Hi there,

My first time try gardening with seeds. I just put out my tomatoes and basil out last week. They're starting to yellow/brown.

- Conditions: BC weather has started getting pretty hot (28 degrees)
- I did about a week of hardening
- I water them once a day in the morning
- they are in fresh potting soil

Do you know what's wrong with them? Any chance they'll survive?

If you have any idea or suggestions. Let me know, really appreciate it.

Due to overwatering also leaves turn yellow. The right balance of water and sunlight helps seedlings to grow. If your soil is moist you don't have to water it. So before watering check if the soil is moist or dry by touching the soil.

In your climate, watering every day is too much. They should never dry out too much but you can't grow them soggy either.
As far as yellowing leaves go, that is to be expected. Hardening off helps them adjust to the outdoors but it can't prevent leaf loss. Be patient, they will improve.

They are adjusting to more sunshine and heat. The new growth looks good and that's really all that counts.

Keep the soil evenly damp - how often you water depends upon your climate, the size of your containers and how quickly the potting soil you used dries. My veggies are in the ground, my temperatures are very close to yours right now (they'll get hotter) and I water everyday. If the soil does nnot stay evenly damp, your tomatoes will develop blossom end rot.

Don't fertilize until you check the potting soil bag. Lots of potting soils come with built in fertilizer. I use Miracle Gro Potting soil for my container veggies, it has enough fertilizer to last the summer.

If it doesn't have added fertilizer, you will have to add some eventually (but not quite yet). Don't fertilize the basil at all - it loses its flavor when fertilized.

PS: your veggies are not showing any signs of overwatering, just some sunburn. Thumbs up
