Are roots strong enough?

I planted my plants in the ground yester day and dug a fair size hole. The hole isn't big enough for the roots to grow fully in the hole i dug. I poured osme soil into the hole but the dirt in the holes beyond the soil is really hard. When the plant grows bigger will the roots get strong enough to grow thru this dirt?

They will most probably grow out rather than down. If its that hard

is that a bad thing?

I always dig my holes the depth of a five gallon bucket. Plenty of room. Gotta be careful though when planting in such dense soil. even though you dig a big hole and fill it with the best dirt. When you water it. it will turn to a small pond. Make sure its drying out good between waterings

No its not bad at all. The should do fine. How deep is the hole
