Spring Garden Tips: Where to Start When Your Garden Wakes Up
By Damian Stenzel, Founder
Spring is almost here, and your garden is about to go from winter survival mode to full growth mode. Before you reach for the fertiliser and start feeding everything in sight, do me a favour: go outside and look at what it’s actually telling you.
I’ve watched a lot of gardeners make the same mistake this time of year. Spring arrives, panic sets in, and everything gets fed the same way on the same day. Your garden doesn’t work like that. One corner gets more sun than another. One bed has been feeding plants for years and is running on empty. A pot plant is fighting for resources in a way a plant in open ground never has to.
These spring garden tips aren’t a shopping list. They’re about learning to read your garden before deciding what it needs — sunlight, soil, plant type, root health, all of it plays a part. Once you know what’s actually going on, feeding it properly is the easy part.
Consider this your spring reset. Before everything starts growing like crazy, let’s work out what your garden actually needs to do it properly.
Before You Feed, Take a Walk Around
Spring gardening doesn’t need to start with a trip to the garden centre and a trolley full of things you’re not sure you need. I’d honestly rather you didn’t buy anything from us today.
Start with a walk instead.
Take a proper look at your garden and notice what’s changed over winter. Are some areas sparse? Are certain plants growing slower than their neighbours? Are the leaves pale, yellow or curled? Is one section thriving while another has completely given up?
These are all clues.
Your garden is constantly telling you something about soil health, nutrition, sunlight and moisture. The trick is learning to read it before you reach for the fertiliser.
Walk your garden in sections and note anything that looks different. A healthy garden doesn’t mean every plant looks identical — different plants have different needs, and even the same plant can need different things depending on where it’s growing.
Not Every Patch of Green Needs the Same Thing
One of the easiest gardening mistakes is assuming that if one area needs feeding, the whole garden does too.
It might not.
A bed that gets less sun will naturally grow slower than one that gets several hours of direct light. A plant under a tree is competing for water, nutrients and light with the tree itself. A potted plant has a far smaller growing environment than something in open soil.
Then there’s the soil.
Soil nutrition varies considerably across a garden. Some areas have plenty of organic matter and active biology. Others are compacted, depleted, or simply short on what plants need.
Spring prep is less about feeding everything and more about understanding what’s actually happening in each spot.
Sometimes the answer is more nitrogen. Sometimes it’s better root development. Sometimes your soil needs more biological activity. And sometimes your plant just needs more sunlight.
Yes, unfortunately, fertiliser cannot negotiate with a tree.
Sunlight Is the Most Underrated Garden Feed
Most people think about plant nutrition purely in terms of what goes into the soil. I get it — that’s the part you can buy in a bottle. But sunlight plays just as big a role, and nobody’s selling that.
Plants need light for photosynthesis — it’s where they get the energy to grow. A plant in full sun can behave very differently to one in shade, even on identical feed.
As spring approaches, watch how sunlight moves across your garden. Trees, walls, fences and buildings all cast shade that shifts with the seasons. A spot that got decent sun in summer may behave differently now.
If you notice slower grass growth, sparse foliage or a plant lagging behind its neighbours, check its environment before assuming it’s a nutrient deficiency.
Good garden care starts with getting the basics right.
Read the Leaves Before You Reach for the Feed
Your plants can’t send you a WhatsApp when something’s wrong, so their leaves do the talking.
Yellowing leaves, weak stems, slow growth, pale foliage and poor flowering can all point to stress. Nutrient deficiencies play a role, but they’re not always the whole story — overwatering, underwatering, poor drainage, compacted soil, insufficient sunlight and damaged roots can all cause the same symptoms.
This is where plant nutrition stops being about throwing nutrients at a problem and starts being about understanding what your plant actually needs.
Nitrogen drives healthy vegetative growth — it’s the nutrient behind lush foliage and strong development. It’s why a slow release nitrogen source like our NC32 (32% nitrogen, carbon bound so it releases steadily instead of leaching straight through your soil) outperforms a quick nitrogen hit that’s gone in a week. Potassium, calcium and magnesium matter just as much, playing their part in plant structure, flowering and overall health.
The goal is balance, not volume.
More fertiliser doesn’t automatically mean more growth. Plants need the right nutrients, in the right amounts, at the right stage.
Spring Starts Underground
While the leaves get all the attention, there’s a lot happening underneath the soil.
