For people already growing something who are not sure what to do next. One topic per guide, something you can act on.
The same yellow leaf can mean nitrogen, magnesium, iron, waterlogging or an alkaline soil — and the fixes point in opposite directions.
Botrytis is not random: cool air, high humidity, poor ventilation and dead flower/leaf debris together bring it on. Prevention is almost entirely the first three.
One of the quickest greens: direct-sown in autumn, ready in 25–35 days. Three things matter — thin early, water evenly, feed lightly.
On sandy soil the problem is rarely a lack of water — it is that water never reaches the roots. A hard surface crust and the furrow carry it away, so the more you pour, the faster it goes.
Seedlings with tiny pinprick holes across the cotyledons and notched true leaves are usually facing flea beetle. It targets the seedling stage and can clear a patch in days; the adults are easy to spot, the larvae in the soil are not.
The same seed packet needs different handling: broadcasting saves labour but forces early thinning, drilling is easier to manage and uses less seed, and thick sowing plus transplanting has to happen at the seedling stage. Pick wrong and you spend the season catching up.
Bought seedlings most often fail in their first three days — not because they are hard to grow, but because the root ball was handled wrong, they went in too deep, or they hit full sun before acclimatising.
A bud that yellows and falls and a bloom that finishes and withers are two different things. The first is almost always caused by a sudden change in conditions, especially heat with no airflow; the second needs no action.
On any pesticide packet three things decide its use: the formulation decides how you apply it (spray, broadcast, or drench), the registered crop decides whether it may go on vegetables at all, and the pre-harvest interval decides when you can pick. Miss those and every later step is wasted.
Most strawberry seedlings that die after transplanting were not poor plants — they were set too deep or too shallow. The standard is one line: the crown level with the soil surface, never burying the heart and never exposing the roots. After the settling water, one day shows you which are buried and which are exposed; a buried heart can still be saved by washing the soil away the same day.
