If you wanna save some money, start your garden from seeds. Now it takes more planning and patience but yes you will save some coins. I’m still using the seeds I purchased back in 2018 and 19 for my garden this year. From what I gather some seeds do have an expiration date but if you store them properly they should be fine.
Soil ( I use the seed starting soil from Miracle grow)
Seedling trays ( you can also repurpose water bottles and cardboard egg crates)
If you're starting your seeds indoors its optional to have a heat or lighting source. I'll link the grow light I use here. For a heat source I use a regular space heater. Another perfectly fine source of light is natural sunlight. You can place your seedlings near a window and they will grow just fine.
When starting from seed it is important to plan, I mean it's not the end of the world if you don't but I can tell you from experience that you will either have too little or too many plants when it comes time to transplant. To plan my seedlings I use a little math and my crop list. Because I’m dedicated to sqft gardening I plant my seedlings based on how many of each crop can fit into my space. For example 2 cucumber plants can fit into one Sqft space, I’m growing 2 varieties of cucumbers so I need 4 plants total. I would plant six cucumber seeds, three of each variety.
Steps to the perfect plan
1.Prepare a crop List
2.Plan your planting space/ Grow beds
3. Prepare a list of how many of each crop you need