Healthy root development is one of the foundations of good gardening. Strong roots help plants access water and nutrients, establish themselves in the growing medium, and cope better under stress.
This is where soil biology matters. Healthy soil is more than dirt holding your plants upright — it’s a living environment full of microorganisms and organic matter that drive nutrient cycling and availability.
My brother Ryan and I built Umya around that idea: feed the soil biology, not just the plant, and the plant looks after itself. It’s why our Bio Blend carries more than 30 beneficial soil microorganisms rather than a single strain — a healthy root zone is a diverse one.
Spring is a great time to focus on the root zone, especially when you’re establishing young plants or prepping pots, beds and containers for the new season.
The Root Care Pack brings together Pot Radix, Bio Blend, CalMag Essential and Multi Foliar to support early development, root growth and nutrient uptake. Think of it as giving your plants a proper foundation before you ask them to put on a growth spurt.

Choose Your Feed Based on What Your Plant Is Doing
Once you understand what your garden actually needs, choosing the right fertiliser gets a lot easier.
Young plants and newly established roots need different support to a plant already producing lots of foliage. A flowering plant has different needs again.
For plants establishing themselves, the Root Care Pack focuses on the root zone and growing medium.
Once plants move into vigorous vegetative growth, the Grow Care Pack supports lush foliage, stronger stems and steady nutrient availability, combining Pot Grow, Bio Blend, CalMag Essential and NC32.
Then comes flowering.
The Flower Care Pack is built for bloom — Pot Flora, Carbon K, Bio Blend and CalMag Essential work together to support flower and fruit development while keeping plant structure and nutrient availability on track. Carbon K alone carries 45% organic, water soluble potassium, which is doing a lot of the heavy lifting through flowering and fruit set.
The important thing isn’t choosing a fertiliser because the packaging looks convincing — plenty do, and most of them are guessing at what your plant needs. Match your feed to the stage of growth your plant is actually in.
Carbon Is Not Just for the Compost Pile
I can’t talk about healthy soil without talking about carbon. It’s the reason “Carbon” is in Umya’s name in the first place.
Carbon drives soil health and biological activity, which makes it a genuinely useful part of a broader soil nutrition programme — not just an afterthought for the compost heap.
The Carbon Starter Pack combines water soluble base nutrients built to support plants from early development through vegetative growth and flowering — a balanced nutritional foundation for the whole season.
For gardeners after broader support, the Carbon Powder Pack combines five water soluble products to support root development, vegetative growth, flowering, bloom and fruit development, plus soil health.
Both work across a wide range of South African garden favourites — herbs, leafy greens, flowering plants, indoor ornamentals, indigenous plants and perennials.
Your Spring Garden Checklist
Before you declare your garden ready for spring, take five minutes to check the basics.
- Look at how much sunlight each area receives
- Check for slow, sparse or uneven growth
- Look at leaves for signs of stress
- Check your soil and root zones
- Consider moisture and drainage
- Identify what stage each plant is in
- Match your feed to that stage
- Avoid feeding more simply because spring has arrived
The best spring garden prep isn’t about doing everything at once. It’s about paying attention.
Give your plants the right environment, build healthy soil, support strong roots and provide the nutrients they need when they need them.
Spring is when your garden wakes up. Your job is to make sure it has everything it needs for the season ahead.

Not sure what your garden needs yet? Start by looking at the plant, the soil and the growing environment. Once you know whether you’re establishing roots, building vegetative growth or preparing for flowers and fruit, choosing the right Umya pack gets a lot easier.
Spring Starts With a Little Preparation
Your garden doesn’t need a personality transplant before spring. It needs you to pay attention to it for five minutes before you feed it.
That’s it. That’s the whole system. Walk around, look at your plants, check your soil, notice the areas that are struggling, and ask why before assuming they’re hungry.
From there, match your feed to what your plants are actually doing. Build strong roots, support healthy vegetative growth, and switch up your feeding as plants move into flowering and fruit.
I’ve said it before and I’ll say it again: feed what the plant actually needs, not what the packaging tells you to buy. Good soil health, nutrient availability, root development and soil biology all work together — that’s true whether you’re running a farm or tending three pots on a balcony.
So before spring properly kicks off, give your garden a little attention now. A bit of preparation today means healthier growth, stronger plants and a much better looking garden once everything gets going.
Spring is coming. Your garden is ready. Are you?
