April is here and it is time for food growing! This month you can sow your outdoor seeds and herbs as well as harvesting some spring treats.

01 April 2021

  1. Chit and plant second early potatoes in the first half of the month and plant out main crop potatoes in the second half of the month.
  2. Indoors sow seeds of courgettes, pumpkins, squash, cucamelons and sweetcorn. This is the last month to sow peppers, chillies, cucumbers, celery, celeriac, summer cabbage, Brussel sprouts, leeks and outdoor tomatoes.
  3. This is the time to pot up your indoor tomato, pepper, chilli and cucumber plants now they have developed their true leaves. Ensure you support your plants with canes, twigs, sticks, string or twine to help them grow.
  4. Support pea and bean plants with sticks (pea sticks), canes, twigs and netting where needed. This will also help protect them from pests such as birds, which like to attack young plants.
  5. Forced rhubarb, spring onions and spring cauliflowers will all be ready to harvest. So it’s time for some yummy rhubarb pie!
  6. April is the time when late frosts can damage the flowers on fruit trees and bushes. Where possible, try to protect the flowers of apple, plum and pear trees on frosty nights while also allowing for pollination by insects during the day.
  7. Sow outdoor vegetable seeds such as; beetroot, broccoli, carrots, chard, Chinese cabbage, kale, kohl rabi, lettuce, radish, turnip, spring onions, peas, runner beans, French beans, summer cauliflower and perpetual spinach. Make sure you have prepared the soil, planting area or pots where you will be growing your vegetables.
  8. If you have a greenhouse or are growing indoors on a windowsill, now is the time to start keeping an eye out for plant pests. These common pests could be aphids, slugs, red spider mites, whiteflies and soil flies. All these pests can be found either on the leaves, plant stems, in the soil or under pots. We suggest trying biological and cultural (non-pesticide) controls if you have any pest infestations.
  9. Sow hardy annuals such as love-in-a-mist, marigolds, sweet peas, sunflowers and bedding plants. The sowing of hardy annuals could include companion plants such as borage, nasturtiums, coriander or parsley.
  10. It is the prime time to sow herbs such as basil, parsley, coriander, dill and chamomile. Remember to protect these newly grown herbs from pests such as slugs and snails, cloches are a great way to do this.
