An April Garden: Notes for Spring | Hortiwool

There's a moment in April, you'll know it when it arrives, when you step outside in the morning and the garden feels genuinely different. The light has changed. The birds are making an extraordinary amount of noise. And something that's been quietly coiled up all winter finally starts to move.

Here at Hortiwool in Staffordshire, April is the month we live for. It's not the tidiest month, and it's certainly not the most predictable, but it has an energy to it that no other time of year quite matches. After months of seed catalogues, planning, and willing the soil to warm up, April is where the growing year actually begins in earnest.

This month we wanted to do something a little different. Rather than a straightforward growing guide, we thought we'd share what's actually going on in our gardens right now, what we're sowing, what we're planting, what's demanding attention, along with a few things we've learnt along the way.

The Greenhouse Is Starting to Feel Alive Again

The greenhouse is where April really begins for us. Right now it's home to trays of tomatoes that we started in mid-March, and they're coming along beautifully, three varieties this year, including our perennial favourite Gardener's Delight and the extraordinary Sungold, which produces sweet orange cherry tomatoes that taste almost tropical when the sun's been on them all day.

Peppers and chillies are in there too, a little slower off the mark as always, but starting to get going. If you haven't sown peppers and chillies yet, don't panic, there's still time in early April, but get them in as soon as you can. They need a long growing season and they really don't like to be hurried.

One thing we've been doing differently this year is placing Hortiwool beneath our seed trays throughout the germination stage. The difference in moisture consistency at the base of the trays has been noticeable, no dry patches pulling away from the sides of modules, no soggy centres that never quite drain. For seedlings at this delicate stage, that kind of steady, regulated moisture is genuinely valuable. It's also deeply satisfying to know that as the wool slowly breaks down, it's releasing nitrates into the soil which helps to feed the plants.

What We're Sowing Outside

The soil is slowly getting warmer and we've been patient, possibly more patient than usual, which doesn't come naturally, but it's paid off. Cold soil is no place for seeds, no matter how urgently you want to get them in.

Rosie has bought a new raised bed where she is going to use cardboard, sticks and soil from the garden to then plant beans, potatoes, lettuce and peppers! We can't wait to see what comes from her kitchen garden.

Georgie has started to plant some violas which have been propagated from other pots which are bringing her garden a lot of colour and happiness to the start of spring. Next on the list is to start some hanging baskets. 

Luke has made a bug box with Hortiwool inside which has been attracting the birds. Hortiwool is perfect for a nesting material as it is 100% pure wool. A lot of tulips and daffodils are coming through to make an appearance for spring and Lukes job for the end of April is to make some hanging baskets where he can also give Georgie some tips whilst he's putting them together.

If you're wanting to start sowing outdoors this month, carrots, beetroot, spinach, radish, lettuce, spring onions, and, towards the end of April as the soil warms further, French beans and courgettes in a sheltered spot are good places to start.

The Fruit Garden

The raspberry canes planted last autumn are breaking into leaf, which is always a relief, bare-root plants have a way of looking entirely dead for longer than feels comfortable. The gooseberry bushes are ahead of them, covered in fresh pale green growth, and the apple and pear trees are in full blossom right now, which is one of our very favourite things about this time of year.

If you haven't yet planted summer-fruiting strawberries, April is a good time to get them in. We always tuck a Hortiwool Garden Pad beneath the plants at planting time, it suppresses weeds, helps retain moisture around the roots, and keeps the developing fruits clean and off the soil later in the season. It's one of those small additions that earns its place quietly.

Blueberries can go in now too, as long as you're planting into ericaceous compost or acidic soil. They're long-lived, low-maintenance, and the birds will absolutely try to take the lot, so get your netting plans in order sooner rather than later.

April Jobs We're Getting On With

Beyond the sowing and planting, April comes with a fairly substantial to-do list. Here's what we're working through:

Hardening off seedlings - Anything started indoors, tomatoes, peppers, courgettes, squash, needs to be gradually introduced to outdoor conditions before it goes out into the world properly. We put trays outside during the day and bring them back in at night, over a period of one to two weeks. It sounds fiddly, but plants that have been hardened off properly establish so much more strongly than those that haven't.

Potting on - Seedlings grow fast in April and they exhaust the nutrients in seed compost quickly. If roots are starting to circle the bottom of modules or small pots, it's time to move them up. Don't leave them sitting too long at this stage, a plant that's been in a pot too small for too long takes time to recover.

Mulching beds - With the soil warming up, now is a good time to apply mulch to borders and vegetable beds. It conserves moisture as the drier months approach, suppresses emerging weeds before they get a foothold, and improves the soil as it breaks down. Hortiwool Garden Pads work brilliantly as a compostable mulch layer; laid around plants and beneath the surface, they regulate moisture and release nutrients naturally as they decompose. No plastics, no synthetics, nothing that doesn't belong in your soil.

Weeding - Its not our favourite job (not that its anyone's right?) but weeds are awake and moving fast in April. Little and often is genuinely the most effective approach here, ten minutes every few days keeps things manageable in a way that one heroic Saturday session simply can't.

Checking overwintered plants - It's worth going through any plants that came through winter under fleece or in the cold greenhouse, removing dead material, and assessing what's made it. Some things surprise you. Others don't make it and that's fine. Note what happened and try something different.

Feeding containers and pots - Plants in containers can't access nutrients from the wider soil, so once growth gets going properly, they'll need a regular liquid feed. Start now and keep it up weekly through the growing season.

A Few Words on Slowing Down

We'll be honest, April used to feel like a bit of a scramble. The list of things to do always felt longer than the hours available, and there was a constant nagging sense of being behind. What we've learnt over the years is that the garden rarely rewards panic. Plants sown into well-prepared soil at the right moment outperform those rushed in two weeks earlier every single time. A bed properly mulched does more work quietly than a bed frantically attended to.

There's also a lot of joy in simply being out there, noticing things. The self-seeded aquilegia that's appeared in an unexpected corner. The bees working the fruit blossom with obvious dedication. The smell of the soil after rain. These things don't show up in a growing guide, but they're part of why we do this.

April is generous, if you give it room to be.
