Plant Growing Guides
The core skills every gardener needs: sowing, transplanting, watering, potting mix, propagation and year-round planting timing - one complete learning path.
What single change most improves beginner success rates?
Sowing by soil temperature with a thermometer instead of by calendar date. It fixes germination speed and reduces rot in one stroke.
How do I know if my seed is still viable?
Place ten seeds on a damp paper towel in a warm spot for a week. Eight sprouting means ~80% viability — sow thickly or buy fresh accordingly.
Is bottom watering always better?
It is best for trays and dense foliage, keeping leaves dry and damping-off risk low. Established pots water normally from the top until drainage.
