Check your strawberries regularly for weeds. Give strawberries a weekly dose of potassium-rich fertilizer dissolved in water. The first delicious strawberries are often ready for harvesting in June. Pick them with the crown attached, as they will then stay fresh for longer. This also prevents mould from developing on the plant.
If you have ever grown your own tomatoes, you are probably aware that tomato plants grow very rapidly and need to be kept under control. However, you should not remove the top as this will prevent the plant from producing new flower buds.
