The summer update for the game "Grow a Garden" was released on June 21, 2025, at 7:00 AM PT. This update is a major one, featuring an overhaul of the Seed and Pet Shop, new events, new seed packs, gears, weather events, and a summer- themed community event called the Summer Harvest Event. Players can expect new summer crops, pets, mutations, cosmetics, and special events within the game starting from this date.
If the question pertains to general gardening in summer (outside the game), the summer update or activities in a real garden typically involve planting heat-tolerant varieties, regular watering, pest control, and harvesting summer crops like tomatoes, peppers, and beans. Succession planting may continue through June and July depending on the climate zone.
Please clarify if the question is about real garden seasonal changes or about the "Grow a Garden" game summer update.
