literally grow a garden as in planting and gardening, then the general approach is:

• Choose a garden location and clear the space.
• Design the garden layout with raised beds and pathways.
• Fill beds with nutrient-rich soil.
• Plant seeds or seedlings suitable for your climate.
• Water and maintain your garden regularly by weeding, pruning, and protecting from pests.

This general gardening advice can help you grow vegetables and herbs that you might use in real-world cooking, but in the game, the ingredients come from your virtual garden.
