Concerned about slow growth of my seedlings

I'm by no means an expert, however I am pretty sure that, at least for Zucchini, Cucumber and peppers 1% more light = 1% more growth. Thus in order to increase growth, maybe you should start moving ...

What to do if too many seedlings are in the same pot?

You seem to have more than a hundred seedlings overall. Are you willing to grow every single one of them into adult plants? I'm assuming not. If that's the case, you'll be discarding them at a later ...

What's the best pot size for rose seeds germinated in the refrigerator?

All plants should have pots matching the plant size, otherwise you risk root-bound plants or trouble with watering. That's why we re-pot as needed and only go up a few pot sizes at a time. Roses like ...

Is using tomato slices really viable for starting seedlings?

Think of how tomatoes grow "in the wild" fruit drops to the ground, slowly rots, and when conditions are right a new plant emerges. So cut open the fruit and cover it in soil, the results are not ...

Do young plants prefer their pots be rotated?

Do they prefer it? No, not really. Plants have evolved to grow and orient themselves to get the most light in any given conditions. It could even be argued that turning them away from this orientation ...

Planting too many seeds in small pot

Your plants will have to compete with each other for light, and root space. Because they are so packed and crowded, none of the plants will grow optimal this way. If you just want basil cress, you can ...
