Spring is everywhere now and I find I am needing to check the time often because days are really drawing out. Our little 4 year old Maggie pointed out that the large pink magnolias were throwing off their wooly blankets and yes they are, large fluffy bud casings are covering the ground as beautiful magnolias take center stage.They are always out before blossom in this garden.
Having seen some lovely new lavender plants on offer in Garden centers, I continue to cut back mine as they begin to put out new growth, really old woody bushes can be cut back hard to encourage new lower growth, if they do not respond it may be time to replace them. Newer lavender plants just need a hair cut and fed manure enriched compost and a little lime.
Softer shrubs that are encroaching on drive and walkways can be trimmed back , they will soon recover with new spring growth. I have been reducing the height on some of my taller shrubs like phebaliums, pittosporums, psudopanax and other busy natives. You can do this if height is a problem without spoiling the shape of shrubs. What I do is cut out the center branch down to where the other branches bush out, this removes the natural point at the top of the shrub and will sometimes reduce the height by 2 or more meters. The shrubs will soon send up a new leader but will also put more growth into the side branching which can be trimmed into shape if a problem. With new spring growth happening this is the time to do this sort of height and width control.
A lot of climbers are in bud now ready to do their spring thing so when trimming watch you are not cutting off new buds. Hardenbergia ( happy wanderer) flowered in early winter so if the frosts haven't cut it back, it is one that can be cut back. Jasmines have been knocked
by frosts, I will leave them a bit longer until I am sure the frosts are over before trimming them.
If you have still not feed your roses do it as soon as possible! they are moving fast now and need food kept up to them if you want them to stay healthy. That goes for most plants now, If you have no time to do anything else in the garden feeding plants is a must for health and vigour to take them right through to autumn. It is well worth the effort and will minimize the spaying needed for unhealthy plants.
Now would be a good time to mention plants that resent being fed, many South African plants and Australian natives such as proteas, leucodendrons, banksias, and all grevillia's do not need feeding. I have lost some of these because they had absorbed fertiliser from neighbouring plants.
There is still time to divide hosta's while they are still not showing a lot of leaf, these dramatic shade loving perennials can really highlight a shaded spot with their fresh greens and variegated light shades. Simply lift established clumps at least 4 to 5 years old, use a sharp spade to slice them into a few good size pieces, then replant. They also look great in pots but get slug bate around them as soon as they start showing leaf or try some of the slug repellent methods that have been passed down by gardeners listed below.
Coffee Grounds: Used coffee grounds spread around plants may work.
Epsom salts sprinkled on the soil will supposedly deter slugs and also helps prevent Magnesium deficiency in your plants. Magnesium helps to deepen color, thickens petals and increases root structure.
Oat Bran: Scatter oat bran on the soil to deter slugs and snails.
Builders Sand: try barriers of sharp textured builders sand.(not beach sand)
Nut Shells: Ground walnuts shells have been known to work.
Sprigs of rosemary scattered around are said to repel slugs.
Try a mulch of pine needles, these work well around strawberry plants.
I am continuing to sow seeds under cover, the seeds I planted two weeks ago are up already and getting a weekly liquid feed of diluted worm tea. Any seed packs that recommend spring sowing will pop up now. I sow my seeds in trays of compost and soil combined with a layer of seed raising mix on the top, this way your seed raising mix will go further. Once planted cover the trays with plastic or glass, but use spacers to let air circulate between the plastic / glass and tray.
Vegetables:
If you plan to grow vegetables this summer get the garden ready now by digging in some weed free compost, then let the soil settle for a while before planting. Plant seedlings later in the day when the heat is out of the sun, then keep moist until they take hold and start growing. Watering is best done at the start of the day. In area's you do not plan to plant out for a while why do tired soil a favor and sow a green crop to add humus. Mustard, lupine, barley or wheat they will germinate in no time. If you do decide to do this dig it in when lush, soft and green, don't let it get to the flowering, stalky stage because it takes too long to break down.
Fruit This is also the time to give fruiting shrubs and trees a dressing of pot ash to help with fruiting. Deciduous fruit trees and everything in the way of small fruit should be planted in August at the latest. Now is a good time to shift citrus trees.
