Plant Food Perth

Feed what you are actually growing.

Rose and flower food, and fruit and citrus food. A general fertiliser is a compromise between the two — these are the targeted ones, high analysis and fast acting, with iron through them for leaf colour.

Both are built for hungry, fast-growing plants, which is exactly why neither belongs anywhere near an Australian native. We are between native feeds at the moment, so if that is what you are after, talk to us in the yard before you buy anything.

How much plant food do you need?

By the plant, not by the metre

These are concentrated feeds applied plant by plant, so the useful number is how many plants a bag does rather than how many square metres it covers.

Both come in 1.5kg, 2.5kg, 5kg and 10kg. Spread to the drip line, keep the granules 10cm off the base, water in, and never put them on the leaves.

Ask us what you need
ProductBagWhat it feeds
Black Marvel Rose & Flower Food5kgOver 150 established roses, at 30g each. Half that rate for miniatures and anything in a pot.
Black Marvel Fruit & Citrus Food5kgAbout 100m², at 50g/m² out to the drip line.
Banksias, grevilleas, hakeas—Neither of these. Both are high phosphorus and phosphorus is what kills proteaceae. Come and talk to us before you feed a native.

Apply roses two to three weeks after pruning, then every four to eight weeks until winter. Fruit and citrus every six to eight weeks through the growing season. Not in the middle of a hot day.

How to choose a plant food

Four things that actually decide it

  • Phosphorus, and what it kills

    Phosphorus is the nutrient that gives Australian natives trouble, and the 1 in the middle of 6:1:1 is the whole reason the native food exists. Low phosphorus is not no phosphorus, so banksias, grevilleas, hakeas and waratahs still want the lower end of the rate.

  • Per plant, or per square metre

    The rose food is dosed per plant — 30 grams for an established in-ground rose, 10 for a new or bare-rooted one. The citrus and native foods are dosed per square metre. Knowing which you are working in stops you overfeeding by a factor of ten.

  • Keep it off the leaves

    These are granular feeds and they burn foliage if they sit on it. Spread out to the drip line, no closer than 10cm to the base, wash any strays off the leaves, and water in. Not in the middle of a hot day.

  • Timing beats quantity

    Roses start two to three weeks after pruning then every four to eight weeks until winter. Citrus go every six to eight weeks through the growing season. Natives get spring and autumn and nothing in between — there is no benefit to a third feed.

Plant food FAQs

What we get asked at the counter

  • What plant food is safe for natives?

    Neither of the two on this page. Both are high in phosphorus, and phosphorus is what kills banksias, grevilleas, hakeas and waratahs. We are between native feeds at the moment, so come and talk to us in the yard rather than guessing — a native food is a genuinely different product, not a different label on the same one.

  • Can I just use the rose or citrus food on a native?

    No, and this is the one to get right. Both sit around 12 parts nitrogen to 1 or 2 parts phosphorus, which is fine for a hungry rose and enough phosphorus to kill a banksia or a grevillea. Phosphorus toxicity in the proteaceae is not a slow decline either — plants go down over a season. Ask at the counter instead.

  • Do natives need feeding at all?

    Often not. A native growing well in the ground it evolved for is usually better left alone, and more plants are lost to being fed than to being ignored. If yours is genuinely struggling, that is worth a conversation about the soil before it becomes a conversation about fertiliser.

  • How much rose food does an established rose take?

    Thirty grams per plant for an established in-ground rose, and 10 grams for a new or bare-rooted one. Miniature and potted roses take half the in-ground rate. A 5kg bag feeds over 150 established roses, so it goes a long way in a home garden.

  • How often should I feed citrus?

    Every six to eight weeks through the growing season, at 50 grams per square metre spread out to the drip line and watered in. Apples, pears and stone fruit take the same rate but at different times — when the buds form, and again as the fruit ripens.

  • Can I use rose food on other flowering plants?

    Yes. Richgro give the same rates for flowering plants generally — 30 grams in the ground and 10 grams in a pot. The high potash is aimed at flowering rather than at roses specifically.

  • Why do the granules have to stay off the leaves?

    Because they burn foliage if they sit on it. Spread them onto the soil out to the drip line, keep them at least 10cm clear of the base of the plant, and wash or brush any strays off before you water in.

  • Can I feed in the middle of summer?

    Not in the heat of the day. Feed early morning or late afternoon with a good watering in behind it, whatever the product. For natives, skip summer altogether — spring and autumn is the timing.

  • Which plant food is right for my garden?

    Tell us what you are growing rather than which product you were going to buy. A rose, a lemon tree and a banksia want three genuinely different analyses, and the difference between them is not marketing. If we do not stock what your plant actually wants, we will tell you.
