Hungry vegetables, unsurprisingly, need regular feeding throughout the season. Topping the list of gluttons are tomatoes, peppers, cucumbers, zucchini, eggplant, squash, and pumpkins. Thankfully, it is quick and easy to get a good feeding regime going at the right time, and you’ll be rewarded with a bounty of harvests.
Once the plants start flowering, it's a signal to start feeding them weekly with a high-potassium fertilizer. This helps the plants to flower and fruit prolifically, rather than focus on developing excess leaves and stems. Well-fed plants will have all the nutrients to set and ripen lots of fruit.
