The following is my list of what I can sow/plant in my garden in April. Where you live may have different conditions, but this could be a good starting point for you to investigate or experiment to see what does well in your garden when planted in April.
Keep in mind, for a lot of plants growth slows to almost a complete halt once the daylight length gets below 10 hours a day. So it's important to get plants established enough before winter to provide edibles over winter, when new growth isn't really happening.
Cavolo nero (Tuscan Kale)
Bok choy/pak choi
Leaf lettuce- all varieties
Broccoli - sprouting
Zucchini - greenhouse only
Kohl rabi (seedlings)
Daffodils and other spring bulbs
Get Ready For...
Some folk plant allium plants from April onwards. I prefer to wait a bit later. But at least be thinking about and have on hand the following ready to plant (my preferred planting times in brackets): Shallots (May-August), Garlic (May-July), Egyptian Walking Onions (May-August), Onion seed (June/July).
Key Tasks This Month:
- Clearing away spent plants and weeds
- Spreading compost/manure/mulch on beds
- Covering beds that will not be used over winter with thick mulch and/or a light-excluder such as old carpet or black plastic
- Harvesting and preserving/storing produce - in my garden that's mainly pumpkins, watermelons, quince, potatoes, tomatoes, cucumbers, beans, beetroot, spaghetti squash, nasturtiums, some late berries & grapes, marrows, late sweetcorn and chestnuts
- Collecting and drying seeds from flowers and herbs
- Cutting and drying herbs (if you wish - I don't generally bother as there are plenty of fresh herbs available in the garden all year round).
- Pruning away spent raspberry canes and bramble vines (blackberry/boysenberry)
- Making compost piles - as much as you can!
- Prune and mulch citrus - and feed if in warmer areas (not down south)
- Sharpening up the pruning tools and making a list of what needs pruning when - pruning done at the right time, a lot of it in winter, sets plants and trees up for good producing next season.
