This year, I’ve met more new gardeners than ever! It’s so exciting to see so many new faces, and I’m thrilled on your behalf as you start this exciting new foray into your backyard. With that said, gardens are about community. Even if it’s tucked away behind a fence, your garden is joined with the others in the neighbourhood through the wildlife, elements, and climate in our region—no one gardens in a bubble. So, in the spirit of community, I wanted to take the opportunity to help the beginners out there with this basic plant care guide. I’ve collected all the need-to-know info, as well as some links to other helpful articles, so it’s all in one place for you to reference. Here’s all you need to know to make your garden’s first year a smashing success!
Watering
When you bring your new plants home, watering them correctly is the most important part of helping them start their new lives in your garden. Here in Guelph, we’re starting up water bans, which has some folks a little nervous about how they’re going to keep their plants hydrated. If this is you, don’t worry! If you’re watering properly, you should be able to keep all your garden friends happy and stay well under your water budget. Here are some watering tips for beginners, broken down by plant type:
Annuals: Annual flowers kept in pots, containers, or hanging baskets don’t have a lot of soil to draw from, so it’s common to water them every other day, and daily in very hot weather. Water the soil, not the foliage, as much as possible, and keep the water running until you see it leak through the drainage holes on the bottom of the pot.

Perennials, Shrubs, and Trees: These are some of the most commonly returned items because they often need more water than people expect, but less frequently. These plants are working to establish deep, strong root systems that will sustain them through the winter. After planting, water them very deeply before mulching; you’ll want to run the hose for half an hour to forty-five minutes before moving it to the next plant. A weeping hose is great for watering at the soil level; you can purchase one at our nursery and set it up under the mulch. Repeat that deep watering with the weeping hose (or a hose kept very close to the soil) every 5-7 days.
Lawns: Right now is not the time to water your grass, even though bluegrass-based lawns are looking a little brown! The dull colour is a normal and healthy thing for this time of year, when bluegrass is dormant. Watering the grass will force it out of dormancy, and if that happens, you’ll need to keep up with much more watering and fertilizer than necessary in order to keep it alive. For now, save your water for your plants, and worry about lawn care until later on in the fall. We’ve got a whole fall lawn care guide you can refer to then!
A few extra watering tips:
- Always avoid getting water on the leaves and aim for the soil, instead! We have an expression, “Water the soil, not the plant.”
- The best time to water is early in the morning, and the second-best time is in the early evening.

Fertilizing
Many first-time gardeners are intimidated by fertilizer, and I can understand why—there’s a lot of information to digest. If you’re using fertilizers for the first time this year, don’t panic! Here are a few tips for getting it right.
- The ratios you see on fertilizer packages stand for the ratio of N (nitrogen), P (phosphorus), and K (potassium) in the formula, and their respective concentrations. It’s important to recognize that there’s no one-size-fits-all, “best” ratio—only the best formula for the plant you have.
- On that note, each plant has its own fertilizer needs, so reach out if you need help choosing the right one! Fertilizer labels will normally tell you exactly which plants they’re for, but our team can also help you pick a formula if you’re not sure.
- The most important step when applying fertilizer is to read the package directions. If you apply the fertilizer exactly as directed, you should be just fine.
- When in doubt, it’s better to use a little less fertilizer than too much.
- When using a liquid or water-soluble fertilizer, water your plants an hour or so before applying. This helps to protect plant roots from burning.
- The fertilizer packaging should tell you how often to apply the product, but if you need more information or anything is unclear, don’t hesitate to ask us! We care about your success.
- Enriching your soil by adding compost to it once or twice a year will help improve soil health, reducing the need for fertilizers in your garden beds over time.

Staking & Supports
Some plants can grow to be quite top-heavy, so we use stakes and supports to help them stay upright when bursting with blooms or flush with fruit. Tomatoes, delphiniums, lupines, and peonies are commonly supported with stakes or cages.
Tomatoes and peonies are most often supported in cages, which makes it easy to support the weight of their respective fruit and flowers as they grow. I always recommend fitting the cage on the new plant as early as possible. Position the stem in the middle, and over time, you can use the wire tiers to support the layers of foliage. These structures encourage the plants to grow upright, which will help you keep them evenly pruned on all sides.
We typically use stakes to help out a plant that is starting to buckle under its weight. If you have a plant with a flower spike that’s starting to lean, securing it to a stake will keep it upright and encourage the stem to grow stronger and straighter. You can use twine, wire, or even special clips as a tie to bind the plant stem to the stake.
When using stakes, be gentle with your ties; if they’re too tight, they can start to cut into the stem as it thickens. If you notice a tie starting to cut into the stem, remove it and replace it with a roomier one.

Pest & Disease Management
Pests and diseases are just part of the gardener’s journey. It’s easy to get discouraged when you find your precious plants’ leaves riddled with holes, but chin up! We’re working with nature, after all, and nature always has its own plans.
We can’t always predict when disease will strike, but we can always take steps to prevent it. Some important prevention tips to note include:
- Again, watering the soil, not the plant! The reason why I recommend this so strongly is because plant diseases love wet leaves. Wet foliage is a perfect breeding ground for infections to develop.
- Keep your plants pruned to promote airflow through the leaves. For example, if the plant leaves are starting to press upon each other, it’s hard for moisture to evaporate there, leaving the area vulnerable to infection.
- Similarly, watch for stems that rub against each other; this can cause abrasions that let disease in. You can read more about this in our pruning guide.
- If you notice signs of disease, like yellow, brown, or black spots, don’t panic! Bring in a cutting to us in a zipped plastic bag at Royal City Nursery, and we can help you diagnose the issue (and find a solution!).
But what about pests? Pests are a fascinating topic, and we’ve put a lot of effort into developing resources to help you manage them as you find them. Here are a few you can refer to, depending on what you’re struggling with.
- If the pest you’re struggling with seems to be on the bigger side (for example, you’re waking up to entire plants chomped down to a stub!), have a look at our guide to Rodent and Pest Control: Squirrels, Skunks, Rabbits and More
- If your plants are looking like someone has been taking a hole punch to them, you’re likely dealing with bugs! Read our guide on Controlling Japanese Beetles, Aphids, Ants, and Caterpillars.
- If you’re looking to prevent pests in the first place, the best way to start is with a healthy ecosystem. This resource is a good place to start.

Keeping Them Colourful
As the summer goes on, you might notice some of that bright colour starting to fade. Deadheading is the process of pinching off spent flowers to encourage the plant to produce more, and it’s a great way to keep your garden looking great. I always encourage folks to take a little walk through each day and spend a few minutes pinching and cleaning up.
While you’re at it, you can pull any new weeds, fix anything that looks out of place, and generally keep everything managed. It’s so much less work (and much more fun) to bundle your tasks and do a little each day. This way, the work is done quickly, and all that’s left to do is stand back and admire your handiwork.
