Heat Today will be hot in the south of the Netherlands: up to 30 degrees! Check whether your reservoir is still full, whether the mix is still moist, shade vulnerable plants around midday, and wait with sowing until it cools down.
Buy vegetable seedlings or not?
It is early April. Just look at my plants shooting up:
'Erm, Jelle, mine does not look like that yet. What am I doing wrong?'
Nothing. I simply visited my local garden centre yesterday 🙂
At this time of year, they already have a good selection of small herb and vegetable plants.
In a cold March, you may not be able to start sowing until late in the month. Any seedlings that have appeared by April are probably still very small.
Put a few young plants in your raised bed now and you can start harvesting in just a few weeks.
Where can you buy seedlings?
Which vegetable plants are good?
By the time I can plant those at the end of May, I will have harvested this lettuce long ago.
I also buy a few fennel and kohlrabi plants. A handful of each is more than enough for me. Planting them now gives me a good chance of harvesting them before butterfly season.
Which seedlings should you avoid?
Beetroot seedlings, rocket and lamb's lettuce: I always prefer to sow these myself.
All the other brassicas: cauliflower, broccoli, red cabbage, white cabbage, kale and pointed cabbage.
Trust me: they are nothing but trouble. They grow too large, occupy your raised bed for far too long and always get eaten by something.
All summer vegetables: chillies, tomatoes, sweet peppers, cucumbers, aubergines and courgettes.
The plants are already on sale, but it is far too early to put them outside. One cold night and they are done for.
Unless you have a heated greenhouse, it is better to leave them where they are until the end of May, when it is finally warm enough outside.
And herbs: should you buy those now too?
You can buy lovely small parsley plants for very little. Put four in one square and you will have enough for the rest of the year.
All the chive plants you see in my pictures are all descended from the first plant I started with 10 years ago.
But stay away from basil, because it really hates cold weather. It's much better to sow the seeds and let the plant grow that way. Same goes for cilantro.
How do you plant the small plants?
Use a trowel to make a hole in the MM-mix by pushing it aside, then put in the plant with its root ball. Gently press the MM-mix back around it. Do not press too firmly because the mix should stay airy.
Large plants should be placed in water while still in their pots. This also makes them much easier to remove.
Cut the bottom centimetre from the root ball straight away. This encourages the plant to make new roots quickly.
Then put the plant in your raised bed, or in an MM-mini.
Prefer planting to sowing?
But for a flying start, neither is crazy: you buy a few plants and sow the rest.
For sowing I have some very nice packages 😉
