@EmmaKone… very frustrating to be disappointed when planting a new garden. In many ways that is the story of how gardeners learn. Now you know what not to plant. I have planted a lot of goobers in my garden.do you know your growing zone.
The best advice I can share with you is know your growing zone, plants that thrive where you live. Learn what plants grow in shade and full sun. Annuals perinneals and bi annuals are the many flowering plants. There are bulbs, corns, tubers and many plants that do well only when planted past the last frost every year . It's all a learning experience.
Over the winters study the plant catalogs many online to order plants as they show the plant , growing zone, shade plants or sun plants. Etc. soil conditions is important learn about soil for garden plants. Lots of online articles and books.
A lot of garden magazines have directions on styling a garden. They show Garden beds in different growing zones as well as big box stores have books that help with planting different types of garden beds for different growing seasons and zones planned out examples as well as directions on how to style your own garden, best time to plant and advice on managing a garden and veggies.They have great layout designs of garden beds as well as many trees and shrubs, the back bone of the garden.
Planning on paper and start out small and once you get the idea it all falls into place.
There are many great computer programs that can help advise you as well as locate plants for your area and watering systems. Try googling a few and you will be surprised.
Also ask if your area has a garden club. Call the county extension service for a garden club near you. There are many experienced gardeners that meet monthly, go garden on garden tours and teach the fundamentals of gardening, have access to special prices on plants from nurseries, share plants as well as finding great friends.
After a couple of growing seasons you'll be a pro.
